Brazil is drawing a firmer legal line between financial contracts and bet-like products. The legal basis was reinforced by Resolution CMN No. 5,298, which narrows the permitted scope of derivatives in Brazil.
Under this rule, derivatives used within the country must be linked to economic and financial variables. These variables include price indexes, interest rates, exchange rates, commodity prices, financial assets, or securities traded in authorised markets. Contracts associated with sports results, election outcomes, and social, cultural, or entertainment events are no longer permitted as derivatives.
Derivatives Get a Narrower Definition
The resolution is set to come into force on May 4. It also reaches derivatives traded abroad when they are offered in Brazilian territory. This is significant for companies that operate global prediction markets. That limits the use of a common argument that offshore structure alone places these products outside Brazilian rules.
Platforms Face Blocking and Financial Pressure
The government has already started enforcement. According to CNN Brasil, 27 websites, including Kalshi and Polymarket, have been blocked in the country recently. The list also includes Robinhood, IBKR ForecastTrader, PredictIt, Voxfi, ProphetX, and several local prediction market brands.
These measures appear to be part of the government’s larger anti-illegal betting campaign. According to Brazil’s Finance Ministry, more than 39,000 irregular websites have been blocked and 203 betting apps have been removed. In addition, there have been 1,665 notifications sent out to financial institutions and payment institutions, along with 697 accounts connected to illegal betting operations being closed.
Following the same principle, the government is now targeting prediction platforms. According to the Finance Ministry, although these platforms can be perceived as financial products or contracts between users, they operate similarly to betting on future events. This makes them susceptible to regulation under already existing legislation.
Why Brazil Acted Now
Over the last few years, Brazil has been bringing the online betting industry out of the grey area and into a regulated, tax-paying industry. Authorities do not want prediction platforms to become a parallel route around the betting regime.
The decision is also linked to household debt concerns, which adds a consumer-protection dimension to it. According to the officials, if a product resembles betting, it cannot escape the regulations surrounding betting by using the language of finance.
What Remains Possible
The decision does not kill every form of prediction-based contract. Products tied to economic indicators can still operate, but they must stay inside the financial-market perimeter and follow the rules of authorised firms and regulators. Agência Brasil said the Securities and Exchange Commission of Brazil, the CVM, will handle complementary regulation and supervision for these permitted cases.
As of now, the country appears to be getting rid of the most popular categories through the derivatives route. How the regulation will affect the market will depend on whether Brazil can keep foreign access, payments, and marketing channels inside the same perimeter it is now trying to set.
