The World's Youngest Billionaires 2025: 21 Under 30
Building a fortune usually takes years—even a lifetime. The numbers speak for themselves: Nearly three-quarters of the world's billionaires are between the ages of 50 and 79. Just 12% are under 50. The rarest of all are those who manage to achieve billionaire status by the age of 30; this year there are just 21 of those flush youngsters on the Forbes list.
Unsurprisingly, all but two of them inherited their wealth. That goes for the world's youngest billionaire, Johannes von Baumbach (age 19), heir to Germany's Boehringer Ingelheim, the world's largest privately-owned pharmaceutical company. He and three siblings—ages 23, 25 and 27—are each worth an estimated $5.4 billion thanks to a stake in the drugmaker.
The vast majority of the billionaire youths—15 of them—are from Europe. Germany has the most on the continent, with the four von Baumbachs as well as the heirs Sophie Luise Fielmann (age 30; eyeglasses), Kevin David Lehmann (22; drugstores) and Maxim Tebar (23; chainsaws). After that comes Italy, where three Del Vecchio brothers inherited part of the eyeglasses empire EssilorLuxottica. Their fortunes are all up 40%, to $6.6 billion, this year thanks to the company's soaring stock price after strong earnings growth in 2024.
Outside Europe, there are two sibling pairs in South Korea and Brazil who respectively inherited fortunes in online gaming and industrial machinery.
Then there are the only two self-made billionaires on the list. One is Australia's Ed Craven (29), who cofounded Stake.com, thought to be the world's biggest crypto-backed online casino, with $4.7 billion in revenue last year. The other is the United States' Alexandr Wang (28), who cofounded the AI data annotation unicorn Scale AI and who recently became a billionaire for the second time. Back in 2021, a $7.3 billion valuation of the company gave Wang his first go at a three-comma fortune, but he dropped off the Forbes list in 2023 amid a swath of plummeting private tech valuations. Now, thanks to a May funding round that valued Scale AI at $13.8 billion, the company—and Wang—are back.
Sophie and her older brother Marc inherited much of their late father Günther Fielmann's fortune when he died last year. Fielmann founded Fielmann AG in 1972 with the goal of bringing affordable eyeglasses to Germany. Marc co-led the company with his dad starting in 2018 and fully took over the following year. Sophie owns a third of its stock but has no role at the firm.
Andresen's fortune originally stems from the 150-year-old cigarette empire her father sold in 2005. After the sale, the family refocused on its investment firm Ferd, which has portfolios in real estate, finance and a variety of private Nordic companies. Like her sister (below), she owns a 42% stake in Ferd and sits on the board. She's also a strong supporter of LGBTQ+ rights and is an advisor for Oslo Pride.
Craven and Bijan Tehrani cofounded the online casino Stake.com, which managed to generate $4.7 billion last year even though crypto gambling is generally unavailable in the UK, U.S. and parts of Europe. Stake's popularity has blown up since the pandemic thanks in part to livestreamers filming themselves gambling on it. Now the company says it's involved in some 2% to 4% of all Bitcoin transactions.
After his father's death in 2022, Del Vecchio—and each of his six half-siblings and his mother—inherited a 12.5% stake in the family holding company that owns nearly a third of EssilorLuxottica, the world's largest eyeglasses business. Del Vecchio is EssilorLuxottica's chief strategy officer as well as the president of the iconic brand Ray-Ban.
Andresen sits with her sister (above) on the board of the investment company Ferd, which is based in the Oslo suburb of Bærum, and also owns a 42% stake. She is a three-time junior Norwegian champion in dressage horse riding but no longer competes due to spinal health problems. She's still heavily involved with horses and both owns and runs the Oslo horse-breeding stable Andresen Dressage.
He and his brother (below) inherited 4.6% stakes in the $165 billion (revenue) Mumbai-based multinational conglomerate Tata Sons after their father died in a car accident in 2022. The group, which owns 30 companies spanning everything from cars to jewelry, was founded in 1868 and currently has a presence across six continents and over 100 countries.
Wang is the world's youngest self-made billionaire thanks to his artificial intelligence unicorn Scale AI, which raised $1 billion at a $13.8 billion valuation in May. Forbes estimates that he has a 14% stake in the company, which labels the data used to train the AI for large language models (including ChatGPT) and self-driving cars. He cofounded Scale, which now counts Microsoft, General Motors and Meta among its customers, with Lucy Guo in 2016, after dropping out of MIT following his freshman year.
She and her sister (below) own 3.1% of the Brazilian electrical motor producer WEG, which their late grandfather Werner Ricardo Voigt cofounded in 1961. The siblings have no roles at the company, which produces more than 21 million electric motors every year and exports them to more than 135 countries.
