Katie Hobbs holds an 89.5% implied probability as Maricopa County winner in the 2026 Arizona gubernatorial race, reflecting trader consensus on her incumbency advantages in the state's most populous county. Andy Biggs trails at 7%, with other named candidates and "Other" options priced at 50%. Key drivers include Hobbs' established support among urban and suburban voters in Maricopa, historical Democratic performance in Phoenix-area precincts, and the early stage of Republican primary dynamics ahead of the November election. Recent polling trends and candidate positioning in the battleground state have reinforced this positioning without major shifts in the past 30 days. Resolution depends on certified county results following the general election.
