Wi Seong-gon secured the Democratic Party nomination and entered the June 3, 2026, Jeju gubernatorial race with a commanding polling advantage over People Power Party nominee Moon Sung-yu and independents. Exit polls and final vote tallies confirmed his victory with roughly 63 percent support, consistent with the Democratic Party's broader sweep in the nationwide local elections. Traders have priced this outcome at near-certainty, reflecting the absence of viable challengers, established party momentum in the province, and the completed ballot count. Late developments such as a major scandal or recount could theoretically alter resolution, though none have emerged to shift the confirmed results.
