My analysis for the Q2 2026 GDPNow estimate as of June 15, 2026, is based on a synthesis of recent economic momentum, significant geopolitical shocks, and the mechanical nature of the Atlanta Fed’s model. The most likely prediction is 2.11%, with a 50% chance of falling between 1.51% and 2.65%.
First, I examined the recent economic baseline. The Q1 2026 GDPNow estimate ended at a weak 1.2% in late April, down from 3.1% earlier in the quarter. This deceleration was driven by the ‘Iran war fuel crisis’ and the implementation of a 10% universal tariff in February 2026. However, leading indicators from March and April 2026 show signs of resilience: the ISM Manufacturing PMI rose to 52.7, and nominal retail sales for March grew by 1.7%. These expansionary readings suggest that while real growth is pressured by energy prices, the economy is not currently in a contractionary phase.
Second, I weighted the impact of the supply-side shocks. Brent crude oil prices exceeding $105 per barrel and the closure of the Strait of Hormuz represent a massive cost-push inflationary pressure. Historical data suggests such shocks typically reduce growth by 0.6 to 0.8 percentage points. The Atlanta Fed model will be balancing these higher energy costs against resilient nominal spending. Because GDPNow reacts to high-frequency data (like retail sales and industrial production), the estimate as of June 15 will have incorporated the full ‘Advance’ Q1 GDP report and primary April data points.
Third, I considered external forecasts and historical model behavior. Polymarket data suggests a mode of 1.5% to 2.0% for Q1, while full-year 2026 expectations remain more bullish (above 2.5%). This implies an expectation that the economy will absorb the Q1 shocks and accelerate in Q2. Historically, early-quarter GDPNow estimates (like June 15 for Q2) tend to be more volatile and occasionally more optimistic than final figures. In Q2 2025, the estimate was 3.8% in early June before settling at 2.9% in late July.
Finally, I constructed a distribution that reflects these competing forces. The central estimate of 2.11% accounts for a modest rebound from the weak Q1 finish, driven by steady service sector activity and expansionary manufacturing PMI. A downside tail accounts for the risk that the 10% universal tariff and energy prices cause a sharper-than-expected contraction in real personal consumption expenditures (PCE). The 50% HDI of 1.51% to 2.65% reflects the inherent volatility of the GDPNow model and the uncertainty of the 2026 geopolitical environment.
The question asks what the Atlanta Fed’s GDPNow Q2‑2026 nowcast will print for the final pre‑cutoff update—effectively the June 9, 2026 release unless the Fed posts an unscheduled update (forecasters assign ~10–15% chance to a late extra print). All teams agree the Jun 9 print is the mechanically relevant resolution and that historical mid‑June GDPNow values (excluding pandemic outliers) center near ~2.6% with an empirical SD ~1.0–1.3%. Given the current hard‑data mix—March/April PCE and retail, delayed housing/ construction data, April trade (with annual revisions) and wholesale inventories—forecasters shade that prior down: the blended central forecast is about 2.0% (σ ~0.9–1.3%), with GDPNow particularly sensitive to net exports, inventories, and the PCE deflator. April data and the June 9 trade/revision batch could move the nowcast by 1–1.5 percentage points in either direction, and inventory/trade surprises produce fat tails. Tail probabilities are small but non‑negligible (~4% each) for extreme outcomes below –2% or above +4%, and forecasters emphasize monitoring the Atlanta Fed schedule and the April/early‑June releases most closely.
Forecast: Probability distribution:
We are forecasting the Atlanta Fed GDPNow (Q2 2026) value that is most recently published on or before 2026-06-15 23:59 UTC. A key operational detail (not always handled correctly by casual forecasters) is that GDPNow updates are not daily; based on the posted GDPNow release-date schedule cited by one analyst, the last scheduled update before the June 15 cutoff is likely in the prior week (e.g., around June 9), with the next one after the cutoff. That means the resolving value will reflect substantial but not complete Q2 source data (many April releases and some May releases), and it can still move meaningfully due to trade/inventory and consumption surprises.
Across the four analyst distributions, medians range from ~1.1% to ~2.6%. The higher-median forecast (Forecaster 1) appears somewhat tight given historical mid-quarter GDPNow volatility, while the lowest-median forecast (Forecaster 3) may overweight downside relative to typical mid-quarter nowcast centers. Forecasters 2 and 4 incorporate larger macro-shock narratives and produce wider tails; however, some of that reasoning depends on specific geopolitical/tariff claims that cannot be independently verified here, so I treat those as increasing uncertainty rather than shifting the center extremely.
Synthesizing these, I center the distribution near ~1.8% (a compromise between the high and low medians), keep substantial mass from slightly negative to low-3s, and retain a modest right tail above the open upper bound (reflecting that GDPNow can exceed 4% in some quarters, though I do not think that is the dominant scenario). I do not place p5 below -2.0 because that would implicitly assert at least ~5% probability of being below -2%, which seems higher than warranted given the question creator’s stated expectations and typical mid-quarter nowcast behavior.
An amateur forecast would often (a) ignore the resolution mechanic and assume there will be a June 15 update, or (b) anchor on a single contemporaneous nowcast (e.g., NY Fed) and give an overly narrow range. This forecast explicitly accounts for the likely last-update-before-cutoff logic (so we’re forecasting an early/mid-June GDPNow print), and it blends multiple analyst views to avoid both overconfidence (too-narrow, high median) and overreaction to unverified shock narratives (too-wide, heavily shifted tails). Confidence in improvement is moderate: the schedule logic is a clear win, while the macro level remains genuinely uncertain.
Forecast rationale (numeric):
— Iteration 1 — The forecasts converge on a modest positive Q2 2026 GDPNow reading, centered in the mid‑1% range SAAR. The core logic is:
Overall, the shared view is that Q2 GDPNow should remain mildly positive, with moderate upside from inventories/investment but significant uncertainty from trade and energy-related risks.
— Iteration 2 — The forecasts converge on a modest-growth baseline, with the latest Q2 2026 GDPNow estimate likely around 1.4% by June 15, 2026. The reasoning is anchored in the most recent visible GDPNow reading for Q1 2026 of about 1.2%, implying a similar low-single-digit growth environment unless new data materially shifts the picture.
Key drivers behind the estimate:
Overall, the view is mildly right-skewed: positive growth is more likely than recession, but downside tail risk is still meaningful. The central expectation is for a small positive Q2 reading, with most plausible outcomes clustered in the low-single-digit range rather than a sharp acceleration or contraction.
— Iteration 3 — The forecasts converge on a modestly positive GDPNow reading for Q2 2026, likely in the low single digits—roughly around 1% to 2%, with a slight tilt toward about 1.5%.
Overall, the collective reasoning points to a soft but positive Q2 GDPNow estimate, with the most plausible outcome in the 1%–2% range, and meaningful uncertainty around that center.

The research briefing outlines the expected timeline and economic factors influencing the GDPNow estimate for Q2 2026 as of June 15, 2026. The Atlanta Fed’s GDPNow model, which provides real-time estimates of GDP growth, is currently projecting a Q1 2026 growth rate of 1.2%. The model is anticipated to begin releasing estimates for Q2 2026 in early to mid-May 2026, following the advance GDP release for Q1. By June 15, 2026, it is expected that there will be approximately 4-7 updates to the Q2 estimate, incorporating significant economic data from May and early June.
The economic backdrop for Q2 2026 includes both headwinds and tailwinds. Key challenges include the ongoing Iran war affecting oil prices, low consumer sentiment, and a weakening labor market. Conversely, potential positive influences include a ceasefire leading to lower oil prices, strong retail sales, fiscal stimulus from tax rebates, and resilient manufacturing output. The briefing presents three scenarios for the GDPNow estimate: an optimistic outlook of 2.5-3.5%, a base case of 1.5-2.5%, and a pessimistic scenario of 0.0-1.5%. The uncertainty surrounding these estimates is highlighted, with historical data indicating a significant margin of error in early-quarter projections.
