Arizona’s nine House districts feature two battlegrounds that shape trader expectations for Democratic seat totals ahead of the November 3 election. AZ-1, an open seat after the Republican incumbent’s retirement, and AZ-6, held by a Republican, show Democratic advantages in recent polling averages and forecasts, consistent with a broader national environment favoring the party in swing districts. Safe Democratic seats in AZ-3, AZ-4, and AZ-7 anchor a floor near five wins, while the competitive pair drives the market’s leading 5-seat outcome. Shifts in turnout among suburban and independent voters or late campaign spending could still alter the final count in these marginal races.
