Luana Lopes Lara, the 30-year-old Brazilian entrepreneur who co-founded prediction market platform Kalshi, has built an estimated $2.6 billion fortune.
Yet her newfound billionaire status has done little to alter her daily life, with the former professional ballerina continuing to work up to 14 hours a day as the company expands amid growing regulatory scrutiny.
Lara, Kalshi’s co-founder and chief operating officer, discussed her demanding schedule and approach to wealth in an interview with Fortune Daily’s Ellie Austin. Despite becoming one of the world’s youngest self-made female billionaires, she remains focused on developing the business alongside co-founder and chief executive Tarek Mansour.
Her wealth is indicative of the quick growth in value of Kalshi, valued at $22 billion by May 2026. The success of the firm has put Lara among the ranks of technology entrepreneurs whose wealth is dependent upon platforms where people can trade on actual world events.
But financial success has not persuaded her to slow down.
Luana Lopes Lara reportedly spends between 12 and 14 hours working each day and rarely takes extended breaks. Rather than making substantial changes to her lifestyle, she has continued prioritising the responsibilities of running a fast-growing business.
Her spending habits have also remained relatively modest compared with her estimated wealth. She occasionally pays more for meals, enjoys dining with friends and has treated her family to a Christmas Mass at the Vatican.
Raised in a middle-class household in Brazil, Lara has acknowledged that becoming a billionaire remains difficult to fully comprehend.
Her professional background is unusual for a financial technology entrepreneur. Before entering the technology industry, she trained as a professional ballet dancer in Brazil. She later moved into entrepreneurship and established Kalshi with Mansour.
The company operates a prediction market where participants buy and sell contracts based on the outcomes of events, including political elections, sporting competitions and economic developments.
Contract prices change as traders respond to new information, providing a market-based indication of participants’ expectations about future outcomes.
Kalshi’s growth has attracted substantial investor interest.
The company was valued at $2 billion in June 2025 before its valuation climbed to $11 billion in December that year. By May 2026, the figure had doubled again to $22 billion.
Investor appetite appeared to remain strong in the following months. In September 2026, Reuters reported that Kalshi was in advanced discussions to raise approximately $1 billion at a valuation of around $40 billion.
While Kalshi’s expanding market presence has created considerable wealth for its founders, the company faces legal challenges that could influence its future operations.
Several US states have challenged Kalshi’s sports-related event contracts, arguing that the products constitute gambling and should therefore be governed by state gambling regulations.
Kalshi rejects that position. The company maintains that its event contracts are financial instruments regulated at the federal level by the Commodity Futures Trading Commission (CFTC).
The distinction is important because it could determine which authorities have jurisdiction over parts of Kalshi’s business and how the company can offer its products across the United States.
Lara has defended prediction markets as tools capable of combining information from large numbers of participants to generate forecasts that change in real time.
Mansour has also indicated that the dispute over state and federal authority could eventually reach the US Supreme Court.
For Lara, these challenges form part of the responsibility of building a company whose growth has significantly increased her personal wealth.
Her career has taken her from professional ballet training in Brazil to the leadership of a multibillion-dollar financial technology business.
Yet the defining feature of her current routine is not luxury or retirement, but the continued demands of growing Kalshi while navigating an uncertain regulatory environment.
Whether the company can sustain its rapid expansion will depend partly on how those legal disputes develop. For now, Lara remains closely involved in the business that made her a billionaire.
