Myth: Transgender Women Are Dominating Women's Sports
Transgender women athletes represent a vanishingly small fraction of competitors at every level of sport. The political debate treats a hypothetical problem as a widespread crisis — and even the most-cited example, swimmer Lia Thomas, was beaten by four cisgender women in the race used to make the argument.
“"Biological men are identifying as women and dominating female sports, destroying women's athletic opportunities."”
Openly transgender athletes represent approximately 0.01% of NCAA competitors. No professional women's sport has documented a transgender woman achieving sustained dominance. In the most-cited example — swimmer Lia Thomas — Riley Gaines, who became the public face of opposition, tied for 5th place in the 200-yard freestyle, behind four cisgender women.
The political narrative that transgender women are dominating women's sports is not supported by the competitive record. The NCAA estimates that roughly 50 athletes among its approximately 500,000+ competitors are openly transgender — about 0.01% of the total. This small number includes both transgender men and transgender women across all sports and divisions.
The most-cited example is Lia Thomas, a transgender woman who swam at the University of Pennsylvania in the 2021–22 season. Thomas won the NCAA Division I 500-yard freestyle championship in March 2022, a result that generated significant controversy. However, the context matters: in the 200-yard freestyle at the same championship, Riley Gaines — who has since become the most prominent public voice against transgender athlete inclusion — tied for 5th place with Thomas. Four cisgender women placed ahead of both of them. The race is routinely described as one in which Gaines was 'beaten by a biological male' while the four cisgender women who actually outperformed her in the same race are not mentioned.
Thomas's competitive record across the season shows a more complicated picture than the narrative suggests. She placed well in some events and did not in others. Her best times, while competitive at the college level, would not have qualified for Olympic consideration. Claims that she was simply transferring male athletic advantage to dominate women's competition are not reflected in a full accounting of her results.
Governing bodies have responded to the policy question with sport-specific rules. World Aquatics (formerly FINA) adopted rules in 2022 that effectively prevent transgender women from competing in elite international competition if they experienced male puberty. The NCAA subsequently deferred to each sport's governing body. These rules were adopted as a precautionary policy measure — not in response to documented instances of transgender women achieving unfair dominance at the levels they govern.
The policy question of how to handle elite competition is legitimately complex and worth serious discussion. But the rhetoric of widespread domination and destroyed women's sports is not a description of what has actually occurred. Fewer than 50 openly transgender athletes in half a million NCAA competitors have not destroyed women's collegiate athletics. The debate deserves accurate framing.
