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.
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 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.
Twitter did not provide a statement when contacted by the BBC for comment.
Earlier this month, Meta showed staff plans for a text-based social network designed to compete with Twitter, sources have told the BBC.
It could allow users to follow accounts they already follow on Instagram, Meta’s image-sharing app.
It could potentially allow the company to bring over followers from decentralised platforms such as Mastodon.
A Meta spokesperson confirmed to the BBC that the platform was in development.
The text-based network – which has a working title of P92 – could turn out to be a greater rival to Elon Musk’s Twitter than either BlueSky or Mastodon.
