Facebook co-founder Mark Zuckerberg and Twitter CEO Elon Musk have agreed to a cage match. Musk initially proposed the match on Twitter, and Zuckerberg responded on Instagram stating, "Send Me Location." This is not the first time Musk has challenged notable figures via Twitter, as he previously attempted to engage in "single combat" with Russian President Vladimir Putin. In response to an elaborate training regimen suggestion from Chechen leader Ramzan Kadyrov, Elon even offered to fight with his non-dominant hand. In contrast, Zuckerberg has been training in jiu-jitsu for over a year and has expressed his enthusiasm for the sport on The Joe Rogen Experience podcast.
