Elon Musk, Mark Zuckerberg agree to cage match – but why?

It may not be a fight to the death for two of the universe’s most high-profile tech billionaires, but Elon Musk and Mark Zuckerberg have agreed to a cage match.

“I’m up for a cage match if he is,” the 51-year-old Twitter CEO posted in a Twitter thread Tuesday after striking back at a user’s post referencing Zuckerberg’s jiu-jitsu experience.

“Send me location,” Zuckerberg, the founder and CEO of Facebook and Instagram parent company Meta, responded in an Instagram story Wednesday, which included a screenshot of Musk challenging him.

“Vegas Octagon” Musk responded, adding: “I have this great move that I call ‘The Walrus’ where I just lie on top of my opponent & do nothing.”

‘Be careful’

The exchange between the famous techies came on the heels of Musk tweeting, “I’m sure Earth can’t wait to be exclusively under Zuck’s thumb with no other options.”

Zuckerberg, 38, recently competed in his first jiu-jitsu tournament and won gold and silver medals, he announced last month on Instagram.

Another Twitter user then cautioned Musk to “Be careful… I heard Zuckerberg does jiu jitsu now,” spurring the Twitter CEO’s cagematch remark.

Another new Twitter competitor?

Earlier this month, the Verge reported Meta is working on a Twitter competitor potentially called Threads, and talking to celebrities including Oprah about being early users.

Chris Cox, Meta’s chief product officer, said it is the company’s “response to Twitter,” the outlet reported.

“We’ve been hearing from creators and public figures who are interested in having a platform that is sanely run, that they believe that they can trust and rely upon for distribution,” Cox said, according to The Verge.
