Two of the world's most high-profile technology billionaires - Elon Musk and Mark Zuckerberg - have agreed to fight each other in a cage match, BBC News reports.

Mr Musk posted a message on his social media platform Twitter that he was "up for a cage fight" with Mr Zuckerberg.

Mr Zuckerberg, the boss of Facebook and Instagram parent company Meta, then posted a screenshot of Mr Musk's tweet with the caption "send me location".

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

Mr Musk then replied to Mr Zuckerberg's response with: "Vegas Octagon."

The Octagon is the competition mat and fenced-in area used for Ultimate Fighting Championship (UFC) bouts. The UFC is based in Las Vegas, Nevada.

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

He later tweeted short videos of walruses, perhaps suggesting his challenge to Mr Zuckerberg may not entirely be serious.

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

Meanwhile, 39-year-old Mr Zuckerberg has already been training in mixed martial arts (MMA) and has recently won jiu-jitsu tournaments.
