Federal SPA (Secretaria de Prêmios e Apostas), Ministry of Finance; State consumer authority Procon-MT proposed for oversight in draft bill

Federal: Law 14.790/2023 (fixed-odds betting, online games); State: unconfirmed (various bills under discussion)

Not confirmed. Draft law would prohibit advertising, sponsorship and promotion of electronic gambling games and certain bets, except for lotteries or private operators legally authorised under federal law.

Multiple draft state bills aim to restrict or prohibit gambling advertising, especially for electronic gambling, elections-related betting and online bets, but enactment status and scope remain uncertain.

National rules also apply — see online gambling regulation in Brazil.

We could not confirm a public list of licensed operators.

• State bill to regulate advertising and sponsorship of fixed-odds sports betting platforms (bets) introduced in Mato Grosso legislature
• State bill to prohibit advertising and sponsorship of electronic gambling and bets on elections, referendums and plebiscites, with carve-out for authorised lotteries and licensed operators
• State bill to restrict public agents’ access to online betting, casinos and other gambling on state-owned equipment and premises
• Draft complementary law to create a state supervision fee (TFAJ) for all betting and gambling, including online casinos and fixed-odds bets, assigning oversight to Procon-MT

• Whether Mato Grosso has formally launched state-level licensing or accreditation for online fixed-odds sports betting operators
• Whether any SPA-authorised operators have gone live in Mato Grosso and on what exact date
• Exact status (enacted or pending) and numbering of the state bills identified only as draft texts in Assembly documentation
• Whether Mato Grosso has any state-level enforcement or consumer rules affecting online sweepstakes/social casinos, loot boxes, or prediction markets.
• Whether Brazilian regulators would classify specific mystery-box or sweepstakes mechanics as fixed-odds betting, lottery, or consumer promotions.
• Whether any local courts or prosecutors in Mato Grosso have addressed Polymarket/Kalshi-style markets specifically.
