BEA’s release schedule still shows the Q1 2026 state GDP release for June 25, 2026. The latest national signal is BEA’s second estimate for Q1 2026: real GDP grew at a 1.6% annual rate, with positive contributions from exports, investment, consumer spending, and government spending; imports increased; real final sales to private domestic purchasers grew 2.4%; and real GDI grew 0.9%. That is a positive but not especially strong national backdrop. (bea.gov)

A key modeling point is that GDP by state is not just the national expenditure headline split across the map. BEA defines GDP by state as the sum of value added from all industries in a state. That means national import drag or inventory noise does not necessarily translate one-for-one into many shrinking states, while broad industry shocks can matter a lot. BEA’s Q1 2025 state release is the clearest recent example: 39 states shrank, and the broad negatives were finance and insurance, which fell in all 50 states and D.C., agriculture, which fell in 39 states, and mining, which fell in 43 states. (bea.gov)

Recent positive quarters give a useful range. In Q1 2023 all 50 states grew. In Q1 2024, 39 states grew, implying 11 shrank. In Q4 2025, 35 states grew and Indiana and Maine were unchanged, implying 13 of the 50 states shrank. So positive national growth can still produce anything from zero to low-double-digit state contractions, especially in softer quarters. Relative to Q4 2025, Q1 2026 looks better on national composition because domestic private demand and government spending were firmer, but it is not strong enough to justify a near-zero count with high confidence. (bea.gov)

Near-term regional breadth indicators are moderately favorable. The Philadelphia Fed’s state coincident indexes for March 2026 showed 39 states up, 9 down, and 2 stable over the prior three months, and the April 2026 report improved to 47 up, 2 down, and 1 stable. But I downweight that evidence because the same coincident series looked fairly healthy in March 2025 as well—43 states up, 4 down, 3 stable—shortly before BEA reported that 39 states actually had lower real GDP in Q1 2025. So the coincident data argue against a very large count, but they are not decisive for BEA GDP breadth. (oklahoma.gov)

My synthesis is: the base case is a modest national expansion with decent breadth, pointing to roughly 5 shrinking states; the main upside risk is an unobserved broad sector hit, which could push the number into the low teens. I therefore center the forecast at about 6.3 states, with most probability mass in the 3-10 range and a meaningful but smaller right tail above 12. I also keep some spread because BEA’s national GDP estimate can still move before the third estimate—BEA says the historical average absolute second-to-third revision is 0.3 percentage point—and because this market resolves on exact SQGDP1 real-GDP levels rather than rounded percent-change displays, so a handful of borderline states can swing the final count by 1-2. (bea.gov)

BEA’s GDP by State page lists the next release for June 25, 2026, and BEA’s release schedule says that release will cover state GDP for 2026:Q1. For national context, BEA’s second estimate says real U.S. GDP grew at a 1.6% annual rate in Q1 2026, real GDI grew 0.9%, and the average of GDP and GDI grew 1.3%; exports, investment, consumer spending, and government spending all contributed positively. (bea.gov)

The historical relationship between national growth and the number of shrinking state economies is strong but noisy. In outright negative national quarters, 46 states shrank in 2022:Q1 and 40 in 2022:Q2, while in very strong national quarters no states shrank in 2023:Q1, 2023:Q3, 2023:Q4, 2024:Q4, or 2025:Q3. Intermediate positive quarters have produced small or moderate counts: 3 in 2022:Q3, 3 in 2022:Q4, 6 in 2023:Q2, 11 in 2024:Q1, 1 in 2024:Q2, 4 in 2024:Q3, 2 in 2025:Q2, and 13 in 2025:Q4. (bea.gov)

Q1 2026 sits in the middle of that history. Headline GDP growth of 1.6% is stronger than the weak 0.5% national growth in 2025:Q4, when 13 states shrank, but materially weaker than the 3%+ quarters that typically produced only 0–4 shrinking states. I also expect some rebound from the October–November 2025 federal shutdown: BEA estimated that the shutdown knocked about 1.0 percentage point off Q4 2025 national real GDP growth, and BEA says government spending turned up in Q1 2026. That should particularly reduce downside risk for some federal-heavy states relative to Q4. (bea.gov)

Against that, breadth indicators still looked soft. BLS said that in March 2026 nonfarm payroll employment increased in only 3 states and was essentially unchanged in 47 states and D.C.; over the year, payroll jobs rose in only 3 states and fell in 3 states plus D.C. The Philadelphia Fed’s state coincident index reports tell a similar story of improvement from weakness rather than a boom: in the three months to January 2026, coincident indexes rose in 37 states and fell in 13, but in the three months to April 2026 they rose in 47 states, fell in 2, and were stable in 1. I read Q1 2026 as an in-between quarter: better than the early-year soft patch, but not broad enough to justify a near-zero shrink count. (bls.gov)

