Meta CEO Mark Zuckerberg has been spotted training with UFC champions Israel Adesanya and Alexander Volkanovski, fueling speculation about his rumored cage match with Elon Musk. A photo posted on Adesanya's Twitter account shows the trio together, captioned "This is Serious Business." This training session follows Zuckerberg's apparent agreement to fight Musk in a cage match, and Musk's own training with figures like Lex Fridman and Georges St-Pierre. While the potential fight has been generating buzz for weeks, UFC president Dana White has stated he would be willing to help produce the event, calling it potentially "the biggest fight ever." He also mentioned that both billionaires are "absolutely dead serious" about the bout. Despite the hype, concerns have been raised by Musk's father, Errol Musk, who believes the fight presents a "no-win situation" for his son, potentially labeling him a "bully" or a "loser" depending on the outcome. The rivalry between the two tech giants intensified recently with Musk resorting to personal attacks on Twitter, coinciding with the announcement of Meta's new app, Threads, reaching 100 million users.
