Republicans currently hold a narrow House majority of roughly 218 seats entering the 2026 midterms. Trader pricing on exact seat ranges centers on substantial losses, with the leading outcome below 190 seats reflecting the historical pattern of the president's party losing ground in midterm cycles combined with generic ballot polls showing Democrats ahead by 4–7 points. Mid-decade redistricting in states including Texas, North Carolina, and California has altered the map, while race ratings from Cook Political Report and similar analysts identify dozens of competitive districts, many held by Republicans. Key differentiators among ranges include the scale of Democratic gains in battleground seats, turnout among key voting blocs, and any late-cycle shifts in national conditions. Factors that could consolidate support around one band include further polling consolidation, primary outcomes, or resolution of open-seat dynamics.

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.
