Elon Musk says his potential in-person fight with Mark Zuckerberg would be streamed on his social media site X, formerly known as Twitter. The two tech billionaires seemingly agreed to a “cage match” face-off in late June. Zuckerberg is actually trained in mixed martial arts, and the Facebook founder posted about completing his first jiu jitsu tournament earlier this year. “Zuck v Musk fight will be live-streamed on X,” Musk wrote in a post Sunday on the platform. “All proceeds will go to charity for veterans.” Musk said earlier Sunday he was training for the fight by lifting weights. “Don’t have time to work out, so I just bring them to work,” Musk wrote on X.
