Trader consensus heavily favors Chong Won-oh at 79.5% implied probability to win the 2026 Seoul mayoral election, driven by recent Democratic Party (DP) internal surveys and his rising profile as a potential nominee amid Oh Se-hoon's incumbent challenges. Oh Se-hoon, the current People Power Party mayor, holds 12.5% on his track record of urban development wins, but faces fatigue after multiple campaigns and DP momentum post-2024 legislative gains. Park Ju-min's 7.1% reflects niche progressive support. Low odds for others like Ahn Cheol-soo signal no viable challengers yet. Key catalysts include upcoming DP primaries and national polls; watch Q1 2025 candidate announcements for shifts.
