final rationale
Mean of 2 draws (0.16, 0.16). (0) Not resolved. BEA's latest release covers Q2 2026 at 2.2%. Q2 2027 has not started, and the advance estimate is scheduled for July 29, 2027, the contract's close date. (a) About 9 months remain until the resolving print. (b) The status quo is consensus-level growth of about 2%: the SPF median for 2027:Q2 is 2.1%, the FOMC sees 2.4% for 2027, IMF and WSJ about 2.1–2.3%, and CBO and OECD about 1.8%. That resolves NO, and a 3.5% print also resolves NO because the rule says more than 3.5. (c) NO path: Fed hikes and a 10-year yield near 5% weigh on H1 2027, AI capex growth moderates, and Q2 2027 prints somewhere between 1% and 3%. (d) YES path: AI capex keeps compounding (Goldman and Bridgewater put it at about 1.5pp a year), consumers hold up, and a trade or inventory swing adds 1–2 points, giving an advance print of 3.6% or more, as happened in 2023Q4, 2024Q2 and 2025H2. Base rates put latest-vintage quarters above 3.5% at about 20% in 2010–19 and 28% in 2022–26. Advance prints run about 0.35pp below final ones, and policy is tightening with the SPF risk skewed to the downside, so I land near 16%. That is close to the Kalshi anchor of 13% (bid) / 17% (mid), and I found no specific information that justifies a big move from it.

Planner reasoning
This is a long-horizon question on the US Q2 2027 advance GDP print, so the main anchors are the Kalshi price and the historical GDP growth distribution. FRED gives the history of real GDP growth rates for a base rate of quarters above 3.5% annualized, plus current macro conditions. Related GDP strikes on Kalshi and any Polymarket GDP markets help triangulate.

The question resolves on the one-decimal advance estimate published July 29, 2027. Consensus 2027 growth is about 2.1–2.3%, with tightening policy, so a print above 3.5% needs a large upside surprise, though recent quarters have been volatile (Q3 2025 4.4%, Q4 2025 0.5%, Q3 2026 nowcast 3.6%). - base rate: The outside view puts the chance of a >3.5% advance print at roughly 15–25%. Over 2010–2019 about 20% of quarters exceeded 3.5%, and 2022–26 ran about 28%. Professional consensus for 2027:Q2 is about 2%, with a quarterly volatility of around 2 points and recent prints already hitting 3.6–4.0%. Consensus and CBO both sit well below the threshold. - yes case: The best YES case is a capex-led upside surprise on top of a noisy trade and inventory component. That would need an upside of more than 1.4 points over the SPF 2.1% median, which is within the roughly 2-point quarterly volatility. Every forecaster source I found sits well below the strike, so YES depends on a surprise rather than a forecast. - no case: A YES needs a one-decimal advance print of 3.6% or more, roughly 1.5 points above every consensus source for 2027. It would also need to come in a tightening cycle, with AI-capex growth expected to fade and a downside-skewed risk balance. The case for NO is mainly the consensus gap and the strict ">3.5" wording. The main counter is quarterly volatility of about 2 points and the tendency for advance prints to be revised up.

- [2027-07-29] BEA's 2027 schedule has the Q2 2027 GDP Advance Estimate at 8:30 AM on July 29, 2027. That is the resolution release, and it falls on the contract's trading-close date. Later Q2 releases are the second estimate on Aug 25 and the third on Sep 30, 2027. https://www.bea.gov/news/schedule/next-year - [2026-09-30] BEA's third estimate put Q2 2026 real GDP at 2.2% SAAR, revised up from 1.5% in the advance and second estimates. Q1 2026 was revised to 2.5%. The release included the 2026 annual update. https://www.bea.gov/sites/default/files/2026-09/gdp2q26-3rd.pdf - [2026-09-30] Real final sales to private domestic purchasers grew 4.6% in Q2 2026. Real GDI grew 2.6%. The PCE price index rose 