My synthesis is a central estimate of 8 states with shrinking real GDP from 2025:Q4 to 2026:Q1. I put most probability mass in the 4–13 range, with thin but nontrivial tails for a broader negative result if the softness in GDI and labor-market breadth translated into unusually uneven state output. The code below encodes that judgment as a truncated normal distribution centered just under 8 with moderate dispersion. (bea.gov)

BEA’s GDP by State page says the next release covering state GDP for Q1 2026 is scheduled for June 25, 2026, and BEA’s release schedule lists it for 8:30 a.m. EDT that day. The national backdrop is modestly positive: in BEA’s second estimate, real U.S. GDP grew at a 1.6% annual rate in Q1 2026, up from 0.5% in Q4 2025, with exports, investment, consumer spending, and government spending all contributing; real final sales to private domestic purchasers rose 2.4%. (bea.gov)

Recent BEA state-GDP history is the main base rate. Among the 50 states, 11 shrank in Q1 2024 (39 rose), 1 shrank in Q2 2024 (49 rose), 4 shrank in Q3 2024 (46 rose), 0 shrank in Q4 2024 (48 rose and 2 were unchanged), 39 shrank in Q1 2025, 2 shrank in Q2 2025, 0 shrank in Q3 2025, and 13 shrank in Q4 2025 (35 rose and Indiana and Maine were unchanged). (bea.gov)

The key lesson from those releases is that national growth alone is not enough; sector concentration matters. BEA said Q1 2024 weakness in several of the most negative states was driven by agriculture as an offset to growth, and Q1 2025 weakness came from a combination of declines in finance and insurance, agriculture, mining, and wholesale trade. That is why a positive national print of 1.6% does not imply only a couple of shrinking states. Still, Q1 2026 looks broader than Q4 2025: BEA explicitly says the acceleration from Q4 to Q1 reflected upturns in government spending and exports and faster investment, partly offset by slower consumer spending. That argues for fewer shrinking states than the 13-state result in Q4 2025, though probably not as few as the 0-2 outcomes seen in stronger 2.4%-4.4% quarters. (bea.gov)

As a weak auxiliary signal, the Philadelphia Fed’s state coincident indexes improved materially through spring 2026: January 2026 showed 37 states up and 13 down over the prior three months, while April 2026 showed 47 up, 2 down, and 1 unchanged. I only use that as a mild positive nudge, not a direct mapping into BEA GDP counts, because the same coincident indexes looked strong in March 2025 even though BEA later reported 39 state GDP declines for Q1 2025. (philadelphiafed.org)

For a numerical forecast, I used a weighted recent-analog mean centered on similar BEA quarters: Q1 2024 (11), Q2 2023 (6), Q4 2025 (13), Q4 2024 (0), Q3 2024 (4), Q2 2025 (2), and Q1 2023 (0). Those weights produce an expected value of 7.95 shrinking states. I then translated that into a full discrete forecast with a beta-binomial distribution over 50 states, using mean 7.95 and concentration 30, which implies a standard deviation of about 4.15 states; the overdispersion is meant to capture correlated state shocks and the fact that the question resolves on exact real-GDP level comparisons, not rounded displayed growth rates. My central forecast is therefore 8 states, with most probability mass in roughly the 5-11 range and thinner tails into the mid-teens. (bea.gov)

BEA’s release schedule shows that the relevant publication is due on June 25, 2026, at 8:30 a.m. EDT, and BEA’s GDP by State page also lists June 25, 2026 as the next release date. My best single-number forecast is 8 states. (bea.gov)

My main macro anchor is the national Q1 2026 picture. BEA’s second estimate says real U.S. GDP grew at a 1.6% annual rate in 2026:Q1, real final sales to private domestic purchasers grew 2.4%, and real GDI grew 0.9%; exports, investment, consumer spending, and government spending all contributed positively, while imports increased. BEA’s GDP-by-state methodology defines GDP by state as output produced by labor and property located in the state and derives real state GDP from state industry value added using national chain-type price indexes. From that, I infer that the import drag in national expenditure-side GDP should not mechanically translate into a large number of shrinking state economies. In other words, Q1 2026 looks a bit better for this question than the 1.6% national headline alone might suggest. (bea.gov)

