She has $2.6 billion but still works 14 hours a day: Why the world’s youngest self-made woman billionaire can't slow down

Having billions of dollars in the bank might sound like the perfect reason to take a break from work. But for Luana Lopes Lara, the 30-year-old co-founder of prediction market platform Kalshi, becoming a billionaire has done little to change her daily routine. She still works for as long as 14 hours a day, remains focused on building her company and rarely takes time off.

Lara, who has an estimated net worth of $2.6 billion, has earned the distinction of being the world's youngest self-made female billionaire. Yet, she says her wealth has not dramatically changed the way she lives. Her attention remains firmly on the business she helped build rather than on the luxuries her fortune could buy. In an interview with Fortune, Lara explained why her billionaire status has not altered her priorities. For her, the biggest motivation has always been growing Kalshi, and that ambition continues to shape her everyday life.

Why $2.6 billion has not changed her lifestyle

Lara believes her intense focus on work explains why becoming extraordinarily wealthy has not made much difference to her lifestyle. Speaking to Fortune Daily's Ellie Austin, she said she had always been deeply committed to building Kalshi. That focus, she suggested, matters more to her than the financial rewards that have followed the company's growth.


Her spending habits have largely stayed the same. She may occasionally choose a more expensive lunch simply because she wants to enjoy a good meal, but she has not described a major shift towards an extravagant lifestyle.

For Lara, money has opened the door to certain experiences without becoming the centre of her life. She has treated her family to a Christmas Mass at the Vatican and sometimes spends money on meals with friends. Beyond such occasions, however, her attention remains on the company.

Coming from a middle-class family in Brazil, Lara has also spoken about finding her billionaire status difficult to fully comprehend. Her journey from aspiring ballerina to technology entrepreneur has been an unusual one, and her financial success represents a dramatic change from her early years. Still, the wealth itself does not appear to have changed the goal that drives her: building Kalshi into a bigger business.

From professional ballet training to building a billion-dollar company

Lara's path to becoming a billionaire did not begin in a technology startup. Before entering the business world, she trained as a professional ballerina in Brazil. She eventually moved into technology and co-founded Kalshi with Tarek Mansour. The company operates a prediction market platform where users can trade contracts linked to the outcomes of real-world events.

These contracts cover a wide range of subjects, including elections, sporting competitions and economic developments. The idea is to let people take positions on what they believe will happen, with market prices reflecting changing expectations.

Kalshi's growth has helped turn Lara into one of the most prominent young entrepreneurs in the prediction market industry. Its rising valuation has also brought greater attention to the business model and the regulatory questions surrounding it. For Lara, however, the company's financial milestones have not replaced the work itself as her primary focus.

Kalshi's valuation has surged to billions of dollars

Kalshi's valuation has climbed rapidly as investor interest in prediction markets has increased. The company was valued at $2 billion in June 2025. That figure rose to $11 billion by December 2025 before reaching $22 billion in May 2026.

The momentum continued into the second half of the year. According to a Reuters report cited in the original coverage, Kalshi was in discussions in September to raise another $1 billion at a valuation of around $40 billion. Such a valuation would mark a significant jump for a company that has built its business around trading contracts tied to the outcomes of events.

However, a company's valuation is not the same as the amount of cash its founders hold. Lara's estimated $2.6 billion net worth is linked to the value of her ownership and other assets, rather than necessarily representing money available in a bank account. The company's expansion has also placed its business model under closer scrutiny.

Why Kalshi is facing legal challenges in the US

Kalshi's rapid growth has not come without obstacles. Several US states have challenged its sports-related contracts, arguing that they amount to illegal gambling and should be subject to state gambling laws. The company disputes that interpretation. It maintains that Kalshi operates as a federally regulated financial exchange rather than a conventional sportsbook.

The distinction is important because the legal treatment of prediction markets can determine which products a platform is permitted to offer and what regulatory requirements it must meet. Lara has defended the company's approach, arguing that prediction markets can provide useful forecasts by bringing together people who are willing to put money behind their expectations.

In comments to Fortune Daily, she also distinguished Kalshi's business model from that of a traditional sportsbook, saying the company does not make money in the same way. The disputes could have wider implications for the prediction market industry as platforms seek to expand into sports and other areas that have traditionally been associated with betting. Kalshi co-founder and CEO Tarek Mansour has suggested that the ongoing regulatory battle could eventually reach the US Supreme Court.

Why the billionaire continues to work long hours

Lara's routine offers a different picture of what life can look like after reaching extraordinary financial success. Despite her estimated $2.6 billion fortune, she has continued to work 12 to 14 hours a day and rarely takes time off. Her explanation is rooted in the commitment she has maintained towards Kalshi since its early days. Rather than treating wealth as a reason to step away, she appears to see the company's progress as a continuing challenge.

Her story also highlights the difference between financial independence and the desire to keep building something. For Lara, becoming a billionaire has brought recognition and new opportunities, but it has not removed her appetite for work. As Kalshi pursues further growth while dealing with regulatory challenges, the entrepreneur's focus remains on the business. The fortune may be worth billions, but for now, it has not persuaded her to slow down.
