In a decisive move to regulate the country’s rapidly evolving digital wagering landscape, the Brazilian Ministry of Finance has officially prohibited 27 prediction markets from operating within national borders.
The enforcement action follows an extensive audit which concluded that these “prediction market” models were functioning as gambling betting sites without the necessary legal authorizations.
The “Prediction Market” Loophole
According to government officials, the targeted companies frequently marketed their services as financial investments or trades in derivative instruments.
However, regulatory agencies determined that the underlying mechanics, allowing users to wager on political decisions, economic indicators, and cultural phenomena, mirrored traditional gambling without adhering to Brazil’s strict consumer protection rules.
The scope of prohibited bets was vast, including:
- Political Outcomes: Betting on election results in the USA, Venezuela, and Israel.
- Geopolitical Events: Wagering on the outcome of military conflicts.
- Social Trends: Predicting winners of arts, music, and gaming tournaments.
CMN Resolution and the Derivatives Market
This crackdown aligns with a new resolution adopted by Brazil’s National Monetary Council (CMN) on April 24. The mandate specifies that only derivatives tied to actual financial or economic indicators under the supervision of the Securities and Exchange Commission (CVM) are permitted.
By banning prediction markets like Kalshi and Polymarket, the Brazilian government aims to prevent an “unregulated parallel market” that exposes users to significant financial risk and potential over-indebtedness.
Crucially, this prohibition does not impact legally licensed sportsbooks or online casinos, which operate with predetermined odds. In contrast, prediction platforms settle contracts based on uncertain real-world outcomes that fall outside the scope of current betting legislation.
Organizations currently facing bans must now choose between adapting their entire business model to meet Brazilian legal standards or exiting the territory entirely to avoid further sanctions.
