The rules clearly specify what constitutes control of the House, defining it primarily by a majority of voting seats and providing an explicit tiebreaker based on the affiliation of the first elected Speaker of the 120th Congress. Edge cases are directly addressed: seats decided by runoffs count toward the final total, post-election party switches or vacancies do not alter initial election attribution, and independent caucus affiliations have a defined January 4 cutoff date. Resolution relies on official election authorities, congressional records, and credible reporting consensus. Resolution timing may extend into January if margins are narrow, runoffs occur, or independent caucus decisions remain pending.

Market explained before close
This market measures whether the Republican Party wins control of the U.S. House of Representatives in the 2026 midterm elections for the 120th Congress.
How it resolves
The market resolves Yes if the Republican Party wins a majority of voting seats in the House in the 2026 midterms, or if no party wins a majority and the first elected Speaker of the House is affiliated with the Republican Party. The market resolves No if another party wins control under these rules. Seats are attributed to the party under which members were elected, even if they later change affiliation or vacate the seat. Runoff results determine seats decided by runoffs. Independents count toward a party if they formally caucus with it or announce their intent to caucus by January 4th at 11:59 PM ET of the following year. Official state electoral authorities, the U.S. Congress, and a consensus of credible reporting decide the outcome.

Resolution rules at close
This market will resolve according to the party that wins control of the United States House of Representatives in the 2026 United States midterm election. A party wins control of the United States House of Representatives if it wins a majority of the chamber’s voting seats. If no party wins a majority of voting seats, the chamber will be deemed controlled by the party with which the first elected Speaker of the House of the Congress that convenes after the 2026 midterm election is affiliated. The following rules govern the counting of seats for determining which party wins control of the chamber. All House elections in the 2026 United States midterm election that elect voting members and determine representation in the upcoming 120th Congress are included. 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, a party are included in that party’s 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.
