Additional $500 billion to fortunes: how much American tech billionaires earned in 2025 thanks to artificial intelligence

US technology leaders significantly increased their wealth in 2025 due to the boom around artificial intelligence. The combined fortunes of American tech billionaires grew by more than $550 billion as investors actively poured funds into companies associated with AI development.

According to data from the Financial Times, at the end of last year, the ten wealthiest technology founders and executives in the U.S. held assets worth nearly $2.5 trillion, which marks significant growth compared to the beginning of the year, when this amount was about $1.9 trillion. Major investments focused on AI chips, data centers, and artificial intelligence-based products.

Elon Musk remains a leading figure in the tech sector, with his wealth increasing by nearly half to $645 billion. This achievement was made possible by a record $1 trillion compensation deal at Tesla and the rapid capitalization growth of SpaceX to $800 billion.

Aside from Musk, significant growth was noted by Jensen Huang, founder of NVIDIA. His company became the world’s most valuable public stock, valued at over $4 trillion, with Huang’s personal fortune rising to $156 billion.

Jeff Bezos of Amazon sold shares worth $5.6 billion, and Michael Dell sold over $2 billion. Mark Zuckerberg from Meta dropped in the rankings due to a decline in the company’s shares, driven by spending on AI infrastructure.

Larry Ellison from Oracle profited from a $300 billion deal with OpenAI, though Oracle shares later declined due to funding questions regarding the project. Meanwhile, Larry Page and Sergey Brin from Google significantly increased their wealth thanks to advancements in AI technologies.

Bill Gates turned out to be the only tech billionaire whose fortune decreased, as he continues to invest in philanthropy by selling Microsoft shares.