5.0% SAAR. https://www.bea.gov/news/2026/gdp-third-estimate-industries-corporate-profits-state-gdp-and-state-personal-income-2nd - [2026-09-30] Recent quarterly growth: Q1 2025 -0.5%, Q2 2025 3.8%, Q3 2025 4.4%, Q4 2025 0.5%. Calendar-year 2025 growth was 2.1%. Quarterly prints above 3.5% have happened, but not in 2026 so far. https://www.nerdwallet.com/finance/learn/gdp-report - [2026-10-15] The Atlanta Fed GDPNow estimate for Q3 2026 is 3.6%, unchanged from Oct 8. It peaked at 6.2% on Aug 3. Inventories contribute about 1.9 points of that. The next update is Oct 20. This is a Q3 nowcast, not Q2 2027. https://investinglive.com/central-banks/atlanta-fed-gdpnow-holds-at-3-6-for-q3-as-consumer-spending-outlook-improves/ - [2026-10-29] The next scheduled catalyst is the Q3 2026 advance GDP release on Oct 29. Others follow: second estimate Nov 25, third estimate Dec 23, and the Q4 advance on Jan 28, 2027. https://www.bea.gov/news/schedule - [2026-10-11] The WSJ economist survey (71 respondents, conducted Oct 2–7) has full-year GDP growth of 2.42% for 2026 and 2.14% for 2027. https://www.economicgreenfield.com/2026/10/11/the-october-2026-wall-street-journal-economic-forecast-survey/ - [2026-10-13] The IMF's October WEO has US growth at 2.3% in both 2026 and 2027. https://www.cnbc.com/2026/10/14/bond-yields-debt-deficit-treasury.html - [2026-10] U.S. Bank forecasts 2.1% Q4/Q4 growth in 2027. It expects another 75bp of Fed hikes between Oct 2026 and Mar 2027. TD Economics (about Sep 17) sees 2027 growth "just north of 2%". Goldman Sachs (Oct 11) sees 2.2% for 2027. https://www.usbank.com/corporate-and-commercial-banking/insights/economy/outlook/monthly.html - [2026-10-17] A Substack outlook (not a primary source) expects growth to slow, with the clearest slowdown in H1 2027. It cites a 10-year yield of 5.26%, payroll gains of about 51k a month, and narrow AI-led capex strength. https://marlonwhittock.substack.com/p/us-macro-and-equity-outlook-october - [2026-10-15] Context from news headlines: the Fed has been hiking rates, with a 25bp hike on Sep 16. Oil prices are elevated amid Middle East/Iran tensions. US stocks sold off in mid-October on "AI bubble" worries. https://investinglive.com/central-banks/atlanta-fed-gdpnow-holds-at-3-6-for-q3-as-consumer-spending-outlook-improves/ - [2026-06] OECD (June) projects US growth of 1.8% in 2027, with energy-shock drag. https://www.oecd.org/en/publications/2026/06/oecd-economic-outlook-volume-2026-issue-1_8be0dba6/full-report/united-states_f8b45458.html BOTTOM LINE: No Q2 2027 data exist yet. The question resolves on the one-decimal advance estimate published July 29, 2027. Consensus 2027 growth is about 2.1–2.3%, with tightening policy, so a print above 3.5% needs a large upside surprise, though recent quarters have been volatile (Q3 2025 4.4%, Q4 2025 0.5%, Q3 2026 nowcast 3.6%). NOT FOUND: A consensus forecast specific to Q2 2027 quarterly growth. Kalshi or other market prices (deliberately not searched). The official Q3 2026 advance estimate, which is due Oct 29.
report: base rate
- [2026-10-18] The only 2027:Q2 forecast I found is a median of 2.1% annualized, from 32 Philadelphia Fed Survey of Professional Forecasters (SPF) panelists. The survey was fielded in August and released 2026-08-14. The panel gave a mean 22.0% chance of a negative 2027:Q2. Forecasters see 2027 full-year growth (annual average) at 2.2% and unemployment at 4.3%. The SPF publishes no probability for Q2 growth above 3.5%. https://www.philadelphiafed.org/surveys-and-data/real-time-data-research/spf-q3-2026 - [2026-10-18] SPF track record on 2027:Q2: the median was 1.9% in the Q2 survey (May) and 2.1% in the Q3 survey (August). This is a long-horizon, low-dispersion consensus. Its 2026 quarterly medians (2.0–2.6%) were never near 3.5%, yet actual quarters ranged from 0.2% to 