How many students made up your college cohort? Odds are its about 4,000—the same, if not more, than the total number of billionaires on earth. Think about the last time you went to a sports stadium, to a concert venue, or even visited a small coastal town ahead of the fall holidays.
The fewer-than 3,800 billionaires worldwide make up just one-fifth of a full house at MSG, a tenth of Yankee Stadium, and the population of your average New England town. And out of a world of more than 8 billion people, they make up a sliver so thin it barely registers: about 0.00005%, or one in every two million people alive today. And yet, that sliver holds a record $15.1 trillion, according to Altrata’s Billionaire Census 2026.
This wealth is close to half the size of the entire U.S. economy ($32.5 trillion) and nearly 30% of the combined GDP of the G7 nations ($52.06 trillion). The population grew 8.2% in 2025, the fastest pace in five years, but wealth distribution remains uneven. Twenty-nine people now hold fortunes above $50 billion, dubbed superbillionaires, and they control $4.1 trillion, or 27.2% of all billionaire wealth.
This rise has been rapid, with the share of superbillionaire wealth increasing from 16.3% in 2023 to 27.2% in 2025. Key figures like Elon Musk, Larry Page, Sergey Brin, Jeff Bezos, Larry Ellison, Mark Zuckerberg, Jensen Huang, and Warren Buffett dominate the list. Maeen Shaban, Altrata’s director of research and analytics, attributes this growth to artificial intelligence.
Companies investing in AI since 2023 saw a 23% increase in market cap growth over 2024 and 2025. However, Shaban cautions that the number is complex, as some billionaires built AI companies while others used AI to cut costs elsewhere. Geographically, New York gained 12 billionaires in 2025, bringing the total to 164, while Singapore and San Francisco also saw growth.
Hong Kong and London were the only top cities to lose billionaires. The San Francisco Bay Area reportedly hosts six of the world’s richest people. In Germany, wealth is more distributed, with no German city ranking among the top 15.
About one-fifth of billionaires are foreign-born, with higher proportions in Singapore and London. The article also discusses the Great Wealth Transfer, with Altrata estimating billionaires will pass $6.6 trillion to spouses and children over the next decade. Shaban notes that more than 60-70% of billionaires are self-made, attributing future growth to entrepreneurship rather than inheritance.
The ultra-wealthy population grew seven times faster than the world’s adult population between 2005 and 2025, and Altrata projects that by 2040, 70% of the ultra-wealthy will be new entrants.
