Arizona voters will decide Proposition 318 on November 3, 2026, a legislatively referred measure that would require school and athletic association teams to be designated by biological sex recorded at birth, barring males from female teams, while extending similar sex-based rules to restrooms, locker rooms, and showers. Republican lawmakers referred the proposal in June 2026 after the U.S. Supreme Court upheld comparable state laws elsewhere, which also cleared enforcement pathways for Arizona’s existing sports restrictions. Legal challenges alleging single-subject violations were dismissed in July. The measure expands prior statutes to cover private schools and associations and takes effect in 2027 if approved. Trader consensus at 64% for passage reflects Arizona’s partisan legislative alignment, the resolved court path, and the broader national trend of voter-backed sex-based eligibility rules in recent cycles.