4.0%. https://www.philadelphiafed.org/surveys-and-data/real-time-data-research/spf-q2-2026 - [2026-09-30] Latest-vintage BEA quarterly real GDP growth, from the FRED series: - 2025: Q1 0.1, Q2 4.0, Q3 3.9, Q4 0.2. - 2026: Q1 2.5, Q2 2.2 (third estimate). - Quarters are volatile, with a standard deviation of roughly 2 points outside the pandemic. Trade, inventory and government swings drive much of it. https://fred.stlouisfed.org/series/A191RL1Q225SBEA - [2026-09-30] Base rate, computed by me from FRED latest-vintage data (not advance estimates). Quarters above 3.5%: - 2010Q1–2019Q4: 8 of 40 (20%). - 2022Q1–2026Q2: 5 of 18 (28%): 2023Q3 4.5, 2023Q4 3.6, 2024Q2 3.6, 2025Q2 4.0, 2025Q3 3.9. - 2020–21 pandemic quarters excluded. - Pre-2000 quarters were above 3.5% far more often, but trend growth was higher then. - Several prints were only marginally above 3.5% (3.6%), so one-decimal rounding matters. https://fred.stlouisfed.org/data/A191RL1Q225SBEA.txt - [2026-10-15] The Atlanta Fed's GDPNow tracks Q3 2026 at 3.6%. Inventories contribute about 1.9 points of that, roughly half. The BEA advance Q3 estimate is due 2026-10-29. This is a nowcast for a different quarter, but it shows that above-3.5% prints are occurring now. GDPNow was 5.0–6.2% in early August and fell to 3.6–3.7% by October, so the readings are noisy. https://investinglive.com/central-banks/atlanta-fed-gdpnow-holds-at-3-6-for-q3-as-consumer-spending-outlook-improves/ - [2026-07-30] The BEA advance estimate for Q2 2026 was 1.5%, below the ~2.1% forecast. It was revised to 2.2% in the third estimate, so the advance estimate can differ from later vintages by 0.7 points. The question resolves on the advance estimate, which is expected around 2027-07-29/30. https://www.bea.gov/news/2026/gdp-advance-estimate-2nd-quarter-2026 - [2026-09-30] Advance estimates of 2026 Q1 and Q2 came in well under 3.5%. The advance Q1 print was 2.0% and the advance Q2 print was 1.5%. Late 2025 showed 0.2% in Q4. https://www.bea.gov/taxonomy/term/791 - [2026-09 / FRED retrieval] The FOMC median projection for Q4/Q4 real GDP growth is 2.3% for 2026 and 2.4% for 2027. https://fred.stlouisfed.org/series/GDPC1MD - [2026-02] The CBO projects real GDP growth of 2.2% in 2026 and 1.8% in 2027, and about 1.8% a year after that. https://www.cbo.gov/publication/62105 - [2026-04] The White House FY2027 budget (assumptions finalized in November 2025) projects 3.1% a year for 2027–29. That is an outlier above the Blue Chip and FOMC consensus, and administration forecasts are typically optimistic. https://www.whitehouse.gov/wp-content/uploads/2026/04/ap_1_assumptions_fy2027.pdf - [2026-10-01] Deloitte's baseline expects growth to moderate over the next two years, with business investment growth fading in 2027. Its downside scenario has 2027 growth of 0.2%. https://www.deloitte.com/us/en/insights/topics/economy/us-economic-forecast/united-states-outlook-analysis.html - [2026-10-02] Kalshi's own Q2-2027 GDP ladder (a sibling contract on the same event) showed Above 1.5% at 58%, Above 2.0% at 47% and Above 2.5% at 43%. This is a stale snapshot, and it shows no 3.5% strike. https://kalshi.com/markets/kxgdp/us-gdp-growth/kxgdp-27jul29 BOTTOM LINE: The outside view puts the chance of a >3.5% advance print at roughly 15–25%. Over 2010–2019 about 20% of quarters exceeded 3.5%, and 2022–26 ran about 28%. Professional consensus for 2027:Q2 is about 2%, with a quarterly volatility of around 2 points and recent prints already hitting 3.6–4.0%. Consensus and CBO both sit well below the threshold. NOT FOUND: A Blue Chip or Wall Street bank forecast specific to 2027:Q2. The SPF probability distribution for 2027 annual growth (it is only in chart images). A Kalshi price for the 3.5% strike. A historical hit rate of advance estimates specifically, since I used latest-vintage data.
