Trump-aligned challenges and redistricting have already produced four confirmed Republican House primary defeats in 2026, including Dan Crenshaw in Texas and Thomas Massie in Kentucky, where presidential endorsements targeted perceived insufficient loyalty on spending and foreign policy votes. Additional losses by Andy Ogles in Tennessee and Cory Mills in Florida stemmed from scandals and finance issues rather than ideological tests. With primaries largely concluded or in final stages across most states, trader consensus on the 4-6 range reflects the historical rarity of widespread incumbent defeats absent a national wave or redistricting cycle. Remaining contests could add losses if late scandals or surprise Trump interventions materialize, though most sitting members face limited opposition.

This market will resolve according to the number of Republican House 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 House 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.
Members of the House of Representatives who are "delegates” or “resident commissioners” not chosen by the people of a state are not included for purposes of resolving this market.
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.
