UPDATE: Elon Musk and Mark Zuckerberg appear to agree to fight in cage match, Meta says Zuck is serious

Zuckerberg's response on Instagram simply said "Send Me Location."

Zuckerberg has been practicing jiu-jitsu and just posted a picture of himself doing a Murph challenge for Memorial day. A Murph consists of running a mile, doing 100 pull-ups, 200 push-ups, and 300 squats, then running a mile at the end in under an hour. Zuckerberg did it in 39 minutes.

After seeing that, Zuckerberg had treated the offer seriously, Elon responded saying, "If this is for real, I will do it."

The Verge reported that "I’ve confirmed that Zuckerberg’s post on his Instagram account is, in fact, not a joke, which means the ball is now in Musk’s court."

"The story speaks for itself," Meta spokesperson Iska Saric told the outlet.

Musk responded to the story on Twitter, writing, "Vegas Octagon." Musk wrote in a separate comment, "I have this great move that I call 'The Walrus', where I just lie on top of my opponent & do nothing"

The two tech founders, aside from fighting in anything resembling a boxing ring, have been in the fight for a time in market share. While Facebook has had a large market share for a while, it has been declining in recent years while Twitter has been rising.

According to rumors, many creators and public figures have gotten fed up with Twitter and the way it has been run by Musk as he has freed up the platform for free speech.

According to a report, the app has been codenamed 'Project 92' internally at Meta and will be called 'Threads' upon being released.

A Meta spokesman told the BBC, "We believe there's an opportunity for a separate space where creators and public figures can share timely updates about their interests."

This is a breaking story and will be updated.
