The even 4-4 split in Colorado’s eight congressional districts after 2024, combined with the single true toss-up in the 8th District, anchors trader expectations near five or six Democratic seats. Post-June primaries, Republican Gabe Evans faces Democrat Manny Rutinel in that northern suburban and Weld County battleground, while Republican-held districts 3 and 5 show limited openings amid a national environment favoring modest Democratic gains. Court rejection of mid-decade redistricting proposals locked in the current map, removing any structural shift before November. With five districts rated safe or likely for one party, the narrow range between five and six seats reflects uncertainty over whether Democrats flip the 8th and possibly one additional seat, or hold steady at four plus one pickup.

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.
