A proposed MMA cage match between Elon Musk and Mark Zuckerberg has been described as “the biggest fight in the history of the world” by UFC boss Dana White, even if it consists of two of the most unlikely competitors ever to step inside the octogan. The tech billionaires have put the combat world’s promoters on red alert after 52-year-old Musk appeared to accept an invitation to square up with Facebook co-founder Mark Zuckerberg in a charity cage match.

The Meta CEO is 13 years younger than Musk and has recently taken up Brazilian jiujitsu as a means of focusing his mind on something fully. However, pictures have already emerged online of Musk appearing to be in training for the yet-to-be-confirmed super-fight.

Lex Fridman, a scientist at the Massachusetts Institute of Technology, tweeted: “I did an impromptu training session with Elon Musk for a few hours yesterday,” alongside two photos from the session.

“I’m extremely impressed with his strength, power, and skill, on the feet and on the ground. It’s really inspiring to see Elon and Mark doing martial arts, but I think the world is served far better if they train martial arts but not fight in the cage.”

Fridman’s view is not shared by everyone, however, with UFC boss White convinced that a cage match between the two billionaires would attract more than 25 million per-per-view sales at £78.50 each, making it the highest-grossing fight of all time.

White told TMZ Sports: “I probably spent an hour and a half with them on the phone, both guys are absolutely dead serious about this. This would be the biggest fight ever in the history of the world. Bigger than anything that’s ever been done, it would break all pay-per-view records, these guys would raise hundreds of millions of dollars for charity.”

But while the two tech fighters size each other up and try and get into the best physical shape for the proposed showdown, a look at their key financial statistics show who is winning in the battle of the boardroom.

Twitter Chairman Musk is the world’s richest man with a staggering net worth of £185bn. The South African-born investor co-founded spacecraft manufacturer SpaceX, electric car company Tesla and tunnel-making firm The Boring Company.

He bought the social media platform in 2022 for £34.8m but now owns a 74% stake in the company.

Zuckerberg currently has a net worth of 99.9bn and made his fortune by co-founding the social media platform Facebook at Harvard University. After taking the world by storm with his networking system, Facebook later acquired Instagram and the world’s most widely-used mobile chat app WhatsApp.

Although both men are wealthy beyond the wildest dreams of almost everyone else, the lives they lead could not be more different.

Zuckerberg owns a £253m real estate portfolio, primarily based in California. But last year, Musk sold all seven of his properties, some of which were also in the sunshine state, before moving into a modest rented home in Boca Chica, Texas that is believed to be only worth £39,600.

Musk is currently single but is the father of 10 children to three different women including triplets and two sets of twins. That is very different to Zuckerberg, who has three children with wife Priscilla Chan.

Despite his gigantic fortune, Tesla chief Musk is said to now live a minimalist life. Will that give him the edge when it comes to taking on the complex mind of Zuckerberg in the cage? The winner will need more than an endless supply of cash to get their arm raised at the end.
