The 2026 Seoul mayoral election is scheduled to take place on June 3, 2026 to elect the next mayor of Seoul. This market will resolve according to the listed candidate that wins this election. If the result of this election isn't known by January 31, 2027, 11:59 PM ET, the market will resolve to "Other". This market will resolve based on the result of the election as indicated by a consensus of credible reporting. If there is ambiguity, this market will resolve based solely on the official results as reported by the South Korean government, specifically the National Election Commission.Chong Won-oh's decisive win in the Democratic Party's Seoul mayoral primary on April 9, securing over 50% of votes to bypass a runoff, has propelled him to 89% trader consensus as the June 3 election favorite, reflecting skin-in-the-game bets on his momentum as former Seongdong District mayor amid Democratic advantages in Seoul. Incumbent Oh Se-hoon, confirmed as the People Power Party nominee just yesterday after internal competition, trails at 7.5%, with polls showing a tight head-to-head but markets diverging to price in progressive turnout and Chong's grassroots appeal. Other candidates linger below 1% post-primaries, as the race narrows to the two-party matchup ahead of intensive campaigning.
