As World Cup fever grips Brazil, scrutiny mounts over its sports betting industry

When World Cup season descends upon soccer-mad Brazil , green and yellow banners decorate restaurants, bars and apartment buildings, streets are painted with flags and soccer balls, and discussions of the beloved national team's games are ubiquitous.

But this year, another topic has taken center stage: the prevalence of ads for bets on the games, even as the country grapples with a surge in gambling which leaves some with crippling debt and has led to the number of people seeking care for addiction more than doubling in the past five years, according to Brazil's health ministry.

Since the FIFA World Cup began, the percentage of Brazilians placing bets has more than tripled, rising from 11% in May before the tournament kicked off to around 35% at the end of June, said Brazilian fintech company Klavi in a study based on a sample of 1.2 million people.

Brazil has become the third-biggest market in the world for sports betting, following the U.S. and the U.K., a report by data analysis company Comscore said in 2023.

Betting and gambling are estimated to cost Brazilian society 38.8 billion reais ($7 billion) annually and increase suicide and depression, according to a 2025 study by the non-profit Institute of Studies for Health Policies.

“We are witnessing a humanitarian tragedy unfolding in Brazil,” said Sen. Eduardo Girão during a public hearing on the problem at the Senate on Thursday. The issue has prompted musicians such as Gilberto Gil and Caetano Veloso to participate in a campaign demanding stricter laws.

Michael Marcos, a 22-year-old transport inspector from Brazil’s northeastern state of Alagoas, is among those who suffered from anxiety due to betting last year. He decided to take a six-month break, before picking the habit up again during the World Cup.

“Watching Brazil play is already an emotional experience. But if I bet 1000 reais ($200) on them, the emotion will be even greater because there’s an accompanying tension to do with whether I’m going to win or lose money,” he said.

To limit the impact on his mental health, Marcos is only betting on teams, such as France, he thinks are very likely to win. So far, he says his strategy has worked out for him. Nonetheless, he plans on stopping at the end of the tournament.

CazéTV, a streaming platform on YouTube and the only channel with rights to all 104 games in Brazil, has faced particular scrutiny.

“Betting is intended for people aged 18 and over. But when it is embedded in content (…) anyone can be exposed to it, including children, teenagers, and other vulnerable groups. The exposure becomes indiscriminate,” said Carolina Terra, a professor at the University of Sao Paulo’s communications and arts school.

Brazil’s National Consumer Secretariat, a branch of the Justice Ministry, opened an investigation into possible irregularities during CazéTV’s broadcasts of the World Cup on June 24.

Freitas said he doesn’t see it as a form of income, but as a pastime.

“No one believes they’re going to become rich playing videogames on weekends. It’s the same for betting,” he said. “The problem is thinking that you’re going to find the perfect formula and forgetting the old saying (…): the bank always wins.”
