It looks like Meta CEO Mark Zuckerberg has channeled his inner ‘Khabib Nurmagomedov’ and accepted Elon Musk’s cage match challenge as he asked the Space X owner to send him the location.

The development was also confirmed by Meta spokesperson Iska Saric.

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, she said.

Musk has responded, with two words: Vegas Octagon.

Musk recently tweeted that he would be up for a cage fight with Zuckerberg.

This is not the first time, Musk teased Zuckerberg online. Musk has been taunting Zuckerberg on Twitter with zingers like “Zuck my.”

In terms of tech billionaire CEOs literally fighting, Musk versus Zuckerberg would be as good as it gets.

In terms of fighting skill sets, Musk, 51, says he has been in “real hard-core street fights” when he was growing up in South Africa. Meanwhile, Zuckerberg, 39, is an aspirational MMA fighter who is already winning Jiu-Jitsu tournaments.
