The U.S. Supreme Court’s recent ruling affirming states’ authority to ban transgender girls and women from female sports teams has intensified efforts by conservative groups to extend such restrictions nationwide, particularly targeting Democratic-led states that currently allow transgender athletes to compete according to their gender identity.

On Tuesday, the Court upheld policies in 27 states that prohibit transgender female athletes from participating in girls’ and women’s teams, ruling that discrimination on the basis of “sex” under Title IX refers to biological sex rather than gender identity. However, the decision did not mandate bans in states that permit transgender participation, leaving the issue to be decided by individual states.

Following the ruling, conservative organizations, including the Alliance Defending Freedom (ADF), which successfully argued the case, announced plans to pursue additional litigation. ADF currently supports three cases challenging policies in blue states, while the U.S. Department of Justice (DOJ), under the Trump administration’s directive, has filed lawsuits against Maine, California, and Minnesota for allowing transgender students to compete. In addition, several investigations into state athletic associations and school districts remain ongoing.

Kristen Waggoner, president of ADF, signaled an aggressive legal strategy moving forward, stating via social media that “blue states with boys on girls’ podiums … you’re next.” The Education Department also pledged to maintain its enforcement efforts, with Secretary Linda McMahon calling the court’s decision “a tremendous victory” and affirming the administration’s commitment to ensuring compliance nationwide.

Democratic leaders and transgender rights advocates expressed cautious optimism despite the ruling. They emphasized that the Court’s opinion left room for states to maintain inclusive policies. Minnesota Governor Tim Walz stated that the decision enables states to choose their approach, asserting that his state will continue to support transgender athletes. Legal advocates noted that the Court deferred to state legislatures and schools on competing medical and scientific assessments related to transgender participation in sports.

The controversy largely centers on K-12 athletics, where cases are concentrated following policy shifts by collegiate organizations such as the NCAA. Litigation includes longstanding cases in Connecticut and Minnesota, as well as a recent suit in Washington state involving allegations of sexual assault during a wrestling tournament.

Data suggest that the number of transgender student-athletes affected is very small. For example, fewer than 10 of approximately 250,000 student-athletes in Washington state identify as transgender, and only two transgender girls have competed in Florida public school girls’ sports over the past decade.

Despite the limited direct impact, public debate remains highly politicized. A 2025 survey indicated that two-thirds of Americans support requiring transgender athletes to compete on teams matching their sex assigned at birth, reflecting a recent uptick in support for such measures. The Trump administration has leveraged this sentiment by signing an executive order denying federal funding to schools that permit transgender participation on girls’ teams, further heightening tensions.

Looking ahead, the legal battles are expected to focus on Democratic states’ policies, some of which allow transgender athletes to compete without restrictions, while others impose criteria such as hormone therapy. Experts suggest that states with eligibility rules addressing concerns over fairness and safety might have stronger legal standing in forthcoming court challenges.

The issue will also be contested at the ballot box in several states this year, including Colorado, Washington, and Arizona. Colorado voters will decide on Initiative 109, which seeks to restrict students to sports teams aligned with their sex assigned at birth.

Amid the ongoing litigation, some LGBTQ+ advocates stress the importance of seeking solutions beyond the courts. Shawn Thomass Merkermaper, managing attorney at the Transgender Law Center, urged communities to focus on rights promotion, safety, and solidarity outside the judicial system, noting skepticism about the Supreme Court’s approach to transgender litigants.
