The National Association for Legal Security of Games and Bets (Anseja) has challenged Brazil's new betting prohibition before the Supreme Federal Court (STF), becoming the latest industry group to seek the suspension of Provisional Measure 1.394/2026.
Anseja filed Direct Action of Unconstitutionality (ADI) 8024, arguing that the measure lacks the urgency required for a provisional measure and raises questions over legal certainty, free enterprise and Brazil's federal structure. It has requested the full suspension of the measure and restoration of the previous regulatory framework.
The National Association of Games and Lotteries (ANJL) has separately filed ADI 8027. Both challenges come as the Government begins dismantling a regulated market that became operational in January 2025 under legislation passed in 2018 and 2023.
MP 1.394 prohibits the operation, offering, intermediation and advertising of fixed-odds betting across Brazil. It covers sports betting and online gaming while excluding other lottery products authorized by law.
Existing federal, state and Federal District authorizations are due to expire 30 days after the measure's September 25 publication. Access to betting websites and applications must be disabled within 10 days.
The measure has already entered Congress, where lawmakers will determine whether the prohibition continues beyond its provisional status.
Anseja is alternatively seeking a transition period of at least 180 days. It also wants website blocking and forfeiture of funds to require a court decision.
The legal challenges arrive shortly after the Ministry of Finance had continued strengthening the regulated system. On September 14, its Secretariat of Prizes and Betting announced expanded procedures targeting payment transactions connected to unauthorized operators. Its 2026 regulatory agenda had also included revisions to operator authorization procedures and controls against illegal betting payments.
The STF was already considering constitutional cases involving Brazil's betting framework before the new measure. ANJL and the Brazilian Institute of Responsible Gaming (IBJR), participating in existing proceedings, have asked the court to consider the prohibition alongside those cases.
The challenges follow wider opposition to the ban from parts of Brazil's betting ecosystem. Content creators who had promoted betting operators criticized the measure publicly, including warnings that players could migrate toward unregulated platforms.
MP 1.394 also establishes an interinstitutional committee responsible for coordinating enforcement against illegal fixed-odds betting and advertising
