This market will resolve according to the number of seats in the US House of Representatives won by the Democratic Party in Arizona in the 2026 United States midterm election. All Arizona 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.Democrats currently hold three Arizona House seats rated safe or likely Democratic, while two Republican-held districts stand out as toss-ups that could determine the final tally. District 1, an open seat after incumbent David Schweikert retired to run for governor, features a competitive matchup with Democratic nominee Amish Shah facing Republican Jay Feely in a closely divided Phoenix-area district. District 6 pits Republican Juan Ciscomani against Democrat JoAnna Mendoza in another tight contest. Post-July 2026 primaries, these races plus the broader national environment—with Democrats holding a generic ballot edge—drive trader consensus around five total Democratic seats as the most probable outcome, though shifts in turnout or late developments could alter results in the toss-ups.
