Roughly half of the global population is 30 or younger, yet only 21 individuals among them have reached billionaire status. Amassing such wealth typically spans decades, if not a lifetime. The data underscores this: nearly three-quarters of the world’s billionaires fall between ages 50 and 79, with just 12% under 50. Rarer still are those who achieve this milestone by 30, and in 2025, just 21 young tycoons make the cut on the World’s Billionaires list.

Remarkably, all but two inherited their fortunes. Take Johannes von Baumbach, the world’s youngest billionaire at 19, who owes his $5.4 billion net worth to a stake in Germany’s Boehringer Ingelheim, the largest privately-owned pharmaceutical firm. Alongside his three siblings—aged 23, 25, and 27—he exemplifies the trend of generational wealth transfer.

Europe dominates this youthful elite, claiming 15 of the 21 spots. Germany leads with the four von Baumbachs, plus heirs like Sophie Luise Fielmann (30; eyeglasses), Kevin David Lehmann (22; drugstores), and Maxim Tebar (23; chainsaws). Italy follows, with the three Del Vecchio brothers riding a 40% fortune surge to $6.6 billion each, fueled by EssilorLuxottica’s stellar 2024 stock performance.

Beyond Europe, sibling pairs from South Korea and Brazil inherited riches from online gaming and industrial machinery, respectively. The exceptions to the inheritance rule are two self-made standouts: Australia’s Ed Craven (29), co-founder of Stake.com, the world’s top crypto-backed casino with $4.7 billion in 2024 revenue, and the U.S.’s Alexandr Wang (28), whose AI venture Scale AI hit a $13.8 billion valuation in May 2024, marking his second billionaire stint.
