Global billionaire wealth hit a record $15.1 trillion in 2025, driven largely by an artificial intelligence investment boom. According to the Billionaire Census 2026 published by wealth intelligence firm Altrata, the billionaire population grew 8.2% to 3,795 individuals, with aggregate fortunes swelling 12.8% as AI-exposed companies significantly outperformed their peers in market capitalization growth.
The surge in wealth isn’t evenly distributed. While the total number of billionaires has climbed—marking the largest annual jump in five years and capping a decade in which the billionaire class grew by nearly 60%—the gains are increasingly concentrated at the absolute top of the pyramid. This trend has created a new class of superbillionaires, individuals whose personal fortunes now exceed $50 billion.
The Rise of the Superbillionaire Class
The concentration of wealth has reached new extremes. Altrata identified 29 individuals who fit the superbillionaire criteria, holding a combined $4.1 trillion. This group represents 27.2% of all billionaire wealth, a massive shift from 2017, when only 10 people cleared the $50 billion threshold and held just 7.2% of the total billionaire pool.
Much of this acceleration is tied to the AI boom. Among 150 publicly listed companies that drove the most gains for the wealthy, those that invested at least $30 million in AI over the last five years saw their market capitalizations grow 23% faster than companies that didn’t, between 2024 and 2025.
However, this growth is precarious. Maya Imberg, head of thought leadership and analytics at Altrata, warns that wealth built on AI-exposed tech stocks is prone to volatility. We expect the fortunes of many of the richest billionaires, those whose companies are tech-focused, to go up and down in response to the AI story,
Imberg said via email.
The reality of this volatility manifested in sharp market swings, including a $1.3 trillion selloff in major chip stocks in July. For the ultra-wealthy, these shifts result in massive paper losses; reports indicate Elon Musk suffered an $18 billion one-day drop, while Larry Ellison saw a $50 billion plunge over a single week, according to Forbes.
Regional Growth and Market Anomalies
North America remains the global epicenter of billionaire wealth, housing 1,337 people. The region also posted the fastest growth rate globally at 11.6% in 2025, a trend Imberg attributes to U.S. dominance in both public and private tech markets.
- Europe: 1,081 billionaires, following a 7.9% increase.
- Asia: 881 billionaires, representing a 6.5% rise.
The year 2025 was characterized by an unusual market alignment. Despite the turbulence caused by U.S. President Donald Trump’s trade war, every major asset class tracked by Altrata delivered positive returns—the first time this has occurred since the pandemic era.
This broad growth masks a deeper divergence in general personal wealth. While Altrata focuses on the top tier, a separate UBS analysis found that while global personal wealth grew 10.8% in 2025, median wealth actually declined in most countries even as average figures rose.
The $6.6 Trillion Generational Transfer
Beyond the immediate gains from AI, a massive structural shift in wealth is beginning. Over the next decade, an estimated $6.6 trillion in billionaire wealth will be passed on to nearly 5,000 direct heirs, including spouses and adult children.
Women are expected to be primary beneficiaries of this transfer, accounting for 90% of spousal heirs. This represents a movement of capital, shifting trillions from the founders of the AI and tech booms to the next generation.
The risk for these heirs, and the current holders of the wealth, remains the extreme concentration of assets. As Imberg notes, Market concentration doesn't necessarily mean it's a bubble. But there's certainly risk when exposure is concentrated within one main sector (tech), and to AI within that.
With total billionaire wealth now equaling roughly a quarter of the total market capitalization of the S&P 500 in 2025, the global economy is increasingly tethered to the performance of a very small group of tech-centric individuals.
