Europe has a new entrant in a club still dominated by America. James Dacombe, a 25-year-old British entrepreneur who left school at 16, has become Europe’s youngest self-made billionaire after his artificial-intelligence chip company, Olix, raised $312m at a $3.3bn valuation.
Founded only in 2024, Olix is developing specialised chips for AI inference, the process by which trained models produce answers. Its latest Series B round included Arm, Hudson River Trading and Netflix co-founder Reed Hastings. Forbes estimates that Dacombe’s stake, alongside an interest in brain-monitoring venture CoMind, has pushed his fortune beyond $1bn. (OLIX)
“Meannwhile, China’s young fortunes span AI, gaming and consumer brands, while India now has eight self-made billionaires under 40 on Hurun’s measure”
He is not entirely alone. Sweden’s Fabian Hedin, 26, co-founded AI coding company Lovable, recently valued at $13.3bn, while fellow Swede Arvid Lunnemark, also 26, helped create Cursor. Their rise is beginning to change a European rich list traditionally populated by heirs rather than twenty-something founders. In March, Forbes counted 35 billionaires worldwide under 30; only 12 were self-made. (Forbes)
The striking point is geographical. Hurun’s 2026 ranking counted 108 self-made billionaires aged 40 or below. Fifty were in the United States and 29 in China; Britain had four. Together, America and China accounted for nearly three-quarters of the total. AI had become the single biggest wealth-producing sector for the group. (hurun.net)
America has gone further still. Mercor founders Surya Midha, Brendan Foody and Adarsh Hiremath became billionaires at 22 after their AI recruitment platform reached a $10bn valuation, overtaking the age at which Mark Zuckerberg first entered the billionaire ranks. The US ecosystem remains unusually effective at turning ambitious founders, venture capital and fast-rising valuations into personal fortunes. (Forbes)
Asia offers a broader mix. China’s young fortunes span AI, gaming and consumer brands, while India now has eight self-made billionaires under 40 on Hurun’s measure. Ritesh Agarwal, who started the company that became OYO while still a teenager, is now worth about $2bn as its parent prepares for a public listing. (Hurun)
Africa tells a different story. Forbes counts 23 African billionaires, 14 self-made, but all except Tanzania’s 50-year-old Mohammed Dewji are over 60. Its wealth remains concentrated in industry, telecoms, mining, finance and property rather than venture-backed software. (Forbes)
Dacombe’s fortune therefore says something larger. Europe may still produce fewer young billionaire founders than America or China, but AI is shortening the distance between an idea, a funding round and extraordinary wealth. Whether the technology ultimately justifies those valuations is the more consequential question.
