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 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 reflects uncertainty in Republican House primaries, with 7-9 losses at 40% slightly edging >15 at 38%, driven by early upsets in Texas' March 4 contests where incumbents Dan Crenshaw (TX-2) and Tony Gonzales (TX-23) failed to advance—Crenshaw losing outright to MAGA-aligned Steve Toth by 18 points and Gonzales withdrawing post-primary. These mark the first two GOP defeats amid factional tensions between establishment and insurgent challengers lacking Trump endorsements, putting others on notice despite historical midterm primary loss averages around 6-7 total incumbents. With only two tallied and key races pending in Pennsylvania (April 22), Wisconsin (April 1 results pending recounts?), Ohio, and late-June states like California and New York, national budget fights or Trump interventions could spark a wave of defeats or solidify incumbents, keeping the contest tight.
