NBA Sets Prediction Market Framework With Kalshi, Polymarket

The NBA has named Kalshi and Polymarket as its preferred prediction market exchanges and introduced a formal integrity framework for basketball-related event contracts. The agreements give both platforms access to official league data and US marketing rights while placing limits on the markets they can offer. The league also signed a memorandum of understanding with the Commodity Futures Trading Commission covering cooperation and information sharing. NBA and team personnel are prohibited from trading NBA event contracts, while Kalshi and Polymarket must provide information connected to investigations and suspicious activity.
