Most billionaires are much older, with nearly 75% between the ages of 50 and 79.
In fact, only 21 people under the age of 30 made it onto the 2025 Forbes Billionaires List.
These young billionaires are rare outliers, and almost all of them inherited their wealth rather than earning it from scratch.
Only two of the under-30 billionaires are truly self-made entrepreneurs.
Below, we profile the ten youngest billionaires in the world, highlighting their ages, origins of wealth, and whether they built their fortunes or had them handed down by family.
1. Johannes von Baumbach (19)
At just 19 years old, Johannes is the world’s youngest billionaire.
He is an heir to Germany’s Boehringer Ingelheim, the world’s largest private pharmaceutical company.
Johannes and his three siblings (aged 23, 25, and 27) each inherited an estimated $5.4 billion stake in the family business.
None of them have active roles in the company, which is still run by their relatives.
In short, Johannes’s immense wealth comes from his family’s pharma empire rather than any venture of his own.
2. Clemente Del Vecchio (20)
Clemente is a 20-year-old billionaire from Italy who owes his fortune to his late father, Leonardo Del Vecchio.
Leonardo founded Luxottica, the eyewear giant behind brands like Ray-Ban and Oakley.
When his father passed in 2022, Clemente inherited a 12.5% stake in the family’s holding company (Delfin), which owns a large share of EssilorLuxottica.
This inheritance instantly made Clemente one of the world’s youngest billionaires.
Today, his net worth is roughly $6.1 billion at age 20, all built on his family’s eyewear empire.
3. Lívia Voigt de Assis (20)
Lívia Voigt, 20, is the world’s youngest female billionaire.
She is a Brazilian college student who became a billionaire due to her family’s stake in WEG, a major electric motor manufacturing company co-founded by her grandfather.
Lívia is one of the largest individual shareholders of WEG, giving her an estimated $1.1 billion net worth.
Despite her fortune, she’s focused on her education and holds no executive role in the business.
Lívia’s story illustrates how legacy wealth can catapult someone so young into billionaire status.
4. Kim Jung-youn (21)
Kim Jung-youn, age 21, became a billionaire after the death of her father, Kim Jung-ju.
Her father founded Nexon, a South Korean online gaming empire known for games like MapleStory.
In 2022, Kim Jung-youn and her sister inherited roughly a third of their family’s assets, including about a 15% stake each in Nexon’s holding company.
This inheritance gives Kim Jung-youn an estimated $1.3 billion fortune at 21.
Neither she nor her sister is involved in running the gaming business, and they keep a very low profile.
Kim’s wealth is a direct result of her family’s success in the video game industry.
5. Kevin David Lehmann (22)
Kevin Lehmann, 22, is a German billionaire who inherited a 50% stake in dm-drogerie markt, Germany’s largest drugstore chain.
His father, Guenther Lehmann, transferred ownership of the stake to Kevin, which was held in trust until Kevin turned 18.
Upon coming of age, Kevin became one of the world’s youngest billionaires overnight.
He is now worth about $3.4 billion, thanks to this massive inheritance.
Like many young heirs, Kevin stays out of the spotlight and isn’t actively involved in the day-to-day operations of the family business.
6. Luca Del Vecchio (23)
Luca, 23, is another heir of the late Leonardo Del Vecchio’s eyewear fortune.
He and his younger brother Clemente (profiled above) each inherited 12.5% of the family holding company, which controls a big stake in EssilorLuxottica.
This inheritance has made Luca worth roughly $6.1 billion at age 23.
He is one of six children of Leonardo Del Vecchio and, much like his siblings, benefits from the family’s global eyeglasses empire.
(His older half-brother Leonardo Maria Del Vecchio, 28, also became a billionaire from the same inheritance and even holds an executive role at the company.)
Luca’s wealth firmly comes from continuing his father’s legacy in the eyewear industry.
7. Franz von Baumbach (23)
Franz, 23, is the older brother of Johannes von Baumbach.
He is one of four siblings who collectively inherited the Boehringer Ingelheim pharma fortune in Germany.
Franz, like his younger brother, is worth about $5.4 billion based on his share in the privately held drug company.
The von Baumbach family is known for being very private, and Franz has no public role at Boehringer Ingelheim.
Essentially, Franz’s billionaire status is a product of family wealth, as he gained his stake in the pharmaceutical firm through inheritance.
8. Kim Jung-min (23)
Kim Jung-min, 23, is the elder sister of Kim Jung-youn and likewise a beneficiary of the Nexon online gaming fortune.
After their father’s passing, Jung-min also received around a 15% stake in the family’s holding company NXC, which owns part of Nexon.
This has given her an estimated net worth of about $1.3 billion in her early twenties.
Like her younger sister, Kim Jung-min remains outside the public eye and isn’t involved in running Nexon.
Her wealth underscores how the next generation of a tech empire can become billionaires purely through inheritance.
9. Rémi Dassault (24)
Rémi Dassault, 24, comes from one of France’s most prominent industrial families.
He is an heir to the Dassault Group, known for Dassault Aviation (which makes Mirage and Rafale fighter jets) and the software firm Dassault Systèmes.
Rémi’s family legacy in aerospace and technology has bestowed him a fortune of roughly $2.6 billion.
He represents the new generation of the Dassault dynasty.
While details about Rémi are scarce, he is part of a prestigious lineage (his grandfather was Serge Dassault), and his wealth is rooted in the thriving family business.
In his twenties, Rémi is already working to carry forward the family’s diversified empire.
10. Ed Craven (29)
Ed Craven is one of the few self-made billionaires on this list. At 29, he co-founded Stake.com, a wildly successful crypto-based online casino.
In just a few years, Stake.com grew to handle up to 4% of global Bitcoin transactions and generated billions in betting volume.
Ed’s innovative venture into cryptocurrency gambling has earned him an estimated $2.8 billion in net worth.
Unlike the others above, Ed built his fortune from the ground up instead of inheriting it.
In fact, Ed Craven and 28-year-old Alexandr Wang (co-founder of Scale AI) are the only two billionaires under 30 who made their own money rather than getting it from family.
Ed’s story stands out as a testament to youthful entrepreneurship, proving that not every young billionaire is born into wealth.
