Surprisingly, Meta CEO Mark Zuckerberg has thrown down the gauntlet, expressing his desire for a literal cage match against Tesla CEO Elon Musk.

The saga began on a fateful Tuesday night when Musk responded to a tweet discussing Zuckerberg’s plans to launch Threads, a social media platform positioned as a direct rival to Twitter. It is no secret that Musk and Zuckerberg have clashed before, with Musk taking numerous shots at Facebook‘s founder over their differing approaches to privacy and artificial intelligence. This time was no exception, as Musk delivered yet another subtle jab.

With a hint of sarcasm, Musk tweeted, “I’m sure Earth can’t wait to be exclusively under Zuck’s thumb with no other options,” alluding to Zuckerberg’s already extensive influence over the social media market. However, the situation took an unexpected turn when a Twitter user chimed in, mentioning that they had heard rumors of Zuckerberg’s newfound interest in Brazilian jiu-jitsu.

In response to this remark, Musk playfully wrote, “I’m up for a cage match if he is lol,” insinuating a hypothetical physical confrontation. While Musk’s tweet may have been intended as a joke, Zuckerberg caught wind of it and felt compelled to respond. Taking to his Instagram account, the Facebook founder shared a screenshot of Musk’s tweet, accompanying it with the bold statement, “Send Me Location.”

Zuckerberg’s Instagram feed has recently showcased his dedication to Brazilian jiu-jitsu, featuring photos and videos of him training with professional instructors. Last month, he even boasted about his participation in a jiu-jitsu tournament, where he emerged victorious and claimed a collection of medals. With his training experience, Zuckerberg likely feels confident in his ability to subdue Musk within the confines of a ring.

Adding fuel to the fire, Musk tweeted in response to the news of Zuckerberg accepting the challenge, suggesting the fight take place in the “Vegas Octagon.” While Musk has made subsequent tweets treating the bout as more of a jest, such as his mention of a move called “The Walrus,” where he simply lies atop his opponent, the prospect of an actual showdown remains intriguing.

Undoubtedly, if the match were to materialize, it would capture significant media attention. While it may not reach the iconic stature of the historic 1971 “Fight of The Century” between Muhammad Ali and Joe Frazier, two legendary boxers, a clash between Zuckerberg and Musk, two of America’s most prominent and controversial tech CEOs, would undoubtedly epitomize the peculiarities of our current century and provide ample entertainment.
