Forecast: Probability distribution:
Key timing anchor is CBP/trade guidance that IEEPA refunds are generally expected to be issued via ACH about 60–90 days after CAPE Declaration acceptance. Since CAPE opened 2026-04-20, the earliest plausible receipts cluster around late June (roughly 60+ days after very fast acceptance for a “best prepared” importer).
However, this market resolves on the first publicly confirmed importer receipt date, and in practice that adds uncertainty: (i) acceptance may not be immediate even for early filers, (ii) the first receipts could occur for firms that do not quickly publicize the exact receipt date, and (iii) if confirmation arrives but does not state an earlier receipt date, the resolution date effectively becomes the publication date, pushing the realized resolution later than the earliest possible payments.
Synthesizing the analysts: I discount the very-early-May tail as inconsistent with the stated 60–90 day issuance guidance, and I also avoid putting mass right at the open upper bound (and recognize a non-trivial chance that no qualifying confirmation is published before the 2026-08-12 cutoff). The resulting distribution concentrates in late June through July, with a 5–10% tail “above upper bound” represented by percentiles after 2026-08-12.
An amateur forecast is likely to (a) anchor mechanically on “60 days after portal launch” without separating acceptance vs issuance vs confirmed receipt, and/or (b) ignore the resolution’s strict requirement for an importer-side public confirmation published before the deadline, which creates real probability of an above-upper-bound outcome even if CBP processes refunds internally. My forecast explicitly models these frictions and expresses the open-upper tail by placing upper percentiles past 2026-08-12, improving calibration under the stated resolution rules.

The research outlines the timeline and mechanisms surrounding the refund process for IEEPA tariffs following the U.S. Supreme Court’s ruling on February 20, 2026, which invalidated these tariffs. The Court of International Trade subsequently mandated the Customs and Border Protection (CBP) to initiate refunds, starting with unliquidated entries and expanding to include finally liquidated entries. CBP launched the CAPE portal on April 20, 2026, to facilitate refund requests, with an official estimate indicating that refunds will be issued within 60 to 90 days after the acceptance of a CAPE Declaration. This suggests that the earliest refunds could be expected between mid-June and mid-July 2026.
Several factors could influence the timing of these refunds, including judicial oversight, interest accrual on the owed amounts, and the simplicity of claims submitted. Conversely, potential delays may arise from technical issues with the portal, strict data accuracy requirements, political opposition, and low enrollment in the ACH system necessary for electronic payments. The research also notes that while no specific prediction markets exist for the timing of the first refund payment, a secondary market has emerged where financial entities are purchasing refund claims from importers in need of immediate liquidity.
Sources used in the research include:
On February 20, 2026, the U.S. Supreme Court ruled 6-3 in Learning Resources, Inc. v. Trump that IEEPA does not authorize tariffs, invalidating all IEEPA tariffs [22]. The Court of International Trade (CIT) subsequently ordered CBP to begin refunds, with a March 4 order covering unliquidated entries and a March 27 expansion to include finally liquidated entries [22].
On April 20, 2026, CBP launched the CAPE (Consolidated Administration and Processing of Entries) portal within the ACE system to process refund requests [1][7][21]. As of today (April 23, 2026), the portal has been live for just 3 days.
CBP’s Official Estimate: Refunds will be issued within 60 to 90 days after acceptance of a CAPE Declaration [4][5][7][8][13][14][16][21]. This would place the earliest refunds approximately mid-June to mid-July 2026 assuming Day 1 acceptances were processed.
Phase 1 Scope: Covers ~63% of all IEEPA entries — unliquidated entries and those within 80 days of liquidation — representing approximately $127 billion of the total $166 billion [1][7][16][22].
Refund Mechanism: All refunds are issued exclusively via ACH (Automated Clearing House) electronic payments. No paper checks. Importers must have ACH banking details pre-registered in their ACE importer subaccount [12][13][16][21].
Judicial Pressure: The CIT is actively overseeing the process and requiring periodic progress reports from CBP [16]. Judge Richard Eaton has been aggressive in ordering full refunds [14].
Interest Accrual: The government is accruing approximately $22 million per day in interest on the $166 billion owed (7% for individuals, 6% for corporations, compounded daily) [13][25]. This creates strong fiscal incentive for the Treasury to process refunds quickly.
Large Volume of Simple Claims: Some importers with very clean, straightforward entries (no protests, no AD/CVD complications, no reconciliation flags) could theoretically be processed faster than the 60-90 day window.
High Registration: As of April 9, over 56,000 importers had registered, covering 82% of eligible entries ($127 billion) [4][5][7]. Major shippers like UPS, FedEx, and DHL filed claims on Day 1 [24][29].
Technical Glitches: The portal had a rocky launch — importers reported “high volume” errors and system crashes. Learning Resources CEO Rick Woldenberg described the system as “blinky” and “overwhelmed” [4][5].
Data Accuracy Requirements: Submissions cannot be modified after acceptance. Errors result in rejection of the entire file, requiring resubmission [1][10][17]. This could create cycles of rejection and resubmission.
Political Headwinds: President Trump called the ruling “a shame” and suggested companies that don’t seek refunds are “brilliant” [25][29]. The White House has indicated it may use alternative authorities to reduce refund amounts [8][20].
Compliance Reviews: CBP warned that filing requests may trigger investigations into entries, potentially causing delays or exposing importers to fines [12][13].
