From Swan Lake to $11B: How a Ballerina Became the Youngest Self-Made Billionaire

Luana Lopes Lara, once a professional ballerina, has become the world’s youngest self-made female billionaire at just 29. Her fortune comes from Kalshi, the event-betting platform she co-founded with Tarek Mansour. The company’s rapid growth has pushed its valuation to an estimated $11 billion today. Lara began her career on stage, dancing at the Salzburg State Theatre. She performed leading roles, including the White Swan in Swan Lake, before shifting her focus to technology. After leaving ballet, she studied computer science at the Massachusetts Institute of Technology (MIT).

Together with Mansour, she launched Kalshi, a platform allowing users to bet on real-world events. The business faced early struggles, including regulatory hurdles and a temporary trading suspension in the U.S. Yet by the summer of 2025, Kalshi’s valuation soared to $2 billion in a major funding round. Her net worth now stands at around €1.1 billion, exceeding that of figures like Taylor Swift and Lucy Guo. Unlike Swift, whose wealth stems from music and branding, Lara built hers entirely through entrepreneurship and tech innovation.

Kalshi’s success has cemented Lara’s place among the youngest billionaires globally. The platform’s current valuation of up to $11 billion marks her as the youngest woman to achieve billionaire status without inheritance or family ties. Her journey from ballet to business highlights a rare shift from the arts to cutting-edge technology.
