Planner reasoning

Recession probability for 2027 hinges on current macro trajectory (GDP growth, yield curve, labor market) and forward-looking forecasts/market consensus. The Kalshi price is the anchor; FRED gives the underlying data and base rates for recession risk.

# Current state The market resolves Yes if two consecutive quarters of negative real GDP growth occur spanning Q4 2026–Q4 2027 (BEA definition). As of late June 2026, the US economy is expanding — latest GDP data shows Q1 2026 at $24,180B (positive growth), unemployment stable at 4.3%, and payrolls growing modestly. # Timeline of key events - **2020-05**: Current expansion begins (NBER trough) — confirmed - **2022–2023**: 10Y-2Y yield curve inverts deeply (~-100bps, deepest since 1981) — confirmed - **2024-Q4**: Fed begins rate-cut cycle — confirmed - **2025-Q4**: Philadelphia Fed SPF projects 2.1% real GDP growth for 2027 — confirmed - **2026-Q1**: Real GDP = $24,180B, positive growth continues — confirmed [FRED] - **2026-05**: Unemployment 4.3%, payrolls 159,001K — confirmed [FRED] - **2026-06**: T10Y2Y spread = +0.31% (positive, no longer inverted); Fed Funds = 3.63% — confirmed [FRED] - **2026-06**: Conference Board LEI +0.1% in May, but 6-month rate still negative — confirmed - **2026-06**: OECD forecasts US GDP slows to 1.8% in 2027 — reported - **2026-06**: NY Fed yield-curve model puts 12-month recession probability at ~15% — confirmed --- # Event Will there be a US recession in 2027 (two consecutive quarters of negative real GDP, Q4 2026–Q4 2027, per BEA)? # Outcomes to forecast - **Yes**: Two consecutive quarters of negative GDP growth within the Q4 2026–Q4 2027 window - **No**: No such sequence occurs # Kalshi market anchor **Current YES price: 44%** | 7-day change: +3pp | 30-day change: 0pp | Avg volume: 709 contracts/day | Range over 66 days: 33%–51%. Market is currently pricing near the midpoint with a slight recent uptick. # Sub-question answers 1. **Current Kalshi market price for 2027 recession?** — 44% YES on KXRECSSNBER-27 as of late June 2026, up 3pp over 7 days, flat over 30 days. [Kalshi direct] 2. **Recent GDP trajectory and momentum?** — Real GDP has grown each quarter through Q1 2026 ($24,180B), with Q4 2025→Q1 2026 showing healthy acceleration; momentum is positive but moderating. [FRED GDPC1] 3. **Leading indicator signals?** — Yield curve now +0.31% (re-steepened, no longer a red flag); unemployment stable at 4.3%; payrolls modestly positive ~170K/month. Conference Board LEI six-month rate still slightly negative. NY Fed model gives only ~15% 12-month recession probability as of May 2026. [FRED, NY Fed, Conference Board] 4. **Base rate and professional forecasts?** — Historical base rate: ~28% for any calendar year. SPF Q4 2025 projects 2.1% GDP growth for 2027. OECD projects 1.8%. White House projects 3.1% (outlier). Bayesian update with current indicators → ~42% central estimate. [FRED code analysis, Philadelphia Fed, OECD] 5. **Related prediction markets?** — Kalshi 2026 recession only ~17.5% (per news source); no active Polymarket markets found. Moody's puts 2026 recession risk at ~42%; Bloomberg survey ~30%. [Yahoo Finance, Kalshi related] # Key facts (high-confidence, factual) 1. [FRED] Real GDP Q1 2026: $24,180B; growth has been positive every quarter since Q2 2020 2. [FRED] Unemployment rate May 2026: 4.3%; stable range 4.3–4.5% since late 2025 3. [FRED] T10Y2Y spread June 2026: +0.31%; yield curve has fully re-steepened from 2022–23 inversion 4. [FRED] Federal Funds Rate June 2026: 3.63% (well below 2023 peak of ~5.3%) 5. [Code analysis] Historical recession base rate 1950–2024: 28%; current expansion at ~74 months, past the 68.8-month historical mean gap 6. [NY Fed] Yield-curve model recession probability for May 2027: ~15% 7. [Philadelphia Fed] SPF Q4 2025: 2.1% real GDP forecast for 2027 8. [OECD/CFO Dive] OECD forecasts 1.8% US GDP growth in 2027, risks "tilted to downside" # Cross-market signals - **Kalshi related**: 2026 recession ~17.5% (news-reported); no separate 2027 NBER market found beyond primary ticker - **Polymarket**: No active recession/GDP markets found - **Analyst/institution implied**: Moody's ~42% for 2026 (bleeds into 2027 risk); Bloomberg survey ~30%; Deloitte downside scenario shows -0.4% GDP in 2027 under AI investment bust # Analyst opinions and speculation - [JPMorgan] No near-term recession expected; "material headwinds" to keep growth weak through 2026 - [Deloitte] Downside scenario: AI investment pullback causes -0.4% GDP in 2027, -1% in 2028 — tail risk, not base case - [247WallSt/Yahoo] Market narrative: 2026 recession avoidance shifting concern to "delayed reckoning" in 2027 - [Conference Board] LEI recovering but 12-month growth rate still negative — "slower expansion ahead," not contraction signaled # Directional lean per outcome - **Yes (recession)**: Current expansion age >historical mean; residual monetary policy lag risk; LEI six-month rate negative; geopolitical/oil shock risk (Iran war referenced); Deloitte downside scenario plausible; market at 44% - **No (no recession)**: GDP momentum positive through Q1 2026; yield curve re-steepened; unemployment stable; Fed cutting (easing stance); NY Fed model only 15%; SPF consensus +2.1%; OECD +1.8%; no two-consecutive-negative-quarter signal in current data # Gaps / unknowns - No Q2/Q3/Q4 2026 GDP data yet available (resolution window starts Q4 2026) - Iran war energy shock magnitude unknown; could materially shift 2027 outlook - Fed reaction function to any 2026 slowdown is uncertain - AI investment cycle trajectory (bull vs. Deloitte bust scenario) unresolved # Calibration anchors - **Kalshi current YES price: 44%** (primary anchor) - Historical base rate: 28% (unconditional prior) - Bayesian posterior with leading indicators: ~42% (range 22–57%) - NY Fed model (15%) likely understates 2027 risk as it's a 12-month forward model as of mid-2026 - Professional forecasters consensus: ~2% GDP growth for 2027 = no recession in base case, but meaningful downside tail (~30–44% range across sources)