Low ACH Enrollment: As of early March, fewer than 10% of the 330,000 eligible importers had completed electronic refund setup [16][22]. Without ACH setup, refunds will be rejected.
Scale of Operations: 53 million entries across 330,000 importers representing $166 billion is unprecedented for CBP [7][16][22].
No specific prediction markets were found on the exact question of when the first IEEPA tariff refund payment will be received by an importer. General prediction markets on Kalshi and Polymarket have covered the broader IEEPA tariff situation (e.g., whether the Supreme Court would strike down tariffs), but not this specific operational milestone [23]. The absence of a liquid prediction market on this specific question means there’s no market-based probability to reference.
A notable development: a secondary market has emerged where hedge funds and financial firms are buying tariff refund claims at a discount from importers who need immediate liquidity or lack resources to manage the process [20]. This suggests sophisticated financial actors believe refunds will ultimately be paid but may take significant time.
| Scenario | Estimated First Receipt Date | Rationale |
|---|---|---|
| Optimistic | Early-to-mid June 2026 (~45-50 days) | CBP processes simplest claims faster than 60-day estimate; judicial pressure accelerates timeline |
| Base Case | Late June to mid-July 2026 (~60-90 days) | Aligns with CBP’s official 60-90 day guidance |
| Pessimistic | August-October 2026 (~100-150+ days) | Technical difficulties, political obstruction, compliance reviews delay even the first payments |
| Extreme Pessimistic | After August 12, 2026 (resolves “above upper bound”) | Administration finds legal or bureaucratic mechanisms to delay all payments beyond the resolution deadline |
The most critical data point is CBP’s consistent 60-to-90 day estimate from claim acceptance, which has been cited across virtually all sources [1][4][5][7][8][10][13][14][16][21][25]. If the first clean claims were accepted on April 20 (Day 1), the 60-day mark falls around June 19, 2026 and the 90-day mark around July 19, 2026.
However, the question requires not just CBP processing but confirmed receipt by an importer via a credible public source. This adds additional lag — an importer must receive the ACH payment, and then a news outlet, trade publication, or the importer itself must publicly confirm it. Given the enormous public interest in this story ($166 billion, 330,000 importers, major retailers expecting billions), media coverage of the first refund receipt is likely to be swift once it happens.
The strongest anchoring points are:
The resolution window (before August 12, 2026) gives approximately 110 days from the portal launch, which encompasses the full 60-90 day CBP estimate. The question of whether it resolves within range likely hinges on whether the administration cooperates with the process or finds mechanisms to delay.
The critic raises several compelling points that warrant adjustment to my forecast. Let me address them systematically.
Two-Stage Process Timing: The critic correctly identifies that the 60-90 day estimate is from acceptance, not submission. With the CAPE portal already showing “high volume” errors and being described as “blinky,” validation could take 1-3 weeks for early filers. This pushes realistic first receipts out by at least a week.
Confirmation Lag Underestimated: My 1-3 day estimate was optimistic. Trump’s explicit threats to “remember” companies creates a chilling effect on public announcements. Even companies that receive refunds may delay or decline to publicize. 5-10 days is more realistic for the first confirmed receipt.
P0.1 Too Aggressive: May 28 (38 days) was unrealistic given documented technical issues and the validation-then-processing sequence. Even an expedited showcase payment would need ~45 days minimum.
Above Upper Bound Probability: Political headwinds (Trump’s statements, Bessent’s “mess” warning, potential alternative authorities) justify a higher probability than my implicit ~18%. Moving this to ~23-25% is appropriate.
Judicial Pressure Is Real: CIT Judge Eaton has been aggressive, requiring progress reports. This creates genuine accountability that could accelerate at least some “showcase” payments to demonstrate compliance.
Fiscal Incentive Matters: $22M/day in interest accrual isn’t trivial over 90+ days. Treasury career officials may push back on extreme delays regardless of political preferences.
Major Importers Filed Day 1: UPS, FedEx, DHL, and Learning Resources (the plaintiff!) filed immediately. These entities have sophisticated ACH setup, clean entries, and strong incentive to publicize. At least one will likely confirm receipt relatively quickly.
International Companies May Confirm First: The critic’s point about ebm-papst and other foreign companies being less susceptible to political pressure is astute. They may publicize receipt more readily.
Secondary Market as Signal: Hedge funds buying claims have every incentive to publicize successful receipts to validate their investment thesis.
Resolution Mechanics: Even if a refund is received August 10, failure to confirm publicly by August 12 00:00 UTC means “above upper bound.” This confirmation lag risk is underweighted in my original forecast.
Timeline Reconstruction:
I’m shifting my distribution to the right, particularly:
Updated prediction:
Percentile 0.1: 2026-06-03 Percentile 1: 2026-06-09 Percentile 5: 2026-06-16 Percentile 10: 2026-06-21 Percentile 20: 2026-06-27 Percentile 30: 2026-07-03 Percentile 40: 2026-07-09 Percentile 50: 2026-07-15 Percentile 60: 2026-07-21 Percentile 70: 2026-07-28 Percentile 80: 2026-08-08 Percentile 90: 2026-08-26 Percentile 95: 2026-10-05 Percentile 99: 2027-01-08 Percentile 99.9: 2027-04-20
The critic raises several valid concerns that warrant adjustment to my forecast. Let me address them systematically.
Political obstruction risk was underweighted: The Trump administration’s explicit opposition (“a shame,” suggesting companies seeking refunds lack “brilliance”) isn’t subtle. My original ~5% probability for “above upper bound” was too optimistic given overt executive resistance.
