AI boom lifts global billionaire wealth to record $15.1 trillion

The combined wealth of the world's billionaires climbed to a record $15.1 trillion in 2025, surpassing the $15 trillion mark for the first time as the artificial intelligence investment wave lifted technology stocks and minted hundreds of new ultra-rich individuals, according to a report published by wealth intelligence firm Altrata.cnbc+1

The Billionaire Census 2026, released in late August, found that the global billionaire population rose 8.2 percent over the year to 3,795 people — an increase of 287 individuals and the strongest annual growth in five years. Their collective net worth grew even faster, rising 12.8 percent, which Altrata said now amounts to roughly a quarter of the total market capitalization of the S&P 500.qz+3

AI as the Engine of Wealth

The report pointed to AI-related investment as a central driver. Among the 150 publicly traded companies that contributed most to billionaire wealth creation, those that committed at least $30 million to AI development over the preceding five years achieved 23 percent faster market capitalization growth between 2024 and 2025 than peers that did not make comparable investments. The rally in semiconductors, enterprise software, and computing infrastructure translated directly into equity gains for founders and major shareholders.the420+1

Wealth Concentrates at the Top

The gains were not evenly distributed. Altrata identified 29 "super billionaires" with fortunes exceeding $50 billion. That group, representing just 0.8 percent of all billionaires, controlled $4.1 trillion — roughly 27 percent of total billionaire wealth. In 2017, only 10 individuals met that threshold, and they held just 7.2 percent of the global total.sedaily+1

Regionally, North America led with 1,337 billionaires after an 11.6 percent increase, followed by Europe at 1,081 (up 7.9 percent) and Asia at 881 (up 6.5 percent). The average billionaire age stood at 71, with women making up only 13 percent of the cohort.nairametrics+2

Fragility Warning

Altrata cautioned that the concentration in technology holdings creates vulnerability. Maya Imberg, the firm's head of thought leadership and analytics, warned that fortunes tied to AI "could swing sharply in response to market adjustments or evolving investor sentiment," and that any slowdown in corporate capital expenditure or downward revisions in valuations could trigger rapid declines across technology-heavy portfolios.scrippsnews+1
