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.The Democratic Party of Korea's confirmation of Chong Won-oh as its Seoul mayoral nominee on April 9, after securing over 50% in the primary vote without a runoff, has driven trader consensus to imply an 88.5% probability of victory in the June 3 election, reflecting the ruling party's organizational strength and his three-term Seongdong-gu district leadership. Incumbent Mayor Oh Se-hoon, seeking People Power Party renomination, holds 7.5% as a leading contender amid the main opposition's ongoing three-way primary debates, with recent polls suggesting a tight general matchup but markets favoring the confirmed challenger. Remaining candidates trail due to unresolved party primaries, with campaign momentum and voter turnout in battleground districts key ahead of the direct popular vote.
