20 Youngest Billionaires in the World 2025

The world’s billionaire club is getting some notably younger members. In fact, out of the over 2,500 billionaires globally, only a rare few – just 21 individuals – are under the age of 30. These ultra-wealthy youth stand in stark contrast to the typical billionaire (average age mid-60s) and owe their fortunes largely to family legacies. For the first time in over a decade, every billionaire under 30 has inherited their wealth – a testament to how major “wealth transfer” events (like the passing of visionary founders and patriarchs) are minting young heirs. While a handful of entrepreneurs in their 30s made their own billions (think tech founders in their mid-30s), the sub-30 billionaires overwhelmingly come from dynastic fortunes rather than startups.In this ranked list, we count down the 20 youngest billionaires in the world as of 2025. Lets dive in!

1. Johannes von Baumbach, 19

• Estimated Net Worth (2025): $5.4 billion

Johannes von Baumbach is just 19 years old, making him the world’s youngest billionaire. He is an heir to Germany’s Boehringer Ingelheim pharmaceutical fortune – the largest privately-owned pharma company globally, founded by his family in 1885. Johannes and his three older siblings each inherited roughly a $5.4 billion stake in the firm, following a generational wealth transfer. The von Baumbach family is famously private, and Johannes holds no public role at Boehringer Ingelheim. Still a teenager, he keeps a low profile as his company’s medicines (for diabetes, respiratory diseases, etc.) reach patients worldwide.

2. Lívia Voigt de Assis, 20

• Estimated Net Worth (2025): $1.2 billion

At 20 years old, Brazil’s Lívia Voigt de Assis is the youngest female billionaire in the world. She is one of the largest individual shareholders of WEG, Latin America’s biggest industrial motor manufacturer, which her late grandfather Werner Voigt co-founded. Lívia inherited about a 3.1% stake in the publicly traded WEG, and despite her wealth, she holds no executive role or board seat at the company. In fact, she’s currently a university student studying psychology, and has expressed a desire to avoid the spotlight and maintain her privacy. Her family’s company, meanwhile, continues to thrive with factories in over 10 countries and billions in revenue each year.

3. Clemente Del Vecchio, 20

• Estimated Net Worth (2025): ~$6 billion

Clemente Del Vecchio, age 20, is one of the heirs of the Luxottica eyewear empire. He is one of six children of the late Leonardo Del Vecchio, founder of the Ray-Ban and Oakley-making eyewear giant (now part of EssilorLuxottica). After his father’s passing in 2022, Clemente inherited a 12.5% stake in Delfin, the family’s Luxembourg-based holding company. Through Delfin, Clemente’s wealth ties to major holdings in EssilorLuxottica, insurer Generali, banks like Mediobanca and UniCredit, among others. Despite inheriting a fortune (around $6 billion at age 20), Clemente has shown a keen interest in science and technology and has plans to attend college to pursue a career independent of the family business. For now, he remains a beneficiary of the booming eyewear and finance investments his father built.

4. Kim Jung-youn, 21

• Estimated Net Worth (2025): $1.3 billion

Kim Jung-youn, 21, is a South Korean billionaire thanks to her stake in Nexon, one of Asia’s online gaming powerhouses. She and her older sister (see #6 below) inherited sizable stakes (through holding company NXC) in Nexon after their father, Kim Jung-ju, the founder of Nexon, passed away in 2022. Kim Jung-youn’s roughly 9% share of Nexon is the source of her $1.3 billion net worth. Despite being a major shareholder of a global gaming firm (maker of MapleStory and many other popular games), she has no active role in the business and stays out of the public eye. In fact, both Kim sisters made headlines as some of the youngest heirs in tech, while Nexon itself continues to thrive across 190 countries with dozens of live game titles.

