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.Arizona’s nine House districts feature three safe Democratic seats and two highly competitive Republican-held battlegrounds in AZ-1 and AZ-6 that nonpartisan ratings classify as toss-ups. Post-July primaries, Democrats nominated Amish Shah in the open AZ-1 while Republicans chose Jay Feely; in AZ-6, Juan Ciscomani faces JoAnna Mendoza in a rematch. Recent polling averages in both districts show narrow margins, with some surveys giving Democrats small leads amid broader statewide trends favoring Gov. Katie Hobbs. Traders price five Democratic seats highest because one net gain appears the most probable outcome given current candidate matchups, fundraising, and district leans, while four or six seats remain plausible if either or both toss-ups break the same way. The low odds on three or seven-plus seats reflect limited structural openings beyond these two races.
