Five of the world's wealthiest technology executives have seen a combined $198 billion wiped from their net worths since January, according to the Bloomberg Billionaires Index. The dramatic decline is driven by a cooling of investor enthusiasm for artificial intelligence (AI) and a broader market sell-off triggered by geopolitical tensions in the Middle East.
Larry Ellison, co-founder and chief technology officer of Oracle, has suffered the most significant loss, with his personal fortune shrinking by approximately $60 billion. His wealth stood at $188 billion at Friday's close, a sharp drop from a peak near $400 billion in September 2023, when he briefly surpassed Elon Musk as the world's richest person.
The plunge is directly linked to Oracle's stock price, which has fallen nearly 30% this year. Investors have grown sceptical of the enterprise-software giant's debt-fuelled expansion of AI data centres.
Meta and Amazon Founders See Major Declines
Meta Platforms co-founder and CEO Mark Zuckerberg has seen his wealth reduced by $46 billion to $187 billion. Shares in the parent company of Facebook, Instagram, and WhatsApp have tumbled 20% amid legal challenges and growing doubts over its substantial AI investment plans.
Amazon founder Jeff Bezos and Alphabet co-founders Larry Page and Sergey Brin have also seen substantial declines. Their respective net worths have fallen by about $31 billion, $32 billion, and $29 billion year-to-date, reflecting stock price drops of around 14% for Amazon and 12% for Alphabet.
Geopolitical Unrest Fuels Global Market Retreat
The wealth destruction extends beyond the core tech sector. Former Microsoft CEO Steve Ballmer is down $41 billion, while LVMH founder Bernard Arnault has lost almost $58 billion due to a 29% fall in the luxury conglomerate's stock.
This coincides with a broad sell-off in world stocks, intensified by the conflict involving Iran, Israel, and the United States. The virtual closure of the Strait of Hormuz—a critical route for global oil and liquefied natural gas shipments—has spiked crude prices, pressured consumers, eroded growth forecasts, and dampened expectations for swift interest rate cuts.
AI Bubble Concerns and the Current Rich List
The recent declines follow years of soaring tech valuations fuelled by excitement over AI's potential to revolutionise productivity and profits. However, prominent sceptics like investor Michael Burry, famed for predicting the 2008 financial crisis, have warned the sector is in a bubble characterised by excessive valuations and overbuilding.
Despite the losses, Page, Bezos, Brin, Ellison, Zuckerberg, and Arnault still rank second to seventh on Bloomberg's rich list. Elon Musk retains the top spot with a $17 billion gain this year to $637 billion, driven by the rising valuations of his private companies SpaceX and xAI, despite Tesla's stock being down 20%.
