NextFin News - A legislative blockade in Brasilia has stalled the ambitious expansion of Kalshi, the New York-based prediction market, into the Brazilian market. Luana Lopes Lara, the 29-year-old co-founder of Kalshi and recently minted billionaire, is facing a formidable challenge from Brazilian lawmakers who are moving to classify event-based trading as illegal gambling. The friction highlights a growing global regulatory divide over whether prediction markets are sophisticated financial hedging tools or merely high-tech sportsbooks.
The primary obstacle is a new bill introduced in the Brazilian Senate by Tasso Jereissati, a veteran politician known for his fiscally conservative but socially cautious stance. Jereissati, who has long advocated for strict oversight of the financial sector to prevent systemic volatility, argues that prediction markets exploit retail investors by masking speculative betting as legitimate economic activity. His proposed legislation seeks to ban any platform that allows contracts on non-financial real-world events, a move that would effectively shutter Kalshi’s operations in South America’s largest economy before they can fully scale.
Lopes Lara, who was born in Brazil and trained at the Bolshoi Ballet School before moving to the United States to study at MIT, has built her career on the premise that "everything is a trade." After stints at Bridgewater Associates and Citadel Securities, she co-founded Kalshi in 2018 with Tarek Mansour. The firm’s valuation surged to $11 billion in late 2025 following a $1 billion funding round, making Lopes Lara the world’s youngest self-made female billionaire. Her strategy has always centered on regulatory compliance, having spent years securing a federal license from the U.S. Commodity Futures Trading Commission (CFTC).
However, the Brazilian regulatory environment is proving less hospitable than the U.S. under the current administration. While U.S. President Trump has overseen a CFTC that is generally supportive of prediction markets—bolstered by strategic advisors like Donald Trump Jr., who has ties to the industry—Brazilian authorities are taking a more restrictive path. Jereissati’s bill reflects a broader skepticism within the Brazilian Senate, where many lawmakers view the rise of "event contracts" as a threat to public order and consumer protection. This perspective is not a fringe view; it aligns with recent moves by several U.S. states, including Utah and Nevada, which have also moved to block Kalshi on similar grounds.
The debate in Brazil mirrors the legislative battle currently unfolding in Washington. Senators Adam Schiff and John Curtis recently introduced the "Prediction Markets are Gambling Act," which aims to ban contracts related to sports and other "socially sensitive" events. If both the Brazilian and U.S. legislative efforts succeed, the total addressable market for Kalshi could shrink by as much as 40%, according to preliminary estimates from industry analysts. For Lopes Lara, the stakes are personal and professional, as Brazil was intended to be the cornerstone of Kalshi’s international growth strategy.
Critics of the ban, including some fintech advocates in Sao Paulo, argue that Jereissati’s approach is reactionary. They contend that prediction markets provide valuable data on public sentiment and economic expectations that traditional polling and financial instruments cannot capture. Yet, the momentum in the Brazilian Senate suggests that the "gambling" label is sticking. Without a significant pivot in lobbying strategy or a compromise that limits the types of contracts offered, Kalshi’s Brazilian venture may remain frozen in the legislative committee stage for the foreseeable future.
