When Australia hosts its first-ever regular season NFL game, an estimated 10,000 US fans are expected to attend the matchup at the Melbourne Cricket Ground following an exhausting trip that features one of the world’s longest flight paths.
The historic showdown between the Los Angeles Rams and the San Francisco 49ers will take place at a venue located 7,971 miles from Levi’s Stadium, home of the last meeting between the NFC West rivals. Both teams are based in California, a fertile ground for prediction markets given a sports betting ban in a state with more than 39 million residents. But the Americans in attendance for Thursday night’s matchup (Friday in Melbourne) will not be able to live-trade from their seats.
That is because trading on prediction markets is illegal down under, according to the Australian Securities and Investment Commission, the nation’s regulator on financial services. Last month, in perhaps the ASIC’s strongest warnings yet against the asset class, the commission reiterated that prediction markets are not licensed as financial markets to operate in Australia. Through the guidance, the regulator urged consumers to exercise caution before partaking in certain investments on offshore platforms which have not obtained licensing nationwide.

“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.

Still, Kalshi had a nine-fold lead over Polymarket, its next closest rival. Polymarket, meanwhile, led the group with 762,000 app downloads, edging Kalshi, DraftKings and FanDuel in the category. The downloads represented a 13,509% weekly increase and 25% of total category downloads, Polymarket wrote in a statement.
Across the market, operators delivered high double-digit gains compared with Labor Day weekend, which featured a full slate of college football games but no NFL contests. Two operators, DraftKings and Underdog each saw triple-digit growth, delivering weekly increases of 125% and 119%, respectively. Three others, Polymarket, Crypto.com and Novig, saw gains of at least 30%, led by Polymarket with a weekly increase of 46%.
One interesting nugget surrounds weekend figures at Kalshi, where volume on Sunday only surpassed prior daily activity by $34 million, BofA data shows. Typically, Sunday volume for the quarter dwarfs that of College Football Saturdays due to the voracious demand for NFL offerings. BofA analyst Shaun Kelley attributes the irregularity to the possibility that Kalshi is “over indexing” on college sports.
