•Johannes von Baumbach
As of early 2026, the list of the world’s youngest billionaires is a fascinating mix of heirs to massive family industries and a new wave of “self-made” tech founders who have struck it rich in the artificial intelligence boom.
Here are the top 10 youngest billionaires in the world:
1. Amelie Voigt Trejes (20 years old)
Amelie is currently the youngest billionaire on the planet. Her wealth comes from a significant stake in WEG, a Brazilian company that is one of the largest manufacturers of electric motors in the world. She is the granddaughter of the company’s co-founder and, while she owns a massive piece of the business worth about $1.1 billion, she is currently a university student and doesn’t run the company’s daily operations.
2. Johannes von Baumbach (20 years old)
Just a few weeks older than Amelie, Johannes is a German heir to the Boehringer Ingelheim fortune. This is one of the world’s largest private pharmaceutical companies. Because the company is so massive and successful, his inherited stake gives him a net worth of roughly $6.4 billion, making him the wealthiest person in this age group.
3. Lívia Voigt de Assis (21 years old)
Lívia is Amelie’s older sister. Like her sibling, her wealth (about $1.2 billion) comes from the family’s shares in the Brazilian industrial giant WEG. She is also a student and lives a relatively private life despite her ten-digit bank account.
4. Clemente Del Vecchio (21 years old)
Clemente is one of the heirs to the EssilorLuxottica empire—the company behind almost every major glasses brand you know, including Ray-Ban and Oakley. After his father, Leonardo Del Vecchio, passed away in 2022, Clemente inherited a stake in the family’s holding company, which is currently valued at approximately $5.7 billion.
5. Kim Jung-youn (22 years old)
Based in South Korea, Jung-youn inherited a large stake in NXC, which is the parent company of the massive video game publisher Nexon (famous for games like MapleStory). Following the death of her father, the company’s founder, she became a billionaire with a net worth of around $1.5 billion.
6. Surya Midha (22 years old)
Surya is a standout on this list because he is “self-made.” He is the co-founder of Mercor, an AI-driven hiring platform that uses algorithms to match software engineers with jobs. Because his company’s valuation skyrocketed to $10 billion recently, his personal share is worth about $2.2 billion. He is currently the youngest self-made billionaire in the world.
7. Brendan Foody (22 years old)
Brendan is one of Surya Midha’s co-founders at Mercor. Like Surya, his wealth comes from his ownership in the AI startup. He shares a similar net worth of $2.2 billion. The success of these young founders is often cited as a prime example of how quickly AI is creating new wealth.
8. Adarsh Hiremath (22 years old)
The third co-founder of Mercor, Adarsh rounds out the trio of young AI entrepreneurs. He also holds a net worth of $2.2 billion. These three friends made history this year by becoming billionaires at an age younger than Mark Zuckerberg was when he first joined the list.
9. Kevin David Lehmann (23 years old)
Kevin is a German billionaire who owns 50% of dm (drogerie markt), which is Germany’s leading drugstore chain. His father gave him his stake in the company when he was just 14, but it remained under a trusteeship until he turned 18. Today, his stake is worth about $4.6 billion.
10. Pedro Voigt Trejes (23 years old)
Pedro is the older brother of Amelie and Lívia (the top and third spots on this list). Like his sisters, he inherited his wealth through the Brazilian industrial company WEG. His net worth is approximately $1.0 billion, keeping the Voigt family firmly planted as one of the most successful young dynasties in the world.