5. Kevin David Lehmann, 22

• Estimated Net Worth (2025): $3.6 billion

Kevin David Lehmann, age 22, is a German billionaire who inherited a 50% stake in dm-drogerie markt (dm), Germany’s largest drugstore chain. Kevin’s father, Guenther Lehmann, had quietly acquired a stake in dm back in the 1970s when it was a single store, and helped it grow into a retail giant with over 4,000 stores across Europe. In 2017, when Kevin was just 14, his father transferred the 50% ownership to him (held in trust until Kevin came of age). Since turning 18 and formally acquiring the stake, Kevin’s net worth has climbed to about $3.6 billion. Notably, neither Kevin nor his father have any operational involvement in dm’s day-to-day business, and the family is known for keeping a very low profile. Kevin’s fortune grows passively as dm continues to post billions in annual revenue.

6. Kim Jung-min, 23

• Estimated Net Worth (2025): $1.3 billion

At 23, Kim Jung-min is the elder sister of Kim Jung-youn (#4) and likewise an heiress to the Nexon online gaming fortune. She and her sister each hold roughly one-third ownership of NXC, the holding company that controls Nexon, after inheriting their late father’s shares. Kim Jung-min’s net worth is about $1.3 billion (very similar to her younger sister’s). Like her sister, Jung-min maintains a private lifestyle and is not involved in Nexon’s operations. The two siblings became notable in 2022 as the world’s youngest billionaire sisters when their father, Nexon’s founder, died unexpectedly. Today, they quietly remain significant stakeholders in the gaming giant, while opting out of any public-facing corporate roles.

7. Franz von Baumbach, 23

• Estimated Net Worth (2025): $5.4 billion

Franz von Baumbach, age 23, is one of Johannes von Baumbach’s older brothers and a fellow heir to the Boehringer Ingelheim pharmaceutical fortune. Franz and his siblings (see #1, #12, #14) each received an estimated multibillion-dollar stake in Boehringer Ingelheim, making Franz worth roughly $5.4 billion in his early twenties. His family’s company is among the world’s top pharma firms, but Franz – like his siblings – has no public or managerial role in it. The von Baumbach heirs are known for their secrecy; virtually nothing personal is known about Franz, and he stays entirely out of the limelight. His wealth represents the continuation of a 130-year-old family business, now passed down to a new generation after the previous leaders stepped aside.

8. Luca Del Vecchio, 23

• Estimated Net Worth (2025): $6.6 billion

Luca Del Vecchio, 23, is another heir of the Del Vecchio eyewear fortune – he’s a half-brother to Clemente (#3) and one of the late Leonardo Del Vecchio’s six children. Like his brother, Luca inherited 12.5% of Delfin, the family holding company that controls EssilorLuxottica (the Ray-Ban, Oakley maker) as well as sizable stakes in financial firms and real estate holdings. Luca’s net worth is approximately $6.6 billion, reflecting the value of those holdings. Unlike Clemente, Luca does take an active role in the family business – he serves as Chief Strategy Officer at Delfin’s operations in Milan. In fact, among the Del Vecchio heirs, Luca is noted for being engaged in corporate affairs, helping steer the legacy companies, while his younger brother Clemente focuses on personal interests like science and education.

9. Rémi Dassault, 23

• Estimated Net Worth (2025): $2.8 billion

Rémi Dassault, 23, is an heir of France’s prominent Dassault industrial dynasty. He inherited his wealth after his father, Olivier Dassault (a businessman and politician), tragically died in a helicopter crash in 2021. Rémi’s fortune – about $2.8 billion – comes from the family’s conglomerate, which includes stakes of roughly 2.5% in software firm Dassault Systèmes and 4% in Dassault Aviation. His great-grandfather, Marcel Dassault, founded Dassault Aviation (known for Mirage and Rafale fighter jets and Falcon business jets) in the early 20th century. The Dassaults also own Le Figaro and vineyards among other assets. Rémi, still only in his early twenties, has not yet taken on a public leadership role in the empire. He represents the fourth generation of a family that remains deeply influential in French aerospace, defense, and media.