report: yes case
YES means: BEA's Advance Estimate of Q2 2027 real GDP (seasonally adjusted annualized rate, one decimal, published about July 29, 2027) is 3.6% or higher. - [2026-08-14] The SPF median for 2027:Q2 is 2.1%. The same survey raised its 2026:Q4 median from 1.6% to 2.3%, which shows the panel revising up. It also lowered the mean chance of a negative 2027:Q2 only slightly, from 23.0% to 22.0%. The YES case is that consensus tends to chase the data, and recent prints have beaten it. The 3.5% strike is about 1.4 points above the median. https://www.philadelphiafed.org/surveys-and-data/real-time-data-research/spf-q3-2026 - [2026-08-07] Goldman Sachs Research expects US AI investment to rise from 1.8% of GDP in 2026 to 2.5% in 2027. That is a 0.7-point rise in the level of AI capex as a share of GDP. Goldman's portfolio strategists say consensus 2027 capex numbers are "likely too conservative". Goldman also says its leading indicators of AI capex sit near the top of their range since 2022. This is the most direct mechanism for an above-trend 2027 quarter. https://www.goldmansachs.com/insights/articles/global-investment-is-forecast-to-exceed-1-trillion-in-2026 - [2026-09 (about 27 days before 2026-10-18)] Bridgewater estimates AI capex adds about 140bp to US growth in 2026 and about 150bp in 2027. That is a sustained add-on of about 1.5 points a year to whatever non-AI growth the economy produces. If the rest of the economy grows near 2%, a strong quarter could reach the mid-3s. Bridgewater notes much of this reflects chipmaker profits that are not recycled, so it likely overstates the demand effect. https://www.edwardconard.com/macro-roundup/bridgewater-forecasts-real-us-gdp-growth-of-2-8-in-2026-with-ai-capex-contributing-1-4pp-50-this-year-and-growing-to-1-5pp-in-2027/ - [2026-07-16] A capex tracker says hyperscaler 2027 capex estimates rose from about $530bn at the start of 2026 to almost $900bn. It also says estimates were revised up even through a July selloff. It attributes about 45% of recent real GDP growth to AI-related investment. If 2027 guidance keeps rising, equipment and structures investment could add far more than the forecasts built in earlier. This is a secondary source. https://www.matterfact.com/newsletter/2026-07-16-ai-capex-tracker-gdp-growth - [2026-10-05] The quarterly profile in the Richmond Fed table shows how swingy the components are. Imports moved from -29.3% to +12.5% across recent quarters. Exports ran -3.2% to +10.9%. Private inventories ran from -15.6 to -53.1 ($bn). Net exports swung from +4.4 to -1.0 points. A Q2 2027 trade or inventory swing of 1.5 to 2 points would turn a 2% core quarter into a 3.5%+ print. https://www.richmondfed.org/-/media/richmondfedorg/research/national_economy/national_economic_indicators/pdf/all_charts.pdf - [2026-08-18] GDPNow for Q3 2026 started at 5.0% on Jul 30 and peaked at 6.2% on Aug 3. It was 4.0% on Aug 18. SPF forecasters expected 2.5% for that quarter. Nowcasts have tracked well above SPF medians this year, so a nowcast-driven 3.5%+ print in 2027 is plausible. https://www.atlantafed.org/research-and-data/data/gdpnow/current-and-past-gdpnow-commentaries - [2026-09-03] The GAO reports $296bn in refunds in the 2026 filing season, up 17%. Those refunds include OBBBA's retroactive tips and overtime deductions. Yale Budget Lab and Principal both put the OBBBA boost at 0.2–0.4 points a year through 2027. Principal expects the refund windfall to support first-half spending. A repeat refund season in H1 2027, plus full business expensing, supports Q1–Q2 2027 spending. The support is small and not retroactive again, so it is a secondary factor. https://political.org/2026/09/03/trumps-one-big-beautiful-bill-delivers-296-billion-in-irs-refunds-rebutting-economic-pessimism/ and https://www.principalam.com/us/insights/macro-views/dissecting-obbba-front-loaded-fiscal-boost - [2026-10-02] Q2 2026 was a reversal case: the advance estimate was 1.5%, the final 2.2%, with final sales to private domestic purchasers at 4.6% (see colleagues' Sept 30 note). Consumer spending contributed 2.51 points in Q2 2026. If a quarter's trade or inventory drag reverses, as it did in the 2025 H2 export rebound, a headline above 3.5% is reachable. The RBC note on Q3 2025 says the advance print was a full point above consensus at 4.3%. https://www.rbc.com/en/economics/us-analysis/us-data-flashes/q3-u-s-gdp-beats-expectations-but-shutdown-clouds-q4-outlook/ - [2026-10-18] The single most likely YES path has three prerequisites: 1. AI-related equipment, software and data-center investment keeps compounding into 2027 (Goldman, Bridgewater). 2. Consumer spending holds near 3% despite Fed hikes. 3. Net exports or inventories add roughly 1 point in Q2 2027, e.g. after import front-loading unwinds. Together these would lift the underlying 2–2.5% pace past 3.5%. That is my synthesis of the sources above, not a published forecast. Marginal prints of 3.6% have occurred (2023Q4, 2024Q2, per colleagues' base-rate note). BOTTOM LINE: The best YES case is a capex-led upside surprise on top of a noisy trade and inventory component. That would need an upside of more than 1.4 points over the SPF 2.1% median, which is within the roughly 2-point quarterly volatility. Every forecaster source I found sits well below the strike, so YES depends on a surprise rather than a forecast. NOT FOUND: A Q2 2027-specific forecast above 3.0% from any credible forecaster. The SPF probability bins for 2027 growth (chart images only). Any Q2 2027 nowcast or bank quarterly path. Fiscal stimulus beyond OBBBA scheduled for H1 2027.
