The National Association of Games and Lotteries (ANJL) has asked Brazil's Supreme Federal Court (STF) to overturn restrictions on fixed-odds betting advertising introduced by the Government of Minas Gerais.
The challenge, registered as Direct Action of Unconstitutionality 8014 and assigned to Justice Flávio Dino, concerns Decree 49.279/2026. ANJL argues that Minas Gerais exceeded its regulatory authority by imposing rules on an activity governed nationally and by regulating through decree a matter that it says requires legislation.
The decree prohibits direct and indirect advertising, commercial promotions and sponsorship by authorized fixed-odds betting operators on state-owned public assets and at events promoted or supported by the Minas Gerais executive.
The restriction also applies to structures under state administration, management or operation, including those subject to concessions or other forms of authorization.
It additionally bars public resources from directly or indirectly funding advertising covered by the restrictions and requires executive agencies to remove material that does not comply. The decree also covers adult-content platforms and sexual services.
ANJL argues that the measure creates different commercial conditions for operators participating in the same nationally regulated betting market. It is seeking the decree's invalidation and has also requested interim relief suspending its application.
The dispute comes as Brazil continues to expand federal controls over betting marketing. In July, the Ministry of Finance introduced mandatory risk warnings for fixed-odds betting advertisements, including messages warning that betting can cause dependence, result in financial losses and should not be treated as an investment.
A separate interministerial regulation broadened obligations across operators, advertising businesses and digital platforms. It prohibits advertising for unauthorized operators and requires checks confirming that advertisers hold authorization from the Ministry of Finance's Secretariat of Prizes and Betting.
Advertising directed at children and adolescents is also treated as abusive under the framework.
Brazil's regulated national market has operated under the current authorization system since January 2025, with federally licensed brands required to use .bet.br domains.
ANJL was also admitted as amicus curiae in ADIs 7,721 and 7,723, which are being considered alongside ADI 7,749 and challenge provisions of Brazil's Betting Law.
Minas Gerais lawmakers are separately considering proposals addressing betting advertising, including restrictions involving sports venues, digital marketing and areas used predominantly by minors
