Arizona voters will decide Proposition 318 on November 3, 2026, a legislatively referred measure that would require schools and athletic associations to designate teams by biological sex as listed on original birth certificates, bar males from female teams, and restrict restroom, locker room, and shower access based on that definition. Republican legislative majorities referred the proposal in June 2026 after earlier court blocks on a 2022 law. A June 30, 2026, U.S. Supreme Court ruling upholding similar state restrictions in Idaho and West Virginia removed key legal obstacles and clarified enforcement paths. Legal challenges alleging single-subject violations reached Maricopa County Superior Court but did not prevent ballot placement. These factors, combined with the measure’s expansion of existing statutes and the November timeline, underpin traders’ 64.5% implied probability for passage.