10. Maxim “Max” Tebar, 24

• Estimated Net Worth (2025): $1.1 billion

Maxim Tebar, 24, is a fourth-generation heir to the Stihl chainsaw fortune in Germany. His mother, Karen Tebar, is a member of the Stihl family (she serves as vice-chair of the company’s advisory board). Maxim’s estimated net worth of $1.1 billion comes from his stake in Andreas Stihl AG, the world’s leading manufacturer of chainsaws and power tools. The company, founded in 1926 by Maxim’s great-grandfather, remains family-owned, with annual sales in the billions. Maxim, at 24, has no public operational role in the business yet. However, his inheritance secures his position among the world’s youngest billionaires, with a fortune rooted in a nearly century-old industrial legacy.

11. Zahan Mistry, 25

• Estimated Net Worth (2025): $4.9 billion

At 25, Zahan Mistry is one of the two young Mistry brothers who inherited a substantial stake in India’s famed Tata conglomerate. Zahan and his elder brother Firoz (#15) are sons of the late Cyrus Mistry, former chairman of Tata Sons. Each brother received an 18.4% family stake in Tata Sons (split with their uncle), which translates to roughly 4.6% ownership for each brother in the $150 billion-revenue Tata Group holding company. Thanks to Tata Sons – which oversees giants like Tata Motors and Tata Consultancy Services – Zahan is worth an estimated $4.9 billion. In addition, the Mistrys own half of the Shapoorji Pallonji Group, a large construction and engineering firm, and Zahan himself holds a 25% stake in that family enterprise. Unlike many young heirs, Zahan has stepped up in business: he is actively involved in the family’s construction empire and has helped restructure debt-laden parts of the group after his father’s passing. He and his brother, though Irish citizens, reside in Mumbai to oversee their Indian businesses.

12. Katharina von Baumbach, 25

• Estimated Net Worth (2025): $5.4 billion

Katharina von Baumbach, 25, is the only sister among the four von Baumbach siblings who inherited stakes in Boehringer Ingelheim. As a member of this ultra-rich German pharma family, Katharina holds an equal share of the fortune alongside her brothers Johannes (#1), Franz (#7), and Maximilian (#14). Her net worth is roughly $5.4 billion, reflecting her portion of ownership in Boehringer Ingelheim. Katharina is now Germany’s youngest woman billionaire, yet she and her family remain very private. She does not serve in any executive capacity at Boehringer, and little is publicly known about her personal endeavors.

13. Dora Voigt de Assis, 26

• Estimated Net Worth (2025): $1.1 billion

Dora Voigt de Assis, 26, is the elder sister of Lívia Voigt (#2) and a fellow heiress of Brazil’s WEG industrial fortune. Dora and Lívia are the granddaughters of WEG’s co-founder Werner Voigt, and each sister owns about 3.1% of WEG’s shares. Dora’s stake makes her worth approximately $1.1 billion. Like her younger sister, Dora has no active role at WEG – she isn’t on the board or management team. In fact, Dora pursued her own interests: she graduated with an architecture degree in 2020. WEG, which manufactures electrical motors and equipment and exports to 135+ countries, continues to thrive as a public company. Dora, for her part, stays out of the company’s operations, enjoying the benefits of dividends and growth while focusing on her personal life.

14. Maximilian von Baumbach, 27

• Estimated Net Worth (2025): $5.4 billion

Maximilian von Baumbach, 27, is the eldest of the von Baumbach siblings and another heir to the Boehringer Ingelheim fortune. Maximilian inherited the same roughly $5.4 billion stake in the family’s pharma company as his younger brothers and sister. He represents the fourth sibling in this list, underscoring how the Boehringer/von Baumbach family transfer created multiple young billionaires at once. At 27, Maximilian keeps a very low public profile, much like his siblings – none of them are known to have operational roles at Boehringer Ingelheim.