The best guide is the historical mapping from national growth to state diffusion. In 2022:Q1, national real GDP fell 1.6% and 46 states shrank. In 2025:Q1, national real GDP fell 0.5% and 39 states shrank. But in middling positive quarters the count has usually landed in single digits or the low teens: in 2023:Q2, 44 states grew, implying 6 shrank, while national GDP grew 2.1%; in 2024:Q1, 39 states grew, implying 11 shrank, while national GDP grew 1.4%; and in 2025:Q4, 35 states grew while Indiana and Maine were unchanged, implying 13 shrinking states among the 50 states even though national GDP still rose 0.5%. Those analogues make 2026:Q1 look much more like a mid-range quarter than either an almost-all-states-down quarter or an all-clear quarter. (bea.gov)

Latest state labor-market data are soft but not recessionary. BLS reported that in March 2026 unemployment rates were little changed in all 50 states and payroll employment increased in only 3 states, with the other 47 essentially unchanged. In April 2026, unemployment was stable in 45 states and payroll employment increased in 6 states, with the other 44 essentially unchanged. I treat that as a modestly reassuring secondary signal, not a decisive one, because state GDP can diverge from employment when sector-specific output swings dominate. Because this question resolves off the SQGDP1 level comparison rather than rounded percent-change displays, near-zero states can also move the final count by a state or two. (bls.gov)

So I used an overdispersed three-scenario beta-binomial mixture rather than a tight single binomial. The scenarios are: a low-diffusion case centered near 5 shrinking states, a middle case near 8.5, and a sector-shock tail near 15. The weighted mean of that mixture is 8.075 states, which is why I center the forecast around 8 while still leaving meaningful mass from roughly 4 through 12 and a thinner tail into the mid-teens.

As of June 16, 2026, this is still a forecast rather than a read of the resolving table: BEA’s release schedule shows the Q1 2026 state GDP release on June 25, 2026. The latest national data are moderately positive, not recessionary: BEA’s second estimate says real GDP grew at a 1.6 percent annual rate in Q1 2026, real final sales to private domestic purchasers grew 2.4 percent, and the contributors to growth were exports, investment, consumer spending, and government spending. (bea.gov)

The key base-rate point is that positive national growth does not guarantee every state grows, but it usually limits the damage to a minority of states. Recent BEA releases show a wide range: 39 states shrank in Q1 2025 when national GDP fell 0.5 percent; 11 states shrank in Q1 2024 even though national GDP still grew 1.4 percent; Q4 2024 had zero state contractions because 48 states grew and Idaho and South Dakota were unchanged; and Q4 2025 still had 13 declining states among the 50 states because only 35 states grew while Indiana and Maine were unchanged and the District of Columbia also declined. (bea.gov)

Q1 2026’s composition looks better for state breadth than Q4 2025’s. In Q4 2025, government spending and exports were drags, and BEA said government value added fell 7.8 percent nationally; in Q1 2026, government spending and exports turned up, while domestic final sales stayed solid at 2.4 percent. That should make a repeat of the late-2025 state-level weakness less likely, especially for government- and trade-sensitive states. (bea.gov)

A useful cross-check is the Philadelphia Fed’s state coincident-index release for April 2026. Over the prior three months, the coincident indexes increased in 47 states, decreased in 2, and were stable in 1; the U.S. coincident index rose 0.5 percent over the same span. This is not the same series as BEA state GDP, but the coincident index is built from state employment, hours, unemployment, and real income variables, and its long-run trend is set to state GDP, so it is a relevant breadth signal for activity around the end of Q1 and start of Q2. (philadelphiafed.org)

I do not want to push the estimate too low, though. First quarters can be noisier than other quarters, BEA revised Q1 2026 national GDP down from 2.0 percent to 1.6 percent mainly because investment and consumer spending were weaker than first estimated, and BEA’s regional program relies on the income approach to measure GDP by state, so national expenditure-side GDP does not map mechanically into the state count. (bea.gov)

My synthesis is a center of about 7 shrinking states. I encode that with a beta-binomial distribution over 50 states, using moderate overdispersion to reflect common national and sector shocks. That puts the highest probability on outcomes in the mid-single digits through around 10, leaves meaningful probability on both 0-2 and low-teens outcomes, and very little on extremes. Because resolution uses exact real-GDP levels rather than rounded percent changes, I leave noticeable mass on adjacent integers near the center.

46 states (+DC) saw their economies grow but only 3 saw their economies shrink as Delaware has recorded a ±0.0.

