The tweet, which has already racked up more than 100 million views in less than 12 hours, has sparked a digital storm, with supporters hailing Musk as a champion of female athletes, while critics have slammed the movement as transhobic and discriminatory.

Sources close to Musk say he is considering financial lawsuits and lobbying efforts to enforce gender-based policies in biological sporting events, including tennis, golf, MMA and even Olympic qualifier.

The timing of Musk’s statement is no accident. Last week, a women’s golf tournament in California saw a wave of backlash when a transgender woman took home first, sparking heated debates on media platforms.

Athletes and fans are now divided. Tennis star Martina Navratilova has expressed support for Musk’s stance, posting her own tweet with the comment, “Finally, someone with power is speaking out. Justice matters.” Meanwhile, LGBTQ+ advocacy groups have condemned the move, calling it “a direct attack on inclusion and human rights.”

This isn’t the first time Musk has waded into controversial waters. From tough Covid policies to warning about the risks of AI, the SpaceX CEO has never been one to shy away from speaking his mind. But now, critics say he’s straying too far from his lane.

Even so, many are asking: Could Musk’s participation be the tipping point that forces sports federations to reevaluate their policies?

Whether you’re applauding or outraged, one thing is clear: Elon Musk just made sports gender the most popular and most divisive headline of 2025.
