Billionaire Wealth Hits Record $15.1 Trillion on AI Investment Boom

The global billionaire population grew by 8.2 percent in 2025 to a record 3,795 people, while their combined wealth rose 12.8 percent to a record $15.1 trillion. That marks the fastest annual growth in the number of billionaires in five years, and according to analytics firm Altrata, the main driver is the investment boom around artificial intelligence.

What the Report Shows

The Billionaire Census 2026, compiled annually by Altrata's wealth intelligence unit, is one of the most widely cited surveys of the world's wealthiest people's fortunes. This year's thirteenth edition covers data for 2025 and shows the strongest increase in the number of billionaires in five years, with their population growing by nearly 60 percent over the past decade.

The report's authors point directly to technology as the driver of this growth. Among 150 large public companies analyzed for their impact on billionaire fortunes, those with significant AI investments grew markedly faster than the rest of the market, by 23 percent between 2024 and 2025. The effect is visible in the valuations of companies working in foundation models, cloud computing, robotics and cybersecurity, which Altrata says have created an entirely new wave of billionaires.

A Narrowing Top Tier

The report's most striking finding is the growing concentration of wealth at the very top of the pyramid. A group of 29 so-called super-billionaires, people with fortunes exceeding $50 billion, now controls $4.1 trillion, 27.2 percent of all billionaire wealth worldwide. By comparison, in 2017 that same group numbered just 10 people and accounted for 7.2 percent of the category's wealth.

The rest of the pyramid looks very different. As much as 46 percent of the global billionaire population falls into the lowest wealth bracket, with 1,753 people holding fortunes between $1 billion and $2 billion, and another 1,339 between $2 billion and $5 billion. In other words, a record number of billionaires does not mean the group is getting richer evenly, but rather that the fortunes of the few at the very top are growing even faster.

Market concentration doesn't necessarily mean a bubble. But there is a clear risk when exposure is concentrated in one dominant sector, technology, and within that, further concentrated in AI - Maya Imberg, head of research and thought leadership at Altrata

One Trillionaire and Soaring Valuations

The report also cites an episode that became a symbol of this year's AI-driven wealth surge: in mid-2026, Elon Musk briefly became history's first trillionaire following SpaceX's stock market debut. Altrata's authors treat the moment as an illustration of how concentrated valuations in the AI sector translate into the individual fortunes of single founders and investors.

The phenomenon isn't limited to publicly traded tech giants. More than 1,300 AI startups are already valued at $100 million or more, and nearly 500 so-called AI unicorns have a combined value of around $2.7 trillion, showing that new fortunes are being made both on public markets and in private venture capital.

Effects for Everyday Investors and the Polish Perspective

The concentration of wealth in a handful of AI-linked companies matters beyond the rich lists. Since it is precisely the tech megacaps and high-profile private debuts pulling the S&P 500 upward, their gains and losses feed directly into the performance of pension and investment funds in which Polish savers are also indirectly invested.

Against the backdrop of the global AI billionaire wave, Poland's wealthiest look very different. According to the latest Forbes Poland list, the country is home to 11 billionaires with a combined wealth of about $39 billion, and the top of the ranking of Poland's 100 richest people is led by Michał Sołowow (chemicals, Synthos), Tomasz Biernacki (the Dino retail chain) and Jerzy Starak (Polpharma), none of whom owe their fortunes directly to AI investment. That shows the boom described by Altrata has, for now, almost entirely bypassed the Polish capital market.

The report's authors also estimate that over the next decade, about $6.6 trillion in billionaire wealth will pass by inheritance to roughly five thousand heirs, which, given the current pace of wealth concentration around AI technology, could deepen wealth disparities in the next generation even further.