While its heirs rank among the world's youngest billionaires, the German drugmaker Boehringer Ingelheim is rather ancient—it was founded in 1885, and its entrepreneurial roots stretch back even further, to 1817. The company is behind four of the 30-and-under fortunes on this list; Maximilian is the oldest among them. His siblings are below.
Mistry's father's death left him and his brother (Firoz, above) with 4.6% stakes in Tata Sons. Now he and Firoz are helping to refinance the debts of the construction company Shapoorji Pallonji Group, in which they inherited 25% ownership. In March, they secured $3.3 billion in credit for the SP Group from a slate of five private funds, including Ares Management Corp and Davidson Kempner Capital Management.
Katharina is the third-youngest inheritor of the German drugmaker Boehringer Ingelheim fortune. With three brothers, she's the only woman among its young heirs.
Tebar owes his fortune to a stake in Stihl, one of the world's leading manufacturers of chainsaws and other handheld power equipment. The company was founded in 1926 by Andreas Stihl, who built the first two-person electric chainsaw. Now it's grown to have a presence in over 160 countries, though it remains entirely family-owned.
Dassault's great-grandfather was a Holocaust survivor who invented a propeller used by the French Air Service in World War I, and founded the company that would go on to become the aerospace giant Dassault Aviation. Remi owns an estimated 4.1% stake in that business, which he inherited upon his father's death in 2021, as well as an estimated 2.5% stake in the software firm Dassault Systèmes.
He and his brother and half-brother (below and above) are the richest of the 30-and-unders, thanks to their minority stakes in the eyeglasses behemoth EssilorLuxottica. Their family holding entity Delfin also owns stakes in a variety of other companies based in Italy and France, including the bank UniCredit and the insurer Generali. He is not operationally involved with EssilorLuxottica or Delfin.
She and her sister (below) inherited approximately 9% stakes in Nexon, a South Korean-Japanese online gaming company, after the 2022 death of their father, company founder Kim Jung-ju. Nexon was a pioneer of the free-to-play gaming model and is also an industry leader of massively multiplayer online role-playing games, or MMORPGs.
Franz is the second-youngest heir to the Ingelheim-based German drugmaker Boehringer Ingelheim. Little is known about him or his siblings (above and below).
Lehmann inherited his fortune after his father quietly passed him a 50% stake in dm-drogerie markt, Germany's leading drugstore chain, in 2017, when Lehmann was only 14. His dad first invested in the brand in 1974, shortly after it was founded in 1973; it's since grown to own some 4,120 stores across Europe. Neither father nor son is involved with the company operations.
Though she doesn't have a role in the company, she and her sister (above) hold approximately 9% stakes in the game developer Nexon inherited through their late father. Gamers across 190-plus countries operate Nexon's slate of over 80 live games, including hits like MapleStory, KartRider and Dungeon & Fighter.
Like his siblings (above), he owes his wealth to his 12.5% ownership of the holding company Delfin, which has a stake in EssilorLuxottica, the eyeglass company behind shade offerers like Arnette, Ray-Ban and Persol. He has no role at EssilorLuxottica. He and his brother Luca (above) are the two children his late father had with the company's former head of investor relations, Sabina Grossi.
Voigt is the youngest billionaire heir of WEG cofounder Werner Ricardo Voigt and owns a 3.1% stake in the company, like her sister (above). She is currently studying psychology at university. After Forbes named her the world's youngest billionaire last year, she shared on social media that she wished to avoid attention and would keep a low profile online.
Johannes is the youngest heir to the German pharmaceutical company Boehringer Ingelheim. The family is notoriously publicity-shy, and it's unknown whether he or his three siblings (above) have any role at the company. The drugmaker has been led by a family member—Johannes' uncle, Hubertus von Baumbach—since 2015. Johannes skis competitively in Austria.

Meta Platforms (META) Reportedly Held Acquisition Talks with Perplexity AI
Meta Platforms (META) reportedly held acquisition talks with Perplexity AI, an artificial intelligence search startup, before ultimately deciding to invest heavily in another AI company, Scale AI. According to Bloomberg, the discussions between Meta and Perplexity did not result in a deal, and both companies walked away without pursuing the acquisition. Neither Meta nor Perplexity have commented publicly on the matter. Confident Investing Starts Here: Easily unpack a company's performance with TipRanks' new KPI Data for smart investment decisions Receive undervalued, market resilient stocks right to your inbox with TipRanks' Smart Value Newsletter Instead, Meta announced earlier this month that it would invest $14.3 billion in Scale AI, which allowed it to acquire a 49% stake in the company and value it at over $29 billion. As part of the deal, Scale's CEO Alexandr Wang will join Meta to lead its new 'superintelligence' division, which focuses on developing artificial general intelligence (AGI). For context, AGI refers to AI systems that can understand, learn, and apply knowledge across a wide range of tasks at a human-like level of intelligence. This move highlights Meta's shift toward building more advanced AI systems that go beyond narrow task-based models. Founded in 2016, Scale AI helps train generative AI models by connecting them with a large network of human experts. Meta's significant investment in the company shows that CEO Mark Zuckerberg is determined to strengthen the company's position in the AI market. And Zuckerberg is not the only one, as many other tech giants have invested heavily in AI startups ever since Microsoft's blockbuster deal with OpenAI in 2023. Is Meta a Buy, Sell, or Hold? Turning to Wall Street, analysts have a Strong Buy consensus rating on META stock based on 42 Buys, three Holds, and one Sell assigned in the past three months, as indicated by the graphic below. Furthermore, the average META price target of $707.16 per share implies that shares are almost fairly valued.

