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.Trader consensus heavily favors Chong Won-oh at 81.5% implied probability for the June 3, 2026 Seoul mayoral election, driven by a fresh News1 poll released April 1 showing him leading incumbent Oh Se-hoon 42.6% to 28.0%—widening from prior surveys like February's 47.5%-33.3% gap. As the Democratic Party frontrunner who advanced past the March 24 preliminary primary alongside Jeon Hyun-heui and others, Chong benefits from the party's historical strength in Seoul amid favorable national trends. Oh Se-hoon, seeking a third term under People Power Party banner after March 17 registration, trails in head-to-head matchups while fending off primary challengers like Park Ju-min (5.6%) in recent debates marked by internal tensions and court scrutiny on party nominations. Final primaries and campaign momentum ahead of election day could shift dynamics.
