It’s not uncommon to see two high-profile people square off for an MMA fight these days. It’s become common for YouTubers and podcasters to step into the ring — especially if there’s some sort of ongoing rivalry.

Now it seems like the growing list of amateur fighters may soon include two of tech’s biggest players.

On June 20, Musk tweeted that he’d be “up for a cage match” with Zuckerberg after learning that Meta plans to release a Twitter alternative named “Threads.”

In response, Zuckerberg screen capped Musks’s tweet, added “send me location,” and posted it to his Instagram story.

While it’d be easy to assume this was a joke, a Meta spokesperson told The Verge that it wasn’t.

Musk suggested the Vegas Octagon, and then playfully responded by saying, “I have this great move that I call “The Walrus”, where I just lie on top of my opponent & do nothing.”

The Verge points out that while Musk dwarfs Zuckerberg in terms of sheer physical size, Zuckerberg has already begun winning Jiu-Jitsu tournaments.

Wheher or not the fight will happen remains to be seen. Musk has a habit of routinely making claims that he later attempts to back out of.
