Brazil has taken decisive action against Polymarket and Kalshi by blocking access to these platforms and prohibiting derivatives linked to sports events, virtual gaming, political outcomes, and other non-economic benchmarks. According to NS3.AI, Finance Minister Dario Durigan stated that these platforms contravene betting regulations sanctioned by Congress and are neither legal nor regulated within the country. Banco Central do Brasil emphasized that this measure aims to safeguard investors and uphold market integrity.
