Colorado's eight congressional districts enter the 2026 cycle evenly divided at four seats each following the 2024 results, with District 8 remaining the clearest swing seat after Republicans captured it by a narrow margin. Safe Democratic holds in Districts 1, 2, 6, and 7 anchor the floor near four or five seats, while competitive dynamics in District 8 and potential pressure on Republican-leaning seats in the 3rd and elsewhere keep five- and six-seat outcomes closely matched in trader pricing. Midterm national conditions, candidate recruitment after June primaries, and any shifts in generic ballot trends or district-specific polling will determine whether Democrats expand beyond their current map or remain near parity. Late-cycle developments such as turnout patterns or economic signals could widen separation between the leading outcomes.

This market will resolve according to the number of seats in the US House of Representatives won by the Democratic Party in Colorado in the 2026 United States midterm election.
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.
