Billionaire Showdown: Mark Zuckerberg Offers to Fight Elon Musk in a ‘Cage Match’

The kings of social media suddenly sound like feuding fighters. But are they really serious?

“Vegas Octagon,” Elon Musk tweeted to Mark Zuckerberg Wednesday night.

That followed Zuckerberg posting an Instagram story in which he said, “Send me location” for a “cage match.”

According to Variety, this all started in early May when the founder of Facebook entered a jiu jitsu tournament for the first time. He posted six photos on Instagram, as he won a gold and a silver medal.

“Won some medals for the Guerrilla Jiu Jitsu team,” Zuckerberg wrote.

 A follow-up video last weekend showed Zuckerberg, 38, wrestling a teammate.

“Starting to prepare for our MMA debuts,” he wrote with a winking emoji.

Musk, who turns 52 next week, responded Tuesday in a Twitter thread. He replied to a report that Zuckerberg’s parent company Meta is releasing a “Twitter rival called Threads.”

“I’m up for a cage match if he is,” Musk wrote. He later added, “Zuck my (tongue emoji).”

That led to Zuckerberg’s call for a locale Wednesday, which Musk quickly provided.

“If this is for real, I will do it,” Musk added when a follower offered to be his training partner.

But Musk later indicated his Twitter trash talk was tongue-in-cheek. For one thing, he called the idea of a cage match “hilarious.

“I have this great move that I call ‘The Walrus,’ Musk tweeted. “I just lie on top of my opponent and do nothing.”

Musk admitted he hardly ever exercises, “except for picking up my kids and throwing them in the air.”

One tweet suggested Musk would have a height advantage in the ring. He reportedly stands six-foot-two, while Zuckerberg is five-foot-eight.

However, Zuckerberg could have the advantage in endurance. At least verbally. Facebook posts have no space limit, while Twitter posts are limited to 280 words.
