Brazil has introduced stricter controls on sports betting advertisements as the 2026 FIFA World Cup drives a significant increase in betting activity across the country. The surge in betting has raised concerns about gambling-related harm, with the percentage of Brazilians placing bets tripling from 11% before the tournament to around 35% by late June, according to a study by fintech company Klavi based on a sample of 1.2 million people.
This rapid growth in betting participation coincides with a rise in gambling addiction cases, which have more than doubled in the past five years, according to Brazil’s health ministry. The increased exposure to betting ads, including live endorsements and real-time odds promotions during broadcasts, has drawn criticism from politicians and public figures alike.
Brazil legalized sports betting in 2018, but the initial lack of regulation led to a flood of advertising and sponsorships. In response, the government introduced new regulations in 2023 to better control the market. Now, amid World Cup fever, authorities have intensified enforcement efforts. The Finance Ministry recently requested explanations from two media outlets and four betting operators regarding content that may have breached advertising laws. It also ordered the immediate suspension of any ads found to violate current regulations.
Brazil has become the third-largest sports betting market globally, trailing only the US and the UK, according to a 2023 report by data analysis company Comscore. However, a 2025 study by the non-profit Institute of Studies for Health Policies estimates that gambling costs Brazilian society approximately 38.8 billion reais ($7 billion) annually, contributing to increased rates of depression and suicide.
Major sporting events like the World Cup can heighten players’ emotional investment, which may amplify gambling-related stress and harm. Michael Marcos, a 22-year-old transport inspector from Alagoas, shared how betting on matches increased his anxiety. He adopted cautious betting strategies, such as wagering only on teams he believes are very likely to win, and plans to stop betting after the tournament ends.
Concerns also extend to younger and vulnerable audiences. Platforms such as Caze9TV, which holds exclusive rights to broadcast all World Cup games in Brazil, have faced scrutiny for blending betting promotions with live commentary. This practice risks exposing minors and other at-risk groups to gambling advertising outside traditional commercial breaks.
We are witnessing a humanitarian tragedy unfolding in Brazil,
said Senator Eduardo Gire3o during a Senate hearing addressing the issue. Musicians like Gilberto Gil and Caetano Veloso have also joined campaigns calling for stricter gambling laws to protect vulnerable populations.
Players and bettors in Brazil should be aware that these regulatory changes may affect the availability and presentation of betting advertisements during the World Cup. The increased scrutiny aims to reduce indiscriminate exposure and enhance player protection, especially for minors and those susceptible to gambling harm.
