Wealth rating firm Forbes states that most billionaires worldwide fall within the age range of 50 to 79. However, 12% of billionaires are younger than this range, achieving billionaire status by the age of 30.
According to Forbes, 21 individuals made the list of young billionaires in 2025, with 15 of them hailing from Europe.
In this year’s ranking, all but two of these young billionaires inherited their wealth.
The world’s youngest billionaire, Johannes von Baumbach (age 19), is the heir to Germany’s Boehringer Ingelheim, the world’s largest privately owned pharmaceutical company.
Here are the 21 youngest members of the World’s Billionaires list, all aged 30 and under, ranked from youngest to oldest according to Forbes’ 2025 billionaire list.
1. 19-year-old German Johannes von Baumbach with a net worth of $5.4 billion
Johannes is the youngest heir to the German pharmaceutical company Boehringer Ingelheim. The family is notoriously publicity-shy, and it’s unknown whether he or his three siblings have any role at the company.
The drugmaker has been led by a family member—Johannes’s uncle, Hubertus von Baumbach—since 2015. Johannes skis competitively in Austria.
2. 20-year-old Brazilian Lívia Voigt de Assis with a net worth of $1.2 billion with the source of wealth from Industrial machinery
Voigt is the youngest billionaire heir of WEG cofounder Werner Ricardo Voigt and owns a 3.1% stake in the company, like her sister. She is currently studying psychology at university.
After Forbes named her the world’s youngest billionaire last year, she shared on social media that she wished to avoid attention and would keep a low profile online.
3. 20-year-old Italian Clemente Del Vecchio, who has a net worth of $6.6 billion
Like his siblings, he owes his wealth to his 12.5% ownership of the holding company Delfin, which has a stake in EssilorLuxottica, the eyeglass company behind shade offerers like Arnette, Ray-Ban and Persol.
He has no role at EssilorLuxottica. He and his brother Luca (above) are the two children his late father had with the company’s former head of investor relations, Sabina Grossi.

5. 22-year-old German Kevin David Lehmann with a net worth of $3.6 billion with a source of wealth from drugstores
Lehmann inherited his fortune after his father quietly passed him a 50% stake in dm-drogerie markt, Germany’s leading drugstore chain, in 2017, when Lehmann was only 14. His dad first invested in the brand in 1974, shortly after it was founded in 1973; it’s since grown to own some 4,120 stores across Europe. Neither father nor son is involved with the company’s operations.

Dassault’s great-grandfather was a Holocaust survivor who invented a propeller used by the French Air Service in World War I and founded the company that would go on to become the aerospace giant Dassault Aviation. Remi owns an estimated 4.1% stake in that business, which he inherited upon his father’s death in 2021, as well as an estimated 2.5% stake in the software firm Dassault Systèmes.

9. 23-year-old Italian Luca Del Vecchio with a net worth of $6.6 billion
He and his brother and half-brother are the richest of the 30-and-unders, thanks to their minority stakes in the eyeglasses behemoth EssilorLuxottica. Their family holding entity Delfin also owns stakes in a variety of other companies based in Italy and France, including the bank UniCredit and the insurer Generali. He is not operationally involved with EssilorLuxottica or Delfin.
10. Maxim Tebar of Germany, with a net worth of $1.1 billion, is next on the list
The 24-year-old owes his fortune to a stake in Stihl, one of the world’s leading manufacturers of chainsaws and other handheld power equipment. The company was founded in 1926 by Andreas Stihl, who built the first two-person electric chainsaw. Now, it’s grown to have a presence in over 160 countries, though it remains entirely family-owned.
11. Katharina von Baumbach from Germany with a net worth of $5.4 billion

12. 26-year-old Zahan Mistry from Ireland with a net worth of $4 billion
Mistry’s father’s death left him and his brother (Firoz) with 4.6% stakes in Tata Sons. Now he and Firoz are helping to refinance the debts of the construction company Shapoorji Pallonji Group, in which they inherited 25% ownership.
In March, they secured $3.3 billion in credit for the SP Group from a slate of five private funds, including Ares Management Corp and Davidson Kempner Capital Management.
13. 27 year old German Maximilian von Baumbach is next with a net worth of $5.4 billion
While its heirs rank among the world’s youngest billionaires, the German drugmaker Boehringer Ingelheim is rather ancient—it was founded in 1885, and its entrepreneurial roots stretch back even further, to 1817. The company is behind four of the 30-and-under fortunes on this list; Maximilian is the oldest among them.
14. 27-year-old Brazilian Dora Voigt de Assis with a net worth of $1.2 billion
She and her sister own 3.1% of the Brazilian electrical motor producer WEG, which their late grandfather, Werner Ricardo Voigt, cofounded in 1961. The siblings have no roles at the company, which produces more than 21 million electric motors every year and exports them to more than 135 countries.
15. 28 year old American Alexandr Wang with a net worth of $2 billion
Wang is the world’s youngest self-made billionaire thanks to his artificial intelligence unicorn Scale AI, which raised $1 billion at a $13.8 billion valuation in May. Forbes estimates that he has a 14% stake in the company, which labels the data used to train the AI for large language models (including ChatGPT) and self-driving cars. He cofounded Scale, which now counts Microsoft, General Motors and Meta among its customers, with Lucy Guo in 2016, after dropping out of MIT following his freshman year.
16. 28-year-old Firoz Mistry from Ireland
He and his brother inherited 4.6% stakes in the $165 billion (revenue) Mumbai-based multinational conglomerate, Tata Sons, after their father died in a car accident in 2022.

17. 28-year-old Alexandra Andresen from Norway with a net worth of $1.9 billion
Andresen sits with her sister on the board of the investment company Ferd, which is based in the Oslo suburb of Bærum, and also owns a 42% stake.

She’s still heavily involved with horses and both owns and runs the Oslo horse-breeding stable Andresen Dressage.
18. 29-year-old Italian Leonardo Maria Del Vecchio with a net worth of $6.6 billion.
After his father’s death in 2022, Del Vecchio—and each of his six half-siblings and his mother—inherited a 12.5% stake in the family holding company that owns nearly a third of EssilorLuxottica, the world’s largest eyeglasses business. Del Vecchio is EssilorLuxottica’s chief strategy officer as well as the president of the iconic brand Ray-Ban.
19. 29-year-old Ed Craven from Australia with a net worth of $2.8 billion
Craven and Bijan Tehrani cofounded the online casino Stake.com, which managed to generate $4.7 billion last year even though crypto gambling is generally unavailable in the UK, U.S. and parts of Europe. Stake’s popularity has blown up since the pandemic, thanks in part to livestreamers filming themselves gambling on it. Now, the company says it’s involved in some 2% to 4% of all Bitcoin transactions.
20. 29-year-old Katharina Andresen from Norway with a net worth of $2 billion
Andresen’s fortune originally stems from the 150-year-old cigarette empire her father sold in 2005. After the sale, the family refocused on its investment firm, Ferd, which has portfolios in real estate, finance and a variety of private Nordic companies. Like her sister, she owns a 42% stake in Ferd and sits on the board. She’s also a strong supporter of LGBTQ+ rights and is an advisor for Oslo Pride.
21. 30-year-old German Sophie Luise Fielmann with a net worth of $2.8 billion
Sophie and her older brother Marc inherited much of their late father Günther Fielmann’s fortune when he died last year. Fielmann founded Fielmann AG in 1972 with the goal of bringing affordable eyeglasses to Germany. Marc co-led the company with his dad starting in 2018 and fully took over the following year. Sophie owns a third of its stock but has no role at the firm.
