Transgender athletes and sports participation
The U.S. Supreme Court is anticipated to issue decisions by June 23, 2026, in two significant cases, *Little v. Hecox* and *West Virginia v. B.P.J.*, that could shape regulations for transgender athlete participation in school sports and state laws, following oral arguments on January 13, 2026, where a majority appeared poised to uphold state bans. As of June 23, 2026, the Trump administration has initiated investigations into Michigan school districts over their transgender-inclusive sports policies, and the U.S. Department of Education announced 18 Title IX investigations on January 14, 2026, targeting schools with policies allowing transgender athletes to compete. The International Olympic Committee (IOC) also announced a new policy in March 2026 banning transgender athletes from competing in women's events at the Olympics, requiring genetic testing. A 2024 IOC-funded study suggested transgender athletes might face physical disadvantages, advocating for sport-specific research before implementing bans. Lindsay Hecox, a key figure in one case, had previously asked for her case to be dismissed as moot.
