With primaries on August 4, trader consensus heavily favors a Democratic victory in Michigan's open gubernatorial race, where term-limited Gov. Gretchen Whitmer leaves a contested field. Recent Emerson College polling (April 11-13) solidifies Secretary of State Jocelyn Benson as the Democratic frontrunner at 52%, bolstered by strong fundraising ($5.7 million raised) and endorsements from state legislators and labor unions like the Teamsters. The Republican primary remains fragmented, with U.S. Rep. John James at 20% and businessman Perry Johnson at 21% amid 39% undecideds, signaling potential nominee weakness. General election matchups show competitive three-way races including independent Mike Duggan, but historical Democratic dominance in statewide offices—despite Trump's 2024 presidential win—underpins the 66.5% implied probability for Democrats versus 16.5% for Republicans.

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.
