Michigan's November 3, 2026 ballot is dominated by open seats: Gov. Gretchen Whitmer is term-limited, Sen. Gary Peters is retiring, and Attorney General Dana Nessel and Secretary of State Jocelyn Benson are also term-limited. All 13 US House districts and both state legislative chambers are up as well. Most nominees will be chosen in Michigan's open primary on August 4, 2026; attorney general and secretary of state candidates are instead nominated at party conventions. This Prediction Edge hub connects live market odds with candidate pages, polling context, official election dates, and market-moving updates for every tracked Michigan race.
Gov. Gretchen Whitmer is term-limited, leaving Michigan's governorship open in 2026. Markets track the August 4 Democratic and Republican primaries alongside the November general election in a state both parties treat as a core battleground.
Sen. Gary Peters' retirement opens Michigan's Class 2 Senate seat in 2026. Markets cover the Democratic nomination contest and the November general election, one of the cycle's most closely watched open-seat Senate races.
All 13 Michigan US House seats are on the 2026 ballot. Markets track nomination fights in metro Detroit districts, including the open 10th District, where Rep. John James is leaving to run for governor.
Attorney General Dana Nessel is term-limited, putting Michigan's top law-enforcement office on the 2026 ballot as an open seat. Unlike most races, attorney general nominees are chosen at party conventions rather than the August primary.
