Why traders follow Michigan

Michigan's open Senate seat is one of the individual contests feeding into the national balance of power. This page shows the market for the state winner; it is not itself a Senate-control contract. The prices can respond to candidate developments, polling and changes in the order book, so use the live board for the latest available quote.

How to compare the Michigan markets

Look at which outcome is being priced, whether the contract names a person or a party, and whether the quoted price is current and available to buy. Read the exchange's written settlement and runoff provisions before placing an order. The prices shown here express what traders are willing to pay, not a DeFi Rate race rating. For context, see our midterm odds hub and Senate races board.

Michigan Senate election questions

Does the Michigan winner determine Senate control?

No. It determines one seat. The full Senate balance also depends on the results in other states.

Why can the favorite change?

Market prices change as traders revise their orders or new information arrives. A favorite is not a guaranteed winner.