Sources used in the research include:
As of the most recent update on April 21, 2026, the Atlanta Fed’s GDPNow model estimates Q1 2026 real GDP growth at 1.2% (annualized, seasonally adjusted), down from 1.3% on April 9 and from an initial estimate of 3.1% on February 20 [11][12][13][14]. The next Q1 update is scheduled for April 29, 2026 [11].
This is the most critical structural factor for this question:
Risk of annulment is very low — it is virtually certain that Q2 GDPNow estimates will be publishing well before June 15.
Headwinds:
Tailwinds:
| Source | Full-Year 2026 US GDP | Notes |
|---|---|---|
| IMF | 2.3% | Baseline; “adverse” = lower [23] |
| Bloomberg Survey (90 economists) | 2.2% | April 2026 survey [24] |
| Barclays | 2.4% | Cut from higher estimate [21] |
| CapitalSpectator Median Nowcast | 2.3% (Q1) | Aggregate nowcast [16] |
Given Q4 2025 at 0.5% and Q1 2026 tracking ~1.2%, achieving ~2.2-2.3% for the full year would require a meaningful rebound in Q2-Q4. If the ceasefire holds and oil prices continue declining, Q2 could see a bounce-back. However, lagged effects of the energy shock on consumer spending and business investment could weigh on growth.
No specific prediction markets were found for the Q2 2026 GDPNow estimate as of June 15. Searches across Polymarket, Metaculus, and Kalshi returned no directly relevant markets for this specific metric. This is unsurprising given how granular the question is. General GDP growth markets exist but don’t map directly to GDPNow estimates.
Optimistic scenario (2.5-3.5%): Ceasefire holds, oil prices fall further, consumer spending rebounds as energy costs normalize, labor market stabilizes, tax rebates continue supporting demand. Initial GDPNow estimate starts higher and holds.
Base case (1.5-2.5%): Mixed signals — energy costs partially normalize but lagged effects dampen spending; labor market continues softening; fiscal support partially offsets headwinds. This is consistent with full-year forecasts of ~2.2-2.3%.
Pessimistic scenario (0.0-1.5%): Ceasefire collapses or energy prices remain elevated; consumer sentiment stays depressed; hiring freezes spread; the economy flirts with contraction. This aligns with the “adverse” IMF scenario.
Looking at the critic’s points, I need to carefully evaluate what adjustments are warranted.
The search confirms the current status:
Let me now carefully evaluate the critic’s points and adjust my forecast:
Anchoring on Q1’s 1.2%: The critic correctly notes Q1 started at 3.1% and declined to 1.2%. This 1.9pp swing shows how volatile early estimates can be. Q2 will begin fresh.
Full-year arithmetic tension: This is a compelling point. With Q4/Q1 averaging ~0.85% and full-year forecasts at 2.2-2.3%, Q2-Q4 must average ~2.7-3.0%. My 1.9% median was inconsistent with this math.
Sentiment data timing: April consumer sentiment was 98% pre-ceasefire. May/June sentiment could significantly improve.
Post-crisis relief bounce potential: The 13-week S&P winning streak and potential for rapid normalization support upside scenarios.
Current oil prices remain elevated: WTI is still ~$110/bbl, not back to pre-conflict levels. Goldman has cut consumer spending forecasts. The energy shock impact is ongoing.
San Francisco Fed analysis confirms: “Growth projections for first half of 2026 have been revised down” and “downside risks have emerged.”
Recession probability remains meaningful: The 30% recession risk isn’t eliminated by the ceasefire.
Labor market still softening: Job gains averaging only ~68K/month creates real downside risk.
Oil at $110/bbl is still a headwind: Even with ceasefire, the “One Big Beautiful Bill” fiscal stimulus may be offset by energy cost drag.
GDPNow’s early-quarter behavior: The model often starts optimistic then declines as data accumulates. By June 15, we’ll see whether initial Q2 optimism holds.
Nuveen forecasts: Full-year US growth at 2.2% similar pace to 2025, which supports mid-range Q2 expectations.
I’ll modestly increase my median from 1.9% to 2.0%, acknowledging:
But I’ll keep meaningful downside protection given:
I’ll also slightly fatten the upper tail to capture the relief-rally scenario.

Looking at the critic’s third-round analysis, the new information about the ongoing economic situation is quite compelling and requires me to make additional adjustments.
Ceasefire ≠ Economic Relief: This is the key insight. The Strait of Hormuz remains effectively closed, ships are still being seized, and oil is trading at $98-102/barrel. My earlier framing of the ceasefire as a positive economic catalyst was fundamentally flawed. The “ceasefire” is diplomatic nomenclature masking continued economic stress.
Sustained Oil Price Headwind: With Brent at ~$100 and Pentagon estimates of 6 months to clear mines from the strait, Q2 will be operating under sustained energy shock conditions. The 500 million barrels of lost supply (per Kpler) represents historic disruption that will flow through to Q2 data.
Left Tail Should Be Fatter: Given sustained $100/bbl oil, historic consumer sentiment collapse, weak labor market (68K/month), and 30% 12-month recession probability, my 10th percentile was still too optimistic.
Fiscal Stimulus is Real: Tax rebates from the “One Big Beautiful Bill Act” are mechanically supporting consumption regardless of sentiment.
Wealth Effect from Equity Recovery: The critic notes markets have “reclaimed pre-war levels” - this wealth effect provides some offset to headwinds.
Sentiment-Spending Divergence: The 2022-2023 pattern of dire sentiment with resilient spending continues to provide some optimism.
The dichotomy is striking: markets are pricing out tail risks while the real economy continues operating under crisis conditions. GDPNow by June 15 will capture an economy where:
This suggests a wider, more uncertain distribution than I had, with particular emphasis on downside risk.
I’m converging substantially toward the critic’s distribution. The new information about the functionally closed strait fundamentally changes my assessment of the ceasefire’s economic impact. I’ll accept the lower median of 1.8% and fatter left tail, while maintaining marginally more weight on the fiscal/wealth effect tailwinds.

The critic has identified a significant factor I had not adequately weighted: the IEEPA tariff ruling and its fiscal implications. Let me address this carefully.
IEEPA Refund Fiscal Impulse: The $142 billion in tariff refunds to importers is a substantial fiscal stimulus that should flow through to business spending and potentially consumer prices. This is a material positive I underweighted.
Lower Effective Tariff Rate: The reduction from 16.9% to 9.1% creates genuine headroom for economic activity, particularly for import-dependent sectors.
Yale Budget Lab Assessment: Their finding that refund fiscal impulse approximately offsets remaining tariff headwinds is credible third-party analysis that supports a more optimistic view.
Data Sequencing Advantage: By June 15, GDPNow will capture post-IEEPA trade data and potentially the initial bounce in business activity—this timing favors higher readings.
Labor Market Structural Issues: Job gains of ~68K/month and declining participation don’t reverse in weeks. This represents a genuine drag that even fiscal stimulus can’t immediately overcome.
30% Recession Probability: Bloomberg’s professional consensus deserves respect. While positive factors are accumulating, recession risk remains meaningful.
Refund Timing Uncertainty: Not all $142B will flow immediately—corporate treasury decisions, accounting processes, and reinvestment timing create lags.
Section 122 Uncertainty: The administration’s pivot creates new policy uncertainty that could dampen business investment confidence.
I now see Q2 2026 as benefiting from a “convergence of positives”:
However, structural headwinds remain:
I’ll shift my median up by 0.1pp to 2.1%, modestly widen the right tail to capture IEEPA boost potential, while maintaining appropriate left-tail weight for recession scenarios.
