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 commanding 86.5% implied probability in the 2026 Seoul mayoral election market stems from his April 9 confirmation as the ruling Democratic Party of Korea's nominee, securing over 50% in the primary against rivals Park Ju-min and Jeon Hyun-heui to advance directly to the June 3 ballot without a runoff. Recent polls, such as News1's showing him at 42.6% versus incumbent Oh Se-hoon's 28%, bolster trader consensus on his edge in this high-stakes local race testing President Lee Jae-myung's administration. The opposition People Power Party faces internal clashes over its candidate selection, keeping Oh Se-hoon at 8.5% as the main alternative amid low odds for others; upcoming primaries and debates could shift dynamics before early voting.
