Will the Republicans win the Michigan Senate race in 2026?

The Republican Michigan Senate contract is pricing in a heavily Democratic-favored race at 19¢, with an extraordinarily high implied yield of 778.3% on the Yes side suggesting severe underpricing relative to historical Republican competitiveness in the state. The 7-day price movement from 16¢ to 19¢ indicates recent Democratic momentum, though the $203.9 daily volume against $41k open interest reveals thin liquidity that could amplify volatility as we approach the 2026 election. The 4/10 Cliff Risk Index warrants caution, as binary outcomes in Senate races can shift sharply on candidate quality, national environment, or late-breaking events.

Resolution rules

This market will resolve according to the winner of the 2026 midterm Michigan U.S. Senate election, inclusive of any run-offs. 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.