Updated prediction: Percentile 0.1: -1.5 Percentile 1: -0.4 Percentile 5: 0.4 Percentile 10: 0.75 Percentile 20: 1.1 Percentile 30: 1.5 Percentile 40: 1.8 Percentile 50: 2.1 Percentile 60: 2.4 Percentile 70: 2.7 Percentile 80: 3.1 Percentile 90: 3.5 Percentile 95: 4.0 Percentile 99: 4.7 Percentile 99.9: 5.6
The critic raises several compelling points that warrant adjustments:
Mathematical consistency with professional forecasts: This is the strongest criticism. If full-year 2026 GDP is forecast at 2.2-2.3%, and Q4 2025 (0.5%) and Q1 2026 (~1.2%) underperformed, then Q2-Q4 must average significantly higher—around 2.8-3.0%—to hit those targets. My median of 2.0% was arguably too conservative if those forecasts are accurate.
Stale sentiment data: The critic correctly notes that 98% of the record-low consumer sentiment reading was collected before the April 7 ceasefire. Post-ceasefire sentiment could be materially better.
Underweighting emerging tailwinds: The 15% oil price drop in two weeks, fiscal stimulus from tax rebates, and the ceasefire together create meaningful upside potential I may have underweighted.
However, I maintain some caution:
Lagged effects: Even with a ceasefire, business investment decisions and hiring plans don’t reverse overnight. The energy shock’s impact on supply chains and costs may persist.
Early-quarter measurement: The June 15 GDPNow will only have 4-7 updates and limited data. It may not fully capture the recovery momentum yet.
Ceasefire fragility: The “indefinite” ceasefire is only weeks old. Downside tail risk from potential collapse remains real.
Professional forecasts could be optimistic: With Bloomberg’s recession probability at 30%, there’s meaningful chance the economy underperforms those 2.2-2.3% full-year targets.
GDPNow’s early-quarter sensitivity: The model heavily weights employment and retail sales early in the quarter. May employment and retail data will be key—and could reflect post-ceasefire stabilization more than my initial estimate captured.
Fiscal stimulus timing: Tax rebates directly boost consumption, the largest GDP component. This is a concrete, quantifiable tailwind.
Risk asymmetry reconsideration: The upside from continued normalization may be larger than I initially assessed, while fiscal stimulus provides a floor on the downside.
I’m nudging my median up to 2.1% and widening the tails somewhat—particularly the upside—to reflect:
I’m not moving as far as the critic suggests because early-quarter GDPNow readings have high inherent uncertainty and the ceasefire is very new.
Updated prediction: Percentile 0.1: -2.2 Percentile 1: -0.9 Percentile 5: 0.1 Percentile 10: 0.6 Percentile 20: 1.1 Percentile 30: 1.5 Percentile 40: 1.8 Percentile 50: 2.1 Percentile 60: 2.4 Percentile 70: 2.7 Percentile 80: 3.0 Percentile 90: 3.5 Percentile 95: 4.0 Percentile 99: 4.8 Percentile 99.9: 5.7
The critic raises several compelling arguments that merit careful consideration:
Structural break from ceasefire: The critic correctly identifies that Q2 begins after the April 7 ceasefire, whereas Q1 bore the full brunt of the Iran crisis. I was anchoring too heavily on Q1’s trajectory without fully accounting for this fundamental shift in conditions.
Stale sentiment data: The 98% pre-ceasefire interview timing is crucial. The 47.6 reading, while alarming, doesn’t reflect current conditions and could rebound significantly.
Consistency with professional forecasts: The math is compelling - if full-year forecasts are 2.2-2.3% and Q4/Q1 averaged roughly 0.85%, Q2-Q4 would need to average approximately 2.5-2.8% to hit annual targets. My 1.9% median was slightly inconsistent with this.
Inventory front-loading: This dynamic ahead of potential tariff changes could boost early GDPNow readings, which I neglected.
Labor market concerns remain valid: 68K/month job gains and “true” unemployment near 5% represent real headwinds that won’t reverse quickly from a ceasefire.
Behavioral scarring: Consumer confidence at record lows suggests deep pessimism that doesn’t fully reverse in 6-8 weeks, even with positive news.
Lagged energy effects: The March CPI surge and accumulated price increases have already impacted real purchasing power. This damage is done for early Q2.
Q1 GDPNow evolution: Q1 started at 3.1% in February and declined to 1.2% by April - a 1.9pp drop. Early-quarter readings often trend downward as more data arrives. The June 15 reading may be somewhat optimistic relative to final.
Strong March retail momentum (+1.7%) provides a positive impulse entering Q2 that could lift early readings.
I accept the critic’s main thrust - my forecast was slightly pessimistic given the ceasefire catalyst and implied professional forecast requirements. I’ll shift my median up to 2.0% and widen the upside tail to better capture the ceasefire-driven relief scenario, while maintaining appropriate weight on downside risks from labor market and lagged energy effects.

Agent Forecast (numeric, confidence: medium)
Base Rate: Q1 2026 GDPNow ended at 1.2% (down from 3.0% in early February) with only partial Iran war exposure. Q4 2025 advance estimate was 1.4%, final 0.5%. Professional 2026 full-year consensus is 1.8-2.2% (EY-Parthenon, S&P Global), implying quarterly rates averaging ~1.5-2.0% but with Q2 facing the largest headwinds. By mid-June, Q2 GDPNow will have ingested April retail sales, April employment, May ISM/PMI, and likely the May employment report — meaningful data but before the full consumer-spending pullback shows up.

Reviewer Panel:
Reviewer (reasoning)
The draft forecast’s biggest weakness is its reliance on broad full-year consensus forecasts and qualitative Iran-war headwind language rather than on the specific mix and timing of data releases that feed GDPNow through mid-June. It also fails to anchor to historical Q2 mid-quarter revisions of GDPNow, which often show systematic drift that contradicts the assumed early-quarter anchoring near consensus. Finally, it does not specify the release date of the June 15 estimate, violating the resolution criteria.
Objections:
Reviewer (calibration)
The draft forecast’s primary weakness is its reliance on full-year 2026 GDP growth forecasts to anchor a real-time, mid-quarter GDPNow estimate for Q2. GDPNow is highly responsive to immediate data, and full-year projections often smooth over significant quarterly volatility, especially in the face of sudden economic shocks. The forecast acknowledges severe headwinds but appears to underweight their combined impact, leading to an overly optimistic central estimate for Q2.

Adjustment Rationale:
Adjusted central estimate from ~1.5% down to ~1.0-1.25%, making the 1-1.5% bin modal instead of 1.5-2%. The calibration reviewer correctly noted that Q1 GDPNow settled at 1.2% under only partial Iran exposure, and Q2 faces the full-quarter oil shock plus worse consumer sentiment — so the central tendency should sit at or below Q1’s final reading, not above it. The reasoning reviewer correctly flagged that I over-anchored to full-year 2026 consensus forecasts (1.8-2.2%) which smooth quarterly volatility and don’t directly map to a mid-quarter GDPNow read that ingests high-frequency data. I shifted ~6pp of probability mass from the 1.5-2.5% bins to the 0.5-1.5% bins. Tail probabilities widened slightly on both sides (more weight in -1 to 0 and Above 4) to acknowledge the reviewer divergence (30% vs 88.5%) reflecting genuine uncertainty about Iran ceasefire trajectory and the April 30 Q1 advance print, which will anchor Q2 expectations. Tempered the ‘record-low consumer sentiment’ and ‘GDPNow drifts down at mid-quarter’ phrasing per fact-checker — the underlying signal (sentiment at 2022 recession levels; Q1 path from 3.0%→1.2%) supports the direction but not those specific generalizations.

Model’s Answer:
Current State: As of April 25, 2026, no Q2 2026 GDPNow estimate has been published. The first Q2 nowcast is expected around April 30, coinciding with the Q1 advance GDP release. The last Q1 2026 GDPNow estimate was 1.2% (April 21), having declined from 5.3% in mid-January — illustrating the model’s extreme sensitivity to incoming data.