The secondary market signal: This is a crucial insight I underappreciated. If sophisticated financial actors believed 60-90 days was accurate, they wouldn’t be buying claims at discount. This market suggests informed parties expect significant delays.
Left tail inconsistency: Having a 0.1 percentile at 30 days post-launch while acknowledging the system was “blinky” and “overwhelmed” is logically inconsistent. The left tail should be pushed out.
CBP’s untested estimate: This is their first operation at this scale ($166 billion, 53 million entries). Their 60-90 day projection lacks empirical grounding.
Judicial pressure has teeth: Judge Eaton’s aggressive oversight and periodic reporting requirements create real pressure. Courts have enforcement mechanisms (contempt, sanctions) that even resistant administrations must weigh.
The “first” payment threshold matters: The question asks about ONE successful payment, not typical processing. Even amid systematic delays, some clean claims from well-resourced importers (FedEx, UPS, DHL with Day 1 filings, pre-registered ACH, sophisticated legal teams) may process successfully.
Strategic first payment possibility: Ironically, the critic’s point about “symbolic small payments” could work in favor of earlier resolution—the administration might allow some processing to avoid contempt charges while slow-walking the bulk.
Media coverage will be rapid: Given the enormous public interest, any confirmed receipt will be reported immediately, minimizing confirmation lag.
The critic suggests ~15-20% probability of no confirmed refund before August 12. I believe this is too pessimistic because:
I’m adjusting to approximately 10-12% probability of “above upper bound.”
Updated prediction:
Percentile 0.1: 2026-05-28 Percentile 1: 2026-06-04 Percentile 5: 2026-06-11 Percentile 10: 2026-06-17 Percentile 20: 2026-06-24 Percentile 30: 2026-06-30 Percentile 40: 2026-07-06 Percentile 50: 2026-07-12 Percentile 60: 2026-07-18 Percentile 70: 2026-07-24 Percentile 80: 2026-08-01 Percentile 90: 2026-08-10 Percentile 95: 2026-08-28 Percentile 99: 2026-10-25 Percentile 99.9: 2027-01-25
Left Tail Too Aggressive: The critic is right that June 5 (46 days from portal launch) is unrealistically optimistic even at 0.1 percentile. Given CBP’s explicit 60-day minimum processing time, plus ACH clearing and confirmation lag, the absolute fastest realistic scenario would be around 48-50 days. I’ll shift the left tail right by 3-4 days.
Right Tail Underweights Political Obstruction: The critic makes compelling points about Trump’s explicit opposition, the administration’s signaled intent to find alternative mechanisms, and the low ACH enrollment (~10%). My original 5% for “above upper bound” was indeed at the low end of my stated 5-10% range. I’ll increase this to approximately 6-7%.
Confirmation Lag Underweighted: The critic’s point about companies potentially staying quiet to avoid political backlash is valid. However, I expect trade publications (Journal of Commerce, etc.) will actively pursue this story, and at least one company will confirm receipt.
Judicial Oversight Provides Real Counterweight: The CIT is actively monitoring and requiring progress reports. Judge Eaton has been aggressive. This limits the administration’s ability to completely stonewall.
Fiscal Pressure is Meaningful: $22M/day in accruing interest creates genuine Treasury urgency. This isn’t just theoretical—it’s a compounding liability.
Day 1 Major Filers Have Strong Incentives: UPS, FedEx, DHL, and Learning Resources Inc. filed immediately and have both the resources and PR motivation to publicize receipt quickly.
The secondary market for tariff claims suggests sophisticated actors expect both eventual payment AND meaningful delays. This supports a moderately later median without extreme pessimism on “above upper bound.”
The critic’s suggested distribution was slightly too pessimistic in my view, particularly at the 90th percentile (August 7 seems too late given strong pressures for some refunds to process). I’m adopting a middle ground.
Updated prediction: Percentile 0.1: 2026-06-08 Percentile 1: 2026-06-14 Percentile 5: 2026-06-19 Percentile 10: 2026-06-23 Percentile 20: 2026-06-28 Percentile 30: 2026-07-03 Percentile 40: 2026-07-08 Percentile 50: 2026-07-13 Percentile 60: 2026-07-18 Percentile 70: 2026-07-23 Percentile 80: 2026-07-29 Percentile 90: 2026-08-05 Percentile 95: 2026-08-14 Percentile 99: 2026-09-12 Percentile 99.9: 2026-11-10
The critic makes a compelling point about internal consistency that I must address directly.
1. Internal logical consistency on the 60-day floor: The critic is absolutely right. I stated the 60-day CBP minimum is a “hard floor” but then placed P10 at June 15 (Day 56). This is genuinely inconsistent with my own stated reasoning. If I believe the 60-day estimate is meaningful, my left tail should respect it more rigorously.
2. First-mover hesitancy: I hadn’t fully considered this political dynamic. Given Trump’s explicit comments about companies being “brilliant” if they don’t seek refunds, the first company to publicly announce becomes a potential political target. This creates incentive for companies to receive refunds quietly and delay or avoid public announcements.
3. ACH enrollment as hard blocker: The 10% enrollment figure is concerning. While major shippers certainly have ACH established, this could create unexpected bottlenecks for claims that appear “clean” but lack proper banking setup.
Major shipper advantage remains critical: UPS, FedEx, and DHL are institutionally sophisticated, filed Day 1, have pre-established ACH relationships, and have PR incentives to announce they’re getting money back for their customers. They’re the most probable first recipients.
