The 0.00005% Club: How Fewer Than 4,000 People Now Hold Nearly Half the U.S. Economy

 The 0.00005% Club: How Fewer Than 4,000 People Now Hold Nearly Half the U.S. Economy

**The world's billionaire population hit a record 3,795 in 2025, and their combined wealth surged 12.8% to an unprecedented $15.1 trillion. That's nearly half the size of the entire U.S. economy and almost 30% of the combined GDP of all G7 nations. And at the very top, just 29 "superbillionaires" control over a quarter of all that wealth. The driver behind this historic concentration? One word: AI.**

## The Number That Defies Comprehension

Let me put this in perspective. Out of a world of more than 8 billion people, billionaires make up a sliver so thin it barely registers: about **0.00005%** — roughly one in every two million people alive today.

That's fewer than the number of students at a typical college. It's about one-fifth of a full house at Madison Square Garden, a tenth of Yankee Stadium.

And yet, that microscopic group now holds **$15.1 trillion** in combined wealth.

To help you wrap your head around that number: $15.1 trillion is **close to half the size of the entire U.S. economy**, which sits at $32.5 trillion. It's **nearly 30% of the combined GDP of all G7 nations**. It's equivalent to about a quarter of the total market capitalization of the S&P 500.

## The AI Engine

So what's driving this explosion of wealth at the very top? According to Maeen Shaban, Altrata's director of research and analytics and lead author of the Billionaire Census 2026, the answer is clear: **artificial intelligence**.

Altrata dug into 150 publicly listed companies that carry the most weight in billionaire wealth. The companies that made big AI bets grew their market value **23% faster** than the ones that didn't. That gap shows up directly in billionaire bank accounts. When a company's stock climbs, so does the net worth of the people who own big chunks of it.

Semiconductors, data centers, cloud infrastructure — the entire ecosystem around AI is minting new fortunes. Over the past decade, the global billionaire population has grown by roughly 60%. And the pace is accelerating: the billionaire population grew **8.2% in 2025 alone**, the fastest growth in five years.

## The Superbillionaire Explosion

Here's where it gets even more staggering. Not all billionaires are created equal. There's a smaller, more exclusive club: the "superbillionaires" — people worth more than **$50 billion each**.

In 2025, there were **29** of them. Together, they control **$4.1 trillion**. That's **27% of all billionaire wealth** on the planet — held by less than 1% of billionaires.

Rewind to 2017. Back then, there were only 10 superbillionaires. They held just **7.2%** of total billionaire wealth. In eight years, their numbers tripled. Their share of the pie nearly quadrupled.

Most of that rise has come in the last two years alone. The share stood at just 16.3% as recently as 2023.

The names at the top of that list are familiar: Elon Musk, Larry Page, Sergey Brin, Jeff Bezos, Larry Ellison, Mark Zuckerberg, Jensen Huang, and Warren Buffett dominate the rankings. But the list is growing — and fast.

## The North America Dominance

North America remains the billionaire capital of the world. The region added the most new billionaires of any region, growing **11.6%** to reach 1,337. Europe came next, up 7.9% to 1,081. Asia grew more slowly, up 6.5% to 881.

The United States alone holds 979 billionaires, according to Forbes. Fifteen of the world's top 20 highest-earning individuals are American. U.S. billionaire wealth now hits roughly **$8.2 trillion** — over a quarter of the nation's GDP.

## The Coming Wealth Transfer

Here's another mind-bending statistic: Altrata estimates that **$6.6 trillion of billionaire wealth will be passed on over the coming decade**. Thousands of spouses and adult children are expected to receive substantial inheritances.

For family offices, the implications extend far beyond estate planning. Transitions of this scale can affect investment objectives, governance, philanthropy, risk appetite, and the role of the next generation in family decision-making.

The challenge for families that have created exceptional wealth is not only how to generate further returns. It's how to establish governance and investment structures capable of managing concentrated assets, changing family priorities, and transfers of ownership over several generations.

## Paper Wealth vs. Real Wealth

There's a catch to all this new wealth. Most of it isn't cash sitting in a bank. It's **paper wealth** — tied to stock prices that can move in a day.

Maya Imberg, head of research at Altrata, expects billionaire fortunes tied to tech to rise and fall along with AI market sentiment. When a company's stock climbs, so does the net worth of the people who own big chunks of it. When it falls, that wealth evaporates just as quickly.

This is what makes the current moment both extraordinary and precarious. The same AI boom that's minting billionaires could also unwind them if the market turns. But for now, the trend is unmistakable: wealth is concentrating at the top faster than at any point in modern history.

## What This Means for Everyone Else

The numbers are sobering. A group smaller than your college graduating class now holds nearly half the economic output of the United States. Twenty-nine people control more wealth than the bottom 60% of the world's population.

The AI boom has been a tremendous engine of wealth creation. But it's also been a tremendous engine of wealth concentration. The companies making big AI bets grew their market value 23% faster than the ones that didn't. That gap shows up directly in the bank accounts of the people who own those companies.

Maeen Shaban, Altrata's director of research, points to one cause above the rest: artificial intelligence. And there's no sign of that trend slowing down. The billionaire population is growing at its fastest pace in five years. The superbillionaire share has more than tripled since 2017.

Whether you see this as a triumph of innovation or a warning sign of deepening inequality, one thing is clear: we are living through an unprecedented concentration of wealth, and the AI revolution is the engine driving it.
