Chiang Wan-an maintains a strong lead in the Taipei mayoral market at 81 percent implied probability due to his incumbency as the KMT mayor, established name recognition, and historical KMT advantages in the capital. Recent September polling shows the race tightening sharply, with Chiang at 41.7 percent support and DPP challenger Puma Shen at 40.5 percent—within the margin of error—after earlier surveys had shown Chiang ahead by double digits. Cross-tabulations indicate older voters and women lean toward Chiang while younger voters and men favor Shen, yet traders appear to weigh structural factors such as party registration advantages and lower support for minor candidates like Kuo Hsi. The November election timing leaves room for further shifts in turnout or late developments.
