Planner reasoning

This is a long-horizon Kalshi tail-risk market on a US president resigning before Jan 2029. The dominant anchors are the current Kalshi price, the Polymarket equivalent, and the historical base rate (1 resignation in ~46 presidencies / ~250 years). Research should confirm market pricing, check for any live catalysts (impeachment momentum, health/succession news, 25th Amendment chatter), and compute an annualized base rate over the ~3 remaining years.

# Current state Kalshi's KXTRUMPRESIGN market prices "Yes" (Trump resigns before Jan 2029) at 20¢, drifting slightly upward over the past month. Resolution requires an actual resignation — not impeachment, not removal, not a poll showing support for resignation. As of now there is no resignation announcement, no completed impeachment, and no active 25th Amendment process; the market price reflects speculative/tail risk rather than any concrete mechanism in motion. # Timeline of key events - 2025-01-20 (confirmed): Trump inaugurated for second term (2025–2029). - 2025-XX (reported): Trump diagnosed with chronic venous insufficiency (CVI) after leg swelling observed publicly; MRI/CT scan reporting sparks cardiologist/media speculation about undisclosed health issues (cardiovascularbusiness.com, metroveincenters.com). - 2025-12-10 (confirmed): House votes 237–140 to table H.Res.939, a prior impeachment resolution — shows GOP-controlled House blocks removal efforts (yahoo.com). - 2026-04 (confirmed): Rep. John Larson files new articles of impeachment tied to Iran strikes; separately calls for Cabinet 25th Amendment invocation; over 70 House Democrats publicly back impeachment or 25th Amendment action (larson.house.gov) — still far short of votes needed. - 2026-05 (reported): Physician update says CVI-related leg swelling has improved since initial diagnosis (metroveincenters.com). - 2026-08-24 (confirmed): Rep. Al Green files H.Res.1486 to impeach Trump over ICE/CBP conduct allegations (algreen.house.gov). - 2026-XX (reported, undated): Venezuela military action reignites impeachment/removal calls per Time magazine (impeachtrumpagain.org). - 2026-10-10 (confirmed): White House physician Sean Barbabella states Trump "continues to demonstrate excellent overall health" with no schedule restrictions. # Event Will President Trump resign from office before his term ends (Jan 20, 2029)? # Outcomes to forecast Yes / No # Kalshi market anchor **KXTRUMPRESIGN "Before his term ends" — YES currently priced at 20¢.** 7-day change +1pt, 30-day change +2pt (slow upward drift). Average daily volume ~1,060 contracts; 179-day price range 15¢–27¢. This is the consensus to beat. # Sub-question answers 1. **Current Kalshi price/history** — 20¢ YES, trending up modestly (+1pt/7d, +2pt/30d), range 15–27¢ over 179 days, ~1,060 contracts/day volume. [kalshi_direct] 2. **Polymarket equivalent** — No direct Polymarket market exists for "Trump resigns" long-horizon. Closest match, "Trump out as President by August 31 [2026]," priced YES at 0.1% (essentially zero) with $2.6M volume — but this is a short-dated market for a now-passed near-term window, not directly comparable to the full-term question. [polymarket_related] 3. **Historical base rate** — Only 1 resignation (Nixon) in 46 presidencies (~250 person-years) → resignation-only hazard ≈0.4%/yr, implying ~1.2–1.6% over the remaining ~3 years. Combined resignation+death-in-office base rate is much higher (~9/46 terms) implying an upper bound of ~10–15%, but death risk is a different mechanism from voluntary resignation. [code_execution] 4. **Active impeachment/25th Amendment activity** — Multiple impeachment resolutions filed in 2025–2026 (H.Res.939 tabled 237-140 in Dec 2025; Larson's April 2026 filing tied to Iran strikes; Al Green's H.Res.1486 in Aug 2026) — all symbolic, none advancing in the GOP-controlled House. 70+ Democrats have called for impeachment or 25th Amendment invocation, but no Cabinet-led 25th Amendment process exists. [claude_news] 5. **Health status** — White House physician (Oct 10, 2026) reports "excellent overall health," no restrictions. CVI diagnosis confirmed; leg swelling reportedly improved by May 2026. MRI/CT scan reporting fueled speculation but no credible incapacity narrative has emerged. [claude_news, cardiovascularbusiness.com, metroveincenters.com] 6. **Correlated markets** — KXTRUMPREMOVE (impeach AND remove) = 14¢; KXIMPEACH-29-JAN20 (impeached, not necessarily removed, by Jan 2029) = 65¢ and rising (+2pt/7d). These indicate the market sees House impeachment as increasingly likely but conviction/removal or resignation as much less likely (14–20¢ range), consistent with GOP Senate control blocking removal. [kalshi_related] # Key facts (high-confidence, factual) 1. [kalshi_direct] KXTRUMPRESIGN YES = 20¢, up slightly over 30 days. 2. [claude_news] H.Res.939 tabled 237–140 (Dec 10, 2025); GOP majority blocks impeachment. 3. [claude_news] No Cabinet 25th Amendment action has occurred; all invocation talk is rhetorical. 4. [claude_news] White House physician states Trump in "excellent health" (Oct 2026). 5. [code_execution] Nixon is the only U.S. president to resign in 235+ years of the office. 6. [kalshi_related] KXIMPEACH-29-JAN20 (impeachment only) = 65¢; KXTRUMPREMOVE (removal) = 14¢. # Cross-market signals - Kalshi related: Impeachment (not removal) priced much higher (65¢) than removal (14¢) or resignation (20¢) — market sees House impeachment plausible but Senate conviction/resignation unlikely. - Polymarket: Near-zero (0.1%) probability for Trump being "out as president" by Aug 31, 2026, a near-term proxy — consistent with very low near-term resignation risk, though not the full 2029 horizon. - Sportsbook implied: none available. # Analyst opinions and speculation - Growing Democratic messaging around impeachment/25th Amendment (Larson, Markey, Al Green) reflects political pressure, not a credible removal pathway given GOP control of both chambers. - Health speculation (MRI reporting, cardiologist commentary) is largely media-driven; official medical statements contradict incapacity narratives. - News tools note betting markets historically showed impeachment odds climbing over time (18%→66% by Jan 2027/2028), but explicitly caution impeachment ≠ resignation/removal. # Directional lean per outcome - **Yes (resigns):** Weak support — only from tail-risk scenarios (health deterioration, extreme political crisis, Venezuela/Iran escalation backlash). Historical base rate (~1–2%) is far below current 20¢ price, suggesting market may be overpricing tail risk relative to pure resignation history — though political volatility (multiple impeachment filings, rising public support) may justify a premium over historical base rate. - **No (does not resign):** Strong support — GOP-controlled Congress blocks removal, no Cabinet 25th Amendment action, official health reports positive, no resignation signals, only 1 resignation in U.S. history. # Gaps / unknowns - No Polymarket data for the actual 2029-horizon resignation market. - Precise date/details of Venezuela-related renewed impeachment calls unclear. - Unclear how much of the 20¢ Kalshi price reflects genuine health/political risk vs. speculative/low-liquidity market noise (volume is modest, ~1,060/day). # Calibration anchors - Kalshi current YES price: 20¢ (anchor). - Historical base rate for presidential resignation: ~1 in 46 terms (~1–2% over 3 remaining years); combined with death-in-office, upper bound ~10–15%. - Precedent: Only Nixon resigned (1974), amid actual impeachment proceedings advancing with bipartisan support — a materially more severe scenario than current tabled/symbolic resolutions.

