Musk isn’t serious about fighting, Zuckerberg says. Here’s the latest.

The seeds of the proposed fight between billionaire tech entrepreneurs Elon Musk and Mark Zuckerberg were sown with a joke.

After Musk, Twitter’s owner, commented about Zuckerberg’s social media app Threads, one of Musk’s social media followers jokingly warned him that Zuckerberg knows jujitsu.

The two never held a public conversation about the physical battle, but they spoke to each other through the social media apps they lead — Musk on the recently rebranded X and Zuckerberg on Threads and Instagram — baiting each other into what Musk called a “cage match.” Zuckerberg replied: “Send Me Location.”
