This market will resolve according to the winner of the 2026 midterm Maine U.S. Senate election, inclusive of any run-offs. A candidate shall be considered to represent a party in the event that he or she is the nominee of the party in question. Candidates other than the Democratic or Republican nominee (e.g., Greens, Libertarian, independent) may be added at a later date. Candidates who run as independents will not be encompassed by the “Democrat” or “Republican” options regardless of any affiliation they may have with the party. The resolution source for this market is the Associated Press, Fox News, and NBC. This market will resolve once all three sources call the race for the same candidate. If all three sources haven’t called the race in this state for the same candidate, this market will resolve based on the official certification.
Democratic nominee Troy Jackson holds a clear edge in trader consensus for the 2026 Maine Senate race, driven by recent polling showing him leading or tied with incumbent Susan Collins and the swift unification of Democratic support after his late-July selection at a nominating convention. Jackson, a former state Senate president with strong labor and rural backing, replaced the prior nominee following withdrawal amid allegations, allowing focused messaging on issues including abortion rights and Collins' long record. Recent surveys highlight narrow leads for Jackson among likely voters and heightened scrutiny of Collins' positions, though the race remains competitive with the November 3 general election still months away and voter turnout patterns in this swing state undecided.
