Elon Musk is still insisting he's down to fight Mark Zuckerberg: 'Any place, any time, any rules'

Musk had challenged Zuckerberg to a cage match last year after Meta decided build its own X competitor.

• Elon Musk says his offer to fight Mark Zuckerberg still stands.
• "I'll fight Zuckerberg any place, any time, any rules," he said on Wednesday.
• Musk challenged Zuckerberg to a cage match last year after Meta decided to build their own X rival.

Elon Musk is impressed with Meta's latest AI model, but he's still raring for a bout in the ring with Mark Zuckerberg.

"I'll fight Zuckerberg any place, any time, any rules," Musk told reporters in Washington on Wednesday.

The mercurial billionaire traveled to Capitol Hill to attend Israeli Prime Minister Benjamin Netanyahu's address to Congress.

A Meta representative pointed Business Insider to a Threads post that Zuckerberg made on Wednesday in response to Musk's remark.

"Are we really doing this again?" Zuckerberg wrote.

Talk of a Musk-Zuckerberg fight started in June 2023, when Musk issued the challenge amid speculation that Meta was building their own X competitor. Zuckerberg would go on to launch his text-based social media platform, Threads in July.

But the fight failed to materialize despite much back and forth between the two billionaires.

"I've been ready to fight since the day Elon challenged me. If he ever agrees on an actual date, you'll hear it from me," Zuckerberg wrote in a Threads post on August 11. "Until then, please assume anything he says has not been agreed on."

That, however, hasn't stopped Musk from bringing up the idea of a cage match every now and then.

When Mark Zuckerberg celebrated his 40th birthday in May, Musk said on X that he was still open to fighting him.

"If only Zuckerberg were as tough (sigh). I've offered to fight him any place, any time, any rules, but all I hear is crickets," Musk wrote in response to a satirical news story about a face-off between President Joe Biden and former President Donald Trump.

To be sure, Musk and Zuckerberg don't disagree on everything. For one, the feuding duo have similar approaches to competing in the AI space.

Both have repeatedly talked about building AI products that would break the stranglehold that big players like OpenAI and Microsoft have on the industry.

Musk also paid a rare compliment to Zuckerberg on Tuesday when Meta released its latest AI model, Llama 3.1. The open-source model, which Meta says can outperform OpenAI's GPT-4o, has been made available for the public to use for free.

"It is impressive and Zuck does deserve credit for open-sourcing," Musk wrote in an X post.

Representatives for Musk didn't immediately respond to a request for comment from BI sent outside regular business hours.
