Right now, Elon Musk has to deal with a spell of reality with respect to his great wealth. In Q1, however, it saw the evaporation of $116 billion from its net worth. At the end of March, what was left was still $316 billion, but that drop mostly traces back to Tesla's tough start to the year: the EV giant posted its worst-ever quarterly vehicle delivery numbers, which spooked investors and sent the stock into a big downturn.

Jeff Bezos didn’t escape the sell-off either, as his fortune shrank by $27.1 billion, dropping him to $212 billion. Meanwhile, Mark Zuckerberg saw a $3.35 billion decline, both losses driven by the tech slide, with the Nasdaq falling 12 percent in just three months.

The loss with tech billionaires seemed to be a gain for a few in the opposite direction. Warren Buffett saw an increase of $24.3 billion, reaching $166 billion, thanks to Berkshire Hathaway’s stock performance. Bill Gates made $2 billion reluctantly. On the other hand, Bernard Arnault saw his wealth drop by 20% as luxury stocks were battered by tariff concerns and weakening demand.

At the end of the day, this quarter was a reminder that tech fortunes can swing hard. The first quarter of 2025 was costly for Musk, Bezos, and Zuckerberg.
