Two operators alone – Kalshi and Polymarket – topped the combined $1 billion mark in NFL trading activity over the first six days of Week 1, according to numerous measures this week. During the period, Kalshi recorded NFL volume of $983.4 million, according to DeFi Rate, earning the pole position by a large margin. Mahomes and the Kansas City Chiefs thrashed the Denver Broncos 31-10 on Monday Night Football, capping the largest week for prediction markets ever.
Even before the primetime matchup in Kansas City, it became abundantly clear that the industry would shatter previous marks for weekly activity. The AFC West showdown bolstered the already robust totals. Overall, volume for the week hit a record $15.9 billion, according to Bank of America, up 16% from a week earlier.
The pure-play prediction market-operators, Polymarket and Kalshi, emerged from Week 1 as the clear winners. On one hand, Kalshi’s market share lead narrowed over its competitors, falling to 82% for the week ended 13 September, down from 86% a week earlier.

Some factions within the government, especially the Ministry of Finance, are resisting more drastic measures. The Ministry of Finance, responsible for regulating sports betting and online gaming, understands the sector’s importance to the economy. Finance Minister Dario Durigan’s difficulty lies in convincing Lula that a well-regulated activity is important for public finances. Lula has said, in line with critics of the sector, that if it were up to him, he would end betting in Brazil.
The president’s critical view of betting is on par with other candidates. Studies by the Workers’ Party (PT) indicate that three out of four Brazilians are against betting establishments. This is the president’s justification against the sector.
What the president didn’t address is the tax revenue from betting.

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.
Commenting on his election, Macorin expressed his honour at joining the IAGR board and contributing Brazil’s experience to the association’s international work.
