Mark Zuckerberg’s fortune plunged $20 billion as shares of Meta Platforms Inc. tumbled, allowing Tesla Inc.’s Elon Musk to cement his status as the world’s third-richest billionaire.
Meta shares fell as much as 16% Thursday in New York after the social media company said second-quarter sales were likely to come in below estimates. Zuckerberg’s one-day drop in net worth is the fourth-largest ever related to a stock move among those in the Bloomberg Billionaires Index, with his fortune now at $155 billion. Musk, 52, gained $400 million in wealth to $178 billion as Tesla stock continued its post-earnings rally.
The two billionaires switched ranks earlier this month, when Zuckerberg, 39, overtook Musk for the first time since 2020 following news that Tesla’s vehicle deliveries fell in the three months through March.
Shares of Menlo Park, California-based Meta fell Thursday by the most since October 2022 after the company increased spending estimates for the year and projected second-quarter sales that were below Wall Street’s expectations, once again raising questions about whether its bets on artificial intelligence will eventually pay off for investors.
The stock is still up 22% for the year and has been trading near all-time highs for the past month, in part reflecting excitement around AI.