Looking in more details at the tables, Delaware also grew, just not very much:

How many U.S. state economies shrank in Q1 2026?

• My most likely prediction for the number of U.S. state economies that shrank in Q1 2026 is 6.50, with a 50% chance of falling between 4.50 and 10.50.
• National real GDP grew at a 1.6% annualized rate in Q1 2026, an acceleration from the 0.5% growth in Q4 2025, suggesting a likely decrease in the number of contracting states from the 13 recorded in the previous quarter.
• Economic performance was highly bifurcated, with a booming energy sector (+35.1% return) likely supporting growth in resource-rich states while a declining tech sector (-7.8% return) and falling residential investment (-8.0%) created headwinds for others.
• Major tech-dependent states like California and Washington reported significant corporate layoffs and employment losses in early 2026, increasing the probability that they are among the shrinking economies.
• Historical patterns indicate that even during non-recessionary expansion, typically 3 to 12 states contract due to localized industry shifts or sectoral corrections.
• The Bureau of Economic Analysis is scheduled to release the official state-level data for Q1 2026 on June 25, 2026.

Key figures

Historical context

• In the previous quarter (Q4 2025), national real GDP growth was 0.5% annualized, and 13 states experienced a contraction.
• Historically, during periods of national economic expansion (1.0% to 2.0% growth), it is typical for 3 to 12 states to post negative quarterly growth due to local industry volatility.
• In 2025, the U.S. saw significant quarterly volatility, with Q1 2025 showing a national contraction of -0.6% before rebounding to 4.4% in Q3 2025.
• State-level GDP is significantly more volatile than national GDP; for example, North Dakota and energy-rich states often see swings of +/- 3% based purely on commodity prices.
• As of Q4 2025, Indiana and Maine were stagnant (0.0% growth), suggesting they are high-probability candidates for contraction if local conditions worsened slightly in Q1 2026.

Tailwinds

• Strong national growth of 1.6% provides a rising tide that typically prevents widespread state-level contraction.
• A 35.1% surge in the energy sector likely ensured robust growth for states like Texas, North Dakota, and Alaska.
• Federal government spending grew at a 9.3% annual rate in Q1 2026, supporting economies in states with high federal footprints.
• Services spending rose by 2.4% nationally, benefiting states with large tourism, healthcare, or financial services sectors.

Headwinds

• A 7.8% decline in the technology sector (XLK) during Q1 2026 likely impacted tech-heavy state economies like California and Washington.
• National residential investment fell at an 8% annual pace, creating a drag on states with large construction and real estate sectors.
• Consumer spending on goods dropped by 0.1%, which may have pushed states reliant on manufacturing or retail distribution into contraction.
• Major corporate layoffs were recorded in early 2026, including over 175,000 positions in California and 8,000 in Washington.

Detailed reasoning

• The forecast is anchored in the transition from Q4 2025 to Q1 2026. In Q4 2025, the national economy grew at a very weak 0.5% annualized rate, which resulted in 13 states experiencing a contraction in real GDP. For Q1 2026, the national growth rate accelerated to 1.6% (according to the BEA second estimate).
• Historically, an acceleration in national GDP reduces the number of contracting states. A 1.1 percentage point increase in annualized growth typically shifts the state-level distribution toward the positive. However, Q1 2026 was characterized by extreme sectoral bifurcation rather than uniform growth.
• The energy sector (XLE) provided a massive tailwind, with a 35.1% total return for the quarter, likely ensuring growth in states like Texas, North Dakota, and Alaska. Conversely, the technology sector (XLK) declined by 7.8%, and national residential investment (housing) fell at an 8% annual pace.
• These specific headwinds are weighted heavily in my reasoning. Because housing and tech are significant components of many state economies, it is unlikely the number of contracting states will drop to zero. Instead, I expect the “K-shaped” nature of the recovery to leave several states behind.
• I modeled the prediction using a primary expectation that 4 to 10 states contracted (representing 75% of the probability mass), centered at 6.5. This accounts for the improved national backdrop while acknowledging that structural drags in housing and tech will prevent a unanimous 50-state expansion.
• A secondary scenario (25% weight) considers the possibility of a higher count (near 10-14 states) if the consumer goods slowdown (-0.1% spending) and corporate layoffs (e.g., 175,000 in California) were more geographically concentrated than initially estimated.
• The resulting 50% HDI of 4.50 to 10.50 states reflects a high-confidence range that the economy remains in an expansionary phase but is failing to lift all boats due to high costs and shifting sector fortunes.

