Two Republican Senate incumbents—John Cornyn of Texas and Bill Cassidy of Louisiana—have already lost renomination amid primary challenges from more conservative opponents, including Attorney General Ken Paxton in Texas and Representative Julia Letlow in Louisiana. With roughly 20 Republican-held seats contested in the 2026 cycle and several additional primaries still scheduled through late summer and fall, traders assign an implied 79% probability to exactly one further defeat for a total of three. This positioning reflects the limited number of viable intra-party contests that have materialized so far, combined with the structural advantages most incumbents retain in low-turnout primaries. A modest probability remains priced for four or more losses if additional high-profile challenges intensify before remaining filing deadlines and voting dates close.

The 2026 midterm elections are scheduled to be held on November 3, 2026, with congressional primaries running from March through September.
This market will resolve according to the number of Republican Senate incumbents who do not win their nominating election to move on to the general election as a result of the 2026 midterm primary elections.
An incumbent will be considered not to have won their election if they are not declared the winner of the election they sought, including if they withdraw, suspend, or otherwise leave the race at any point after officially registering as a candidate, regardless of the reason. Incumbents who do not officially register as candidates for reelection will not be considered.
This market will resolve based on the results of all Senate nominating elections, including party primaries, top-two or jungle primaries, and primaries for special elections, that are scheduled to occur between March 1 and September 30, 2026. If a required runoff for any such election or a subsequent qualifying round in a non-partisan primary system could change the market’s outcome, the market will remain open until that contest is conclusively called by this market’s resolution sources.
A candidate's party will be determined by their ballot-listed or otherwise identifiable affiliation with that party at the time of their nominating election. A candidate without a ballot-listed affiliation to either the Democratic or Republican parties will be considered a member of one of these parties based on the party with which they most recently expressed their intent to caucus prior to the conclusion of the relevant nominating election.
The resolution source for this market will be the Associated Press, Fox News, and NBC. This market will resolve once all three sources have conclusively called all relevant nominating elections. If all three sources do not achieve consensus in calling the relevant races for this market, it will resolve based on official state certification of the nominating election results.Two Republican Senate incumbents—John Cornyn of Texas and Bill Cassidy of Louisiana—have already lost renomination amid primary challenges from more conservative opponents, including Attorney General Ken Paxton in Texas and Representative Julia Letlow in Louisiana.
