Youngest billionaires globally 2026, by net worth

Youngest billionaires in the world as of June 2026, based on net worth

The youngest billionaire in the world in 2026 is Amelie Voigt Trejes, a 20-year-old heir to the Brazilian electric-motor maker WEG, worth about 1.1 billion dollars. A record 35 billionaires are under 30, worth about 92 billion dollars between them, of whom a record 12 are self-made. The list of the youngest billionaires in the world offers a striking portrait of how great wealth reaches the very young, whether through inheritance of a great family fortune or, increasingly, through the soaring valuations of a technology startup founded in the founders early twenties. On the 2026 Forbes list, the 35 billionaires under 30 are worth about 92 billion dollars between them, an average of more than 2.5 billion each, though the range runs from about 1 billion for the youngest heirs to nearly 7 billion for the richest. Few lists capture the changing face of great wealth as vividly as the ranking of the youngest billionaires, where the old world of inherited family fortunes meets the new world of self-made technology founders barely out of university.

Most of the youngest billionaires inherited their fortunes, but a growing number are self-made, led by young founders in artificial intelligence. The ranking builds on our most affluent women and age distribution of billionaires coverage.

A record number: a record 35 billionaires are under 30 in 2026, up from 30 in 2025, though their combined wealth fell to about 92 billion dollars from 152 billion.

The under-30 billionaires make up about 1 percent of the world 3,428 billionaires, and their number has grown as huge technology funding rounds and family inheritances have minted more young billionaires, themes our billionaires by gender and richest people in America coverage explores.

A note on the data. The figures show the youngest billionaires in the world as of 2026, based on net worth, from the Forbes World Billionaires list. They are based on the 35 billionaires under age 30 on the 2026 list, and the figures change with the markets. Because the list is drawn from the annual Forbes ranking and net worths change with the markets, the exact figures and even the order of the youngest billionaires shift over time, but the broad picture, of a young rich still led by heirs, is stable. The youngest billionaires are identified from the annual Forbes World Billionaires list, which records the age of each billionaire, and the net worth figures are the 2026 values, which change with the markets and with company valuations.

The Youngest Billionaires in the World

The table lists the youngest billionaires in the world in 2026 by age and net worth. It shows a mix of young heirs to great family fortunes and a growing group of self-made founders, most of them in artificial intelligence and prediction markets. Reading down the table shows the two faces of young wealth side by side, the 20-year-old heirs to industrial and pharmaceutical fortunes and the 22-year-old founders of artificial-intelligence startups, each having reached the billion-dollar mark in a very different way. Because private company valuations and share prices move, the exact net worths of the youngest billionaires, especially the self-made founders whose wealth is tied to fast-growing startups, can change sharply from one funding round to the next.

Who Is the Youngest Billionaire in the World?

The youngest billionaire in the world is Amelie Voigt Trejes, 20, an heir to the Brazilian electric-motor maker WEG, worth about 1.1 billion dollars. She is seven weeks younger than the German pharmaceutical heir Johannes von Baumbach, also 20, worth about 6.4 billion. The fact that the world youngest billionaire is just 20 years old, with a fortune inherited through a family trust, captures the way great wealth can arrive before a person has even finished university, long before most people begin their careers. Amelie Voigt Trejes about 1.1 billion dollars comes from a 2 percent stake in WEG, the Brazilian electric-motor giant her grandfather cofounded, one of seven Voigt cousins on the list who share a combined fortune of about 9.5 billion. The image of a 20-year-old worth more than a billion dollars, whether through inheritance or a fast-growing startup, is a striking illustration of how unevenly wealth is distributed, and of how early it can arrive for a fortunate few.

The youngest billionaires are dominated by heirs to great family companies, from industrial machinery to pharmaceuticals and eyewear, who became billionaires young by inheriting large stakes, a pattern our billionaires around the world coverage frames.

Aged 20 and up: the youngest billionaire is Amelie Voigt Trejes at 20 on about 1.1 billion dollars, alongside the pharma heir Johannes von Baumbach, also 20, on 6.4 billion.

Behind the youngest two come a cluster of 21 and 22-year-olds, including the Italian eyewear heir Clemente Del Vecchio and the South Korean gaming heir Kim Jung-youn, alongside the self-made founders of the artificial-intelligence startup Mercor. The presence of several members of the same families, such as the Voigt cousins from Brazil and the von Baumbach siblings from Germany, reflects how great family fortunes can create several young billionaires at once when large stakes are passed down.