report: no case
YES means: the BEA's advance estimate of Q2 2027 real GDP, published at one decimal around July 29, 2027, is 3.6% or higher at a seasonally adjusted annual rate. A print of exactly 3.5% resolves NO. - [2026-09-16] Resolution technicality: the rule says "more than 3.5". The value used is the one-decimal advance figure, so 3.5 is NO and only 3.6 or more is YES. Several recent quarters sat just above the line at 3.6, so the rounding rule matters. The contract resolves on the advance estimate only, so later revisions are irrelevant. Source: https://www.bea.gov/news/schedule/next-year - [2026-09-16] The Sept 16 FOMC (fetched) raised its median 2027 GDP projection to 2.4% from 2.3%. A 3.6%+ quarter would still need about 1.2 points more than the Fed's own median year. The Fed's median 2027 unemployment projection is 4.1%, and the median 2027 core PCE projection is 2.5%. Chair Warsh called the hike "removing a dose of accommodation". The dot plot shows most members expecting rates above the current 3.75–4.00% by end-2027. Source: https://www.schwab.com/learn/story/fomc-meeting - [2026-10-13] Policy is tightening into the target quarter. Fed funds futures give about 90% odds that rates end 2027 at least 50bp above today's level. NY Fed's Williams is the dovish outlier: he sees one more hike in 2026 and none in 2027. September CPI (Oct 14) was 3.7% y/y, above expectations, and the market priced a 35% chance of an October hike. Rate hikes act with a lag of several quarters, so they weigh most on H1–mid 2027. Sources: https://www.cnbc.com/2026/10/13/john-williams-fed-rate-hikes-2027.html and https://finance.yahoo.com/economy/policy/articles/fed-interest-rate-hike-seems-195052044.html - [2026-10-16] Market-implied tightening is larger than the dot plot. As of Oct 11 there was a 34.7% probability of 100–175bp of further hikes by Sept 2027. Warsh has named inflation as the priority. Higher rates plus a 10-year yield near 5% (Sept 16) are headwinds for housing and rate-sensitive investment.

The AI-capex boom is the main prop for growth. Deloitte's downside scenario has an equity drop hitting consumption, with 0.2% growth in 2027. The upside needed for 3.6%+ would require AI capex to accelerate again, which the baseline does not assume.

The panel's risk skew is toward weakness, not an upside breakout. Source: https://www.philadelphiafed.org/surveys-and-data/real-time-data-research/spf-q2-2026 - [2026-07-30] Advance prints in 2026 ran below consensus. Q2 2026 advance was 1.5% against a 2.1% Reuters consensus. The Reuters range was 0.8–2.9%, so even the most bullish forecaster was under 3.5%. Source: https://www.nbcnews.com/business/economy/gdp-slowed-second-quarter-rcna589992 - [2026-01-07] Revision direction cuts against NO. The Richmond Fed brief (fetched) finds advance GDP is initially under-reported by about 0.35pp on average since 1983 (median 0.32). The revision standard deviation is 1.55pp. The Q2 2025 advance of 3.0% was later revised to 3.8%. This argues for slightly lower advance prints than final ones, which modestly favours NO on a first-print basis. The advance Q2 2026 print was revised up 0.7pp. Source: https://www.richmondfed.org/publications/research/economic_brief/2026/eb_26-01 - [2026-10-14] Status quo and mean reversion. Tradingeconomics' model gives about 2.1% for 2027. Q3 2026 GDPNow at 3.6% is about half inventory build, which tends to reverse in later quarters. Inventories subtracted 0.67pp in Q2 2026 (advance), so the swing is mean-reverting, not a trend. Sources: https://tradingeconomics.com/united-states/gdp-growth and https://www.nbcnews.com/business/economy/gdp-slowed-second-quarter-rcna589992 - [2026-10-17] The outlook piece cited by colleagues expects the clearest slowdown in H1 2027, and it is a low-quality source. It also notes the Q3 2026 S&P earnings growth of 29% is concentrated in semiconductors. Other forecasters, including OECD, Deloitte and the SPF, have the