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 official voter turnout rate for the 2026 Seoul mayoral election, defined as the total number of votes cast (총투표자수) divided by the total number of registered voters (선거인수). If the reported value falls exactly between two brackets, this market will resolve to the higher bracket. If the results of this election are not definitively known by January 31, 2027, 11:59 PM ET, this market will resolve to the lowest bracket. This market will resolve based on the official results as reported by the South Korean government, specifically the National Election Commission (https://info.nec.go.kr/).High early voting participation ahead of the June 3, 2026, South Korean local elections produced a preliminary official turnout of 61 percent for the Seoul mayoral contest, placing it squarely in the 60-65 percent band that now commands near-certain trader consensus. The competitive nature of the race between incumbent Oh Se-hoon of the People Power Party and his Democratic Party challenger mobilized voters, building on elevated engagement seen in recent national contests and yielding the second-highest local-election participation rate on record. Historical patterns for Seoul mayoral races, combined with the absence of major weather or logistical disruptions on election day, reinforced expectations around this range. Only late revisions to the final certified figure or unforeseen counting anomalies could shift resolution outside 60-65 percent.