Learning Resources as symbolic candidate: The plaintiff company has maximum PR incentive to publicize immediately. CBP might even prioritize them for optics—though the administration might also delay them as retaliation.
The secondary market discount signal cuts both ways. While it suggests timeline uncertainty, it also confirms sophisticated actors believe refunds will ultimately be paid. A 10-15% discount for 90-day expected payment isn’t unusual financing cost—it may reflect liquidity value rather than pessimism about payment timing.
I’m adopting the critic’s distribution almost entirely. The left tail should properly respect the 60-day guidance while allowing for extreme outlier scenarios (a showcase fast-track case). The median at July 9 (Day 80) sits appropriately in the middle of the 60-90 day range plus confirmation lag. The ~85% probability before August 12 remains reasonable given judicial oversight balanced against political obstruction risk.
Timeline logic:
This makes P20 at June 23 appropriate—20% probability of confirmed receipt by the earliest realistic date under normal processing.
Updated prediction:
Percentile 0.1: 2026-06-01 Percentile 1: 2026-06-07 Percentile 5: 2026-06-13 Percentile 10: 2026-06-18 Percentile 20: 2026-06-23 Percentile 30: 2026-06-28 Percentile 40: 2026-07-03 Percentile 50: 2026-07-09 Percentile 60: 2026-07-15 Percentile 70: 2026-07-22 Percentile 80: 2026-07-31 Percentile 90: 2026-08-15 Percentile 95: 2026-09-02 Percentile 99: 2026-10-25 Percentile 99.9: 2026-12-25
The critic makes an excellent point about the mathematical floor created by the sequential validation + processing timeline. Let me work through this more carefully.
Minimum theoretical timeline:
This means anything before late June is essentially impossible under CBP’s stated parameters. My previous P0.1 of June 1 and P5 of June 12 were indefensible given the documented 2-4 week validation period followed by 60-90 day processing.
The “first” refund is the extreme left tail: We’re asking about the single fastest-processed claim among millions. Major shippers with pre-staged documentation, dedicated CBP relationships, and perfect ACH setup could plausibly receive expedited validation and near-minimum processing.
Government estimates often include buffer: The 60-90 day window may be conservative for public expectation management. A handful of simple claims might be processed in 55-58 days after acceptance.
Judicial oversight creates urgency: Judge Eaton’s aggressive posture and required progress reports add accountability that could push CBP toward efficiency.
The distribution should:
I’m accepting the bulk of the critic’s rightward shift while maintaining slightly more mass in early July than they suggest, based on the “first refund” framing and major shipper positioning.

Agent Forecast (date, confidence: medium)
Base Rate: CBP’s own revised guidance of 60-90 days from CAPE Declaration acceptance (Supply Chain Dive, April 10, 2026). From April 20 portal launch, that yields June 19 – July 19, 2026. Adjusting for acceptance delay (likely 1-2 weeks from Day-1 glitches) shifts the effective window to approximately early July – early August, which is where the adjusted distribution now concentrates its mass.

Reviewer Panel:
Reviewer (reasoning)
The forecast relies too heavily on CBP’s 60–90-day guidance without adjusting for real-world acceptance lags, ACH‐enrollment delays, and the likely multi-week gap between actual receipt and public confirmation per the resolution criteria. It also downplays the odds that public announcements (especially from major shippers) will trail receipt by several weeks or even a quarter, skewing confirmations into July or August. Finally, it treats ‘next-business-day’ reliquidations as a substantial early tail without solid data on what share of entries qualify.
Objections:
Reviewer (calibration)
The forecast appears overly optimistic regarding the timeline for the first publicly confirmed refund, underestimating the combined friction from system launch glitches, the massive scale of the program, the low rate of ACH setup among importers, and the additional lag introduced by the public confirmation requirement. While the 60-90 day guideline is central, these factors likely push the earliest plausible resolution towards the later end of that window or slightly beyond.

Adjustment Rationale:
Shifted roughly 8 points of probability mass from the May–mid-June bins into the July and post-July 29 bins in response to converging reviewer critiques. Both reviewers correctly identified that I underweighted (a) the delay between April 20-21 portal submission and formal CAPE acceptance caused by Day-1 system glitches, (b) the ACH-enrollment bottleneck — <10% of importers had ACH set up as of early March, and the resolution criterion explicitly requires ACH receipt, not just CBP disbursement, and (c) the public-confirmation lag, which is especially severe because many large importers will not announce receipt until Q2 earnings calls starting mid-July. The weighted median now sits around July 1-8 (vs. late June in the draft), and the post-July 29 tail grew from 0.08 to 0.15 to reflect the realistic scenario where CBP pays on schedule but no importer publicly confirms until an earnings call or formal release. I kept the Jun 18 – Jul 1 bin at 0.22 (only slightly lower) because the 60-day CBP anchor of June 19 remains the most credible lower-bound milestone, and high-profile filers like UPS/FedEx/DHL have competitive and PR incentives to announce receipt promptly.

Model’s Answer:
Process Timeline Analysis: The CAPE portal launched April 20, 2026. CBP’s stated timeline is 60-90 days from claim acceptance (not submission). There’s a validation step before acceptance, meaning the clock starts perhaps 1-2 weeks after submission for earliest filers. This yields:
Why it could be earlier (before late June):
Why it could be later (after August 12):
Critical Assumptions:
Median estimate: Around July 7-9, 2026 (~78-80 days after portal launch), reflecting the midpoint of the 60-90 day window adjusted for validation lag, with the “first” payment being the fastest case among hundreds of thousands of importers.

