Brazil’s betting ban creates legal uncertainty for sports sponsorship contracts

Brazil’s Medida Provisória nº 1.394, dated September 25, 2026, does more than shut down fixed-odds betting. It also hits sponsorship, marketing, and commercial agreements that were built around a regime the state had already authorized, which is where the legal mess starts for clubs, suppliers, and payment-adjacent businesses.

1. The betting sector in Brazil was regulated first by Lei nº 13.756/2018 and then by Lei nº 14.790/2023, which set rules for fixed-odds betting and operating requirements for companies. From January 2025, national operations were conditioned on authorization from the Secretaria de Prêmios e Apostas do Ministério da Fazenda.
2. The new provisional measure changes that structure materially. It prohibits the operation, offering, and intermediation of betting, and article 16 also bans communication, advertising, promotion, marketing, and sponsorship tied to the sector. It requires betting-related advertising materials and sponsorship signs to be removed within ten days of publication.
3. Article 4 goes further and terminates authorizations granted to operators after thirty days. For businesses that signed contracts, budgeted around those authorizations, or made investments tied to them, the legal question is no longer theoretical: the effects are immediate.
4. The dispute now sits at the point where state regulatory power meets contracts signed under the prior law. The Brazilian Constitution protects free enterprise, legal certainty, and the protection of perfected legal acts, but the text also makes clear that there is no acquired right to keep the same legal regime forever. The pressure point is how far a new law can go when it reaches contracts already in execution.
5. Sports sponsorship agreements are the obvious test case. In practice, these contracts usually include brand exposure, periodic payments, advertising rights, and commercial consideration. Once brand promotion is banned, part of the agreed performance disappears, and each contract has to be assessed on its own to determine what survives and what does not.
