Trader consensus prices one Republican Senate incumbent not winning their primary at 37.5%, with two close behind at 28%, driven by high-stakes challenges to Sens. John Cornyn in Texas and Bill Cassidy in Louisiana. Recent University of Houston polling from May 5 shows Attorney General Ken Paxton leading Cornyn by three points ahead of the May 26 GOP runoff, amplified by Cornyn's deleted repost of anti-Trump content on May 10 and absent presidential endorsement. Cassidy trails Rep. Julia Letlow and others in Louisiana's May 16 Republican primary per prediction markets and activist calls from Scott Presler on May 14, tied to his 2021 impeachment vote. Other incumbents like Susan Collins face nominal opposition with strong polling edges. Trump endorsements, final debates, or turnout surges could tip these contests, clarifying the total.

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.
