This is a long-horizon leader-exit question on Kalshi about Taiwan's President Lai Ching-te. The key drivers are actuarial base rates for leader exit (death, illness), recall/impeachment mechanics under Taiwan's constitution, political crisis (KMT-TPP legislative majority, budget fights), and cross-strait conflict risk. The Kalshi price is the primary anchor; I'll triangulate with related leader-exit markets and Taiwan invasion markets.

# Current state Lai Ching-te remains in office as Taiwan's president; the only formal removal attempt against him — a KMT/TPP-led impeachment motion — failed in the Legislative Yuan on 2026-05-19 (56-50, far short of the 76-vote/two-thirds threshold required). No resignation, health crisis, or other active removal mechanism is underway; Kalshi currently prices only a 13% chance he leaves office before July 1, 2027. # Timeline of key events - 2024-01-13 (confirmed): Lai Ching-te elected president with 40% of vote [Wikipedia]. - 2024-05-20 (confirmed): Lai inaugurated as 8th President of the ROC [Wikipedia]. - 2025-07/08 (confirmed): "Great Recall" votes against 31 KMT-aligned legislators all fail; opposition also survives DPP-backed recall attempts, leaving legislative balance unchanged [Wikipedia]. - 2025-12 (reported): KMT/TPP announce plan to impeach Lai after he declined to promulgate a local-government tax-revenue-sharing bill [Global Times, CW.com]. - 2026-05-19 (confirmed): Impeachment vote fails 56-50 in Legislative Yuan, well short of the 76-vote (two-thirds) threshold; first-ever presidential impeachment vote in Taiwan's history [Focus Taiwan]. - 2026 (ongoing, reported): Opposition blocks Lai's NT$1.25 trillion (~$40B) military procurement plan for a fourth time; approval ratings recover from sub-30% lows to a DPP-commissioned 56.4% approval / 51.8% trust in a May 2026 poll (partisan source, likely favorable bias) [Focus Taiwan, Taipei Times, stateofthestrait.substack]. - Recent (per Kalshi data pull, ~last 30 days): Market YES price fell from 26% to 13%, consistent with the impeachment failure and stabilizing approval numbers reducing perceived removal risk. # Event Will Lai Ching-te leave office before July 1, 2027 (2:00 PM UTC)? # Outcomes to forecast - Yes (leaves office before close) - No (remains in office through close) # Kalshi market anchor Current YES price: **13%**. 7-day change: -9pts; 30-day change: -9pts (down from a high of 26%). Average daily volume: 257 contracts (thin-moderate liquidity). Price trend indicates market has been de-risking this outcome, likely following the failed May 2026 impeachment vote and recovering approval ratings. # Sub-question answers 1. **Kalshi price/volume/trend?** Current 13% YES, down 9pts over both 7- and 30-day windows (was as high as 26%); ~257 contracts/day average volume [kalshi_direct]. 2. **Legal removal mechanism/threshold, any active effort?** Impeachment requires 76/113 (two-thirds) Legislative Yuan votes plus two-thirds of Constitutional Court justices ruling a constitutional/legal violation; until then president stays in office. One impeachment motion was filed (Dec 2025) and failed 56-50 in May 2026 — opposition (KMT+TPP+2 independents) holds only ~62/113 seats (55%), short of the two-thirds bar [Focus Taiwan, CW.com]. 3. **Base rate for mid-term exit of elected leaders in stable democracies over ~18 months?** No direct empirical figure found in raw research; code_execution model assumes 1-3%/yr resignation/removal hazard for stable democracies as a working base rate. 4. **Lai's age/health, mortality probability over 18 months?** Lai is 66 (b. 1959); no reported health issues. Modeled 18-month survival ~98.5-99% (0.7-1.0%/yr mortality hazard for this demographic) [code_execution]. 5. **Current political crisis state?** KMT/TPP hold a legislative majority but lack the two-thirds supermajority needed for impeachment; both the 2025 "Great Recall" (against KMT) and the 2026 impeachment (against Lai) failed, indicating a stalemate rather than escalating crisis. Legislative gridlock persists (4th blockage of major defense budget) but approval ratings for Lai are recovering [Wikipedia, Focus Taiwan, stateofthestrait.substack]. 6. **Chinese invasion/blockade probability priced by markets before mid-2027?** No direct Kalshi/Polymarket market found for Taiwan invasion in this window; related Kalshi market on US Taiwan travel advisory (Level 4) prices only 0.10%, suggesting markets see near-term cross-strait crisis as very unlikely [kalshi_related]. # Key facts (high-confidence, factual) 1. [Focus Taiwan] Impeachment vote against Lai failed 56-50 vs. 76 needed (2026-05-19). 2. [CW.com] Impeachment requires two-thirds Legislative Yuan + two-thirds Constitutional Court to take effect. 3. [Wikipedia] All 2025 KMT recall attempts failed; opposition retains legislative seats. 4. [Kalshi] Current YES price 13%, down from 26% high, trending down. 5. [code_execution] Lai is 66, no reported health issues. # Cross-market signals - Kalshi related: US Taiwan Level-4 travel advisory market prices near 0% (0.10%), implying markets see acute cross-strait crisis as very unlikely before mid-2026. - Polymarket: No direct Lai/Taiwan market found; comparable "Putin out as President by Dec 2026" prices at 7.5% YES, illustrating similarly low market pricing for incumbent authoritarian-adjacent leader removal (not a perfect comp, as Taiwan is a democracy with fixed term but higher institutional removal friction). - Sportsbook implied: None available. # Analyst opinions and speculation - Focus Taiwan/CW.com analysts note impeachment threshold "deliberately high to prevent abuse," implying future attempts are unlikely to succeed absent a legislative supermajority shift. - stateofthestrait.substack suggests Lai's presidency "may be stabilizing" post-impeachment-failure, reducing near-term political exit risk. # Directional lean per outcome - **Yes (leaves office):** Supported only by residual mortality/tail risk and low-probability war/regime scenarios; no active credible removal mechanism exists post-May 2026 impeachment failure. - **No (remains in office):** Strongly supported — opposition lacks two-thirds supermajority, recall efforts have failed on both sides, approval ratings recovering, no health issues reported, Kalshi price declining toward this outcome. # Gaps / unknowns - No hard empirical historical base rate cited for mid-term exits in comparable presidential democracies (assumption-based only). - GDELT news tool failed (timeout) — recent 2026 H2 developments post-dataset may be missing. - No explicit invasion/blockade probability market found for this specific window. # Calibration anchors - Kalshi current YES price: 13% (anchor). - Precedent: Impeachment attempt already failed by wide margin (56-50 vs 76 needed) in May 2026 — no new legislative shift reported since. - Comparable Polymarket precedent (Putin exit by Dec 2026): priced at 7.5%, in a lower-institutional-friction political system.

