Luana Lopes Lara, the world’s youngest self-made woman billionaire at 29, has captured global attention with the extraordinary rise of her prediction market startup, Kalshi. Born and raised in Brazil, Lara grew up dreaming of becoming the next Steve Jobs. Her parents, a math teacher mother and an electrical engineer father, encouraged both her academic drive and artistic ambitions. She excelled in school, winning medals at the Brazilian Astronomy Olympiad and the Santa Catarina Mathematics Olympiad, while also training rigorously in ballet at the prestigious Bolshoi Theatre School.
After high school, Lara moved to Austria to perform as a professional ballerina, an experience she later described as more intense than her years at the Massachusetts Institute of Technology. Although ballet had shaped her discipline and resilience, she chose to leave the stage to pursue a degree in computer science at MIT. During her time there, she interned at top financial firms, including Bridgewater Associates, Citadel and Five Rings Capital. These early experiences deepened her interest in financial markets and helped lay the groundwork for her future venture.
Kalshi was founded in 2018 by Lara and her MIT classmate Tarek Mansour. The idea emerged one night in New York City while the two were returning home from their internships. Both had noticed that traders constantly relied on predictions about external events to guide investment decisions. They wondered why there was no direct way to trade on the outcomes of future events themselves. That question became the seed for Kalshi, a platform that allows users to trade on everything from elections and inflation data to sports results and cultural moments.
The cofounders were determined to build the world’s first federally regulated prediction market, but the path was far from straightforward. The legality of operating such a platform in the United States was unclear, and few law firms were willing to help an early-stage startup navigate complex federal regulations. After reaching out to dozens of firms without success, they eventually connected with Jeff Bandman, a former official at the Commodity Futures Trading Commission. With his guidance, the founders applied for regulatory approval. In 2020, Kalshi became the first platform of its kind to be approved by the CFTC as a designated contract market.
The battles did not end there. In 2023, regulators rejected Kalshi’s proposal to introduce election-based contracts, arguing that they resembled gambling. The company challenged the decision in court, and in 2024, just two months before the US presidential election, a federal judge ruled in Kalshi’s favour. This landmark ruling allowed the company to legally offer election contracts in the United States. Users traded more than 500 million dollars on the platform during the election cycle and accurately predicted Donald Trump’s victory.
Kalshi’s growth since then has been rapid. The company has raised significant funding, pushing its valuation to around 11 billion dollars in less than six years. Lara holds an estimated 12 per cent stake, giving her a personal net worth of roughly 1.3 billion dollars. The platform’s trading volume has risen sharply, now surpassing one billion dollars every week, driven largely by sports-related contracts, which make up about 90 per cent of total activity.
The company has also expanded through major partnerships. Kalshi has integrated with brokerages like Robinhood and Webull and has formed collaborations with organisations including the National Hockey League, StockX and Google Finance. Donald Trump Jr joined the board earlier this year, further boosting the firm’s public profile. The platform is now preparing to move into cryptocurrency-linked prediction markets, positioning itself to compete with existing players such as Polymarket.
With new capital, regulatory momentum and growing mainstream visibility, Kalshi aims to push deeper into global markets, strengthen its integration with financial platforms and build partnerships with media organisations. For Lara, the journey from ballerina to billionaire entrepreneur reflects a blend of discipline, ambition and persistence that continues to shape one of the most talked-about startups in the world.
