In a blunt statement posted on X (formerly Twitter), Musk called for an immediate proposal to ban all tournaments that allow biological men to compete in women’s categories, saying it’s “unfair, unsafe, and blatantly anti-science.”

“This is not about hate. It’s about preserving fairness in women’s sports,” Musk wrote. “Let women compete against women. Period.”

The tweet, which has already racked up over 100 million views in under 12 hours, triggered a digital earthquake, with supporters hailing Musk as a defender of female athletes, while critics slammed the move as transphobic and discriminatory.


Sources close to Musk say he’s considering funding legal action and lobbying efforts to enforce biological-based gender policies in global sporting events—including tennis, golf, MMA, and even Olympic qualifiers.


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

Athletes and fans alike are now divided. Tennis star Martina Navratilova expressed support for Musk’s stance, reposting his tweet with the comment, “Finally, someone with power speaks up. Fairness matters.” Meanwhile, LGBTQ+ advocacy groups condemned the move, calling it “a direct attack on inclusivity and human rights.”

This isn’t the first time Musk has dived into controversial waters. From challenging COVID policies to warning against AI risks, the SpaceX CEO has never been one to shy away from speaking his mind. But now, critics argue he’s venturing too far outside his lane.

Still, many are asking: could Musk’s involvement 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 gender in sports the hottest—and most divisive—topic of 2025.
