Trader consensus heavily favors 10-12 Democratic House incumbents failing to win renomination, reflecting an above-average primary defeat rate driven by progressive challenges and generational shifts. Multiple losses occurred to democratic socialist or DSA-aligned candidates in New York, Colorado, and Michigan, alongside other upsets tied to age and ideological differences, pushing Democratic defeats to seven by mid-September—matching highs not seen since 2012. Redistricting effects in states like Texas contributed additional member-on-member contests. With most primaries concluded, the 92% probability on 10-12 captures this elevated but contained wave of turnover. Outcomes could shift modestly if late contests or final tallies alter the count, though historical patterns and the near-completion of the primary calendar limit upside risk beyond the current range.

This market will resolve according to the number of Democratic 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.
