Four states vote Tuesday on ballot measures that could reshape girls' and women's sports nationwide

Four states—Arizona, Nebraska, Washington, and Colorado—are voting on ballot measures that could significantly alter participation rules for transgender athletes in girls’ and women’s sports, including locker room access. Existing laws in Arizona and Nebraska restrict biological males, while Washington and Colorado are considering new statewide restrictions. The measures propose varying levels of verification for biological sex, with opponents raising concerns about discrimination and invasive examinations, while supporters emphasize fairness, privacy, and safety.

• Arizona and Nebraska currently have laws restricting biological males from competing in female sports, with ballot measures potentially expanding or strengthening these.
• Washington and Colorado are voting on measures that would establish statewide sex-based restrictions for school sports, changing their current gender identity-based eligibility rules.
• Proponents argue these measures ensure fair competition and protect female athletes, while opponents cite concerns of discrimination against transgender students and potential for invasive medical checks.
• Arizona’s measure would also extend restrictions to private schools and athletic associations and address restroom and locker room access based on biological sex.
• Nebraska’s measure aims to enshrine existing restrictions into the state constitution, making them harder to overturn.
• Predictions from Polymarket show varying probabilities of success for each measure, with Arizona’s measure having the highest likelihood of passing.