Law firm analyses [S8, S9, S12, S14, S16, S19] (March–April 2026): High-quality specialized trade law secondary sources. Consistent with CBP guidance. The 45-day figure from earlier court filings [S8, S16] likely refers to reliquidation deadline under 19 U.S.C. § 1501, not full ACH disbursement. Factual with some analytical interpretation.
Flexport [S13] (April 22, 2026): Reputable logistics firm with operational visibility. Notes 56,497 enrolled importers, system bottleneck risks, $127B covered. Mix of fact and opinion.
Baker Tilly [S26] (April 21, 2026): Professional services firm actively tracking CAPE submissions in real time. Observational—no confirmed payments yet. Notes queue segmentation by CBP. Moderate reliability, recent.
CIT court filings/history [S17, S20, S23, S27, S28, S31]: Reliable legal record. CBP met all development milestones; government appeal deadline ~June 8. Factual.
Trump/Navarro statements [S22]: Political rhetoric (“years”), low predictive value for operational CBP processing speed. Weak evidence.
Section 301 analogy [S41]: Flexport estimate of 6–8 weeks post-approval for simple cases. Indirect analogy, useful but imprecise. Moderate quality.
HMT precedent [S32]: 4-year delay; different legal/administrative context, extreme outlier. Weak relevance.
Strong evidence:
Moderate evidence:
Weak evidence:
Resolution criterion—public confirmation requirement: This is structurally independent of CBP processing. Large public importers with investor relations obligations and active trade press coverage make this condition likely to be satisfied once payments begin. However, it adds ~1–2 week lag and ~10–15% probability of non-satisfaction even if payments occur. Moderate evidence for this being a binding constraint.
Prediction window: April 23 to August 12, 2026 (~111 days). The operative CBP processing window (June 19–July 19) falls within days 57–87 of this window.
If timeframe halved (~56 days, deadline ~June 18): The 60-day floor would barely be reached. Most payments would fall outside the window; probability of “above upper bound” would rise dramatically to ~70–80%. The question would essentially hinge on whether CBP processes any clean submission in 45 days or fewer.
If timeframe doubled (~222 days, deadline ~December 1): The government appeal risk becomes less critical (appeal would likely be resolved by then), and CBP would have ample time to process all claims. “Above upper bound” probability would drop to ~5–10%, driven mainly by the public confirmation requirement. The distribution would shift significantly left toward June–July.
This sensitivity analysis confirms that the current August 12 deadline is reasonably well-positioned to capture most of the distribution but leaves meaningful tail risk of non-resolution.
Starting base rate: Outside view places the distribution concentrated in June 19–July 19, with ~35–40% probability of “above upper bound.”
Factors shifting from base rate:
CBP’s institutional track record in this case is strong (met all milestones, launched on schedule). This shifts the distribution slightly left (toward earlier payment) relative to a generic government processing baseline. However, this is a novel system at unprecedented scale, limiting how much weight to give this.
Government appeal risk is real but constrained. The Federal Circuit already rejected a 90-day stay [S36]. Courts have shown skepticism toward delay tactics. However, a new appeal on different grounds could succeed. I estimate ~18–22% probability of a successful stay halting disbursements. This is a key driver of “above upper bound” probability.
Public confirmation requirement adds uncertainty. Trade press (Journal of Commerce, Law360, Supply Chain Dive) actively covers tariff refund stories. Baker Tilly and Flexport are actively tracking. Large public importers (e.g., Walmart, Target, major retailers) have investor relations obligations. I estimate ~85–90% probability that if payments occur within the window, a qualifying confirmation will be published before August 12. This means ~10–15% of the “above upper bound” probability comes from this condition alone.
Processing speed uncertainty. The 45-day figure from court filings vs. 60–90 day official guidance suggests CBP may process some clean submissions faster than the stated minimum. Baker Tilly’s queue segmentation observation supports this. I assign ~15% probability to first payment occurring before June 19 (the 60-day floor).
Combined “above upper bound” probability: ~35% (government stay ~20% + processing delays beyond Aug 12 ~5% + no public confirmation despite payments ~10%).
Conditional distribution (given resolution within range):
Scenario 1: Government appeal/stay granted before June 8 (~18% probability)
Scenario 2: CBP processes early clean submissions in ~45 days; importer publicly confirms (~12% probability)
Scenario 3: CBP processes within stated 60-day window; importer confirms receipt (~28% probability)
Scenario 4: CBP processes near 90-day ceiling; importer confirms receipt (~22% probability)
Scenario 5: No qualifying public confirmation before August 12 despite payments occurring, OR processing delays beyond 90 days (~20% probability)
Total “above upper bound” probability: ~38% (Scenario 1: 18% + Scenario 5: 20%) Total within-range probability: ~62% (Scenarios 2–4)
Probability-weighted percentiles (unconditional):
Mapping scenarios to the full unconditional distribution:
Cumulative within-range:
This means:
Checking ±10% sensitivity:
The distribution is right-skewed with a heavy right tail reflecting the “above upper bound” probability.
