Key Takeaways

• Brazil’s Ministry of Finance has blocked 27 platforms, including industry giants Kalshi and Polymarket, labeling them as illegal gambling.

• New regulations only allow contracts based on economic indicators like inflation; social and political betting are now strictly prohibited.

• Authorities cited the risk of “harmful indebtedness” among households as a primary reason for the aggressive crackdown.

Brazil has taken one of the most aggressive stances against prediction markets globally, officially blocking access to 27 different platforms. The National Telecommunications Agency (Anatel) executed the directive from the Ministry of Finance, effectively shutting down international and domestic favorites such as Polymarket, Kalshi, and PredictIt.

Finance officials described the previous four years as a period of “anarchy,” claiming that the lack of oversight had allowed unregulated gambling to flourish under the guise of financial forecasting.

Brazil flags prediction platforms

The primary driver behind the ban is a concern for the financial health of the Brazilian public. Executive Secretary Dario Durigan emphasized that at a time when the government is working to reduce debt levels for students and small businesses, prediction markets represent a new and dangerous avenue for “harmful indebtedness.”

Under the newly implemented Resolution 5.298, the National Monetary Council (CMN) has effectively bifurcated the market. Any contract tied to politics, entertainment, or sports is now classified as illegal gambling. Conversely, contracts linked to standard economic metrics—such as interest rates, commodity prices, or inflation—are permitted, provided they fall under strict financial market supervision.

More countries ban prediction markets

Brazil’s move reflects a growing international trend toward restrictive regulation. In Europe, countries like France and the Netherlands have already moved to penalize platforms operating without specific local authorizations.

The Brazilian crackdown specifically targets a wide range of services, including Robinhood’s forecasting feature and the sports-focused Fanatics Markets.

As more nations fold these platforms into their gambling frameworks, the “global” nature of prediction markets is being fractured. This trend suggests that unless platforms can prove they function as financial hedging tools rather than games of chance, their international footprint will continue to shrink.

Final Thoughts

Brazil’s decisive action proves that “financial inclusion” can be a double-edged sword. By prioritizing household debt reduction over market access, the government has set a firm boundary on where finance ends and gambling begins.
