Elon Musk and Mark Zuckerberg, two of the world's leading tech billionaires, have agreed to face off in a cage match.

Musk said on his Twitter account that he was "up for a cage fight" with Zuckerberg, reports BBC.

Zuckerberg, CEO of Facebook and Instagram parent company Meta, subsequently tweeted a copy of Musk's message with the comment "send me location."

"The story speaks for itself," a Meta spokesperson told the BBC.

Musk responded to Zuckerberg's remark with the words "Vegas Octagon."

The Octagon is the fenced-in enclosure and competition mat used for Ultimate Fighting Championship (UFC) fights. The UFC is headquartered in Las Vegas, Nevada, said the report.

Musk, who turns 52 later this month, also tweeted: "I have this great move called 'The Walrus,' where I just lie on top of my opponent and do nothing."

"I almost never work out, except for picking up my kids & throwing them in the air," he tweeted.

Meanwhile, Zuckerberg, 39, has begun practicing mixed martial arts (MMA) and has lately won jiu-jitsu contests, added the report.

The back-and-forth has gone viral, with social media users arguing who would win the battle and others posting parodies such as made up ads advertising the fight.

Meta presented coworkers layouts for a text-based social network aimed to compete with Twitter earlier this month, sources told the BBC.

It may allow users to follow profiles they currently follow on Meta's image-sharing app Instagram.

It may help the firm to gain followers via decentralized networks such as Mastodon, the report also said.

A Meta representative acknowledged to the BBC that the platform was in the works.

The text-based network, called P92, may prove to be a more formidable competitor to Elon Musk's Twitter than BlueSky or Mastodon.