Key uncertainties

• The “third estimate” for national GDP (to be released June 25) could further revise the 1.6% growth figure, shifting the baseline for all states.
• The exact geographic distribution of the 8% drop in residential investment is unknown; if concentrated in a few states, the total count of shrinking economies may remain low.
• “Real GDP” level changes in the SQGDP1 table can be negative even if rounded growth rates are 0.0%, adding a layer of measurement sensitivity.
• Potential revisions to Q4 2025 levels could change the comparison baseline for Q1 2026 results.

Conclusion

• My analysis predicts a most likely outcome of 6.50 states, indicating that while the national economy grew, sector-specific challenges (housing and tech) likely pushed several regional economies into a mild quarterly contraction.
• Decision-makers should focus on the June 25, 2026, BEA release, specifically comparing the real GDP levels (millions of chained 2017 dollars) for 2026:Q1 against 2025:Q4 to identify underperforming regions.
• The high dispersion between sectors (energy vs. technology) suggests that “national growth” may mask significant local economic stress in states reliant on interest-rate-sensitive industries or tech manufacturing.

Question: how many U.S. states had real GDP levels lower in 2026:Q1 than in 2025:Q4 per the BEA state GDP file? The teams use BEA’s unreleased Q1 state GDP (SQGDP1 LineCode 1) as the controlling source on June 25 and anchor forecasts to the national Q1 signal — real GDP +1.6% SAAR (GDI +0.9%, GDP/GDI +1.3%) — plus historical Q1 breadth patterns. Historically, positive but modest national Q1 growth has still produced low‑double‑digit state declines (e.g., Q4 2025 = 13 states down; 2024:Q1 ≈ 11), and Philly Fed coincident indexes and BLS state labor data show limited breadth weakness (roughly 8–9 states down in early‑Q1 indicators), arguing against a broad 30+ state collapse. Forecasters therefore center their distributions in the roughly 7–12 state range (most centering ~8–12) with a modest right tail for sector‑driven or tariff/energy/federal‑spending shocks, and little mass above the mid‑20s absent a national contraction. All teams agree on using the BEA level comparison (Q1 vs Q4 in the controlling SQGDP1 file), and they note caveats about BEA revisions and industry‑specific patterns (finance, agriculture, mining, construction, tariffs, AI/data‑center projects) that could shift the count.

Forecast Reasoning

We are forecasting the count of states whose BEA SQGDP1 real GDP level in 2026:Q1 is below its 2025:Q4 level. As of 2026-06-16 the Q1 2026 state GDP data are not yet released (scheduled for 2026-06-25), so this is an ex-ante distribution.

Key drivers and evidence from the analysts:

1. National macro backdrop: Q1 2026 U.S. real GDP grew about +1.6% SAAR (second estimate, cited by Forecaster 3). With modest positive national growth, the typical outcome is a low-double-digit number of state declines (dispersion persists due to sector mix and measurement noise).
2. Recent analog quarters (from BEA writeups, used by Forecasters 2 and 3):

• 2024:Q1 (national growth around +1.3% to +1.4%) reportedly had ~11 states with declining real GDP on BEA’s sign-count summaries.
• 2025:Q4 (national +0.5% SAAR) reportedly had 35 states increasing, 2 unchanged on rounded percent-change, implying ~13 declining (Forecaster 3); some analysts interpreted this as closer to ~15, consistent with small differences between rounded percent-change and strict level comparisons. These analogs support a central estimate around 9–12 declines for Q1 2026, likely somewhat fewer than Q4 2025 given stronger national growth.

3. Additional indicator: Forecaster 4 cites Philadelphia Fed state coincident indexes showing 9 states declining over the three months ending March 2026 (a Q1-aligned signal). This is suggestive but not determinative because (a) it is not the BEA GDP measure, and (b) GDP includes volatile sectors (notably agriculture/mining) not fully captured by the index. I treat it as modest support for a ~10-ish central value, not as a reason to tighten uncertainty.

Synthesis and calibration:

• I weight Forecasters 2 and 3 more heavily for citing multiple BEA quarter sign-count analogs and keeping a moderate dispersion.
• I down-weight Forecaster 1’s higher median/upper tail because it leans on speculative policy shocks (“tariff environment”) without clear evidence and appears wider than typical dispersion when national GDP is +1.6% SAAR.
• I keep some extra upper-tail mass because the resolution uses strict level comparisons in SQGDP1; states shown as 0.0% in rounded displays can still be slightly negative in levels, pushing the decline count up by a small number.

Result: median 11 shrinking states, with most mass roughly in the 6–16 range, and a cautious but not extreme upper tail into the low 20s.

