Important information: The contract is settled by counting the number of seats held on Feb 1, 2025. If a seat has been vacated and is still empty on that date, it will not count towards this number.







This market will expire the February 1 following the election, or the next date that data is available. Independents caucusing with a party will count for that party (e.g. Bernie Sanders will count if he caucuses with the Democrats on that date).
