Elon Musk said Sunday that a "cage match" he and Meta CEO Mark Zuckerberg have seemingly agreed to as a fund-raiser will be carried live on X, formerly known as Twitter, which he owns.
"Zuck v Musk fight will be live-streamed on X," Musk posted. "All proceeds will go to charity for veterans."
Zuckerberg soon hit back on Threads, the new app he launched last month in a direct challenge to what was then still called Twitter, saying he was ready.
"Shouldn't we use a more reliable platform that can actually raise money for charity?" he added, in a dig at the wave of problems faced by Musk's platform since he took over last year.
The two billionaire entrepreneurs became direct competitors after Zuckerberg's Meta launched its Twitter-like Threads platform in early July, quickly drawing 120 million users, according to Quiver Quantitative.
Musk then posted on X, "I'm up for a cage match if he is lol," referring to a form of Mixed Martial Arts in which rival fighters employ a variety of techniques -- like wrestling or Brazilian jiu-jitsu -- while limited by few rules.
Zuckerberg, a martial arts enthusiast who has taken part in jiu-jitsu competitions, responded to Musk's initial, seemingly humorous, challenge by replying on Instagram "Send me location."
The 39-year-old Zuckerberg, with his fighting experience, emerged as the clear favorite despite the decided size advantage of Musk, who is 52.
No date has been set for the fight, which -- if it does happen -- is expected to take place in Las Vegas.
