Trader consensus strongly favors Chong Won-oh at 78.5% implied probability for the 2026 Seoul mayoral win, driven by his dominant performance in Democratic Party nomination polls, where he captured over 60% support in recent first-round surveys amid Seoul's left-leaning electorate. Incumbent Oh Se-hoon, at 13.5%, benefits from his 2022 special election victory and policy continuity on housing and transit but contends with ruling People Power Party's sagging national approval. Park Ju-min's 7.8% reflects niche progressive backing as a potential alternative. Latest July Democratic primary results boosted Chong's lead, with runoff votes expected soon potentially influencing broader general election odds.