Comparable Anchors:
Why a low outcome could result: The “2026 Iran war fuel crisis” is described as potentially “the largest oil supply shock in history,” which could severely depress consumer spending, transportation, and manufacturing. Escalating IEEPA tariffs could further reduce trade volumes and increase input costs. If both shocks compound, GDPNow could turn negative. Historical precedent: Q1 2025 GDPNow crashed from +3.9% to -2.7% mid-quarter. Probability of estimate below 0%: ~12-15%.
Why a high outcome could result: The US is now a major energy producer, partially offsetting oil shock impacts. A weak Q1 often sees mechanical rebound effects in Q2 (inventory restocking, deferred spending). The NY Fed’s 2.8% suggests initial Q2 data flow isn’t recessionary. Tariff uncertainty could partially resolve. Probability of estimate above 3.5%: ~12-15%.
Assumption 1: No severe escalation of Iran war causing catastrophic oil disruption. Failure probability: ~15%. If a major escalation occurs (e.g., Strait of Hormuz closure), GDPNow could swing to -1% to -3%.
Assumption 2: Tariff policy doesn’t dramatically tighten further. Failure probability: ~20%. Additional tariff rounds could significantly depress business investment and trade components.
Assumption 3: Labor market remains stable through May data. Failure probability: ~10%. A sudden employment deterioration would sharply lower the nowcast.
By June 15, approximately 5-7 GDPNow updates will have been published incorporating April and May economic data (employment, retail sales, ISM, trade, PCE, housing). The estimate will be well-informed but still uncertain.
I center my distribution around 1.7%, reflecting:
The 90% confidence interval spans roughly -0.3% to 3.6%, which is appropriately wide given the unprecedented combination of oil supply shock plus tariff uncertainty.

I’ll work through this systematically as a superforecaster.
The most recently published Atlanta Fed GDPNow estimate for Q2 2026, published on or before June 15, 2026 23:59 UTC.
Strait of Hormuz status / oil price trajectory (weight: 0.35): The single most consequential factor. If Strait remains closed, oil stays above $100, dragging consumer spending, net exports, and investment. Prediction markets give only 42% probability of normal traffic before June 1 [S40]. This directly feeds into GDPNow’s consumption and trade components.
April–May economic data releases feeding GDPNow (weight: 0.30): April NFP (May 1), April retail sales (May 14), May CPI (June 10), May NFP (June 5) are the primary mechanical inputs. Record-low consumer sentiment (47.6) [S70] suggests these will be weak, but the US labor market has shown resilience.
Q1 2026 advance GDP release (April 30) and baseline calibration (weight: 0.15): WSJ consensus at 2.1–2.4% vs. GDPNow at 1.2% [S74][S75]. If BEA validates the higher number, Q2 GDPNow may start from a higher base. If it validates GDPNow’s pessimism, the downward trajectory continues.
Net exports / trade balance (weight: 0.12): The April 2 GDPNow update already showed net exports contributing -0.76pp [S7]. With Strait closed, import costs rise but volumes may fall — ambiguous net effect, but likely negative.
Consumer spending resilience vs. sentiment collapse (weight: 0.08): Record-low sentiment (47.6) [S70] historically predicts spending weakness, but the relationship has been noisy post-COVID. This feeds directly into GDPNow’s PCE component.
As of April 25, 2026:
Mixed, leaning cloudlike. GDPNow itself is a mechanical/clocklike model, but the inputs (geopolitical resolution, oil prices, consumer behavior) are highly cloudlike. The Iran war introduces genuine novelty. The question is moderately suited to base-rate anchoring for the mechanical model behavior, but the geopolitical uncertainty creates fat tails.
Wrong class: “Average GDPNow readings over recent quarters” (would suggest ~1.5–2.5%) Better class: “GDPNow readings during quarters where a major supply shock was already fully embedded at the quarter’s start, with oil prices elevated and consumer sentiment depressed.” The Q2 2022 analog (0.0% on June 15 [S71]) is the closest, but the current shock is described as more severe. Q2 2020 is too extreme (COVID lockdowns).
Thin — 2–5 loose analogies:
The Q2 2022 analog is most relevant but imperfect. The current shock is more severe (Goldman calls it “most significant oil supply shock in history” [S31]) but the US is a net oil exporter, providing partial insulation [S29].
Most likely scenario to make this forecast wrong: Strait reopens in May, oil falls to $80–85, consumer spending rebounds → GDPNow tracks 2.0%+ (upside miss). This would push the forecast significantly higher than my central estimate.
Approximately normal with left skew (longer left tail). The downside scenarios (Strait stays closed, recession materializes) are more numerous and severe. I’ll model this as roughly normal centered around 0.5–1.0% with SD ~1.2–1.5%, skewed left.
Scenario 1: Strait remains closed through June, oil above $110, data deteriorates sharply
Scenario 2: Strait partially open/intermittent, oil $90–105, weak but positive data
Scenario 3: Ceasefire holds, Strait partially reopens in May, oil falls to $85–95
Scenario 4: Full Strait reopening, oil back to $75–85, strong data
Scenario 5: Severe escalation, recession materializes, oil above $130
Weighted average check: (0.25 × -1.2) + (0.30 × 0.3) + (0.28 × 1.4) + (0.12 × 2.3) + (0.05 × -2.5) = -0.30 + 0.09 + 0.392 + 0.276 + (-0.125) = 0.333%
This is consistent with my view that the central estimate sits around 0.3–0.5%, reflecting the left skew from downside risks.
51 days remain. The Q2 GDPNow will have been running ~6–7 weeks by June 15, with multiple data updates. If the window were halved (to ~25 days), we’d only have the initial 1–2 GDPNow estimates, which tend to be higher (less data incorporated). If doubled, we’d be near the BEA advance release, where GDPNow tends to converge to its final reading. The 51-day window is actually well-suited — we’ll have meaningful data but not the final convergence.
Given the weighted mean ~0.33%, left skew, and SD ~1.3–1.5%:
Percentile 10: -1.8 Percentile 20: -0.8 Percentile 40: 0.2 Percentile 60: 0.9 Percentile 80: 1.8 Percentile 90: 2.5
I’ll work through this systematically as a superforecaster.
The most recently published GDPNow estimate for Q2 2026 on or before June 15, 2026 23:59 UTC.
Strait of Hormuz status / oil price trajectory through May-June 2026 (weight: 0.35): The single most consequential factor. Strait remains effectively closed as of April 25 [S40]. Oil at $105-107 Brent [S39]. Prediction markets: only 42% chance of normal traffic before June 1 [S40]. This directly affects consumer spending, trade balance, and inflation.
April-May economic data releases feeding GDPNow (weight: 0.30): April NFP (May 1), April retail sales (May 14), May CPI (June 10), May NFP (June 5). Consumer sentiment at record low 47.6 [S70] suggests these will be weak. GDPNow is purely mechanical [S3] — it will reflect whatever these data show.
Q1 2026 BEA advance GDP release (April 30) and its calibration effect (weight: 0.15): WSJ consensus is +2.1-2.4% vs. GDPNow’s 1.2% [S74][S75]. If BEA comes in near consensus, Q2 GDPNow may start from a higher base; if it validates 1.2%, pessimistic tracking continues.
Net exports / trade balance dynamics (weight: 0.12): Q1 GDPNow was dragged by net exports (-0.76pp on April 2 update) [S7]. With Strait closed, import volumes may fall but oil import costs rise. Complex and uncertain.
Consumer spending resilience vs. sentiment collapse (weight: 0.08): Record-low sentiment (47.6) [S70] historically predicts spending weakness, but actual spending data sometimes diverges from sentiment surveys.
Mixed, leaning cloudlike. GDPNow itself is clocklike (mechanical model, rule-governed updates), but the inputs — especially the geopolitical resolution of the Iran war and Strait closure — are highly cloudlike. The question is partially suited to base-rate anchoring (GDPNow’s historical distribution) but the current shock is genuinely novel.