same direction. The OECD's risk assessment is "tilted to the downside", with elevated equity valuations and private-credit vulnerabilities. Sources: https://marlonwhittock.substack.com/p/us-macro-and-equity-outlook-october and https://www.cfodive.com/news/us-gdp-growth-slow-2027-oecd-forecast-Fed-inflation-economy-Federal-Reserve-ai/821930/ - [2026-09-16] The S&P 500 fell to six-week lows near 7,500 after the Fed meeting. The OECD names equity valuations as a downside risk. A wealth-effect reversal would hit consumption, which was 3.4% in Q2 2026 (advance). Sources: https://www.schwab.com/learn/story/fomc-meeting and https://tradingeconomics.com/united-states/gdp-growth BOTTOM LINE: A YES needs a one-decimal advance print of 3.6% or more, roughly 1.5 points above every consensus source for 2027. It would also need to come in a tightening cycle, with AI-capex growth expected to fade and a downside-skewed risk balance. The case for NO is mainly the consensus gap and the strict ">3.5" wording. The main counter is quarterly volatility of about 2 points and the tendency for advance prints to be revised up. NOT FOUND: A Q2 2027-specific consensus from Blue Chip or a bank, and any official Q3 2026 advance data (due Oct 29). I also found no historical hit rate for advance prints above 3.5%. The CNBC Williams page was inaccessible when I tried to fetch it, so the Williams and rate-futures figures come from search snippets.

(0) Not resolved. BEA's latest release covers Q2 2026 at 2.2%. Q2 2027 has not started, and the advance estimate is scheduled for July 29, 2027, the contract's close date. (a) About 9 months remain until the resolving print. (b) The status quo is consensus-level growth of about 2%: the SPF median for 2027:Q2 is 2.1%, the FOMC sees 2.4% for 2027, IMF and WSJ about 2.1–2.3%, and CBO and OECD about 1.8%. That resolves NO, and a 3.5% print also resolves NO because the rule says more than 3.5. (c) NO path: Fed hikes and a 10-year yield near 5% weigh on H1 2027, AI capex growth moderates, and Q2 2027 prints somewhere between 1% and 3%. (d) YES path: AI capex keeps compounding (Goldman and Bridgewater put it at about 1.5pp a year), consumers hold up, and a trade or inventory swing adds 1–2 points, giving an advance print of 3.6% or more, as happened in 2023Q4, 2024Q2 and 2025H2. Base rates put latest-vintage quarters above 3.5% at about 20% in 2010–19 and 28% in 2022–26. Advance prints run about 0.35pp below final ones, and policy is tightening with the SPF risk skewed to the downside, so I land near 16%. That is close to the Kalshi anchor of 13% (bid) / 17% (mid), and I found no specific information that justifies a big move from it.

(0) Not resolved. The BEA page shows only data through Q2 2026 at 2.2%; Q2 2027 has not started, and the advance estimate is due July 29, 2027. (a) That is about 9.5 months away, which leaves the full quarter's data still to come. (b) Status quo points to NO. The SPF median for 2027:Q2 is 2.1%, FOMC 2027 is 2.4%, WSJ/IMF/CBO are 1.8–2.3%, and the Fed is hiking into the target quarter, so a print of 3.6% or higher needs roughly a 1.5-point upside surprise. (c) NO: rate hikes, a 10-year yield near 5% and a possible equity/AI-capex pullback keep growth near 2%. Advance prints also run about 0.35pp below later vintages, and an exact 3.5% resolves NO. (d) YES: AI capex keeps compounding (Goldman, Bridgewater put it at roughly 1.5pp), consumers hold up, and a trade or inventory swing adds 1–2 points, as in Q2/Q3 2025 (4.0%/3.9%). The outside view supports a modest YES tail: about 20% of 2010s quarters and about 28% of 2022–26 quarters exceeded 3.5% in latest vintage, less for advance prints, with quarterly volatility of about 2 points. A normal distribution centred near 2.0% with SD of about 1.9 gives roughly 18–20%, and the downside-skewed policy backdrop trims that. The Kalshi bid is 13% and the ask 21%, a midpoint of about 17%; I land at 16%, close to the market anchor.
