Tech billionaire Elon Musk has ignited a firestorm of debate on social media after making a blunt and controversial statement: “No biological man should compete in women’s sports.” The Tesla and SpaceX CEO, known for his unfiltered opinions, shared the comment late Wednesday night on X (formerly Twitter), triggering a wave of both support and backlash across the platform.

Musk, who has increasingly waded into cultural and political issues, was responding to a viral video showing a transgender athlete dominating a women’s competition. “This isn’t fair. It’s a mockery of women’s hard work and biological reality,” Musk wrote. “There must be boundaries rooted in science and fairness. Period.”

The post immediately exploded online, racking up over 50 million views and tens of thousands of replies. Supporters hailed Musk for “saying what everyone is afraid to say,” while critics accused him of promoting transphobia and fueling hate.

LGBTQ+ advocacy groups quickly condemned Musk’s remarks. “This kind of rhetoric endangers transgender people and reinforces harmful stereotypes,” GLAAD said in a statement. “Sports should be inclusive and based on skill, not outdated ideas of biology.”

But conservative commentators and athletes rushed to Musk’s defense. Former NCAA swimmer Riley Gaines, who has become a vocal critic of transgender inclusion in women’s sports, applauded Musk’s stance. “Thank you, Elon, for standing up for fairness and truth,” she posted.

The controversy comes amid growing tensions in the U.S. over policies involving transgender athletes. Several states have passed laws banning transgender women from competing in female sports categories, sparking national legal battles and protests.

Musk’s comment adds yet another layer of intensity to the ongoing cultural war, with many wondering whether his influence as the owner of X and a global tech leader gives his words outsized impact.

As the internet continues to erupt with opinions, one thing is certain: Elon Musk has once again thrown gasoline on one of the most divisive debates of our time — and he’s not backing down.
