Description

These markets track the total number of Senate seats held by the Republican Party following the 2026 midterm elections, as counted on February 1, 2027. Each market corresponds to a specific seat count or range, allowing traders to bet on the exact partisan composition of the Senate after the election.

Kalshi

The Republican Party's Senate seat count on February 1, 2027 will be measured to determine resolution across all markets in this event. Each market resolves to Yes if the Republican Party holds the exact number of seats specified in that market's outcome label, or falls within the specified range for markets covering below 45 seats or above 57 seats. The seat count includes all Republicans and Republican-aligned independents who caucus with the party. Resolution is based on the official composition of the Senate as of February 1, 2027, following the completion of the 2026 midterm elections and any subsequent changes to Senate membership through that date.