Wrong class: “Typical Q2 GDPNow readings” (which would anchor near the 5-year mean of 2.49% [S10]).
Better class: “GDPNow readings mid-quarter during significant supply/demand shocks with elevated recession risk.” The Q2 2022 analog (GDPNow at 0.0% on June 15, 2022 [S71], ultimately -1.2% final [S72]) is the closest comparable, though the current shock is described as more severe.
Thin — 2-5 loose analogies:
The Q2 2022 analog is most relevant: similar energy shock context, mid-quarter reading, but current shock is described as more severe. I’ll use 0.0% as a reference anchor but adjust downward given the more severe current conditions.
The single scenario most likely to make this forecast wrong: The Strait of Hormuz reopens substantively in May 2026 (prediction markets give 42% probability before June 1 [S40]), oil falls back to $80-85, consumer spending rebounds, and GDPNow tracks toward 1.5-2.5%. This would push the estimate significantly higher than my central estimate.
In the other direction: diplomatic collapse, oil surges to $130+, recession materializes, GDPNow goes deeply negative.
Approximately normal with left skew (negative tail is longer). The downside scenarios are more numerous and more severe than upside scenarios. The distribution is centered somewhere between -0.5% and 0.5%, with meaningful probability mass below -1.0% and limited probability above 2.0%.
The variable is a single point estimate (not a min/max over a window), so no extreme-value adjustment needed. However, GDPNow can move substantially between updates — the Q1 2026 trajectory shows 1.9pp decline over ~2 months [S4][S7].
Scenario 1: Strait remains closed, oil above $110, economic deterioration (probability: 0.30)
Scenario 2: Strait partially open/intermittent, oil $90-105, weak but positive data (probability: 0.35)
Scenario 3: Ceasefire holds, Strait partially reopens May, oil falls to $85-95 (probability: 0.22)
Scenario 4: Full Strait reopening, oil back to $75-85, strong rebound (probability: 0.08)
Scenario 5: Severe escalation, oil above $130, recession clearly underway (probability: 0.05)
Weighted average check: (0.30 × -1.2) + (0.35 × 0.2) + (0.22 × 1.3) + (0.08 × 2.1) + (0.05 × -2.5) = -0.36 + 0.07 + 0.286 + 0.168 + (-0.125) = 0.039% ≈ 0.0%
This is consistent with the Q2 2022 analog (0.0% on June 15, 2022 [S71]) and reflects the left-skewed distribution where severe downside scenarios pull the mean down from a modal value around 0.2%.
51 days remain. The Q2 GDPNow cycle will have been running ~6-7 weeks by June 15. If the window were halved (~25 days), we’d only have 2-3 GDPNow updates and the initial estimate would dominate — likely higher (less negative) since the full shock data wouldn’t yet be incorporated. If doubled (to ~100 days), we’d be near the BEA advance release and GDPNow would have fully incorporated all Q2 data — likely more negative. The current 51-day window captures the mid-quarter reading, analogous to June 15, 2022.
Given the weighted mean of ~0.0%, left-skewed distribution, and the Q2 2022 analog:
Percentile 10: -2.0 Percentile 20: -1.2 Percentile 40: -0.2 Percentile 60: 0.5 Percentile 80: 1.3 Percentile 90: 2.0
Target variable
The outcome is the most recently published Atlanta Fed GDPNow estimate for Q2 2026, expressed as annualized real GDP growth (%), with publication timestamp on or before June 15, 2026 23:59 UTC. If Atlanta Fed posts multiple Q2 estimates before then, only the latest one counts. If none exists, annulment, but that is very unlikely given the normal publication cycle [S3][S11].
Current state
As of today, no Q2 2026 GDPNow estimate exists yet. The model is still on Q1 2026 at 1.2%, last updated April 21, with next update April 29 [S3][S7]. The advance Q1 GDP release is April 30, which should trigger the Q2 GDPNow cycle in early May [S11][S74][S75]. So the June 15 resolving value will almost certainly be a mid-quarter nowcast, informed by April hard data and much of May data, but likely not by May retail sales if released after the cutoff [S11].
The macro backdrop is clearly weaker than normal: oil shock, partial Strait closure, very weak sentiment, elevated inflation, and some private forecasters warning Q2 could approach stall speed or contraction [S21][S34][S39][S70]. Against that, the US is not a pure oil importer anymore, and many GDPNow moves depend on specific source data components, especially trade, inventories, real consumption, and industrial production.
Key drivers (weighted)
April–May hard consumption data entering GDPNow, especially retail sales / real PCE proxies — 0.30
This is the cleanest channel from the oil shock and sentiment collapse into Q2 growth. If consumers retrench materially, June 15 GDPNow falls toward zero or below.
Net exports and goods trade effects in the model — 0.24
Q1 GDPNow was materially hit by trade [S7]. Oil-price and shipping disruption can create large trade swings; GDPNow is often very sensitive to this component.
Industrial production / business fixed investment / inventories from manufacturing-side data — 0.18
Energy shock and supply disruptions can depress output, but inventory rebuilding or defense/energy capex can partially offset.
Whether the Strait of Hormuz remains effectively disrupted through May/early June, keeping oil near or above $100 — 0.18
This is an upstream causal driver affecting inflation, spending, transport, and trade. Prediction markets imply only partial odds of normalization by June [S40].
Model-level tendency of GDPNow to undershoot or overshoot in this episode, inferred from Q1 advance GDP vs GDPNow gap — 0.10
If the Q1 advance print comes in much stronger than GDPNow’s 1.2%, that would modestly raise my expectation for Q2 tracking. Still, the resolving variable is GDPNow itself, not BEA GDP.
System regularity
This is mixed. It is partly clocklike because GDPNow is a rule-based mechanical model with known update cadence and data inputs [S3]. But it is also cloudlike because the underlying quarter is being shaped by a geopolitical oil shock and shipping disruption, which can create non-linear moves in trade, prices, and consumption. So base rates help, but should be downweighted versus current-event adjustments.
Wrong reference class trap
A misleading reference class is “US quarterly GDP growth during oil shocks”. That is too broad and targets the wrong variable.
A better reference class is “mid-quarter Atlanta Fed GDPNow readings around June 15 during quarters with abrupt macro deterioration or energy/trade shocks”—for example 2022 energy/inflation shock quarters and other volatile nowcast episodes. Even better: the distribution of GDPNow levels about 6–7 weeks into a quarter after weak consumer/trade data.
Reference class
Assessment: thin to moderate, closer to thin for the exact setup.
We have a few useful analogues:
So I would not compute a strong mechanical base rate from this. The best anchor is: mid-June GDPNow often still has room to move, but can already be near zero in weak quarters; current conditions look worse than average and somewhat worse than 2022, though far less catastrophic than 2020.
Outside view
Normal-ish mid-quarter GDPNow readings center around roughly the low-2s, consistent with the 1-year/5-year averages cited in the brief [S10]. But:
That pushes the outside-view baseline for June 15 Q2 GDPNow down from something like ~2% toward something like 0.5% to 1.0% before considering further downside asymmetry.
Inside view adjustment
Main adjustment is downward because the June 15 reading will include:
Countervailing considerations:
Net: mean below 1, mode around low positive or mildly negative territory, left tail materially larger than right tail.
Key unknowns
Single most likely way this forecast is wrong in hindsight:
A rapid de-escalation/reopening in May plus surprisingly resilient real consumer and production data causes GDPNow to sit around 1.5%–2.2%, meaning I would be too pessimistic.
Distribution shape
For a nowcast level like this, the right starting family is approximately normal, but here I would use a left-skewed mixture distribution:
So the distribution is negatively skewed, not symmetric.
Scenario mixture
Oil shock persists; trade and consumer data crack
Partial disruption; economy near stall speed
Weak but still positive growth; data prove more resilient than surveys
De-escalation in May; oil falls and GDPNow rebounds
Weighted average of central values
0.25×(-1.1) + 0.35×0.1 + 0.28×0.9 + 0.12×1.9 = 0.24.
