“Brazil has undergone an ambitious regulatory transformation in an extraordinarily short period, and his experience at the heart of this process will provide valuable insights to the regulators within our global community.”

Before joining the Ministry of Finance, Fabio Macorin served in Brazil’s Federal Police for 17 years. For a decade, he focused specifically on the investigation and prevention of banking and financial fraud. This experience helped shape his approach to betting regulation, particularly regarding anti-money laundering, financial monitoring, combatting the illegal market and inter-agency cooperation.

Brazil’s regulated betting market formally launched in 2025 and has since become one of the most closely watched regulatory initiatives in the global gaming and betting sector. Macorin, who also served as the SPA’s undersecretary for monitoring and enforcement, has been directly involved in initiatives to combat illegal operators, strengthen cooperation with financial institutions, telecommunications providers and other government authorities, as well as develop data-driven tools for regulatory oversight and enforcement.

Maloney leads an association that features sportsbook powerhouses such as DraftKings, FanDuel, Fanatics and Bet365.

“We welcome efforts by leagues, players and regulators to build on that work and make clear that harassment has no place in sports,” Maloney told iGB.

The NFL referenced a comparable incarnation of the platform in a letter this summer to the US Commodity Futures Trading Commission on prediction markets. The league was one of several that submitted public comments to the CFTC in regards to the agency’s proposed rules on event contracts.
