“Zuck v Musk fight will be live-streamed on 𝕏,” he wrote on the social media platform X, formerly known as Twitter. “All proceeds will go to charity for veterans.”

In June, the two billionaires agreed to cage fight after the X owner said that he was ready for it. Zuckerberg replied “send me the location” to Musk’s challenge

The business rivalry between the two has been exacerbated after the Meta owner launched Threads, a challenger to Twitter amid Musk shenanigans. But X has threatened to sue Meta Platforms over its new Threads platform.

This is not the first time, Musk teased Zuckerberg online. Musk has been taunting Zuckerberg on Twitter with zingers like “Zuck my.”

In terms of tech billionaire CEOs literally fighting, Musk versus Zuckerberg would be as good as it gets.

In terms of fighting skill sets, Musk, 51, says he has been in “real hard-core street fights” when he was growing up in South Africa. Meanwhile, Zuckerberg, 39, is an aspirational MMA fighter who is already winning Jiu-Jitsu tournaments.
