evidence: Elon Musk and Mark Zuckerberg are going to have a cage match, or at least that’s what they’ve been telling the world. The whole thing started in June because of an internal Meta meeting recording The Verge heard, in which Meta chief product officer Chris Cox said Meta’s Twitter competitor Threads would be "sanely run" in a clear jab at Musk’s Twitter reign. When a Twitter user warned Musk about Zuckerberg’s jiu-jitsu training, Musk responded that he was "up for a cage match if he is lol." Zuckerberg seemingly accepted in an Instagram post the same day. [...] Elon Musk says he’ll fight Mark Zuckerberg "any place, any time, any rules."Musk famously challenged the Meta CEO to a cage match last year that Zuckerberg agreed to but never happened. [...] Elon Musk and Meta CEO Mark Zuckerberg’s cage match will be livestreamed on Musk’s Twitter, which is currently rebranding to X, according to a post from Musk early this morning. Musk says the proceeds will go to charity for veterans.
