5% — the median of 6 frontier models, resolving by 2026-11-29.

Answer

Gemini (Google): 2% — Incumbent Chiang Wan-an holds deep structural advantages in Taipei, where the DPP is structurally disadvantaged and Shen lacks broad appeal. Taipei leans Pan-Blue, making unseating a popular KMT incumbent like Chiang Wan-an an exceptionally high hurdle for any DPP candidate. Shen is a polarizing DPP legislator known primarily for civil defense and civil society, not the executive or moderate profile Taipei favors. DPP primary polling routinely prioritizes higher-profile figures like Lin Chia-lung or Cheng Li-chun over Shen for mayoral nomination.

Answer

Claude (Anthropic): 5% — Taipei mayoral race likely dominated by KMT/TPP/DPP established figures, not Puma Shen specifically. Puma Shen is a DPP legislator known for anti-infiltration work, not a confirmed frontrunner for Taipei mayor nomination. Taipei has leaned KMT/TPP in recent cycles and DPP nominee faces uphill battle regardless of candidate. No strong public polling or party confirmation currently places Shen as the leading candidate for this specific race.

Answer

GPT (OpenAI): 7% — His path depends on unifying non-KMT voters while overcoming Taipei's entrenched KMT advantage in a one-round race. Taipei has elected KMT mayors in every contest since 1998 except Ko Wen-je's 2014 and 2018 victories. Shen must first secure a major-party nomination or credible coalition; candidate registration and campaign consolidation are imminent. A KMT split or a late, unified anti-KMT ticket would materially raise his chances, but such upsets are uncommon in Taipei.

Answer

Grok (xAI): 8% — Turns on whether Shen is even the DPP nominee and can unseat incumbent Chiang Wan-an. Candidate lists and nominations closed well before Oct 2026; Chiang is the sitting KMT mayor seeking re-election. Taipei has elected a DPP mayor only once since 1994 (Chen 1994); recent polls and 2022 results favor KMT. A late poll surge or Chiang scandal would shift this, but none is reported one month out.

Answer

DeepSeek (DeepSeek): 2% — Puma Shen is not a declared candidate for Taipei mayor, and no credible path exists for him to win in four weeks. Taipei's mayoral race is between incumbent Chiang Wan-an and DPP challenger, with Shen not among declared candidates as of late October 2026. Shen is a cybersecurity/defense commentator and DPP figure, not a Taipei political operator with a local base or party nomination. Base rate for a non-candidate winning a major-party-dominated mayoral race weeks before the vote is near zero; only a dramatic last-minute draft would change this.

Answer

Qwen (Alibaba): 5% — Taipei is structurally KMT-leaning and Chiang Wan-an holds incumbency advantage; even as DPP nominee, Shen faces steep odds. Chiang Wan-an entered the race as a popular incumbent with approval ratings consistently above 50% through 2026. No DPP candidate has won Taipei mayor since Chen Shui-bian in 1998; the city's pan-blue lean is ~10 points in normal conditions. A major scandal or cross-strait crisis shifting the electorate would be needed to close that gap in one month.