1. Target variable: Date (YYYY-MM-DD) of first ACH refund receipt by importer via CAPE, confirmed by credible public source, between April 23 and August 12, 2026. ✓
2. Outside view base rate: June 19–July 19 window (CBP’s stated 60–90 day range), ~35–40% “above upper bound.” My inside view maintains this structure with minor adjustments. ✓
3. Consistency check: Implied median ≈ July 1–5; mean ≈ July 8 (pulled right by “above upper bound” tail); this aligns with my justification that most within-range outcomes cluster in late June–mid July with a heavy right tail. ✓
4. Key evidence:
5. Blind spot: The government files an appeal AND gets a stay before June 8, halting all disbursements → outcome above upper bound. This would push the outcome up (no resolution within range). I’ve assigned ~18% to this. If this probability should be higher (~30%), my 80th/90th percentiles should be pushed further right. I’ll maintain current estimates given the Federal Circuit’s prior rejection of a stay.
6. Status quo: The world changes slowly. CBP has been proceeding on schedule. The most likely outcome is that the process continues as planned, with first payments in the June–July window. The status quo slightly favors the June 19–July 19 range.
7. Technicalities: Percentiles strictly increasing ✓; units are YYYY-MM-DD ✓; values fall within stated bounds (2026-04-23 to 2026-08-12) ✓.

I’ll work through this systematically.

Political/risk sources (lower quality for timing, moderate for risk):
Key distinction: 45-day figure comes from court filings (legal obligation for reliquidation under 19 U.S.C. §1501); 60–90 days is the official CBP guidance for full ACH disbursement. These are not contradictory—reliquidation can happen at 45 days, ACH payment follows.
Strong evidence:
Moderate evidence:
Weak evidence:
Resolution-specific evidence: The resolution criteria require importer public confirmation, not just CBP disbursement. This adds a second-order uncertainty. Large public companies (retailers, manufacturers) with investor relations obligations are most likely to confirm. Trade publications (Journal of Commerce, Law360) actively cover this story. Historical GSP refund programs saw press coverage within ~7–14 days of first payments. This adds roughly 7–14 days to the distribution but doesn’t dramatically shift it.
Prediction timeframe: 110 days from April 23 to August 12. The relevant window for actual payment is June 4–July 19 (45–90 days from portal launch). Public confirmation likely follows payment by 7–14 days.
If halved (55 days): Resolution deadline would be ~June 17. Under this scenario, only the most optimistic 45-day scenario would resolve within the window. Probability of “above upper bound” would rise to ~70%.
If doubled (220 days): Resolution deadline would be ~November 29. Under this scenario, virtually all plausible payment scenarios would resolve within the window. “Above upper bound” probability would drop to ~15% (primarily government appeal risk).
The current 110-day window is well-matched to the stated 60–90 day processing window, meaning the primary uncertainty is not the deadline but rather (1) government appeal risk and (2) whether a qualifying public confirmation occurs.
Outside view base rate: Reference class (GSP 2018/2020, Section 301 2020–21) suggests 50th percentile at ~38 days post-authority, 90th at ~75 days. Adjusted for +10 day public confirmation lag: 50th at ~48 days (≈June 7), 90th at ~85 days (≈July 14).
Key adjustments from outside view:
Government appeal risk (moderate-strong evidence): ~25–30% probability of a stay being granted before June 8. This is higher than in most reference-class cases (GSP renewals had no appeal risk; Section 301 exclusions were administrative, not court-ordered). This shifts ~25–30% of mass to “above upper bound.” The DOJ’s prior failed stay attempt (S36) slightly reduces this probability.
Scale and complexity (moderate evidence): 53 million entries, 330,000 importers is unprecedented in CBP refund history. This creates bottleneck risk not present in smaller programs. However, Phase 1 covers only ~60% of entries and the automated CAPE system was specifically designed for this volume. Net effect: modest rightward shift.
Public confirmation requirement (moderate evidence): This is the most underappreciated factor. Even if CBP disburses on schedule, the question requires a qualifying public source. I estimate ~20–25% probability that payments occur but no qualifying confirmation is published before August 12. Large importers (Walmart, Target, Amazon) are most likely to confirm through investor relations channels. Trade press is actively covering this story.
CBP’s track record on this specific case (strong evidence): CBP met every court-imposed development milestone, launched on schedule April 20, and has 56,497 importers pre-enrolled. This is stronger execution than typical CBP IT projects. Slightly reduces delay risk.
Net adjustment: Outside view 50th percentile shifts from ~June 7 to ~June 25 (accounting for scale complexity and confirmation lag). “Above upper bound” probability rises from ~10% (reference class) to ~38% (government appeal + no confirmation scenarios).
Scenario 1: Government stay granted before June 8, no payments before August 12
Scenario 2: No stay; CBP processes early clean submissions in ~45 days; importer publicly confirms receipt
Scenario 3: No stay; CBP processes within stated 60-day window; qualifying public confirmation published
Scenario 4: No stay; CBP processing delayed to 75–90 day range; qualifying confirmation published
Scenario 5: No stay; payments occur within window but no qualifying public confirmation before August 12
Total probability of “above upper bound”: 22% + 15% = 37% Total probability of resolution within window: 63%
Probability-weighted distribution within the 63% that resolves:
Conditional on resolution within window:
Unconditional percentiles (including 37% “above upper bound” mass):
The question resolves as a date or “above upper bound.” Since I must provide date percentiles:
Percentile 10 (lowest): Should reflect the optimistic tail where early clean submissions process in ~45 days and confirmation comes quickly. June 8, 2026 (49 days from portal launch, accounting for confirmation lag).
Percentile 20: Early processing within 55 days + quick confirmation. June 20, 2026.
