What is this event about?

This market will resolve according to the winner of the Republican Primary for Governor of Michigan, scheduled to take place on August 4, 2026. Resolution will be based on the overall winner of the primary, including any potential second round or run-off. 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.
