Highlights:
- Brazil prediction markets ban shuts 28 sites, bars country access
- New rules on derivatives only allow economic indicator contracts
- The government cites debt risks and regulatory oversight between 2018 and 2022 for the ban
A regulation prohibiting the use of prediction markets in Brazil has been put in place by implementing a new regulatory system that will limit access to certain prediction and betting websites.
The move was made following the enactment of the Banco Central do Brasil’s rules on derivatives and is in accordance with the provisions set out in Resolution 5.298 from the National Monetary Council. After implementing the regulation, sites like Polymarket and Kalshi were blocked in Brazil.
What are the updated regulations on the Brazil Prediction Market Ban?
New regulations have been put in place under the Brazilian prediction market ban regarding derivative contracts whose underlying asset is associated with non-economic events. The new regulation bans derivative contracts whose underlying asset is associated with sports, political events, entertainment, or social events.
Derivative contracts that cannot be regarded as economic or financial benchmarks were defined by regulators and thus deemed illegal under the new regulations. These regulations require that only derivative contracts associated with economic indicators be allowed and that the following can be used as the underlying benchmark:
- Inflation rate
- Interest rate
- Exchange rate
- Commodity price
The rules make the difference between financial derivatives and event contracts very clear, as the latter are no longer recognized in regulated markets.
Platforms Affected by the Brazil Prediction Markets Ban
The enforcement of the Brazilian ban on prediction markets has led to access restrictions across a wide range of platforms. Finance Ministry officials reported that approximately 28 services were impacted by the decision.
Among the affected platforms are:
- Polymarket and Kalshi
- PredictIt and Robinhood’s forecasting feature
- Fanatics Markets, ProphetX, Hedgehog Markets
- Novig, Polyswipe, PRED Exchange, and Stride
Brazil-based platforms were also included, such as Palpita, Cravei, Previsao, and MercadoPred.
Access to these services was reported as unavailable within Brazil following the regulatory action. Authorities did not disclose the technical mechanisms used to enforce the restrictions, but confirmed that the measures are part of compliance enforcement.
Government Position on Consumer Protection and Debt Risks
Officials linked the ban on Brazil prediction markets to broader financial oversight objectives. Finance Ministry Executive Secretary Dario Durigan stated that authorities had monitored the sector’s development over several years, particularly from 2018 to 2022.
Durigan reported that the sector operated without sufficient oversight during that time, allowing platforms to expand outside formal regulatory structures. He said that the rules were designed to plug these gaps and ensure consistency with financial market practice.
In addition, other concerns have been raised about financial risk exposure. The prediction market is claimed to be one of the sources of increased financial risk for people in the country. These restrictions were seen as a way to reduce debt for families, students, and small businesses.
Impact of Brazil’s Prediction Markets Ban on Market Structure
Under the Brazilian prediction markets ban, the government sets regulations that differentiate the financial tool from event trading. To qualify as a derivative under the new regulation, there must be economic data supporting it.
Those that are dependent on random or non-economic events will not be considered under this category by the regulators, who said their approach would ensure the financial markets remain focused on benchmarked instruments.
The central bank mentioned issues related to market integrity, noting that non-compliant contracts may pose risks to market participants. By restricting the range of acceptable contracts, the range of trading possibilities is reduced.
Global Environment Concerning Restrictions on Prediction Markets
The Brazilian prediction markets ban follows similar trends in other regions. For instance, France, Belgium, and the Netherlands have banned the use of prediction markets without proper authorization.
On the contrary, in the USA, there is still a divide on this topic among federal regulators and the different states. Different states in the USA have adopted conflicting views about prediction markets, hence creating legal issues. The CFTC in the USA has a favorable position concerning some prediction markets.
The methods above highlight the differences in the classification and regulation of prediction markets across jurisdictions.
What the Implementation Means for the Future
The Brazil prediction market ban is set to take effect at the beginning of May, following the adoption of Resolution 5.298. These rules apply to all old contracts and any new contracts entered into.
Platforms operating in Brazil should comply with these changes or remove any prohibited products. Economic indicator contracts will still be allowable, but event contracts will no longer be allowed.
Conclusion
With the ban placed on prediction markets in Brazil, there is now a definite framework that restricts any event-related contracts or even access to such platforms within the country.
