Democrats secured five U.S. House seats in Arizona following the November 3, 2026, midterm elections, with all nine districts now called. The delegation split resulted from gains in the open CD1, where Amish Shah defeated Jay Feely, and CD6, where JoAnna Mendoza unseated incumbent Juan Ciscomani, alongside holds in the remaining Democratic strongholds. These outcomes produced a 5-4 majority after Republicans entered with a 6-3 edge. Trader consensus at 100% for five seats tracks the verified tallies and absence of unresolved races or recounts. Shifts could occur only through successful legal challenges or audits in any district, though current margins in Democratic-won seats exceed five points.
