Lia Thomas Banned From Competing in 2025 Olympics, Officials Say She Should “Swim With Men”

The swimming world is in turmoil following the shock announcement that Lia Thomas, the first transgender woman to win a national swimming title in the United States, has been banned from competing in the 2025 Olympic Games in Paris. The International Olympic Committee (IOC) and the International Swimming Federation (FINA) confirmed the decision on Thursday, saying that Thomas, 25, no longer meets the eligibility criteria for women’s competition and must “swim with men” if she wants to continue competing at the international level. The announcement has sparked a wave of controversy, dividing opinion among athletes, fans and transgender rights advocates.

Lia Thomas gained notoriety in 2022 when she became the first openly transgender woman to win the NCAA national title in the 500-yard freestyle, marking a historic milestone for inclusion in the sport. However, she has since faced intense scrutiny over her participation in women’s competitions, with critics arguing that her late transition (Thomas competed as a man in college swimming before identifying as a woman in 2019) gives her an unfair physical advantage. The IOC, revising its 2021 guidelines on transgender athletes, implemented new rules in 2024 that require transgender female athletes to demonstrate testosterone levels below a certain threshold for a period of two years before competing, in addition to undergoing additional “competitive advantage” assessments.

In an official statement, FINA said: “After a detailed review of Lia Thomas’ medical data, competition history and physiological assessments, we have determined that she does not meet the current criteria to compete in women’s events. Based on our equity and inclusion policy, we recommend that she compete in men’s categories or in open categories, if available, to ensure fair competition for all athletes.” The IOC endorsed the decision, saying the new guidelines aim to “protect the integrity of sport” while striking a balance between inclusion and competitive fairness.

Thomas, who had qualified for the 2024 U.S. Olympic Trials, expressed her disappointment in an emotional Instagram post. “I have dedicated my life to swimming and have dreamed of the Olympic Games since I was a child. To be banned in this way is devastating, not only for me, but for all transgender athletes who want to compete with dignity. I will fight this decision and seek justice,” she wrote, drawing immediate support from activists and athletes like Megan Rapinoe, who tweeted at X: “This is a step backwards for inclusion in sports. Lia deserves to compete just like any other woman.”

However, the decision was also applauded by some athletes and sports experts. Riley Gaines, a former NCAA swimmer and vocal critic of transgender inclusion policies, posted on X: “Finally, a decision based on biology and fairness. Lia Thomas has an undeniable physical advantage, and this is not fair to cisgender women who have been training their entire lives.” The comment garnered more than 1 million likes, reflecting the polarized debate surrounding the participation of transgender athletes.

In recent years, Thomas’s participation in women’s competitions has sparked heated debate, with online petitions collecting millions of signatures both in favor and against her eligibility. In 2023, FINA introduced an “open” category for transgender athletes, but few national federations have adopted it, leaving Thomas and other transgender athletes in competitive limbo. The IOC, under pressure from national committees like USA Swimming, revised its guidelines in response to complaints of “unfair advantages” based on biological differences such as height, wingspan and muscle density.

The IOC and FINA’s decision was met with protests in Paris, where transgender rights activists gathered outside the committee’s headquarters, holding signs with slogans such as “Sport is for everyone” and “Let Lia swim.” At the same time, traditional swimming fans in the X used the hashtag #FairPlayInSports, with messages such as “Cisgender women deserve a level playing field. This decision is necessary.”

Thomas’ future in the sport remains uncertain. While she has indicated she will appeal the decision, the ban could end her Olympic dreams and limit her competitive opportunities. USA Swimming, which has previously supported her, issued a cautious statement: “We respect the IOC and FINA guidelines but remain committed to supporting all of our athletes, including Lia, as we navigate these complex issues of inclusion.”

As the world awaits the outcome of any appeals, Lia Thomas’s case continues to shape the global conversation about gender in sport. Already facing logistical and political challenges, the 2025 Olympic Games now face a controversy that could redefine the rules for transgender athletes forever.
