Planner reasoning

The KMT won 13 of 22 local executive seats in 2022 and has a deep structural advantage in local elections (incumbency, local factions, small-county dominance in Hualien/Taitung/Kinmen/Lienchiang etc.), so the base rate strongly favors YES. Key uncertainties are the post-2025 recall-wave political climate, new KMT chair Cheng Li-wun's popularity, KMT-TPP blue-white cooperation, and whether the market price already reflects near-certainty. Research should anchor on the Polymarket price, then gather 2022 baselines, current party support polling, and Taiwanese political news.

# Current state KMT enters the November 28, 2026 elections defending a 13-seat plurality (of 22) from 2022, with structural strongholds (Kinmen, Lienchiang, Miaoli, Taitung, Nantou, Hualien, New Taipei, Taichung) giving it a durable base. The party has nominated candidates in 19 of 21 races, ceding Hsinchu City and Chiayi City to TPP allies under a blue-white cooperation pact. No votes have been cast; resolution depends entirely on the Nov 28, 2026 official results. # Timeline of key events - 2022-11-26: KMT wins 13 of 22 head-of-government seats, DPP 5, TPP 1, independents 2 (confirmed, Wikipedia/Focus Taiwan). - 2025-07-26 & 2025-08-23: Mass recall campaigns targeting KMT legislators fail in both waves; several KMT legislators outperform their 2024 election vote totals (confirmed, Wikipedia/ECCT). - 2025-10-18: Cheng Li-wun elected KMT chairperson, defeating Hau Lung-bin; pledges fair nominations and youth renewal ahead of 2026 (confirmed, Focus Taiwan). - 2026-03: KMT and TPP agree in principle to use joint polling primaries for New Taipei mayor, Chiayi City mayor, and Yilan magistrate (confirmed, Taiwan News, 2026-03-18). - 2026-03 (reported): TPP founder Ko Wen-je sentenced, weakening TPP's standalone capacity and reinforcing alliance with KMT (reported, claude_news synthesis). - 2026-04-07: TPP's Chang Chi-kai wins joint opposition primary for Chiayi mayor over KMT's Weng Shou-liang (confirmed, Taiwan News). - 2026-07-25: KMT confirms nominees in 19 of 21 races, standing aside in Hsinchu City and Chiayi City for TPP (confirmed, Focus Taiwan). - 2026-07-19–08-14: Multiple analyses (Taipei Times "Donovan's Deep Dives") describe competitive races in central Taiwan, northern Taiwan, and "KMT eyes southern upsets" while DPP faces internal disarray (reported, Taipei Times). - 2026-08-14: Legislature (opposition-controlled) approves 3 referendum questions to run alongside the local elections (confirmed, Focus Taiwan). # Event Will KMT's official nominees win the most head-of-government (mayor/magistrate) races among the 22 listed Taiwan municipalities/counties in the Nov 28, 2026 elections? # Outcomes to forecast - Yes (KMT wins plurality) - No (another party, incl. DPP, wins plurality or ties broken against KMT) # Kalshi market anchor No Kalshi-direct price returned in this dataset; Kalshi's own related markets (Taiwan presidential winner, etc.) are the only comparables and don't directly price this event. Treat the Polymarket figure below as the primary cross-market anchor. # Sub-question answers 1. **2022 breakdown / current KMT holdings** — KMT 13, DPP 5, TPP 1, independents 2 of 22 seats (Wikipedia; Focus Taiwan); KMT currently holds all 13 as incumbents entering 2026. 2. **Historical base rate** — KMT won pluralities in 2018 (15 seats) and 2022 (13-14 seats); DPP's only recent plurality was in earlier cycles pre-2018 when it held 13/22 (2014-2018 term), but suffered a landslide reversal in 2018 tied to national dissatisfaction with Tsai administration (Wikipedia). 3. **2025-2026 polling** — Direct KMT/DPP/TPP generic polling not surfaced in research; proxy evidence (failed 2025 recalls, "majority support government; few back legislature" July 2026 poll, Taipei Times) suggests DPP administration retains majority approval but legislature (opposition-led) less trusted — mixed signal, no clean party-preference number found. 