The Youngest Billionaires In The World 2026 | Forbes

There are more Gen Z billionaires than ever before. A record 35 people managed to hit the 10-digit fortunes before age 30 on Forbes' latest World's Billionaires list. That's only 1% of the planet's 3,428 billionaires. They got wealthy in everything from drug stores and plumbing supplies to prediction markets and AI vibe coding. In all, the 35 super-rich, super-youngsters on the list are worth $92.4 billion. Here are 5 of the youngest billionaires to make Forbes' 2026 World's Billionaires list. Lopez Lara is the world's youngest self-made woman billionaire. The Brazilian native unseated 31-year-old scale AI co-founder Lucy Guo, who had taken the title from Taylor Swift. After graduating high school, she performed as a professional ballerina in Austria for nine months before leaving to attend MIT. As the co-founder and COO of prediction market firm Calshi, she owns an estimated 12% of the company. Surya Mehta, co-founder of AI recruiting startup Mercor, beat out his two co-founders Brendan Foody and Adarsh Hiramath to become the youngest self-made billionaire by two months. Born to Indian immigrant parents, Mehta was born in California's Bay Area and was a national debate champion in high school. He and his 22-year-old co-founders each own an estimated 22% stake in the company and are the youngest self-made billionaires ever to make Forbes' billionaires list, beating out Mark Zuckerberg, who debuted at age 23 two decades ago. Alexander Wang is the founder of AI data labeling giant Scale.AI. In June, Facebook parent company Meta bought 49% of Scale for around $29 billion, and Wang became Meta's chief AI officer. He was the world's youngest self-made billionaire until October 2025, when he was overtaken by PolyMarket founder Shane Coplin. Alexandra Andersson's fortune 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. Andersson and her 30-year-old sister sit on the board. She is a three-time junior Norwegian champion in dressage horse riding and both owns and runs the Oslo horse breeding stable Andersson Dressage. The world's new youngest billionaire of all is Amelie Voigt Trehas, whose late grandfather Werner Ricardo Voigt co-founded the Brazilian industrial machinery giant W.E.G. in 1961. At just 20 years old, Trehas owns 2% of W.E.G. and is worth an estimated $1.1 billion.
