President Luiz Inácio Lula da Silva has enacted an immediate ban on online betting websites and apps in Brazil, citing public health concerns and gambling addiction. This measure, which requires Congressional approval within 120 days, significantly impacts Brazilian football. Finance Minister Dario Durigan highlighted the issue, with Brazilians reportedly spending 60 billion reais annually on online betting.

Brazilian clubs, including Flamengo and Gremio, heavily rely on betting sponsorships, estimated at 1 billion reais across the sport, with 90% of Brasileirão Serie A clubs featuring betting companies as main shirt sponsors. Clubs argue the ban could push bettors to unregulated sites and create a financial disadvantage compared to other South American leagues like Copa Libertadores and Copa Sudamericana participants, such as River Plate, Boca Juniors, Chivas, Club America, Colo-Colo, America de Cali, Atletico Nacional, Barcelona SC, and Universitario, which continue to accept betting revenue. The debate mirrors discussions in England's Premier League and Europe's Champions League, highlighting a global struggle over gambling's role in sports.
