Trader consensus on Polymarket favors self-funding businessman Perry Johnson at 48.5% to win the Michigan Republican gubernatorial primary on August 4, ahead of U.S. Rep. John James at 33%, driven by Johnson's recent polling momentum and aggressive ad spending amid a fragmented field. An April 16 Emerson College survey showed a dead heat (Johnson 21%, James 20%), while the April 25 Glengariff Group poll had James leading 37-20%, highlighting volatility with high undecideds (up to 39%). Johnson's prior statewide run and financial edge position him strongly in this low-turnout primary, though James benefits from name recognition as a combat veteran and job creator. Markets diverge from polling averages, emphasizing Johnson's potential late surge as filing deadlines passed April 21.

If no 2026 Michigan Gubernatorial Republican Primary takes place, this market will resolve to “Other.”
The resolution source for this market will be the first official announcement of the results from the Michigan Republican Party; however, an overwhelming consensus of credible reporting may suffice.
