Brazil Sues 43 Betting Firms Over Addiction Warnings

Brazil’s online betting sector is under fire, as a new civil lawsuit targets dozens of operators for not doing enough to warn users about the risks tied to gambling. The Public Defender’s Office in Rio de Janeiro is taking the issue to court, arguing that players are being exposed to harm without proper safeguards.

Good to know

• Brazil’s Chamber is considering a bill to send 0.1% of betting revenue to the national deaf sports federation.
• BR300M in damages is being sought to fund gambling addiction treatment and prevention.
• Lawsuit includes major platforms like Bet365, Stake, Betano, Pixbet, and Betfair.

The lawsuit, which was filed against 43 betting companies, asks for BR300 million in compensation and an urgent court order to force platforms to improve consumer warnings. Officials argue that vague taglines such as “play responsibly” do not meet legal standards and do little to protect vulnerable users.

Instead, the legal team is pushing for more direct alerts—full-screen or pop-up messages lasting at least ten seconds. Warnings like “betting is not an investment” or “betting may cause addiction” would be required before or during gameplay, according to the complaint.

Beyond just better warnings, the lawsuit also calls for new player protection tools. These include automatic alerts for repeated high-stakes bets, especially those placed at night, temporary account freezes when harmful patterns show up, visible self-exclusion buttons, and dashboards that display real-time losses, available funds, and total time spent betting.

The Public Defender’s Office says these steps are necessary to keep platforms accountable and better inform users about gambling-related risks. They also want to redirect the BR300 million in damages to Brazil’s national public health system to fund programs for gambling prevention and addiction recovery.

The estimated figure was based on reports from the Central Bank, which noted that Brazilians were betting around BR30 billion each month in 2024. That level of volume, they say, justifies stronger safeguards.

Companies named in the suit include some of the biggest names in the industry: Bet365, Betano, Betfair, Superbet, Stake, Pixbet, Estrela Bet, and F12 Bet. These platforms now face growing legal pressure to change how they present gambling to the public—and how they protect users from the risks that come with it.
