This market will resolve according to the Republican Party’s seat count in the U.S. House of Representatives as a result of the 2026 United States midterm election scheduled for November 3, 2026. The seat count includes all House elections in the 2026 United States midterm election that elect voting members and determine representation in the upcoming 120th Congress. Where a seat is decided by a runoff, the runoff result will determine attribution of that seat. Seats are attributed to the party under which the member was elected. If a member-elect changes party affiliation, or vacates their seat, between election day and the formal organization of Congress, the seat is attributed to the party under which the member was elected. House members elected as independents who formally caucus with, or, for newly elected members, who announce their intent to caucus with, the Republican party are included in the count. If the caucus decisions of members of the House elected as independents cannot be determined on the date of the election, this market may remain open until the earlier of (i) an announcement from the relevant members of their intents to caucus, or (ii) January 4th, 11:59 PM ET of the following calendar year. If no such announcement is made by January 4th, 11:59 PM ET of the following calendar year, the member will not count towards the seat count of any party. The resolution sources for this market will be official information from relevant state electoral authorities, the United States Congress, and a consensus of credible reporting.Republicans currently hold a narrow House majority of roughly 218 seats heading into the November 2026 midterms, but trader consensus on the Polymarket heavily favors outcomes below 210 seats. Recent polling shows Democrats leading the generic ballot by about four points amid President Trump’s approval ratings in the mid-30s to mid-40s. Historical midterm patterns for the president’s party, combined with Democratic advantages in special elections and competitive districts, underpin expectations of net Republican losses despite mid-cycle redistricting gains in states such as Texas. Upcoming primaries, candidate recruitment, and any shifts in the national environment over the next three months remain the main variables that could consolidate support around a narrower or wider loss range.