Who Are the Richest Young Billionaires?

The richest of the under-30 billionaires are the Italian brothers Clemente and Luca Del Vecchio, each worth about 6.8 billion dollars from their stakes in the eyewear group EssilorLuxottica, followed closely by the four von Baumbach siblings on about 6.6 billion each. The concentration of the largest young fortunes among heirs to great family companies shows that, for now, the biggest young billionaires are made by inheritance rather than by building a business, even as the self-made founders grab the headlines. Clemente and Luca Del Vecchio about 6.8 billion dollars each, from their stakes in the eyewear group EssilorLuxottica, make them the richest of the under-30s, ahead of the four von Baumbach siblings on about 6.6 billion each from the drugmaker Boehringer Ingelheim.

The dominance of heirs among the richest young billionaires shows how the largest young fortunes come from inheriting stakes in great family companies rather than building new ones, a pattern our biggest companies by market value coverage frames.

Heirs on top: the richest young billionaires are the eyewear heirs Clemente and Luca Del Vecchio on about 6.8 billion dollars each, and the von Baumbach siblings on 6.6 billion.

The richest self-made young billionaires, the founders of the artificial-intelligence startup Mercor, are worth about 2.2 billion dollars each, far less than the largest inherited fortunes but built entirely from scratch in just a few years. The gap between the largest inherited fortunes, worth close to 7 billion dollars, and the largest self-made young fortunes, worth about 2 billion, shows how far ahead inherited wealth remains even at the very top of the young billionaire list.

Self-Made or Inherited?

Most of the youngest billionaires inherited their wealth. Of the 35 under-30 billionaires in 2026, about 23 inherited their fortunes, while a record 12 are self-made, the highest number of self-made young billionaires ever recorded. The balance between inherited and self-made wealth among the youngest billionaires is one of the most revealing features of the list, showing that while inheritance still dominates, a record number of the young rich have built their own fortunes. With about 23 of the 35 under-30 billionaires having inherited their fortunes and a record 12 self-made, the young billionaire class remains dominated by heirs, though the self-made share, at about a third, is the highest ever. The tug-of-war between inherited and self-made wealth is nowhere clearer than among the youngest billionaires, where the record number of self-made founders sits alongside a still larger group of heirs to great family businesses.

The rise in self-made young billionaires reflects the huge funding rounds flowing into artificial-intelligence startups, which have created several very young self-made billionaires in the past year, a boom our sources of billionaire wealth coverage frames.

Mostly heirs: of the 35 under-30 billionaires, about 23 inherited their fortunes while a record 12 are self-made, the highest number ever.

Even so, inheritance remains the most common route to becoming a billionaire before 30, with most of the youngest billionaires holding large stakes in family companies in industrial machinery, pharmaceuticals, retail and eyewear. The enduring dominance of inheritance among the youngest billionaires is a reminder that, for all the attention paid to self-made technology founders, the surest route to great wealth before 30 remains being born into a family that already has it. Looking ahead, the share of self-made young billionaires seems likely to keep rising if the artificial-intelligence boom continues, though inheritance will remain the most common route to great wealth before the age of 30.

The Youngest Self-Made Billionaires

The youngest self-made billionaire in the world is Surya Midha, 22, who cofounded the artificial-intelligence recruiting startup Mercor with Brendan Foody and Adarsh Hiremath, also 22. Each is worth about 2.2 billion dollars, or roughly 100 million dollars for every year they have been alive. The rise of self-made billionaires still in their early twenties, above all the founders of artificial-intelligence startups, is one of the most remarkable features of the 2026 list, reflecting the extraordinary speed at which the technology boom is creating wealth. Surya Midha, Brendan Foody and Adarsh Hiremath, the founders of the artificial-intelligence recruiting startup Mercor, are each about 22 years old and worth about 2.2 billion dollars, having built their fortunes in just a few years. The emergence of self-made billionaires in their early twenties, unimaginable a generation ago, is one of the defining features of the current technology boom, which has compressed the path from startup to great fortune into just a few years.

The wave of very young self-made billionaires reflects the artificial-intelligence boom, which has lifted the founders of startups such as Mercor, Polymarket and Kalshi into the billionaire ranks in their twenties, a boom our Nasdaq stock market coverage frames.

