Voter sentiment on Washington's Sex Verification Requirements for Female School Sports Initiative remains closely balanced ahead of the November 2026 ballot, with the 52.5% implied probability for passage reflecting divided public opinion on biological eligibility rules for girls' teams. The measure, backed by Let’s Go Washington, would bar biologically male students from female competitions and mandate healthcare documentation of sex for participants, overriding current gender-identity policies. Supporters cite fairness concerns in girls' sports, while opponents highlight potential privacy impacts from verification processes and the state's progressive leanings. Recent qualification of the initiative and internal polling on support levels have kept probabilities near even, with turnout among suburban voters and messaging around implementation details likely to determine the outcome.