4. **Cheng Li-wun leadership & blue-white cooperation** — Cheng elected KMT chair Oct 2025 pledging fair primaries/youth renewal (Focus Taiwan); KMT-TPP agreed March 2026 to joint primaries in New Taipei, Chiayi City, Yilan; TPP won Chiayi nomination April 2026; KMT stood aside in Hsinchu City and Chiayi City for TPP by July 2026 — reduces vote-splitting risk in those races (Taiwan News, Focus Taiwan). 5. **Open/term-limited seats** — New Taipei, Taichung, Tainan, Kaohsiung mayors term-limited out (Taipei Times, 2024/2026 "Deep Dives" series); Taipei and Taoyuan incumbents (KMT) seeking re-election. Central Taiwan (Taichung) and southern races (Tainan, Kaohsiung) flagged as most competitive/contested in Aug 2026 Taipei Times analyses. 6. **Minimum plausible KMT floor & DPP ceiling** — Monte Carlo simulation (code_execution) using 2022 margins: baseline mean ~13.7 KMT seats vs 6.5 DPP; strongholds (Kinmen +35, Lienchiang +40, Miaoli +30, Taitung +28, Nantou +25 margin) give KMT floor near 10-11 even under severe swings; DPP needs ~10+ point uniform national swing to approach parity, beyond any swing seen 2018-2022. 7. **Polymarket price/trend** — Current 92.5% YES (up from 80% low over 90 days; +5% over 7 days, +6.5% over 30 days), volume $58,201; earlier reporting cited 81-88 cents in this same market family (claude_news), suggesting recent upward re-pricing toward KMT. # Key facts (high-confidence, factual) 1. [Wikipedia] KMT holds 13/22 seats since 2022; DPP 5, TPP 1, ind. 2. 2. [Focus Taiwan, 2026-07-25] KMT nominated in 19/21 races, deferring Hsinchu City/Chiayi City to TPP. 3. [Focus Taiwan, 2025-10-18] Cheng Li-wun is KMT chair since Oct 2025. 4. [Wikipedia] All 2025 recall attempts against KMT legislators failed (both waves). 5. [code_execution simulation] KMT retains >50% win probability even under a hypothetical 13-15 point anti-KMT swing. # Cross-market signals - Kalshi related: No direct Taiwan-local-election market found; only Taiwan presidential (Lai 60%) and unrelated markets. - Polymarket: 92.5% YES, up from 80% low (90-day range), +6.5% over 30 days, modest volume ($58K) — thin but consistently rising toward KMT. - Sportsbook implied: None available. # Analyst opinions and speculation - Taipei Times "Donovan's Deep Dives" series (Jun-Aug 2026) frames central/southern races as genuinely contested, with "KMT eyes southern upsets" while DPP faces internal disarray — bullish for KMT beyond its base (reported). - newcongress.tw analysis flags DPP fatigue in the south (land use, housing, infrastructure complaints) as a risk to DPP's remaining strongholds (reported). - claude_news synthesis notes TPP's diminished independent capacity (Ko Wen-je sentencing) reinforces blue-white alliance, reducing three-way vote splitting that could otherwise hurt KMT (reported/inferred). # Directional lean per outcome - **Yes (KMT)**: Strong incumbency (13/22), landslide-margin strongholds, successful 2025 recall defense, blue-white cooperation reducing vote-splitting, rising Polymarket price (92.5%), simulation showing >90% win probability under normal swings. - **No (DPP/other)**: DPP could gain if a substantial (8-10+ pt) national anti-incumbent-opposition or anti-KMT swing materializes, or if term-limited open races (Taichung, Tainan, Kaohsiung, New Taipei) break unfavorably; DPP retains national government incumbency which could cut either way. No concrete recent DPP-favorable polling surfaced. # Gaps / unknowns - No granular 2025-2026 generic party-preference (KMT vs DPP vs TPP) poll numbers were retrieved despite being requested. - No Kalshi-direct YES price was returned for this specific ticker in the tool output. - Candidate-level competitiveness in the four open term-limited races (New Taipei, Taichung, Tainan, Kaohsiung) not quantified beyond qualitative "contested" framing. # Calibration anchors - Polymarket YES price: 92.5% (current), range 80-92.5% over 90 days, uptrend. - Historical precedent: KMT won plurality in 2018 (15/22) and 2022 (13/22); DPP's last plurality predates 2018 wave loss. - Model-based estimate: ~90-97% KMT win probability under plausible swing scenarios (code_execution simulation).