Led by Mercor: the youngest self-made billionaire is Surya Midha, 22, of the AI startup Mercor, worth about 2.2 billion dollars, alongside his two cofounders.

Other young self-made billionaires include Shayne Coplan, the founder of the prediction market Polymarket, and Luana Lopes Lara of Kalshi, the youngest self-made woman billionaire, showing how prediction markets and artificial intelligence are minting young fortunes. The clustering of the youngest self-made billionaires in prediction markets and artificial intelligence, from Mercor to Polymarket and Kalshi, reflects how a handful of fast-growing sectors are minting young fortunes faster than anywhere else. Whether these very young self-made fortunes endure will depend on the fate of the startups behind them, since much of their wealth is tied to private valuations that could rise or fall sharply in the years ahead.

Which Industries Made Them Rich?

The youngest billionaires made their money in a wide range of industries. Technology and artificial intelligence account for the most, about eight of the 35, followed by industrial machinery, pharmaceuticals and finance, reflecting both new startups and old family firms. The range of industries behind the youngest billionaires, from artificial intelligence and prediction markets to eyewear, drugstores and electric motors, reflects the two very different routes to great young wealth, new startups and old family firms.

The prominence of technology and artificial intelligence among the youngest billionaires reflects the way huge funding rounds have created young self-made fortunes, while the family firms reflect inherited wealth, a mix our global stock markets by country coverage frames.

Technology leads: technology and artificial intelligence account for about eight of the 35 youngest billionaires, ahead of machinery, pharmaceuticals and finance.

Outside technology, the youngest billionaires are concentrated in the great family industries, from the electric motors of WEG and the eyewear of EssilorLuxottica to the pharmaceuticals of Boehringer Ingelheim and the drugstores of dm. The split between the technology startups that create self-made young billionaires and the family firms that create young heirs runs through the whole list, dividing the youngest billionaires into two very different groups.

Where the Youngest Billionaires Live

The youngest billionaires are concentrated in a few countries. The United States is home to about eight, all self-made, followed by Germany with about six and Brazil with five, mostly heirs to great family fortunes such as WEG and Boehringer Ingelheim. The geography of the youngest billionaires reflects the split between self-made and inherited wealth, with the United States producing self-made technology founders and Europe and Latin America producing heirs to great family companies. The United States about eight under-30 billionaires are all self-made, mostly in technology, while Germany six and Brazil five are mostly heirs, reflecting the very different sources of young wealth in each country. The map of the youngest billionaires traces the two engines of young wealth, the self-made technology fortunes of the United States and the inherited family fortunes of Europe, Latin America and Asia.

The American under-30 billionaires are all self-made, mostly in technology, while the European and Latin American young billionaires mostly inherited their fortunes, a contrast our top billionaire countries coverage frames.

The US and Germany lead: the United States has about eight young billionaires, all self-made, followed by Germany with six and Brazil with five, mostly heirs.

Beyond the leaders, young billionaires come from South Korea, India, Italy, Norway and Sweden, reflecting where great family fortunes have been passed to the next generation and where new self-made fortunes have been built. The spread of the youngest billionaires across a dozen countries, from the United States and Germany to Brazil, South Korea and India, reflects the global reach of both the technology boom and the great family dynasties.

Young Billionaires by Gender

Most of the youngest billionaires are men. Of the 35 under-30 billionaires in 2026, about 25 are men and about 10 are women, a gender gap that mirrors, though slightly narrows, the wider imbalance among billionaires as a whole. The gender balance among the youngest billionaires, while still heavily male, is slightly less lopsided than among billionaires as a whole, a hint that the next generation of great wealth may be a little more evenly shared. Of the 35 under-30 billionaires, about 25 are men and about 10 are women, so women make up around 29 percent of the youngest billionaires, a higher share than the 14 percent among billionaires as a whole.

The women among the youngest billionaires include heirs such as Amelie Voigt Trejes and Kim Jung-youn and the self-made Luana Lopes Lara, showing that young women reach the billionaire ranks through both inheritance and their own businesses, a pattern our leading billionaires coverage frames.

Mostly men: about 25 of the 35 under-30 billionaires are men and about 10 are women, a slightly narrower gender gap than among billionaires as a whole.

