Well, no one was expecting this: Meta CEO Mark Zuckerberg wants to literally fight Tesla CEO Elon Musk in a cage match. 

How did this happen? It all started on Tuesday night when Musk responded to a tweet about how Zuckerberg is preparing to release a rival social media platform, called Threads, to best Twitter. 

Musk is no fan of Zuckerberg; he’s previously taken several jabs at Facebook’s founder over their different approaches to privacy and AI. On Tuesday, Musk hurled another insult. 

“I’m sure Earth can’t wait to be exclusively under Zuck’s thumb with no other options,” he wrote, referencing Zuckerberg’s already vast influence over the social media market. 

A Twitter user then told Musk: “Better be careful... I heard he (Zuckerberg) does the ju jitsu now.”

To that, Musk wrote: “I’m up for a cage match if he is lol.”

Musk's tweet may have been a joke. But even so, Zuckerberg saw it and had to respond. On his Instagram account, the Facebook founder posted a screenshot of Musk’s tweet. Then beneath it, he wrote the words: “Send Me Location.”

The Instagram Stories post from Zuckerberg

Zuckerberg really has been training in Brazilian jiu-jitsu. He’s posted several pictures and videos on Instagram showing him practicing with professional trainers. Last month, he also boasted, “competed in my first jiu jitsu tournament and won some medals.” (He also lost one match.)

So Zuckerberg is probably feeling confident he can choke out Musk in the ring. The craziest part is that the bout could actually happen. “Vegas Octagon,” Musk tweeted in response to the news about Zuckerberg accepting the challenge. 

At the same time, Musk has made several tweets, indicating he’s treating the fight as more of a joke. “I have this great move that I call ‘The Walrus,’ where I just lie on top of my opponent and do nothing,” he wrote in one tweet. “I almost never work out, except for picking up my kids and throwing them in the air,” he later added

Still, if the match does happen, it’ll grab headlines, to say the least. Obviously, it won’t be Ali vs. Frazier, the 1971 "Fight of The Century" between two of the greatest boxers. But a bout between Zuckerberg and Musk —two of America’s most famous and notorious tech CEOs—is bound to amuse and epitomize the weirdness of our own century.

My Experience

I've been a journalist for over 15 years. I got my start as a schools and cities reporter in Kansas City and joined PCMag in 2017, where I cover satellite internet services, cybersecurity, PC hardware, and more. I'm currently based in San Francisco, but previously spent over five years in China, covering the country's technology sector.

Since 2020, I've covered the launch and explosive growth of SpaceX's Starlink satellite internet service, writing 600+ stories on availability and feature launches, but also the regulatory battles over the expansion of satellite constellations, fights with rival providers like AST SpaceMobile and Amazon, and the effort to expand into satellite-based mobile service. I've combed through FCC filings for the latest news and driven to remote corners of California to test Starlink's cellular service.

I also cover cyber threats, from ransomware gangs to the emergence of AI-based malware. In 2024 and 2025, the FTC forced Avast to pay consumers $16.5 million for secretly harvesting and selling their personal information to third-party clients, as revealed in my joint investigation with Motherboard.

I also cover the PC graphics card market. Pandemic-era shortages led me to camp out in front of a Best Buy to get an RTX 3000. I'm now following how the AI-driven memory shortage is impacting the entire consumer electronics market. I'm always eager to learn more, so please jump in the comments with feedback and send me tips.

The Best Tech I've Had:

  • My first video game console: a Nintendo Famicom
  • I loved my Sega Saturn despite PlayStation's popularity.
  • The iPod Video I received as a gift in college
  • Xbox 360 FTW
  • The Galaxy Nexus was the first smartphone I was proud to own.
  • The PC desktop I built in 2013, which still works to this day.
