Arizona 1st District is the state's headline race: rated Toss-Up by Cook Political Report.

Every seat in the delegation below, in district order. A colored band across the top of a cell means a rater has made a claim about that race. A cell with no band is a settled seat, tinted by its 2024 presidential margin, which is a measured past result and not a 2026 forecast.

No Senate race is in Thin Gold's tracked inventory for Arizona this cycle. This is an assumption, with a reason, not a statutory fact (NBV-394): our inventory not carrying a race may mean no seat is up in Arizona, or it may mean our own coverage has a gap, and we cannot currently tell those two apart.
