**Arizona's 2026 gubernatorial race between incumbent Democrat Katie Hobbs and Republican challenger Andy Biggs features a competitive contest that has tightened in recent weeks, with polls showing Hobbs ahead by margins ranging from double digits to within the margin of error.** Early voting began October 7 after the October 5 registration deadline, and the race's visibility—coupled with substantial outside spending, including Turning Point USA ads targeting Hobbs—supports expectations of turnout modestly above the roughly 2.29 million ballots cast in the 2022 governor's race. Trader consensus centers on the 2.45M–2.9M range because the contest remains sufficiently close to mobilize core supporters and independents without the surge seen in presidential years, while third-party candidates on the ballot add minor cross-pressure. Recent polling averages (Hobbs roughly 46–49% to Biggs 38–44%) and the state's accessible mail and early-voting options reinforce a baseline of solid participation consistent with the leading outcome bands. No late-breaking events have altered this trajectory in the immediate term.