1. Both forecasters converge tightly (7-10%) below the 13% Kalshi anchor, but neither addresses why the market itself might be mispriced too high—if fundamentals (impeachment math, health, no crisis) so strongly argue for <10%, the brief's thin liquidity (~257 contracts/day) should be flagged as a reason the anchor is noisy/unreliable rather than just "discounted." 2. Neither forecast seriously grapples with sub-question 6 (cross-strait invasion/blockade risk) beyond citing the 0.10% travel-advisory proxy; this proxy measures acute crisis advisory issuance, not a Chinese military action severe enough to remove Lai (e.g., assassination, coup, forced exile), which could be a distinct, unpriced tail scenario over an 18-month window. 3. Both treat resignation risk as negligible, but the brief's Political base-rate answer (1-3%/yr resignation/removal hazard "for stable democracies") was never reconciled with Taiwan's unique context—recurring legislative gridlock, budget blockages, and a historic first impeachment vote suggest elevated political stress that could motivate voluntary resignation or new removal tactics (e.g., a second impeachment attempt, snap constitutional crisis) not captured by a generic base rate. 4. Neither forecast discusses the possibility of a shift in legislative composition before mid-2027 (e.g., by-elections, defections, or a second "Great Recall" wave) that could move the opposition closer to the two-thirds threshold; the brief only cites the failed 2025 recalls without addressing whether future recall/by-election cycles remain possible within the forecast window. 5. Both forecasts round down from the 13% anchor to nearly identical figures (7% and 10%) without much daylight between them despite ostensibly independent reasoning, suggesting anchoring bias to each other's plausible range rather than fully independent stress-testing of tail scenarios (health shock, coup, cross-strait escalation, unexpected resignation for other reasons like corruption scandal—none of which are discussed at all in either rationale). 6. Neither rationale explicitly incorporates the Polymarket "Putin exit" comparator's caveat that Taiwan has "higher institutional removal friction," which should arguably push their estimates further below the Putin 7.5% comp than they already are, yet Forecast 2's 10% sits above that comparator despite Taiwan being structurally harder to remove a leader from.

7% (70% confidence)

Yes: 7% No: 93%

The only formal removal path — impeachment — already failed decisively (56-50 vs. 76 needed) in May 2026, and the KMT/TPP bloc (~62/113) is structurally far short of the two-thirds Legislative Yuan threshold plus the additional two-thirds Constitutional Court requirement, so no credible mechanism is live within the ~13-month window. Pure hazard components are small: ~1% mortality for a healthy 66-year-old over 18 months, a modest voluntary-resignation/scandal tail (~1-2%), and a genuinely unpriced but low cross-strait catastrophe tail the critique correctly flags (~1%), plus a small allowance for legislative shifts via by-elections/defections enabling a second, successful impeachment (~1%). That sums to roughly 4-5%, meaningfully below Kalshi's 13% on thin (~257 contracts/day) volume where the anchor is noisy and the price is still trending down (-9pts over both windows). I weight fundamentals heavily but do not fully discard the market, settling at 7% — consistent with both forecasters and below the Putin comparator, appropriately given Taiwan's higher institutional removal friction.
