Michigan's open 2026 gubernatorial race, following term limits on incumbent Democrat Gretchen Whitmer, features Democratic nominee Jocelyn Benson, the sitting secretary of state who secured her party's primary nomination by a wide margin on August 4, against Republican nominee U.S. Representative John James, who prevailed in his primary the same day. Recent polling averages place Benson ahead by roughly 6 points, consistent with Democratic performance in Michigan statewide contests since 2018 and advantages in voter turnout patterns and fundraising. Traders assign the Democratic outcome an 89% implied probability, reflecting the party's structural positioning in this battleground state and the lack of major late-cycle shifts that could alter the trajectory before the November 3 general election.

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.
