74% — the median of 6 frontier models, resolving by 2026-11-29.

Answer

Gemini (Google): 78% — Incumbent Taipei mayors running for re-election almost always win, aided by Taipei's structurally pan-blue voting base. Three of the last four Taipei mayors secured second terms, and Chiang maintains solid approval ratings with no major corruption stains. TPP vote share has collapsed following Ko Wen-je's legal troubles, leaving the anti-Chiang vote fragmented and unable to cross 45%. Only a unified DPP-TPP coalition candidate or an unforeseen municipal catastrophe before November 2026 could derail his re-election.

Answer

Claude (Anthropic): 62% — Hinges on whether KMT unity and Chiang's incumbency edge hold against a unified DPP/opposition challenge. Incumbent mayors in Taipei have historically strong reelection odds, and Chiang has maintained moderate approval ratings through his first term. DPP has struggled to find a strong, unifying challenger in Taipei, though scandals or a strong single opposition candidate could shift the race. Election is just one month away with campaigning well underway, limiting time for major shifts in dynamics before Nov 28, 2026.

Answer

GPT (OpenAI): 69% — The race turns on whether a unified opposition can field a credible challenger against an incumbent in Taipei’s blue-leaning electorate. Chiang must secure KMT renomination and then win on November 28; no runoff means opposition vote-splitting is decisive. Taipei has usually favored KMT-aligned mayors, and incumbency plus Chiang’s 2022 win give him a meaningful starting edge. A DPP–TPP coordination deal or a major late polling collapse for Chiang would materially lower these odds.

Answer

Grok (xAI): 62% — Incumbent plurality win holds if DPP/TPP stay split one month out. Chiang must simply outpoll the field on 28 Nov; no runoff exists and 2022 already showed 42% suffices when opposition fragments. Taipei incumbents re-elect at mixed rates (Ko twice, Ma once) but KMT holds the machine and no scandal has surfaced by late Oct. A late DPP-TPP joint ticket or a 5-point polling collapse would flip it; neither is priced in yet.

Answer

DeepSeek (DeepSeek): 93% — An incumbent KMT mayor of Taipei with no serious challenger and a 30-point polling lead is about as safe as Taiwanese politics gets. Chiang won in 2022 with 57.6% against a divided pan-green field, and no credible KMT primary challenger has emerged for 2026. The DPP has not fielded a heavyweight; Taipei's pan-blue structural advantage (roughly 55-45 in recent citywide races) makes a flip require a national wave. The one thing that would move this: a major corruption indictment or a KMT split candidacy before the November 28 vote, neither of which is currently visible.

Answer

Qwen (Alibaba): 79% — Incumbent Taipei mayors have won re-election every cycle since direct elections began; Chiang faces no known crisis. Every directly elected Taipei mayor (Ma, Hau, Ko) won a second term; incumbency advantage in this city is near-decisive. Chiang's approval has hovered in the mid-to-high 50s through 2025–26, and the DPP has not fielded a candidate polling above ~30%. A sudden scandal or cross-blue defection in the final month would be the main threat, but with 31 days left that window is very narrow.
