AI Boom Drives Over $0.5 Trillion Increase in Wealth of US Tech Billionaires in 2025
The AI-driven rally in the stock market has significantly increased the wealth of US tech billionaires by more than $0.5 trillion in 2025, bringing the combined net worth of the top 10 US technology founders and executives to nearly $2.5 trillion, up from $1.9 trillion according to Bloomberg.
Elon Musk's net worth surged approximately 50% year-on-year to reach $645 billion, making him the first person to surpass $500 billion in October. He remains the richest, ahead of Google co-founder Larry Page at around $270 billion and Amazon founder Jeff Bezos at $255 billion. Musk could become the world's first trillionaire if Tesla meets its future targets.
Nvidia CEO Jensen Huang saw his fortune increase by $41.8 billion to $159 billion, ranking ninth on the Bloomberg Billionaire Index and eighth among the top US tech billionaires. Huang sold nearly $1 billion in shares this year, with Nvidia becoming the world's first company to hit a $5 trillion market capitalization in October, underscoring the critical role of AI chips in driving wealth among technology magnates.
Larry Page and Sergey Brin's wealth also grew substantially by about $102 billion and $92 billion respectively, with investments including Google's development of in-house AI chips such as the Tensor Processing Unit.
Outside of the tech sector, other billionaires experienced notable gains as well. Bernard Arnault's wealth rose by $28.5 billion in 2025; he controls around half of LVMH. Meanwhile, Amancio Ortega's fortune increased by $34.3 billion to $136 billion, boosted by a record €3.1 billion dividend from Inditex.
Despite these gains, the Bank of England has issued cautionary remarks about a potential "sudden correction" in global markets if investor confidence weakens. Valuations appear stretched for technology-focused AI stocks, and markets remain vulnerable should optimism around AI's impact diminish.
