NBA Opens Its Doors to Kalshi and Polymarket With Strict Rules

On October 26, 2026, the NBA named Kalshi and Polymarket as preferred prediction-market exchanges, securing direct oversight of tradable contracts. This alignment includes a move toward a CFTC data-sharing pact, which may reshape sports betting regulation and enhance market legitimacy. By partnering with these two giants, the NBA aims to influence state policies and integrate federal oversight into its ecosystem, ensuring stricter rules govern the contracts traded on these specific prediction-market platforms.
