Brazil has banned 27 prediction market platforms, including Kalshi and Polymarket, due to new regulations categorizing many contracts as gambling. This decision, announced on April 25, 2026, marks a significant regulatory shift as the country seeks to tighten oversight in a sector previously lacking governance.
New Regulations Classify Prediction Markets as Gambling
The Brazilian government has taken a decisive step to regulate its prediction market sector, which had operated without oversight from 2018 to 2022. According to Dario Durigan, executive secretary of the Finance Ministry, “We have been monitoring the evolution of this sector in Brazil, which suffered a period of anarchy because there were no rules, no oversight.” The new regulations aim to protect consumers and prevent exacerbating financial issues among families and businesses.
Impact on Major Platforms and Market Reaction
Alongside Kalshi and Polymarket, other notable platforms such as PredictIt, Robinhood, and Fanatics Markets have also been banned. The new rules will take effect in early May 2026. This sweeping action targets the operational capabilities of these platforms, fundamentally altering the landscape. As the regulatory framework develops, market reaction has not been reported, but the implications for users and operators are substantial.
Broader Implications for the Crypto and Gaming Sectors
This regulatory change reflects a growing trend among governments to impose stricter regulations on digital financial products. By classifying prediction markets as gambling, Brazil joins a number of jurisdictions reevaluating their stance on related sectors, which may have far-reaching effects on both crypto and gaming industries. The launch of similar regulatory efforts by other nations could lead to worldwide changes in how prediction markets are treated legally.
Next Steps and Future Considerations
As the ban on these platforms takes effect, stakeholders will need to adapt to the evolving regulatory landscape. The Finance Ministry is likely to keep monitoring this sector closely, and the next milestone will be the enforcement of the new rules in May 2026. Ongoing scrutiny from regulators will shape the future of prediction markets in Brazil.
