Brazilian regulators on Friday moved to restrict so-called “prediction markets”—online platforms that allow users to place money on the outcome of real-world events—announcing a ban on election- and sports-related contracts offered by Kalshi and Polymarket, in a decision issued by the Secretaria de Prêmios e Apostas under the country’s Finance Ministry that places Brazil at the center of a rapidly escalating global regulatory battle.
The move comes as the United States is already grappling with the same issue through active litigation and regulatory conflict involving the Commodity Futures Trading Commission, which oversees Kalshi as a federally licensed exchange, and multiple state regulators who argue the platform is effectively offering unlicensed gambling. Federal court rulings have split on whether these contracts qualify as financial derivatives or bets, raising the likelihood that the issue could ultimately be decided by the U.S. Supreme Court.
At their core, prediction markets allow users to buy and sell contracts tied to future outcomes. In the U.S., those include whether inflation will exceed a certain level, whether the Federal Reserve will raise interest rates, whether a political party will control Congress, or outcomes of major sporting events. Rostin Behnam Chairman of the Commodity Futures Trading Commission has previously described event contracts as “novel financial products that require careful oversight,” while emphasizing the agency’s role in determining whether they fall within derivatives law.
Brazil’s action specifically targets contracts tied to elections and sports—categories regulators determined do not qualify as financial instruments under Brazilian law—and includes practical enforcement measures such as:
- Blocking access to platforms offering these contracts
- Prohibiting local financial institutions from facilitating payments
- Ordering partnered brokerages to halt distribution of restricted products
“These types of contracts are not compatible with the financial market framework,” the Secretaria de Prêmios e Apostas said in its official release, adding that such activities fall under Brazil’s betting laws and require proper licensing.
The restriction follows a joint review with the Comissão de Valores Mobiliários, which oversees capital markets but lacks jurisdiction over activities classified as gambling. Under Brazil’s legal structure, products tied to uncertain future events without an underlying economic asset—such as elections or sports—are categorized as betting.
The decision directly impacts Kalshi, which entered Brazil in March through partnerships with XP Inc. and Clear Corretora, initially offering macroeconomic contracts tied to inflation and interest rates while presenting the platform as a new financial asset class.
Co-founder Luana Lopes Lara, who is Brazilian, had identified the country as a strategic expansion market, citing its large retail investor base and growing digital trading ecosystem. The rollout, however, quickly collided with Brazil’s stricter legal separation between financial markets and betting.
Pressure from the domestic gambling industry also played a role. The Brazilian Institute for Responsible Gaming argued that prediction platforms operate similarly to sportsbooks but avoid licensing fees, taxation, and compliance requirements imposed on regulated operators, including strict identity verification and anti-money-laundering controls.
The broader regulatory backdrop includes a sharp rise in concern over gambling-related harm. The Brazil Ministry of Health has expanded national addiction programs, while authorities have blocked tens of thousands of illegal betting sites in recent years as part of a coordinated crackdown.
The broader regulatory backdrop includes rising concern among U.S. public health officials that prediction markets may expand access to gambling-like behavior under the framing of finance. “When products are presented as investing but function like betting, they can lower the psychological barriers to entry,” said Keith Whyte, Executive Director of the National Council on Problem Gambling, a Washington, D.C.-based nonprofit focused on prevention, treatment, and recovery. “For individuals vulnerable to addiction, these markets can become a gateway, where what starts as speculation can quickly turn into compulsive behavior.”
Public health authorities note that gambling-related harm is often self-identified rather than clinically diagnosed, with individuals recognizing patterns such as loss of control, financial strain, or repeated unsuccessful attempts to stop. The National Council on Problem Gambling and the World Health Organization recommend early intervention through confidential helplines, counseling, and self-exclusion programs; in the United States, the National Problem Gambling Helpline (1-800-GAMBLER), operated by the National Council on Problem Gambling, provides 24/7 confidential support, while similar resources have been expanded in Brazil through the Brazil Ministry of Health as part of a broader response to rising gambling-related concerns.
