That rivalry has only increased in recent months, as Mr. Zuckerberg quickly spun up Threads after he witnessed the difficulties Mr. Musk had in his takeover of Twitter.
Their brinkmanship came to a head in June, when Mr. Musk, in a reply to someone on Twitter, said that he would fight Mr. Zuckerberg in a physical cage match.
It seemed as if the fight “might actually happen,” Mr. Musk later said in an online discussion.
In July, Mr. Zuckerberg posted a photo of himself shirtless after a training match, boasting a newly chiseled physique and affirming his zeal for the sport.
Mr. Musk did not respond to a request for comment.
