This market will resolve according to the outcome of both the Gubernatorial and United States Senate general elections in Michigan that are currently scheduled for November 3, 2026. A candidate will be considered to represent a party by their ballot-listed affiliation or if they are the nominee of that party. 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. If the results of these elections are not conclusively known by March 31, 2027, or if an independent or third-party candidate wins one of these elections, this market will resolve to "Other". For purposes of this market, a "sweep" is when a party wins both races. The resolution source for this market is the Associated Press, Fox News, and NBC. This market will resolve once all three sources have conclusively called the relevant Senate and Gubernatorial elections. If all three sources do not achieve consensus in calling the relevant races for this market, it will resolve based on the official certification. Michigan's open U.S. Senate seat and governorship both head into the November 2026 general election after August 4 primaries produced competitive nominees. Abdul El-Sayed secured the Democratic Senate nod in a close contest against Haley Stevens, while Mike Rogers advanced unopposed on the Republican side for the seat vacated by Gary Peters. On the gubernatorial side, Jocelyn Benson won her party's primary decisively to succeed term-limited Gretchen Whitmer, and John James captured the Republican nomination. Recent polling shows the Senate matchup as a toss-up and the governor's race with a modest Democratic edge, reflecting Michigan's swing-state dynamics, divided electorate, and the absence of incumbents. These factors sustain balanced probabilities across combination outcomes, with separation likely hinging on fall campaign momentum, national midterm conditions, fundraising, and turnout patterns in battleground areas.