1. Both forecasters lean below the Kalshi anchor of 44% citing the NY Fed's 15% model, but they under-weight the brief's own caveat that this model "likely understates 2027 risk as it's a 12-month forward model as of mid-2026" — the resolution window extends to Q4 2027, making the NY Fed figure a materially shorter horizon than the question requires. 2. Neither forecaster adequately engages the expansion age argument: the brief notes the current expansion is ~74 months, past the 68.8-month historical mean, which combined with the unconditional 28% base rate and residual monetary lag (Fed Funds still at 3.63%, only partially unwound from 5.3% peak) represents a structural upward pressure they both dismiss too quickly. 3. Both forecasters ignore that the resolution definition spans Q4 2026–Q4 2027, a five-quarter window — meaning a slowdown beginning in Q4 2026 (only ~6 months away with no data yet) counts; neither discusses the probability of Q4 2026 turning negative as a plausible starting point given the still-negative LEI six-month rate. 4. The Moody's 42% recession probability for 2026 (which would obviously carry into 2027 risk) and Bloomberg's ~30% survey are mentioned in the brief but neither forecaster references them, creating an inconsistency where professional institutional views are selectively used (SPF/OECD bullish forecasts cited) while bearish institutional signals are ignored. 5. The geopolitical tail risk (Iran war energy shock referenced in the brief under "Gaps/unknowns") receives no quantitative weight from either forecaster, despite the brief explicitly flagging it as capable of "materially shifting the 2027 outlook" — this is a meaningful omission for a forecast horizon still 18 months out.

43% (50% confidence)

Yes: 43% No: 57%

Both forecasters leaned slightly below the 44% Kalshi anchor, but the critique fairly notes they under-weighted the five-quarter resolution window, expansion age, residual monetary lag, and geopolitical tail risk. These factors justify nudging back toward the market. With hard data still positive (GDP momentum, re-steepened curve, stable employment) but meaningful downside, I settle at 43%, essentially the market anchor.