An amateur forecast would likely (a) map positive national GDP growth to “almost no states shrink,” or (b) anchor mechanically on the previous quarter’s shrink count without adjusting for Q1’s stronger national growth and the level-vs-rounded-sign nuance in the resolution criteria. My forecast instead triangulates across multiple recent BEA analog quarters at similar national growth rates, explicitly accounts for the SQGDP1 level-comparison rule (which can modestly raise the count versus rounded sign summaries), and avoids overconfident tightening based on non-BEA proxies (e.g., coincident indexes). I’m moderately confident this improves calibration, though quarter-to-quarter state dispersion remains inherently noisy.

Forecast rationale (numeric):

— Iteration 1 — The forecasts converge on a teens-level count of shrinking state economies in Q1 2026, roughly 13–15 states, with meaningful uncertainty around that center.

Main reasoning patterns

• Moderate national growth as the anchor:
  Q1 2026 U.S. real GDP was positive but not strong, which generally implies only a subset of states would contract rather than a broad nationwide decline.

• Historical comparison to similar growth quarters:
  Prior quarters with comparable national growth tended to produce around 10–12 shrinking states, providing a baseline for the estimate.

• Recent state-level dispersion matters:
  The previous quarter already saw an elevated number of states contracting despite national expansion, suggesting state economies were behaving unevenly, which supports a count above the historical baseline.

• Sector-specific weakness could raise the total:
  Inventory effects and possible weakness in manufacturing and wholesale-linked states were seen as factors that could push the number higher.

• BEA measurement details add uncertainty:
  The final count depends on state-level level changes, not just headline growth rates, so revisions and the exact BEA methodology could shift the result by a few states.

Areas of consensus

• The number is not likely to be extremely low if national growth remains positive.
• A mid-teens outcome is the most plausible central estimate.
• There is substantial uncertainty, with wider tails than usual due to revisions and uneven state performance.

Main differences in emphasis

• Some reasoning leans slightly lower by stressing historical analogs and moderate national growth.
• Others lean slightly higher by emphasizing recent elevated dispersion, sectoral weakness, and the possibility that the BEA level-based measure captures more contractions.

Bottom line

The overall judgment is that about 13 to 15 U.S. state economies likely shrank in Q1 2026, with plausible outcomes somewhat below or above that range depending on revisions and state-sector dispersion.

— Iteration 2 — The forecasts largely anchor on two signals: the prior quarter’s state pattern and the Q1 2026 national economy. In Q4 2025, 13 states shrank, and Q1 2026 national GDP was still positive but only moderately so, suggesting that some states likely remained in contraction even if the economy was expanding overall.

Overall, the reasoning converges on a low-to-mid teens estimate for the number of shrinking state economies, with a rough center around about 13–15 states. One view places the count somewhat lower, around 9, arguing that improving national indicators should reduce the number of contractions from Q4 2025. The others lean slightly higher, emphasizing that a modest national growth rate still typically leaves a substantial minority of states negative, especially when regional and sector-specific weakness is unevenly distributed.

Common themes across the rationales:

• Benchmarking against Q4 2025: 13 shrinking states is the key reference point.
• National growth is positive but not strong enough to eliminate state-level contractions.
• State economies are uneven, so large-state strength can mask weakness in smaller or sector-sensitive states.
• Uncertainty is meaningful, due to geographic dispersion, sector shocks, and noise in advance state estimates.

In short, the collective logic points to roughly a dozen-plus states shrinking in Q1 2026, with disagreement mainly over whether the count drifted down slightly from Q4 or edged up modestly.

— Iteration 3 — The forecasts converge on a low-to-mid teens estimate for the number of U.S. states whose economies shrank in Q1 2026, with most reasoning centered on a few common themes:

Key reasoning patterns

• Benchmarking to recent history: Several forecasts anchor on Q4 2025, when about 13 states contracted, and treat that as a useful reference point for Q1 2026.
• National growth was positive but modest: Q1 2026 U.S. real GDP growth of about 1.6% SAAR is seen as supportive of some state-level expansion, but not strong enough to prevent contractions in a substantial minority of states.
• State-level dispersion matters: The models assume that even with positive national growth, individual states can still diverge meaningfully due to local industry mix, regional shocks, and normal volatility.
• Historical contraction share: One rationale explicitly uses past patterns suggesting roughly 20–30% of states may contract when national growth is modest.
• Allowance for measurement and revision noise: The forecasts include uncertainty for BEA allocation quirks, revisions, and the possibility that headline national GDP may understate or overstate underlying regional weakness.