Percentile 40: On-schedule 60-day processing + 7-day confirmation lag. July 1, 2026.
Percentile 60: Slight delays, 70-day processing + 10-day confirmation lag. July 15, 2026.
Percentile 80: Near the 90-day ceiling with confirmation lag, or early confirmation in a delayed scenario. August 3, 2026.
Percentile 90: Captures the tail where payments are delayed to 90+ days or confirmation is slow, but still within window. August 10, 2026.
The 37% “above upper bound” mass means that ~37% of the time, the outcome falls outside the range entirely. The percentiles above represent the distribution as if the question resolves within the window, but since the question asks for date values, the upper percentiles are pushed toward August 12 to reflect the probability mass that would otherwise be “above upper bound.”
Consistency check: Implied median ≈ July 1–5; mean ≈ July 5–10 (right-skewed due to delay risk). This aligns with CBP’s 60-day floor (June 19) being the most likely “on-schedule” date, with rightward skew from bottlenecks and confirmation lag.
Target variable: Date of first ACH payment receipt confirmed by importer via qualifying public source, between April 23 and August 12, 2026.
Outside view base rate: Reference class (GSP/Section 301 refunds) suggests 50th percentile ~38–48 days post-launch. Adjusted for scale, appeal risk, and confirmation requirement → 50th percentile ~June 28–July 5. My distribution reflects this.
Consistency check: Implied median = ~July 1; mean = ~July 5; makes sense given 60-day CBP floor (June 19) with rightward skew from delays and confirmation lag. ✓
Top evidence pieces:
Blind-spot: Government files appeal AND gets a stay before June 8 → outcome is “above upper bound.” This would push the outcome UP (beyond August 12). I’ve weighted this at 22%, which may be slightly low given political signals.
Status quo: CBP is processing on schedule; no appeal has been filed. The status quo favors resolution within the window, supporting my 63% in-window probability.
Technicalities: Percentiles are strictly increasing ✓; units are dates (YYYY-MM-DD) ✓; values fall within stated bounds ✓.
Percentile 10: 2026-06-08 Percentile 20: 2026-06-20 Percentile 40: 2026-07-01 Percentile 60: 2026-07-15 Percentile 80: 2026-08-03 Percentile 90: 2026-08-10
Analysis:
Target variable / resolution criteria Date (YYYY-MM-DD) when the first importer actually receives an IEEPA tariff refund by ACH via CAPE, confirmed by a qualifying public source, between 2026-04-23 and 2026-08-12. CBP saying “processed/issued” is insufficient without importer receipt confirmation.

(c) Timeframe analysis We are forecasting roughly 50 to 110 days ahead from today (Apr 23, 2026), with the main action concentrated 42 to 90 days ahead.
(d) Justification / inside-view update The outside view already centered on late June to mid-July. The best inside-view update is not dramatic.
Main reasons:
So compared with the outside view, I modestly shift:
(e) Quantitative model I model 5 mutually exclusive scenarios:
Scenario 1: Earliest clean claims are accepted immediately, processed on the old ~45-day cadence, and a recipient/publication confirms promptly
Scenario 2: First payments track the low end of CBP’s official 60–90 day window, with public confirmation shortly after receipt
Scenario 3: Processing works, but queueing/review/acceptance friction pushes first receipt into the middle-to-late part of the stated window
Scenario 4: Payments occur, but qualifying public confirmation is delayed, sparse, or only appears near the deadline
Scenario 5: Appeal/stay or significant administrative/legal delay means no qualifying confirmation before deadline
Scenario mixture implications
This supports an implied median around early July, with 90th percentile very near the deadline.

Analysis:
(a) Source analysis (quality, date, fact vs opinion)
• S3 – CBP official CAPE page (20-Apr-26). Primary, very high quality. Facts: portal launch 20-Apr-26; refunds “generally 60-90 days after acceptance”; ACH-only. No opinion.
• S19, S12, S9, S14 (14-20 Apr-26 law-firm alerts). High quality secondary. Facts: Phase-1 scope, zero-tolerance error policy, ACH rule, 28-Apr court status report. Opinions: warn of possible delays.
• S8/S16/S20 (9 Mar–2 Apr-26 summaries of court filings). Medium quality secondary. Facts: CBP earlier said 45-day processing; system build progress. Opinion: refunds could start early June.
• S13/S26 (22-23 Apr-26 Flexport & Baker Tilly). Medium quality operational. Facts: 56 k importers enrolled for ACH (~82 % entries); queue-segmentation observed; no payments yet. Opinion: “clean” claims may move faster; bottlenecks possible.
• S31/S36/S22 (Mar–Apr-26 litigation commentary). Medium quality. Facts: government appeal deadline ≈ 8-Jun-26; prior stay request denied; Trump/Navarro “years” rhetoric. Opinion: odds of a stay range from “low” to “serious”.
• S10 (2-Jan-26 Fed. Reg.). Primary. Facts: paper checks discontinued, ACH mandatory. No opinion.
(b) Evidence weighting (relative to resolution criteria “first importer receives ACH refund and publicly confirms”)
Strong evidence
Moderate evidence
Weak evidence
(c) Timeframe analysis
• Horizon now to 12-Aug-26 = 111 days.
• If that window were halved (≈ 55 days), almost all mass inside the CBP 60–90-day guidance would be outside the window, so probability of “above upper bound” would jump sharply.
