Roughly half the people on the planet are aged 30 or younger. Just 21 of them are billionaires.
Building a fortune usually takes years—even a lifetime. The numbers speak for themselves: Nearly three-quarters of the world’s billionaires are between the ages of 50 and 79. Just 12% are under 50. The rarest of all are those who manage to achieve billionaire status by the age of 30; this year there are just 21 of those flush youngsters on the Forbes list.
Unsurprisingly, all but two of them inherited their wealth. That goes for the world’s youngest billionaire, Johannes von Baumbach (age 19), heir to Germany’s Boehringer Ingelheim, the world’s largest privately-owned pharmaceutical company. He and three siblings—ages 23, 25 and 27—are each worth an estimated $5.4 billion thanks to a stake in the drugmaker.
The vast majority of the billionaire youths—15 of them—are from Europe. Germany has the most on the continent, with the four von Baumbachs as well as the heirs Sophie Luise Fielmann (age 30; eyeglasses), Kevin David Lehmann (22; drugstores) and Maxim Tebar (23; chainsaws). After that comes Italy, where three Del Vecchio brothers inherited part of the eyeglasses empire EssilorLuxottica. Their fortunes are all up 40%, to $6.6 billion, this year thanks to the company’s soaring stock price after strong earnings growth in 2024.
Outside Europe, there are two sibling pairs in South Korea and Brazil who respectively inherited fortunes in online gaming and industrial machinery.
Then there are the only two self-made billionaires on the list. One is Australia’s Ed Craven (29), who cofounded Stake.com, thought to be the world’s biggest crypto-backed online casino, with $4.7 billion in revenue last year. The other is the United States’ Alexandr Wang (28), who cofounded the AI data annotation unicorn Scale AI and who recently became a billionaire for the second time. Back in 2021, a $7.3 billion valuation of the company gave Wang his first go at a three-comma fortune, but he dropped off the Forbes list in 2023 amid a swath of plummeting private tech valuations. Now, thanks to a May funding round that valued Scale AI at $13.8 billion, the company—and Wang—are back.
Here are the 21 youngest members of the World’s Billionaires list, all of whom are 30 and under, ranked from oldest to youngest.
