Colorado's eight congressional districts remain under the independent commission map drawn after the 2020 census, with no successful mid-decade redistricting ahead of the November 2026 midterms following the state Supreme Court's June rejection of related ballot measures. Democrats currently hold four seats rated safe or likely (Districts 1, 2, 6, and 7), while Republicans hold the other four, including competitive battlegrounds in District 8 (narrowly Republican-held after 2024 and rated toss-up or tilt Democratic by multiple forecasters) and District 3. Primaries concluded June 30, setting nominees in these races amid a national environment where the out-of-power party typically gains ground. Trader consensus around five or six Democratic seats reflects the balance between locking in the existing four plus one or two targeted flips versus barriers in more Republican-leaning districts, with limited historical precedent for larger swings absent major shifts in turnout or candidate performance.

All Colorado US House of Representatives elections held as part of the 2026 United States midterm election that elect voting members and determine representation in the upcoming 120th congress are included. Special elections to fill a vacancy for the remainder of an unexpired term are not included, whether or not held concurrently with the 2026 United States midterm election. Runoffs for qualifying elections will determine attribution of the relevant seat.
Seats are attributed to the party under which the member was elected. If a member-elect changes party affiliation or vacates their seat after the date of the 2026 United States midterm election, the seat is attributed to the party under which the member was elected.
Members of the House elected as independents who formally caucus, or who announce their intent to caucus, with a party prior to the date of the 2026 United States midterm election are included in that party’s count. If the caucus decisions of relevant members of the US House of Representatives elected as independents cannot be determined as of the date of the 2026 United States midterm 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.