• If doubled (≈ 220 days) “above upper bound” tail would vanish unless a stay/appeal succeeds; the median would shift only a little earlier because first-payment timing is process-driven, not deadline-driven.
(d) Justification for shifts from outside view
Outside view (anchored on S3) centred late-Jun – mid-Jul. Inside view adjustments:
+10 % weight to an “early clean claim” 45-day scenario (S8/S26) → pulls left tail to ~9 Jun.
+15 % weight to “no qualifying public confirmation before 12-Aug” (confirmation hurdle + appeal risk) → fattens right tail beyond the question window.
+5 % weight to late-July/early-Aug delays (queue backlog + importer publicity lag).

Analysis: (a) Source analysis (quality, date, fact vs. opinion – abbreviated) S3 (2026-04-20, CBP portal page, primary): factual 60-90 day window, ACH-only.
S5 (2026-03-31, Supply-Chain Dive, trade press): factual 45-day pledge, some speculative delay comments.

S12 (2026-04-20, Butzel, law-firm): factual – 330 k importers, 60-90 day window; minimal opinion.
S13 (2026-04-22, Flexport blog, logistics provider): factual early traffic & 56 497 ACH-enrolled; opinion “queue segmentation”.
S21 (2026-02-20, trade law note): factual SCOTUS decision; opinion quoting Trump “years”.
S31/36 (court dockets, Feb-Apr 26, primary): factual appeal/stay deadlines, prior stay denial.
Overall: multiple independent primary/secondary sources give consistent facts; opinions concern possible legal delay.
(b) Evidence analysis (strength relative to resolution criteria) Strong:
• CBP’s official 60-90 day processing guidance (S3, S12) – structural, hard to shorten below 45 d.
• ACH-only refunds & 56 k importers already enrolled (S10, S13) – ensures payment mechanism exists.
Moderate:
• 45-day pledge in earlier court filings (S5, S8) – single source, now partly superseded.
• Historical Section-301 & GSP refunds (6-8 wk median) – similar but smaller scale.
• Legal appeal/stay possibility before 8 Jun (S31, S36) – clear mechanism but probability uncertain.
Weak:
• Trump/Navarro “years” rhetoric (S21) – political noise, not backed by actions.
• Anecdotal “queue segmentation” (S13) – early observation, unquantified.
(c) Time-frame analysis
Forecast window: 110 days (to 12 Aug 26). If halved (55 d) the window would close 17 Jun 26: only a 15 % chance of confirmation by then. If doubled (220 d) almost all scenarios would resolve, pushing the above-upper-bound probability near zero.
(d) Justification of shifts from outside view
Reference-class (8 historical CBP mass-refund programmes) shows 18-75 d lag from authority-final to first ACH receipt (median 38 d).
Up-shifts:
• Public confirmation requirement (+ ~10 d) – few importers issue releases immediately.
• 30 % chance DOJ wins a stay → ~80 % of those cases mean no payment before 12 Aug.
Down-shifts:
• Portal already live; 60 % of entries qualifying; 56 k importers ACH-ready – lowers odds of extreme (>90 d) delay if no stay.
Net: distribution right-shifted and fatter-tailed; 42 % mass on “no qualifying confirmation” before deadline.
(e) Quantitative model – mutually-exclusive scenarios
Distribution calibration Cumulative mapping of the above produces the percentile dates below. Values beyond 12 Aug reflect the unresolved-by-deadline scenario.

Forecast (percentiles, aggregated):
Per-model forecasts:
Rationale: Summary The median estimate of July 10, 2026, reflects a balance between the anticipated speed of simple refund claims and the strict criteria requiring public confirmation of actual receipt. U.S. Customs and Border Protection (CBP) opened the CAPE portal on April 20, 2026, to process approximately $166 billion in IEEPA duty refunds. The standard CBP timeline indicates an initial 10 to 45-day review and acceptance period, followed by 60 to 90 days to issue an ACH payment. This creates a standard processing window of 70 to 135 days. However, the first payments are expected to be processed faster, as Phase 1 covers previously liquidated, straightforward entries. The critical factor shaping these estimates is the strict confirmation requirement: government announcements of “disbursed” funds do not count. There must be an official corporate announcement, trade publication report, or major news story confirming an importer actually received the funds. This introduces a reporting lag that pushes the expected timeline out by several weeks. The 90th percentile stretches past the August 12 cutoff date, capturing the risk that systemic delays or corporate silence prevents a qualifying public confirmation in time.
Strongest Arguments for Sooner
Strongest Arguments for Later
Key Uncertainties
Our team’s thinking was primarily driven by the official operational timeline set by Customs and Border Protection (CBP) and the real-world filing behavior of major industry players. When the refund portal (CAPE) launched on April 20, 2026, it established a clear starting line. We focused on the transition from “filing” to “funds hitting the bank account.”
The crux of our reasoning relied on two competing timeframes: the optimistic “45-day” internal processing goal mentioned in legal filings and the more conservative “60–90 day” window provided in public guidance to trade organizations. We weighed the high likelihood of early action by large-scale integrators like UPS and FedEx, who filed claims on day one and have the sophisticated infrastructure to reconcile ACH payments quickly.
However, we also accounted for “frictions”—initial technical glitches with the new portal, the time required for Treasury Department disbursement, and the necessity of a public confirmation from an importer to resolve the question. This led us to favor a window where the first successful payments likely cluster just after the two-month mark, while maintaining a “tail” for potential administrative backlogs or reporting delays that could push the first confirmed receipt into the late summer.
