In 2026, voters will decide at least five ballot measures concerning sex-based requirements for school athletics and bans on certain medical procedures for transgender minors, including:
- three ballot measures in Arizona , Colorado , and Washington to establish sex-based requirements for participation on school athletic teams, with the specific regulations and methods for determining sex varying, and
- two ballot measures in Colorado and Missouri to prohibit certain medical and surgical procedures for transgender minors when provided to alter sex characteristics.
Voters in Nebraska could see a citizen-initiated constitutional amendment to prohibit "athletic teams or sports designated for females, women, or girls" from being "open to students of the male sex." On June 30, 2026, the campaign behind the initiative filed signatures, which local officials must review within 40 days of receiving them.
