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 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.Trader consensus on Polymarket heavily favors 4-6 Democratic House incumbents losing their 2026 primaries at 70.6%, reflecting a surge in intra-party challenges from progressives and younger candidates targeting moderates amid post-2024 election frustrations over leadership, Israel policy stances, and generational divides. Early March primaries in Texas and North Carolina produced no confirmed House incumbent defeats—figures like Reps. Lizzie Pannill Fletcher and Veronica Escobar advanced, though some Texas races headed to runoffs—yet close fundraising gaps and voter turnout signals in state races underscore upset potential. With 15+ competitive primaries pending, including California's June top-two contests featuring challengers to Reps. like Zoe Lofgren and Jimmy Panetta, historical base rates of rare incumbent losses (under 5%) are offset by this cycle's crowded fields and base anger, positioning 4-6 as the skin-in-the-game expectation while <3 remains viable if incumbency holds.
