Brazilian officials are reviewing betting ads shown around World Cup broadcasts after data pointed to a sharp rise in betting during the tournament. CazéTV, Globo, and SBT all aired matches, while CazéTV also drew attention because presenters discussed betting options during coverage.
Good to know
The Ministry of Justice is reviewing CazéTV, Globo, and SBT over possible abusive advertising practices linked to betting ads during prime time World Cup broadcasts. CazéTV, a YouTube channel with major tournament coverage, faces extra attention because betting promotions appeared inside live presentation, not only in standard ad breaks. AP reported that Brazil National Consumer Secretariat opened an investigation into possible irregularities in CazéTV World Cup broadcasts on June 24.
The timing gives regulators a clear reason to act. A Klavi survey based on Open Finance data from the Brazilian Central Bank integration system found that 34.8% of Brazilians had placed bets since the tournament started. In May, the figure stood at 11%, so World Cup betting activity more than tripled in only a few weeks.
Klavi reviewed a sample of 1.2 million people and counted only transfers to legal betting sites. Average deposits also rose. On June 28, the average deposit per user reached R$ 272, or about $52.3, compared with R$ 188 before the tournament. The daily average has stayed above the pre World Cup level since the first matches.
June 14 produced the highest average so far at R$ 524, or about $100, one day after Brazil faced Morocco. Night activity also dominated the data. More than 60% of deposits came after 6 PM, while only 10% came in the morning, when no matches took place.
Rodrigo Machado, coordinator of the Technological Dependencies Group at the Psychiatry Outpatient Clinic of the Hospital das Clínicas, linked nighttime betting to known risk patterns.
“That’s when people aren’t under the supervision of their spouse and have less self-control,” he said.
Machado also said embarrassment in front of family and friends often leads gamblers to seek medical care.
Klavi found a heavy imbalance in spending. The top 10% of bettors by deposit volume put in 20 times more than the other 90% combined. The betting industry often calls that group high rollers, but from a public health view, such concentration can also point to harm risk.
Brazil already applies betting advertising rules that require warnings against gambling and health risk notices. The Ministry of Finance monitors betting operator conduct and can apply fines of up to R$ 2 billion, or about $380 million, for violations.
Courthouse News reported that Brazil betting regulator notified four betting operators and two media outlets over World Cup ads with possible rule breaches. The report also said CONAR, Brazil advertising self regulatory body, opened three proceedings over betting offers read aloud by presenters and commentators, then recommended suspension of those ads.
The Brazilian Institute for Responsible Gaming, known as IBJR, represents the three companies under review. The group said Brazilian law already sets strict standards and voiced support for the authorities investigation.
Other countries use tighter broadcast rules for gambling advertising. Australia bars betting ads during live sport. The United Kingdom allows them only after 9 PM. Portugal sets the line at 10:30 PM. The Netherlands and Belgium prohibit gambling ads that use public figures.
For Brazil sports betting, online betting ads, World Cup gambling, responsible gambling policy, and gambling advertising rules, the current case may become an early test of how far regulators want to go during major sports events.
