CazéTV, a popular streaming channel, is under investigation by the Brazilian National Consumer Secretariat (Senacon) and the Ministry of Justice for alleged "misleading or abusive advertising" of sports betting platforms during its World Cup transmissions. Senacon initiated its investigation into CazéTV on June 25, just days after the Ministry of Justice began its preliminary inquiry on June 24. The investigations are focused on whether the channel's promotional strategies, which linked betting to major sporting events and offered attractive odds, violated consumer protection principles and responsible gaming guidelines. The authorities are also examining the role of narrators and commentators in incentivizing bets and promoting specific offers.

Several specific instances of alleged infractions were cited. These include an advertisement during an England vs. Ghana match, the promotion of a "second chance" offer during the Argentina vs. Austria game, and an ad during the Uruguay vs. Cape Verde match that associated Brazilian passion for football with sports betting. The Ministry of Justice specifically noted an incentive for viewers to use a QR code directing them to a betting site and campaigns that linked betting to "belonging, sports passion," and "cultural identity." The investigations aim to determine if there was adequate separation between editorial and advertising content and if the advertising complied with regulations on social responsibility, transparency, and consumer information.

In response to the scrutiny, CazéTV stated it would implement a "more conservative" advertising standard for betting promotions to maintain the channel's authentic style while adhering to regulatory frameworks. The channel has also reportedly removed and re-edited some World Cup transmission videos to adjust commercial inserts and ensure compliance. Additionally, the National Council for Self-Regulation in Advertising (Conar) recommended the suspension of three specific betting advertisements from KTO, Betnacional, and Bet365 displayed on CazéTV during the World Cup, citing concerns that these ads, presented by commentators and narrators, implied easy gains and encouraged immediate action, possibly violating self-regulation rules established in December 2023.