The slightly higher share of women among the youngest billionaires than among billionaires as a whole hints at a gradual narrowing of the gender gap, as more young women inherit or build great fortunes. The slightly higher share of women among the youngest billionaires than among the billionaire population as a whole, though still small, offers a tentative sign that the gender gap in great wealth may narrow in the generations to come.

The Ages of the Under-30 Billionaires

The under-30 billionaires span the ages of 20 to 29. The youngest, Amelie Voigt Trejes and Johannes von Baumbach, are 20, while the largest single group are the 22-year-olds, including the three self-made founders of Mercor. The spread of ages among the under-30 billionaires, from 20 to 29, reflects the different ways great wealth arrives young, from the moment of inheritance to the sudden surge in value of a young technology company. The under-30 billionaires range in age from 20 to 29, with the youngest, Amelie Voigt Trejes and Johannes von Baumbach, at 20, and the largest single group, including the three Mercor founders, at 22.

The spread of ages reflects the different routes to becoming a billionaire young, with heirs often becoming billionaires the moment they inherit and self-made founders reaching the mark as their startups soar in value, a pattern our largest asset managers coverage frames.

From 20 to 29: the under-30 billionaires range in age from 20 to 29, with the largest single group, including the three Mercor founders, at 22.

With billionaires as young as 20, the under-30 group is a reminder that great wealth can come very early, whether through inheritance or through the soaring valuations of a young technology startup. The concentration of the youngest billionaires in their early twenties, with several at just 20 and a large group at 22, underlines how the combination of inheritance and the technology boom is creating billionaires at ever younger ages.

How the Group Changed Since 2025

The under-30 group has grown but become less wealthy. The number of under-30 billionaires rose to a record 35 in 2026 from 30 in 2025, but their combined wealth fell to about 92 billion dollars from about 152 billion, as several richer members aged past 30. The way the under-30 group grew in number but shrank in combined wealth captures the churn at the very top of young wealth, as the richest members age out and a larger but less wealthy cohort takes their place. The number of under-30 billionaires rose from 30 in 2025 to a record 35 in 2026, even as their combined wealth fell from about 152 billion dollars to about 92 billion, as several richer members aged past 30.

The fall in combined wealth reflects the way the wealthiest young billionaires of last year, then in their early thirties, aged out of the under-30 group, leaving a larger but less wealthy cohort, a shift our crypto market coverage frames.

A shifting group: the number of under-30 billionaires rose in North America and Latin America from 2025 to 2026, while it edged down in Europe.

The growth in the number of under-30 billionaires, even as their combined wealth fell, reflects the rising number of young people reaching the billion-dollar mark, driven by both inheritance and the artificial-intelligence boom. The record number of under-30 billionaires, even amid a fall in their combined wealth, points to a long-term trend of great wealth reaching younger people, driven by both family inheritance and the soaring valuations of young startups. The long-term trend toward younger billionaires, driven by both inheritance and the technology boom, looks set to continue, even if the combined wealth of any single year cohort rises and falls with the markets.

The Youngest Billionaires in Numbers

A few numbers capture the picture. The youngest billionaire is Amelie Voigt Trejes at 20, there are a record 35 billionaires under 30, worth about 92 billion dollars between them, and a record 12 are self-made. These figures together map the youngest billionaires of 2026, a group still dominated by heirs but with a record number of self-made founders, above all in artificial intelligence, rising fast through the ranks. The overall picture is of a young billionaire class in transition, still led by heirs but with a rising tide of self-made founders, above all in artificial intelligence, reshaping the ranks of the very youngest rich.

The figures matter because the youngest billionaires reveal how great wealth is created and passed on, increasingly through technology as well as inheritance, a picture our euro to dollar exchange rate coverage sets in the global context.

Together these figures show a young billionaire class still dominated by heirs to great family fortunes, but with a record number of self-made founders, above all in artificial intelligence, rising fast.

The Youngest Billionaires: The Big Picture

Taken together, the youngest billionaires of 2026 map how great wealth reaches the young, through inheritance and, increasingly, through the artificial-intelligence boom, a story our gold as an investment coverage sets against other assets.

Whether more young people build their own fortunes will depend on the technology cycle, but the number of young billionaires has never been higher, alongside the markets in our hedge fund assets and federal funds rate overviews.
