Brazil Just Drew the Line on Prediction Markets
Brazil has officially declared prediction markets illegal. On April 24, 2026, Finance Minister Dario Durigan and Chief of Staff Miriam Belchior held a press conference to announce that the National Monetary Council (CMN) adopted Resolution 5,298 the previous evening. The resolution explicitly excludes sporting events, virtual online gaming events, and real or virtual events of a political, electoral, social, cultural, entertainment, or any other nature from permissible underlying assets for derivatives contracts. The rule takes effect May 4, 2026.
The decision removes any remaining ambiguity. Anatel, Brazil’s national telecommunications agency, has already blocked 28 platforms offering event contracts. Officials made clear that additional sites will face the same fate. This move follows the blocking of 39,000 unlicensed betting sites since the regulated market launched in January 2025.
The announcement signals a deliberate regulatory tightening. Brazil is refining its framework under Law 14.790 and choosing not to extend it to prediction markets. For global operators and investors assessing LATAM entry, the implications are immediate and structural.
The Regulatory Mechanics of the CMN Resolution
Dario Durigan was categorical. He stated that bets on random events, such as weather conditions, do not comply with the laws passed for sports betting and online gaming. Platforms are being blocked to prevent uncontrolled growth and risks to the population.
Miriam Belchior framed the decision as consumer protection. “Now, we are announcing that prediction markets will not be allowed in Brazil. We do not want to expose Brazilians to risks and financial losses.”
Regis Dudena, Secretary of Economic Reforms, reinforced the boundary. Betting not related to sporting events and online games was excluded from regulation. Any other type of betting is prohibited. The CMN resolution directly responded to attempts to present prediction activity as securities or derivatives.
Daniele Correa Cardoso, Secretary of Prizes and Betting, added clarity. Fixed-odds betting remains legal and regulated as a public service. Authorized platforms must follow established rules. Prediction platforms, she said, entered the market offering bets disguised as derivatives. This is illegal and not recognized under Law 14.790.
The resolution was authorized by Central Bank governor Gabriel Galípolo and limits permitted derivatives to economic and financial benchmarks: interest rates, exchange rates, stock market indices, commodity prices, GDP, inflation, unemployment, and Bitcoin and crypto coins.
Operational Impact on Global Operators Entering LATAM
Operators considering Brazil must now treat prediction markets as off-limits. The resolution applies regardless of whether a platform frames contracts as derivatives, securities, or event-based wagers. Anatel blocking orders are already active and will expand.
This creates immediate operational risk. Kalshi‘s recently announced partnership with XP International to enter Brazil now sits in legal limbo. Polymarket faces the same prohibition. Companies that launched or planned Brazilian offerings face swift site blocking and potential enforcement actions.
Global operators with multi-jurisdictional strategies must reassess product roadmaps. What works in jurisdictions that treat event contracts as derivatives may trigger enforcement in Brazil. Compliance teams will need to audit language, product design, and user acquisition tactics for any LATAM exposure.
Financial and Market Implications
Brazil’s regulated betting market has grown rapidly since January 2025. Officials clearly intend to protect that channel by preventing leakage into unregulated prediction activity. By excluding these products, the government aims to concentrate activity inside the licensed, taxed, and monitored ecosystem.
For operators, the financial signal is twofold. First, prediction market revenue streams that some hoped would diversify LATAM portfolios are now foreclosed in Brazil’s largest market. Second, the aggressive blocking of 39,000 unlicensed sites demonstrates enforcement capacity. Capital deployed on market entry without clear regulatory cover carries higher burn risk.
Investors evaluating prediction market pure-plays or hybrid operators must now assign higher jurisdictional risk premiums to Brazil. The country that many viewed as an emerging vertical beachhead has chosen a narrower interpretation of permissible gaming.
Risk, Counterarguments, and Potential Limitations
The government’s consumer-protection rationale deserves scrutiny. Ricardo Morishita, national consumer secretary, warned that illegal betting poses immense risk and directed players toward regulated sites carrying the bet.br domain.
The decision is not uncontested. The Novo party filed a Legislative Decree Project in the Chamber of Deputies on April 24, led by deputy Gilson Marques, arguing that the CMN exceeded its remit by imposing broad restrictions without clear legal basis and that the rule limits public access to information generated by prediction markets. A PDL is the parliamentary instrument used in Brazil to overturn an executive act, so the resolution faces legislative challenge from the start.
Prediction markets also bring transparency benefits in certain contexts. They can surface crowd-sourced probabilities on economic, political, and climate events. By closing the door entirely, Brazil may reduce certain speculative harms but also limit informational value that regulated versions could provide under strict oversight.
A risk for Brazil itself is over-exclusion. If legitimate hedging or information-discovery tools are swept into the ban, economic actors may seek gray-market workarounds. The same dynamic that officials fear with unlicensed betting could reappear in prediction form through VPNs or offshore platforms. Enforcement will need to remain consistent to prevent the very leakage the policy seeks to stop.
The Bottom Line
Brazil has removed prediction markets from both the derivatives and fixed-odds betting frameworks under Law 14.790. The CMN Resolution 5,298, effective May 4, 2026, backed by Dario Durigan, Miriam Belchior, Regis Dudena, Daniele Correa Cardoso, and Ricardo Morishita, combined with 28 platform blocks and the prior shutdown of 39,000 unlicensed sites, leaves no interpretive room.
This is an inflection point for LATAM regulatory risk. Global operators must treat Brazil as a closed door for event contracts and recalibrate forecasts accordingly. Other Latin American jurisdictions watching this enforcement model may adopt parallel restrictions, raising the compliance bar region-wide.
The constructive path forward lies in disciplined focus. Operators should prioritize markets with explicit regulatory cover, invest in transparent compliance architectures, and engage policymakers before product launches. Those who treat regulatory clarity as a non-negotiable input rather than an afterthought will be best positioned as Latin America’s gaming framework continues to mature.
