Incumbent Democrat Gretchen Whitmer's term limits create an open Michigan gubernatorial race set for the August 4 primary and November 3 general election. Trader consensus prices a Democratic victory at 64% implied probability, driven by party unity around frontrunner Secretary of State Jocelyn Benson, who leads Democratic primary polls by wide margins and secured endorsements from U.S. Rep. Hillary Scholten, the Michigan Nurses Association, and state legislators in March-April. Recent GOP primary surveys (late March 2026) show U.S. Rep. John James' lead eroding to 18-26% as businessman Perry Johnson surges to 17-21% amid high undecideds (44%), fragmenting Republican support and capping their general odds at 21%. February general polls depict a tight three-way contest with independent Mike Duggan, yet markets diverge from slight polling edges for James, factoring Michigan's Democratic trifecta and Whitmer's 50% approval.

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.