1. Both forecasters shade well below the 20¢ Kalshi anchor (to 11% and 15%) using a "low-liquidity tail markets overprice" argument, but neither substantiates this claim with evidence from the brief — the ~1,060 contracts/day volume is modest but not clearly "low-liquidity" enough to justify such a large discount, and the brief itself frames 20¢ as "the consensus to beat," not a known bias. 2. Neither forecast grapples with the ~2.5-year remaining term (through Jan 2029) versus the brief's stated "remaining ~3 years" — Forecast 1 says "~2 years" which understates the horizon and mechanically deflates its own base-rate calculation. 3. Both dismiss health risk too quickly by citing the Oct 2026 "excellent health" statement, but neither addresses that official White House health reports have historically been contested/politicized, nor do they weight the still-unresolved MRI/CT speculation as an independent tail risk beyond CVI. 4. Neither forecaster explicitly reconciles their number with KXIMPEACH-29-JAN20 at 65¢ and rising (+2pt/7d) — a rising impeachment probability, even if impeachment≠resignation, could still signal escalating political crisis conditions that raise resignation odds (as in Nixon's case, resignation followed advancing impeachment), yet both treat impeachment activity as purely reassuring "symbolic/dormant." 5. Both converge tightly (11-15%) without flagging the asymmetry in the base-rate calculation itself: pure resignation hazard is ~1-2%, yet both land 6-10x higher than that reference class purely on "premium for volatility," which is a large, unquantified adjustment that deserves more scrutiny or a wider confidence interval. 6. Neither addresses the scenario where a health-related incapacity is resolved via resignation rather than 25th Amendment (e.g., voluntary step-down for legacy/family reasons distinct from crisis-driven resignation), a plausible alternate pathway to YES not captured by "tail risk = health deterioration or political crisis" framing.

14% (64% confidence)

Yes: 14% No: 86%

The 20¢ Kalshi anchor is the consensus to beat, but it sits ~10x above the pure historical resignation hazard (~1 in 46 presidencies, ~1.5% over the remaining ~2.3 years), and long-dated tail-YES contracts on thinly traded markets carry a well-documented longshot premium. Every concrete mechanism is dormant: H.Res.939 tabled 237-140, Larson/Green filings symbolic in a GOP House, no Cabinet 25th Amendment process, and the Oct 2026 physician report cites excellent health with no restrictions; the near-term Polymarket proxy sits near zero. The critique fairly notes that the 65¢ and rising impeachment market signals escalating crisis conditions (Nixon resigned only once impeachment advanced with bipartisan support), that Trump is 80 with a CVI diagnosis, and that a voluntary/health-related step-down is an under-modeled path to YES — so I do not discount as aggressively as Forecast 1. Balancing the carry-adjusted market signal (~22% implied) against the base rate and dormant mechanisms, I settle at 14%, modestly below the market and between the two forecasts.