15. Firoz Mistry, 27

• Estimated Net Worth (2025): $4.9 billion

Firoz Mistry, 27, is the elder of the two billionaire Mistry brothers (see Zahan at #11) who inherited big stakes in India’s Tata Sons. Firoz and Zahan each hold about 4.6% of Tata Sons, split from their family’s 18.4% ownership. That stake, along with a 25% holding in the Shapoorji Pallonji Group, gives Firoz a net worth around $4.9 billion. Educated at the University of Warwick, Firoz has been described as having sharp business acumen and “strategic foresight.” He and his brother have taken on active roles in the indebted Shapoorji Pallonji Group, working on reorganizing the company after their father’s untimely death. Firoz’s fortune is rooted in an old-line business empire, but his approach combines inheritance with hands-on leadership.

16. Alexandra Andresen, 28

• Estimated Net Worth (2025): $1.6 billion

Alexandra Andresen, 28, is a Norwegian heiress known for once being the world’s youngest billionaire. She and her older sister Katharina (#18) each own 42% of Ferd AS, the Andresen family’s centuries-old investment company. Ferd, which their father Johan continues to run, invests in everything from Nordic private companies to hedge funds, and was built on the family’s historic tobacco business sale proceeds. Alexandra’s stake makes her worth about $1.6 billion. Now in her late 20s, she has pursued her passion for equestrian sports – she was a three-time Norwegian junior dressage champion. While she now serves on Ferd’s board, much of her focus has been outside the boardroom: she runs an elite horse breeding and dressage training stable near Oslo.

17. Leonardo Maria Del Vecchio, 28

• Estimated Net Worth (2025): $4.7 billion

Leonardo Maria Del Vecchio, 28, is another scion of the Del Vecchio eyewear dynasty. He inherited 12.5% of the Delfin holding company when his father – once Europe’s richest man – died in 2022. Leonardo Maria’s $4.7 billion fortune stems from the family’s shares in EssilorLuxottica. Notably, Leonardo Maria plays a significant role in the business: he serves as Director of Strategy at EssilorLuxottica. Along with his mother and six half-siblings, he inherited the stake in Delfin, which owns a big chunk of EssilorLuxottica and other investments. His active involvement contrasts with some of his younger half-siblings, ensuring the Del Vecchio legacy remains strong.

18. Katharina Andresen, 29

• Estimated Net Worth (2025): $1.7 billion

Katharina Andresen, 29, is the elder Andresen sister and part-owner of the Ferd investment group alongside Alexandra (#16). Her fortune stands around $1.7 billion, reflecting her 42% share of the family investments in real estate, energy, and finance across Scandinavia. Katharina has been involved with Ferd by gradually learning the ropes: she spent years as a board observer and officially joined the company’s board of directors in 2022. With Norway’s business community watching, Katharina is poised to help steer Ferd’s future while balancing the duty of inherited wealth with a desire for a normal life.

19. Sophie Luise Fielmann, 29

• Estimated Net Worth (2025): $2.7 billion

Sophie Luise Fielmann, 29, became a billionaire in 2024 after her father, Günther Fielmann, passed away. She inherited a significant stake in Fielmann AG, the European eyewear chain known for affordable glasses. Sophie’s roughly one-third share gives her a fortune of about $2.7 billion. Unlike her brother Marc (the company’s CEO), Sophie does not take an active role in the business, maintaining a low profile while benefiting from the family’s pioneering retail legacy.

20. Wang Zelong, 28

• Estimated Net Worth (2025): ~$1.4 billion

Wang Zelong, 28, is often cited as the youngest billionaire in Asia. He inherited a fortune in the form of shares of CNNC Hua Yuan Titanium Dioxide Co., a Chinese chemicals company. Those shares – worth roughly $1.3–1.5 billion – were transferred to Wang when he was in his early 20s. Little is publicly known about him personally; he keeps a very low profile and is not a company founder or executive, but rather an inheritor of a large equity stake.
