Once again, the wealthiest man on earth has created havoc on the internet with his tweets.

In a tweet late on Tuesday, Tesla’s billionaire CEO Elon Musk announced that he was acquiring Manchester United.

“Also, I’m buying Manchester United; ur welcome,” Musk told his 103 million Twitter followers.

Following several news articles about Musk’s bold claim, Musk clarified that it was all a joke.

“No, this is a long-running joke on Twitter. I’m not buying any sports teams,” he replied to a user after being asked if he was serious.

When asked about Musk’s tweet, a Manchester United (MANU) spokesperson said, “we do not comment on rumors and speculation.”

Forbes estimates Manchester United’s value at $4.6 billion. Owned by the Glazer family, owners of the NFL team Tampa Bay Buccaneers, Manchester United ranks among the top soccer clubs worldwide. However, it hasn’t won the English Premier League title since 2013.

In his 13 years on Twitter, the platform has become essential to Musk’s brand. On it, he discusses his business ventures, lashes out at people he views as detractors, provides market commentary on cryptocurrencies, and shares the occasional meme.

His 2019 tweet even joked: “Some people use their hair to express themselves. I use Twitter.”

However, Musk’s tweets about Tesla have landed him in trouble with the Securities and Exchange Commission several times. His feud with the SEC dates back to his now-infamous 2018 tweet stating, “Am considering taking Tesla private at $420. Funding secured.”

The nine-word tweet sent Tesla stock soaring at the time, but the SEC accused him of misleading investors later. Musk and regulators eventually reached a deal that included, among other provisions, a requirement that Musk gains pre-approval from other Tesla executives before tweeting about the company.

The billionaire’s tweets regarding Manchester United come when he is trying to terminate his $44 billion acquisition of the social platform. Twitter has taken him to court over his attempt to exit the deal.
