Mark Zuckerberg has said he is moving on from a rumoured cage fight with Elon Musk, claiming the Tesla founder “isn’t serious”. The rival billionaire tech bosses seemingly agreed to a brawl in June when Mr Musk tweeted that he was “up for a cage fight”. Mr Zuckerberg, who manages Facebook and Instagram, took a screenshot of Mr Musk’s tweet, replying “send me location”. However, on Sunday he said on social media platform Threads:”I think we can all agree Elon isn’t serious and it’s time to move on. “I offered a real date. Dana White (UFC boss) offered to make this a legit competition for charity. “Elon won’t confirm a date, then says he needs surgery, and now asks to do a practice round in my backyard instead. “If Elon ever gets serious about a real date and official event, he knows how to reach me. Otherwise, time to move on. I’m going to focus on competing with people who take the sport seriously.” Mr Musk, owner of social media platform X, formerly named Twitter, appeared to suggest the fight would be held in an “epic location” in Italy. He outlined streaming options and an ancient setting for the proposed event, claiming he had spoken to Italian Prime Minister Giorgia Meloni. Tensions have been high between the two tech billionaires’ companies after the launch of Threads, a text-based conversation app, by Mr Zuckerberg’s Meta in July. Twitter sent a cease-and-desist letter to Mr Zuckerberg after the launch, claiming Meta had made “unlawful misappropriation of Twitter’s trade secrets and other intellectual property”. Mr Zuckerberg is trained in mixed martial arts, posting about completing his first jiu jitsu tournament earlier this year. Mr Musk said last week he was training for the fight by lifting weights. He wrote on X: “Don’t have time to work out, so I just bring them to work.” Read More Elon Musk reveals more dramatic details of fight against Mark Zuckerberg UFC boss in talks to stage Musk vs Zuckerberg at Roman Colosseum Zuckerberg says he is ‘ready today’ but ‘not holding breath’ for cage fight with Musk Mark Zuckerberg reveals his 4,000 calorie diet and large McDonald’s order Meta’s Twitter rival Threads sees ‘steep drop in daily users by 80 per cent’ Vote to empower autonomous ‘robotaxis’ from Cruise and Waymo divides San Francisco