Areas of consensus

• The estimates cluster tightly around 12 to 16 shrinking states.
• None of the rationales expect either very broad recession-like weakness or near-universal growth.
• All models treat the outcome as moderately uncertain, with a skew toward somewhat more states shrinking if weakness is concentrated regionally.

Main differences in emphasis

• More conservative estimates lean on historical analogs and statistical dispersion models, putting the median around 12–13.
• Higher estimates give more weight to possible hidden regional weakness, tariff or policy effects, and “unknown unknowns,” pushing the median toward 15–16.
• The uncertainty ranges differ mainly in how much weight is given to extreme outcomes, but the central tendency remains similar.

Overall synthesis

Taken together, the forecasts suggest that Q1 2026 likely saw contraction in a modest share of states, roughly in the low-to-mid teens, driven by positive but weak national growth, normal cross-state variation, and the possibility of localized economic softness.

Macroeconomic Baseline Forecasters ground their reasoning in the Bureau of Economic Analysis (BEA) second estimate for Q1 2026, which reported a modest, positive national real GDP growth rate. While this marks a notable acceleration from the sluggishness of Q4 2025, historical base rates demonstrate that this specific tier of mild national expansion is rarely broad-based. Instead, it typically masks a moderate cluster of state-level economic contractions.

Proxy Indicators and “The Floor” A primary anchor across all rationales is the Philadelphia Fed’s State Coincident Index (SCI), which reported that exactly nine states experienced negative economic momentum in the first quarter. Because the SCI relies heavily on stable labor metrics, official state GDP—which incorporates highly volatile sectors like agriculture, mining, and corporate profits—is structurally “noisier.” Consequently, forecasters agree that this nine-state figure serves as a highly reliable floor, with the actual GDP contraction count expected to sit slightly higher.

Regional Shocks and Sectoral Drags Despite national economic stability, forecasters point to several idiosyncratic, localized shocks that place significant downward pressure on specific states:

• Severe Weather: “Winter Storm Fern” caused massive property damage, power outages, and business interruptions across the Southern Plains, Midwest, and Eastern Seaboard.
• Labor Disruptions: Large-scale labor actions, particularly the Kaiser Permanente healthcare strikes and regional meatpacking strikes, severely suppressed service and manufacturing output in states like California, Hawaii, Oregon, and Colorado.
• Sector-Specific Downturns: A notable pullback in real estate and construction dragged down the Sun Belt, while falling rig counts and lower natural gas extraction weighed heavily on commodity-reliant states like Wyoming, New Mexico, and North Dakota.
• Government Shutdown Spillovers: The lingering economic hangover from the late-2025 federal funding lapse disproportionately impacted federal-heavy economies like Maryland and Virginia.

Methodological and Statistical Factors Finally, forecasters highlight two statistical mechanisms that will likely push borderline states into negative territory. First, the BEA’s “advance estimates” rely on smaller data samples and frequently exhibit “residual seasonality,” a statistical quirk that historically depresses initial first-quarter growth prints. Second, strong mean-reverting base effects are at play; several states that experienced anomalous, one-off GDP spikes in Q4 2025 (due to exceptional agricultural yields or legal settlements) are mathematically positioned to contract as their output normalizes.

Research Summary

The research found that U.S. real GDP grew 1.6% (annualized) in Q1 2026 (revised down from an initial 2.0%), roughly 0.4% quarter-over-quarter, and that BEA state-level GDP data for Q1 2026 had not been released as of June 16, 2026 (the BEA was scheduled to publish Q1 2026 state GDP on June 25, 2026). It also noted sectoral and macro context for Q1 2026: upward contributions from exports and government spending, downward revisions from weaker inventory investment and consumer spending, persistent PCE inflation (~4.5% y/y), and slower corporate profit growth.

For historical reference, the research reported that in Q1 2025 real GDP decreased in 39 of 50 states, while in Q4 2025 real GDP increased in 35 states (meaning 15 states declined). It recorded that there were no specific prediction-market contracts found for the exact question, that Polymarket/Kalshi track broader recession probabilities, and that analysts/TD Economics provided modest annual state-growth projections for 2026. The research emphasized the BEA state-GDP table (Q1 2026 vs Q4 2025) as the controlling source for answering the question once released.