1. Both forecasts anchor heavily on Polymarket's 92.5% at $58K volume, calling it "modest," but neither discounts sufficiently for the brief's explicit gap: "No Kalshi-direct YES price was returned" and "Candidate-level competitiveness in the four open term-limited races... not quantified beyond qualitative 'contested' framing" — thin liquidity plus unquantified open-seat risk warrants more separation from the market price than the ~1.5-2.5pt shave both apply. 2. Neither forecast grapples with the tie-break/plurality mechanics explicitly flagged in the outcomes definition ("No... incl. DPP, wins plurality or ties broken against KMT") — with KMT contesting only 19 of 21 races and TPP/independents holding several seats, a scenario where KMT and DPP end up tied or where TPP+independents collectively deny KMT an outright plurality lead is under-examined. 3. The Monte Carlo simulation is described as using "2022 margins" as its base case, but both forecasters treat its 90-97% output as near-definitive despite the brief noting DPP retains "majority approval" nationally per a July 2026 poll — a genuine mixed signal on government approval vs. legislature distrust that could translate unpredictably in the four contested open races (Taichung, Tainan, Kaohsiung, New Taipei), yet neither forecast meaningfully widens uncertainty for this. 4. Both cite "failed 2025 recall waves" as bullish for KMT, but neither considers that recall votes and general elections have different turnout dynamics and voter bases — this is a reference-class extrapolation that may overstate transferability to a plurality-of-22-races outcome. 5. Neither forecaster addresses the DPP's national incumbency as a double-edged factor explicitly noted in the brief ("could cut either way") — a competent government approval rating for the DPP administration during a cost-of-living or infrastructure downturn (per "newcongress.tw" southern fatigue analysis) could just as easily produce anti-incumbent backlash against DPP locally as it could a rally effect, and this asymmetry isn't explored. 6. Both converge suspiciously close together (0.93 vs 0.91) and both frame themselves as "slightly below market" with nearly identical hedging language, suggesting anchoring bias on each other's likely reasoning or the same market price rather than independent triangulation from the fundamentals/simulation data alone.

92% (70% confidence)

Yes: 92% No: 8%

KMT's structural position is the dominant driver: it defends 13 of 22 seats, holds several landslide-margin strongholds (Kinmen, Lienchiang, Miaoli, Taitung, Nantou, Hualien) that create a floor near 10-11 seats, and won pluralities in both 2018 and 2022. The DPP would need a ~10-point uniform national swing to reach parity, larger than anything observed in recent cycles, and blue-white cooperation removes the main three-way vote-splitting risk. The critique's points about thin Polymarket liquidity ($58K), unquantified open-seat competitiveness in Taichung/Tainan/Kaohsiung/New Taipei, and the questionable transferability of recall-vote turnout dynamics justify shading a bit below the 92.5% anchor, but even losing all four contested open races leaves KMT with a plurality given DPP's low base of 5. Tie/TPP-denial scenarios are real but narrow, since KMT would need to fall to ~7-8 seats for them to bind. I settle at 0.915 — essentially at the market, with the modest discount reflecting genuine uncertainty about a still-distant vote.
