The five billionaires who 'cried' this week – How much did Musk, Bezos and Zuckerberg lose in one day?

The combined fortunes of five tech CEOs took a $26 billion hit in a single day. Last Thursday, the massive sell-off in AI stocks “impoverished” the world's billionaires, who saw some of their wealth evaporate.

The combined fortunes of five tech CEOs dropped $26 billion in a single day on Thursday, according to the Bloomberg Billionaires Index. They are Elon Musk, Mark Zuckerberg, Jeff Bezos, Jensen Huang and Michael Dell, the Greek press writes.

Their wealth shrank as their respective shares in Tesla, Meta, Amazon, Nvidia and Dell fell in value. Share prices of the top four companies fell about 2 percent on Thursday as investors expressed concern about the enormous cost of building artificial intelligence infrastructure and whether they will eventually see a return on their spending.

Shares in Dell fell 9 percent after rival Lenovo warned that a shortage of memory chips was driving up costs, sparking concerns on Wall Street that other manufacturers' profits could also shrink. The stock crash wiped $5 billion from the company's founder's fortune.

But the blow was bigger for Elon Musk, whose fortune fell by more than 8 billion dollars on Thursday. However, the Tesla and SpaceX CEO is still up about $57 billion this year thanks to the rising valuations of SpaceX and another of his companies, xAI.

Mark Zuckerberg lost nearly $7 billion in a single day, while Jeff Bezos lost $4 billion and Jensen Huang $2.5 billion.

Other tech executives also posted losses. Alphabet co-founders Larry Page and Sergey Brin lost about $1.5 billion, with shares of Google's parent company down less than 1 percent.

Instead, Walmart shares rose nearly 4 percent to a record high on Thursday as worries about tariffs eased. The stock surge added more than $4 billion to the fortunes of founder Sam Walton's three children: Jim, Rob and Alice.