Barron Trump made millions from family's lucrative crypto firm: report
Barron Trump, the youngest son of the 47th President, may have raked in millions of dollars from the sale of crypto tokens linked to the family's lucrative venture into digital tokens, according to report. The 19-year-old New York University student could have picked up a cool $40 million — $25 million after taxes — from the sale of digital assets by World Liberty Financial Group, the Trump family firm launched nine months ago after Barron persuaded his dad about the benefits of crypto, Forbes reported. 'Barron knows so much about this,' commander-in-chief said during an interview in September after the launch. 'Barron's a young guy, but he knows it — he talks about his wallet. He's got four wallets or something, and I'm saying, 'What is a wallet?'' Barron Trump, seen here at his father's second inauguration, is listed as a 'co-founder' on World Liberty Financial's website. AFP via Getty Images World Liberty has been a financial bonanza for the family. In March, World Liberty announced that it had sold $550 million worth of tokens. An Office of Government Ethics filing released by President Trump last week declared he had made $57 million from token sales. It also said that the real estate mogul held a 75% stake in his umbrella company, DT Marks Defi LLC, with unnamed 'third parties' holding the other 25%. Barron Trump is listed as a 'co-founder' of World Liberty Financial alongside the president, as well as Eric and Donald Trump Jr, the president's two eldest sons. Forbes, which provided no direct evidence for its claims of Barron Trump's massive digital windfall, suggested that he owned a 7.5% stake in Delaware-based World Liberty. The stake would mirror what the NYU freshman holds in the Trump Organization's Washington, DC hotel, Forbes said. The Post has approached a Trump Organization spokesperson for comment. Trump once derided digital assets such as Bitcoin as 'a scam' but he has since U-turned and embraced cryptocurrencies. REUTERS Barron Trump's name does not appear in the company's solitary SEC filing from October 30 last year. Also listed as business partners in the venture are Middle East envoy Steve Witkoff and his son, Zachary. An analysis by Bloomberg, the financial news outlet, estimates the president's net worth has doubled since the start of his 2024 campaign, standing at just over $5.4 billion

Meta Plans to Poach AI Startup Safe Superintelligence's CEO After Failed Buyout, Report Says
Meta reportedly plans to hire Daniel Gross, CEO of Safe Superintelligence, and former Github CEO Nat Friedman. The pair run an investment firm, NFDG, which Meta intends to acquire a stake in. Last week, Scale AI CEO Alexandr Wang said he would also join Meta's AI development team. Meta's AI hiring blitz comes as CEO Mark Zuckerberg has reportedly been frustrated with the company's Platforms (META) is doubling down on its strategy of investing billions of dollars to poach top AI talent, with plans to add another AI startup CEO to its ranks. The Facebook parent plans to hire Daniel Gross, CEO of Safe Superintelligence, and former Github CEO Nat Friedman, according to reports citing The Information. The pair run an investment firm, NFDG, which Meta will acquire a stake in, the reports said. Safe Superintelligence was launched by former OpenAI research director Ilya Sutskever, who reportedly rebuffed Meta's attempts to hire him or buy the startup. When Sutskever declined, Meta turned to Gross. Meta, Safe Superintelligence, and Gross did not immediately respond to requests for comment. Gross and Friedman are expected to work under Alexandr Wang, the ex-CEO of Scale AI who just last week said he would join Meta's AI team. Meta also acquired a stake in the company worth billions of dollars. Meta's AI hiring blitz comes as CEO Mark Zuckerberg has reportedly expressed frustration with the company's progress in AI development. Last month, The Wall Street Journal reported Meta was pushing back the launch of its latest Llama 4 large language model amid concerns about whether enough improvements had been made compared to previous iterations. To speed up development, Zuckerberg is reportedly working to build what has been referred to internally at Meta as a "superintelligence group" that will sit near him at Meta's headquarters in Menlo Park, Calif. Shares of Meta were about 1% lower in recent trading. The stock has gained nearly 20% so far in 2025. Read the original article on Investopedia
