Who is the youngest billionaire and what is his age?

The Rise of Young Wealth: Inside the World’s Youngest Billionaires

At just 20 years old, Johannes von Baumbach stands out as one of the world's most formidable young fortunes. Hailing from Germany, the young heir boasts an estimated net worth of $6.6 billion, placing him firmly at the summit of youthful wealth.

Unlike tech entrepreneurs who build empires from Silicon Valley garages, Johannes inherited his fortune through the pharmaceutical giant Boehringer Ingelheim. Founded in 1885, the privately-held firm remains a major global player, securing vast wealth across generations for the family dynasty.

He isn't alone in this exclusive tier of early-twenties billionaires. Brazil's Livia Voigt, aged 21, holds a fortune of $1.4 billion tied to industrial equipment manufacturer WEG. Meanwhile, Italy’s Clemente Del Vecchio, also 21, commands $6.8 billion through his family stake in eyewear giant EssilorLuxottica. Further east, South Korea’s Kim Jung-youn, 22, holds around $1.7 billion from the gaming conglomerate NXC.

What sets these ultra-wealthy individuals apart is not just their extraordinary age, but how discreetly they manage their daily lives. Most maintain low public profiles while professional management teams run daily corporate operations, leaving these young heirs to navigate university, personal life, and the unique weight of astronomical family legacies.