Frontier Views (4/4)

frontier_1 — Modal: 6-13 (52.0%)

National real GDP grew at a 1. 6% annualized rate in Q1 2026, an improvement from Q4 2025 (0. 5% annualized).

frontier_2 — Modal: 6-13 (47.0%)

National Q1 2026 real GDP grew ~1. 6% annualized (~0. 4% q/q).

frontier_3 — Modal: 6-13 (45.0%)

U. S. national real GDP for Q1 2026 was reported to have grown at a moderate annualized rate of 1.

frontier_4 — Modal: 0-6 (68.0%)

National Q1 2026 real GDP grew +1. 6% annualized. In expanding quarters, BEA state data historically show only 3-12 states contracting (mode 4-9).

Model’s Answer: Looking at this question, I need to forecast how many of the 50 U.S. states will show real GDP declines from Q4 2025 to Q1 2026, based on BEA data to be released June 25, 2026.

Key Information Analysis

National Context:

• Q1 2026 real GDP: +1.6% annualized (second estimate, revised down from 2.0% advance)
• Q4 2025 real GDP: +0.5% annualized (comparatively weaker)
• The labor market remains relatively strong (4.3% unemployment in May 2026)
• Inflation elevated at 4.2% suggests continued restrictive monetary policy

Historical Benchmarks (Critical for calibration):

• Q4 2025: Real GDP increased in 35 states, unchanged in 2 states → 13 states shrank
• Q1 2025: Real GDP decreased in 39 states (an unusually weak quarter)

Top-Down Reasoning: Since Q1 2026 (+1.6% SAAR) was stronger than Q4 2025 (+0.5% SAAR), I would expect fewer states to shrink in Q1 2026 than the 13 that shrank in Q4 2025. However, several crosscurrents exist:

• Trade war concerns and tariff uncertainty could disproportionately affect manufacturing/agricultural states
• Strong tech capex should support tech-heavy states
• Interest rate sensitivity affects construction/real estate-concentrated states

Critical Assumptions to Stress-Test:

1. The relationship between national GDP growth and state-level contraction count is roughly linear - If this fails (non-linear relationship), my estimate could be off by 5+ states. Probability of failure: ~15%
2. Q1 2026 sectoral composition is roughly similar to Q4 2025 - If unusual sectoral shifts occurred, more/fewer states could contract. Probability: ~20%
3. No major data revisions between now and release - This is unlikely to matter significantly. Probability: ~5%

Low Outcome Scenario (3-6 states shrink): Strong tech investment, broad-based growth across regions, and Q1 rebound momentum minimizes contractions. Likelihood: ~15%

High Outcome Scenario (18-25+ states shrink): Trade war impacts hit manufacturing/export states harder than expected, or compositional effects show weakness concentrated in many states despite positive national growth. Likelihood: ~10%

Distribution Construction

Given Q4 2025 saw 13 states shrink with +0.5% national growth, and Q1 2026 had +1.6% (stronger), my central estimate is approximately 8-11 states shrinking. I’m placing my median around 9-10, with meaningful right-tail risk given historical volatility (Q1 2025 saw 39 states shrink).

State real GDP is a level-by-level quarterly accounting anchored to national growth and uneven industry composition.

Concentration in finance, agriculture, mining, and a few services sectors creates persistent cross-state sensitivity to common shocks.

Modest national growth in Q1, driven by exports, investment, consumption, and government, lifts aggregate output but leaves many states near flat.

Employment and coincident indicators have been broadly steady, reducing the chance of widespread synchronized expansions.

Q1 seasonality and common-industry noise historically push more states into small level declines, so the distribution centers near sixteen states down.

A government-spending rebound and stronger trade tilt the outcome toward fewer down states, while concentrated sector weakness or inventory swings push it higher.

Several states are within rounding and level-noise bounds, so small revisions or base-period adjustments can flip their status.

The principal uncertainties are upcoming quarter-to-quarter level revisions and industry-by-industry adjustments that can move the count by a handful or more.

Forecast: 10.7343 states

• The U.S. economy as a whole is expected to have grown in Q1 2026, which usually keeps the number of contracting states in the low-to-mid teens (not anywhere near the extreme).
• The best nearby benchmark is Q1 2024, when national growth was similar and 11 states contracted; Q4 2025 was weaker and had 15 contracting states, bracketing this estimate.
• The main reason the count might be higher than Q1 2024 is sector mismatch: some areas (notably finance/insurance and possibly agriculture) could underperform even while the overall economy grows.
• Energy-price disruption tied to Iran/Hormuz likely shifts results across states unevenly—helping energy producers but weighing on others—creating a higher spread.
• The biggest upside risk for this question is a “broad but hidden” sector drag (especially if weakness clusters across many states again).