That feels directionally right for the mean: just above zero, with downside skew. The median should be somewhat above zero but below 0.5.
Check:
Timeframe
There are 51 days left. That is enough time for several meaningful data releases and multiple GDPNow revisions, so current uncertainty is still substantial.
So a mid-June forecast should not be too extreme unless there is strong evidence by then; that keeps me from centering below zero despite the adverse backdrop.

Target variable
The Atlanta Fed’s GDPNow point estimate (annual‐rate % change in real U.S. GDP) for 2026 Q2 that is the most recent update timestamped on or before 15 Jun 2026 23:59 UTC.
Key drivers (weights sum to 1.0)
Current state (25 Apr 2026)
• No 2026 Q2 GDPNow estimate has appeared yet.
• 2026 Q1 GDPNow sits at 1.2 %. The BEA advance 2026 Q1 print will post on 30 Apr; Street expects 2.2 %.
• The Strait of Hormuz has been effectively closed since 28 Feb; Brent ≈ 105 USD/bbl.
• Consumer sentiment hit a record low 47.6 in April; forecasters have shaved 2026 growth to ≈ 2 %.
System regularity
Mixed. GDPNow itself is clock-like (transparent formula, rich historical record), but the exogenous input stream—an oil-shock superimposed on normal data—is cloud-like. A reference-class anchor is helpful but must be tempered for current shock magnitude.
Wrong reference class trap
Superficial: “overall U.S. GDP growth in oil shocks.”
Better: “GDPNow mid-quarter readings (≈ day 75 of quarter) across 2015–2025, with and without large shocks.”
Reference class
Moderate (10 close analogues: Q2 readings for 2015–2025). Mean ≈ 1.5 %, middle 80 % range ≈ –2 % to 3 %. 2020 COVID outlier at –50 % excluded.
Key unknowns
• Whether the Strait re-opens before mid-June (42 % odds by 1 Jun per markets).
• Magnitude/sign of April retail sales and May payrolls.
• BEA advance 2026 Q1 print: if it validates Street (≈ 2.2 %), GDPNow may start Q2 0.7–1 pp higher than many expect.
Biggest “surprise” risk: a negotiated maritime corridor in May that pulls Brent below 85 USD/bbl and jolts consumption upward—would push the forecast higher.
Distribution shape
Left-skewed, roughly piece-wise uniform across scenarios; fat lower tail because oil-shock downside exceeds upside rebound potential. Domain is open; tails bounded only by extreme GDPNow behavior (historical min –53 %, max +13 %).
Scenario mixture (covering 100 %)
A. Prolonged blockade, oil > 120 USD, weak data
Weight 0.25 | Central –1.7 % | Within-scenario ±0.5 pp (–2.5 to –1.0)
B. Partial flows, oil 95–110 USD, flat demand
Weight 0.40 | Central 0.0 % | Spread ±0.5 pp (–0.5 to 0.5)
C. Ceasefire, oil drifts to 90 USD, resilient spending
Weight 0.20 | Central 1.2 % | Spread ±0.5 pp (0.7 to 1.7)
D. Corridor opens mid-May, oil 80–90 USD, data surprise up
Weight 0.12 | Central 2.3 % | Spread ±0.5 pp (1.8 to 2.8)
E. Full reopening + demand snap-back, oil < 75 USD
Weight 0.03 | Central 3.4 % | Spread ±0.5 pp (2.9 to 4.0)
Weighted mean = +0.19 % (matches intuitive “near-zero with downside tilt”).
10th percentile lies in scenario A; 90th in scenario D, satisfying tail checks.
Timeframe sensitivity
51 days remain. Halving the window would drop three major data releases and widen uncertainty; doubling would let most Q2 source data land, materially narrowing the spread. Current window captures the model at roughly half-filled information, so today’s broad fan is appropriate.

Key drivers (weights sum = 1.0)
Current state (25 Apr 2026)
• GDPNow is still on 2026 Q1 (1.2 %), next update 29 Apr.
• Advance 2026 Q1 GDP prints 30 Apr. That release historically starts the Q2 GDPNow cycle within 1-3 business days.
• Iran war has kept the Strait of Hormuz effectively closed since 28 Feb; Brent ~$105–107. Consumer sentiment collapsed to 47.6 (Apr).
• Street consensus has already sliced full-year US growth to ~2 % and assigns 25-35 % recession risk.
• Prediction markets put only a 42 % chance that tanker traffic normalises before 1 Jun.
All of this loads the early Q2 data with downside bias going into the period that will shape the 15 Jun reading.
System regularity
Mixed. GDPNow itself is clock-like (rule-based model, transparent formulas). The underlying economy over a 45-day horizon, especially into a war-driven oil shock, is cloud-like. We can anchor to past mid-quarter GDPNow readings but must allow fat tails.
Wrong reference class trap
Superficial: “headline GDP growth in shocks.”
Better: “GDPNow mid-quarter estimates 6-7 weeks into a quarter since 2015” (same mechanical model, same part of the quarter).
Reference class
Moderate (≈10 reasonably comparable quarters: 2015-2025 Q2 readings around 15 Jun). Mean ≈1.8 %, st.dev ≈1.5 %, but one mega-outlier (2020 pandemic).
Key unknowns
Distribution shape
Approximately normal with a longer left tail (negative growth shocks can be larger than positive). 2020 showed tails beyond −40 %, but present context caps the downside near −3 % by 15 Jun (mechanical model only has 2½ months of data).
Scenario mixture (mutually exclusive)
Weighted mean = 0.15 %, matching an overall view that the estimate hovers just above zero with downside skew.
Timeframe check
51 days remain. Halving the window (to mid-May) would raise uncertainty because only April data would be in; doubling (to end-July) would tighten the estimate as almost the whole quarter’s data accrues. Our spread is consistent with ~1½ months of incoming data.

Per-model forecasts:
Rationale: Summary The estimate for the Atlanta Fed’s Q2 2026 GDPNow reading as of June 15, 2026, reflects a balancing act between competing macroeconomic forces. On the downside, the 2026 Iran war fuel crisis and ongoing Strait of Hormuz disruptions have caused Brent crude prices to surge, putting upward pressure on inflation and acting as a stagflationary headwind to real consumption and industrial output. Conversely, the recent Supreme Court IEEPA ruling, which struck down sweeping tariffs and reduced the trade-weighted U.S. tariff rate from 15.3% to 8.3%, provides a strong stimulative offset by lowering import costs and removing a drag on consumer spending. Baseline economic conditions heading into the quarter show Q1 GDPNow finishing at 1.2%, with a WSJ survey consensus for Q2 at 1.7%. Meanwhile, some institutional nowcasts, such as those from the NY Fed and Goldman Sachs, project stronger Q2 growth in the 2.5% to 2.8% range. The median expectation of 1.8% represents a moderate growth scenario where the stimulative effects of tariff relief offset the energy-driven headwinds, pulling the estimate modestly above the previous quarter’s finish.
