BroadChain learned that at 19:02 on April 25, the Brazilian Ministry of Finance, in coordination with the National Telecommunications Agency (Anatel), announced the blocking of 27 prediction market platforms, including Kalshi, Polymarket, PredictIt, Robinhood's prediction features, and Fanatics Markets, based on Resolution No. 5298 of the National Monetary Council (CMN). The ban will take effect in early May.
The new regulations explicitly prohibit prediction contracts involving sports, politics, entertainment, or social events, classifying them as closer to gambling rather than financial investments. Only contracts linked to economic indicators such as inflation, interest rates, exchange rates, and commodity prices are allowed to continue operating. Dario Durigan, Executive Secretary of the Ministry of Finance, pointed out that prediction markets may exacerbate the debt burden of households and small and medium-sized enterprises, posing financial risks.
Currently, similar restrictions have been implemented in countries such as France, Belgium, and the Netherlands.