Strongest Arguments for Higher Values
Strongest Arguments for Lower Values
Key Uncertainties
The Atlanta Fed’s current GDPNow release-date table shows the initial 2026:Q2 nowcast on April 30, 2026, followed by updates on May 1, 5, 7, 8, 14, 21, 28, June 1, and June 9, with the next listed update after that on June 16. The same page says release dates are subject to change, but absent such a change the resolving estimate should be the June 9, 2026 publication. (atlantafed.org)
For base rates, recent Q2 values at roughly this same point in the quarter were 0.0% on June 15, 2022; 2.2% on June 8, 2023; 3.1% on June 7, 2024 and still 3.1% on June 18, 2024; and 3.8% on June 9, 2025. That implies a simple recent-years average around 2.3%, but with a wide range from 0.0% to 3.8%, so the historical signal is moderate growth with substantial volatility. (atlantafed.org)
Current conditions are mixed but still expansionary. Atlanta GDPNow for Q1 2026 fell from 3.0% on March 2 to 1.2% on April 21, mainly because its consumption, investment, and government sub-nowcasts softened. But the New York Fed Staff Nowcast for Q1 stood at 2.4% on April 24, and the Philadelphia Fed’s Survey of Professional Forecasters shows median forecasts of 2.6% for Q1 and 2.1% for Q2 2026. I therefore treat the live Atlanta estimate as a real downside signal, but not as enough on its own to justify a sub-1% central forecast for Q2. (atlantafed.org)
The most recent official hard data also argue against an outright contractionary baseline. Advance retail and food services sales rose 1.7% month over month in March 2026, nonfarm payrolls increased by 178,000 in March, and the unemployment rate was 4.3%. BEA’s March personal income and outlays release reported disposable personal income up 0.4% and personal consumption expenditures up 0.6%. Industrial production fell 0.5% in March, but the Fed still reported that it grew at a 2.4% annual rate in Q1 overall. Inference: the economy looks softer than early-2026 Atlanta GDPNow suggested, but still more like moderate expansion than immediate recession. (census.gov)
My synthesis is to start from the recent mid-June Q2 base rate of about 2.3%, shade slightly downward toward the SPF’s 2.1% Q2 median because Atlanta’s current-quarter tracking weakened materially through April, and then add a modest offset because March consumer/income data were firm and the June 9 estimate will still be relatively early, before the later-June data that often move GDPNow more sharply. I also ignore the question stem’s more dramatic language about tariffs and energy shocks unless and until it shows up in primary-source data. That leaves me with a central estimate near 2.2% for the likely June 9 print. I set the distribution with a median a little above 2.2%, a noticeable downside tail in case April real spending, trade, or inventory data disappoint, and a thinner upside tail in case the March retail strength carries into April and May. (atlantafed.org)
I think the resolving publication date is overwhelmingly likely to be June 9, 2026. The Atlanta Fed’s current GDPNow release schedule shows Q2 2026 updates beginning on April 30, 2026, then continuing through May 1, 5, 7, 8, 14, 21, 28, June 1, June 9, June 16, June 17, June 25, July 1, July 7, July 8, July 16, July 17, July 27, and July 28. Because the cutoff in this market is June 15, 2026 at 23:59 UTC, the June 9, 2026 publication should be the latest qualifying estimate unless the Atlanta Fed makes an unscheduled change. GDPNow also says updates are usually posted 2 to 3.5 hours after the listed source-data release, and the model’s initial Q2 2026 nowcast is already scheduled for April 30, 2026, so annulment risk looks negligible. (atlantafed.org)
The key structural point is that GDPNow is a mechanical nowcast, not a judgmental forecast: the Atlanta Fed explicitly says there are no subjective adjustments, and that updates typically follow a fixed set of source releases. By the time of the June 9, 2026 update, the model will already have incorporated the April 30 Q1 advance GDP release plus personal income/outlays, May 14 retail sales and inventories, May 21 housing starts, May 28 Q1 second GDP plus April personal income/outlays and advance manufacturing/new-home sales, June 1 construction spending and ISM manufacturing, and then June 9 full trade and wholesale trade. It will not yet have the important mid-June updates for May housing starts/import-export prices (June 16) or May retail sales and inventories (June 17). So the resolving value should be informed by a lot of April hard data and some May survey data, but it will still contain meaningful model-imputation uncertainty for later-quarter components. (atlantafed.org)
For the macro backdrop, the latest published GDPNow estimate for Q1 2026 is only 1.2% as of April 21, 2026, which argues against assuming an outright boom. But the labor market is still not recessionary: March 2026 payrolls rose 178,000 and unemployment was 4.3%. Meanwhile, the March 18, 2026 FOMC median projection for full-year 2026 real GDP growth was 2.4%, and New York Fed President John Williams said on April 16, 2026 that he still expected 2% to 2.5% real GDP growth this year despite the Middle East conflict and energy-price pressures. A separate Cleveland Fed yield-curve model was even stronger, showing a 3.5% GDP growth prediction in April. Taken together, that points to a baseline of continued positive growth, but not one so strong that a June GDPNow reading above 4% should be the modal expectation. (atlantafed.org)
The most useful base-rate evidence is the recent history of same-stage GDPNow readings—roughly 50 days before the BEA advance release. Recent examples are 3.8% for Q2 2025 on June 9, 2025, 3.1% for Q3 2025 on September 10, 2025, and 2.7% for Q1 2026 on March 12, 2026. That crude average is about 3.2%, but I do not want to anchor too hard on it. The Q2 2025 reading was later revised down within GDPNow itself to 3.5% on June 17 and 3.4% on June 18, while the Q1 2026 same-stage reading of 2.7% on March 12 later slid to 1.2% by April 21. So recent same-stage nowcasts have had a mild upward bias relative to where the model later settled, and that pushes me to shade below the raw 3.2% base rate. (atlantafed.org)
My synthesis is therefore: (1) the resolving estimate is very likely the June 9, 2026 GDPNow publication; (2) the macro backdrop supports continued expansion rather than contraction; (3) same-stage GDPNow history suggests something in the upper-2s to low-3s is most natural; but (4) current Q1 softness and energy/trade uncertainty justify a discount from the recent 3.2% same-stage average. I therefore center the distribution at about 2.73% SAAR, with a moderate right tail because GDPNow can still jump on trade and inventory arithmetic, and a small left tail for the possibility that April/early-May demand data disappoint more than expected. That is why my distribution is concentrated around the 2.5%–3.1% region, but still leaves nontrivial probability above 4% and a very small probability below 0%. (atlantafed.org)
I expect the resolving publication date to be June 9, 2026. The Atlanta Fed GDPNow release-dates page currently lists Q2 2026 updates on April 30, May 1, May 5, May 7, May 8, May 14, May 21, May 28, June 1, and June 9, with the next listed update on June 16. Because this market resolves at June 15, 2026 23:59 UTC, the June 9 post is overwhelmingly likely to be the relevant one. GDPNow also says nowcasts generally begin right after the prior quarter’s advance GDP release and are updated six or seven times per month; BEA’s official schedule puts the advance estimate for Q1 2026 on April 30, 2026, matching the Atlanta Fed’s listed initial Q2 nowcast date. (atlantafed.org)
Recent Q2 early- to mid-June readings give the main base rate. Official Atlanta Fed pages show Q2 GDPNow at 0.9 percent on June 8, 2022; 2.2 percent on June 8, 2023; 2.6 percent on June 6, 2024 and 3.1 percent on June 18, 2024; and 3.8 percent on June 9, 2025. That is a wide range, but the center of mass is still in roughly the low- to mid-2s once both the weak 2022 outlier and the strong 2025 reading are kept in view. (atlantafed.org)
The live macro backdrop looks softer than 2025 but still expansionary. Atlanta Fed GDPNow is 1.2 percent for Q1 2026 as of April 21, 2026. The New York Fed Staff Nowcast headline on April 24, 2026 is 2.4 percent for 2026:Q1, and the Philadelphia Fed Q1 2026 SPF reports 2.6 percent growth this quarter and 2.5 percent annual-average growth for 2026. March 2026 payrolls rose 178,000 and unemployment was 4.3 percent, but BLS also says payroll employment had changed little on net over the prior 12 months and federal government employment continued to decline. February 2026 retail sales rose 0.6 percent month over month, and BEA reported February PCE up 0.5 percent month over month. Inflation also re-firmed in March, with CPI up 0.9 percent month over month and 3.3 percent year over year and PPI up 4.0 percent year over year. I read that mix as continued expansion with some real-income and public-sector headwinds, which argues against simply extrapolating the June 9, 2025 GDPNow reading of 3.8 percent into 2026. (atlantafed.org)
GDPNow notes that even its final-quarter nowcasts have an average absolute error of 0.77 percentage points and an RMSE of 1.17 percentage points against BEA’s initial GDP release; by inference, a June 9 nowcast should still be treated as meaningfully uncertain. My best single-number guess is 2.4 percent, published on June 9, 2026. For the full distribution, I use a four-scenario mixture: 7 percent downside-shock risk centered slightly below zero, 23 percent soft-growth risk centered near 1.3 percent, 56 percent baseline mass centered near 2.4 to 2.5 percent, and 14 percent strong-growth mass centered in the mid-3s. That produces a mean forecast of about 2.13 percent, keeps a real but modest downside tail below 0, and leaves a small upside tail above 4. I treat annulment risk as negligible because the Atlanta Fed already has multiple Q2 2026 updates scheduled before June 15. (atlantafed.org)
The first step is the publication-date question, because resolution uses the latest GDPNow estimate published on or before June 15, 2026 23:59 UTC. The Atlanta Fed’s release schedule already lists the Q2 2026 update cadence: initial Q2 estimate on April 30, then updates on May 1, 5, 7, 8, 14, 21, 28, June 1, and June 9, with the next scheduled update only on June 16. That makes the June 9, 2026 update the overwhelmingly likely resolving publication date, and it makes annulment risk effectively negligible because a Q2 estimate is already scheduled to begin on April 30. It also matters that the June 9 cutoff comes before the June 16 and June 17 releases for housing starts, import/export prices, and retail sales, so the resolving nowcast will still be missing some important May hard data. (atlantafed.org)
For the level of the nowcast, I start with current Q2 growth baselines from forecasters that publish quarterly SAAR numbers. KPMG’s April 2026 forecast has Q2 2026 real GDP at 1.4%, RBC’s March 2026 U.S. forecast has Q2 at 1.5%, and Fannie Mae’s April 2026 forecast has Q2 at 1.7%. At a broader level, the Fed’s March 2026 SEP and the IMF’s 2026 U.S. Article IV both still point to roughly 2.4% real GDP growth for 2026 overall on a Q4/Q4 basis, which is more consistent with continued expansion than with an imminent outright recession. Taken together, those anchors suggest that a mid-June GDPNow reading in the mid-1s is a more natural base case than either a near-zero print or another 3%–4%+ surge. (kpmg.com)
Current incoming data support a positive-but-not-hot economy. The Atlanta Fed’s latest GDPNow estimate for Q1 2026 is 1.2% as of April 21. March payrolls rose by 178,000 and unemployment was 4.3%. March retail and food services sales rose 1.7% month over month nominally, which gives Q2 a decent consumption handoff, but March CPI also rose 0.9% month over month and 3.3% year over year because of the energy shock, so some of that nominal strength will be offset in real terms. ISM’s March manufacturing PMI was 52.7 and its March services PMI was 54.0; ISM’s own historical mapping associates those readings with roughly 1.8%–1.9% annualized real GDP growth. Offsetting that, University of Michigan consumer sentiment fell to 49.8 in April, signaling substantial downside risk to household demand. My inference from this mix is that hard data are still expansionary, but sentiment and energy prices argue against a very high nowcast. (atlantafed.org)
History argues for keeping the distribution fairly wide. The latest Q2 GDPNow reading on or before mid-June was 0.0% on June 15, 2022; 2.2% on June 8, 2023; 3.1% on June 7, 2024; and 3.8% on June 9, 2025. So even before the current energy shock, mid-June Q2 nowcasts have ranged from essentially stall speed to very strong growth. More generally, the Atlanta Fed emphasizes that GDPNow is a purely model-based estimate with no judgmental adjustments, and it reports a 1.17 percentage-point RMSE even for final-quarter nowcasts over 2011:Q3–2025:Q2. That combination of model rigidity and trade/inventory sensitivity is why I keep meaningful probability mass both below 1% and above 2.5%. (atlantafed.org)
My synthesis is a distribution with four regimes: a main moderate-expansion regime centered in the high-1s; a softer-growth regime around roughly 0.5%; a smaller upside regime around the high-2s in case April spending, inventories, and trade data are stronger than expected; and a small downside tail below zero in case the energy shock and weak sentiment hit real consumption faster than consensus expects. Because the June 9 resolving estimate will still precede some key mid-June releases, I think the most likely outcome is a respectable but incomplete early-quarter nowcast rather than a fully locked-in final-quarter view. My median forecast is about 1.60%, and the attached CDF centers most probability in roughly the 0.8% to 2.4% range while leaving modest tails on both sides. This final paragraph is an inference from the release schedule, current data, forecast cluster, and historical GDPNow behavior. (atlantafed.org)
As of April 25, 2026, the Atlanta Fed’s GDPNow release schedule shows the initial Q2 2026 nowcast on April 30, followed by Q2 updates on May 1, May 5, May 7, May 8, May 14, May 21, May 28, June 1, June 9, June 16, June 17, June 25, July 1, July 7, July 8, July 16, July 17, July 27, and July 28; the page also says the schedule is subject to change. That makes annulment risk negligible and makes the resolving observation overwhelmingly likely to be the June 9, 2026 GDPNow update, because the next scheduled Q2 update after June 9 is June 16, which is after the June 15, 2026 cutoff in the question. (atlantafed.org)
GDPNow is a mechanical nowcast rather than a judgmental forecast: the Atlanta Fed says there are no subjective adjustments, and it normally updates six or seven times a month after key releases such as ISM, trade, wholesale trade, retail sales, housing starts, durable goods, and personal income/outlays. The Atlanta Fed also says the average absolute error of its final GDPNow forecasts since 2011 is 0.77 percentage points, while an older back-test reported an RMSE of 1.15 percentage points just before the BEA advance estimate; since the June 9 reading is still well before the BEA’s advance Q2 GDP release on July 30, I keep meaningful uncertainty around the forecast. (atlantafed.org)
Current 2026 data point to slower-but-positive growth rather than either a clear stall or a boom. Atlanta’s Q1 2026 GDPNow estimate fell from 3.1 percent on February 20 to 1.2 percent on April 21; by April 21, the model’s Q1 nowcasts were 1.4 percent for real PCE growth, 5.6 percent for real gross private domestic investment growth, and 1.1 percent for real government expenditures growth. The New York Fed Staff Nowcast was 2.4 percent for Q1 on April 24. In the hard data, March payrolls rose 178,000 and unemployment was 4.3 percent, March retail sales rose 1.7 percent month over month and 4.0 percent year over year, and March industrial production fell 0.5 percent but still increased at a 2.4 percent annual rate in Q1 while manufacturing output rose at a 3.0 percent annual rate in Q1. (atlantafed.org)
The best base-rate anchor is recent Q2 history at the same stage of the quarter. Early-June Q2 GDPNow readings were 0.9 percent on June 7/8, 2022, 2.2 percent on June 8, 2023, 3.1 percent on June 7, 2024, and 3.8 percent on June 9, 2025. Initial Q2 readings were 1.6 percent on May 2, 2022, 1.8 percent on May 1, 2023, 3.9 percent on April 26, 2024, and 2.4 percent on April 30, 2025. So the early-June Q2 print has recently centered in the mid-2s, but it has also moved roughly a point or more from the initial print in both directions. (atlantafed.org)
My synthesis is therefore slightly below the recent early-June average, because 2026 Q1 tracking is softer than in 2024-25, but not dramatically below trend because labor and retail data remain decent. I center the June 9, 2026 GDPNow estimate for Q2 2026 at 2.3 percent SAAR, with most mass between about 1.8 percent and 2.8 percent, a smaller downside tail toward roughly 1.0 percent if the weak Q1 momentum carries into April-May data, and a right tail into the low-to-mid 3s if consumption, inventories, and trade data surprise positively. The code below implements that view as a discretized mixture over one-decimal GDPNow outcomes, which matches how GDPNow values are displayed. (atlantafed.org)
