NBA Signs Kalshi and Polymarket Deals as Prediction Markets Gain Another Major League

The National Basketball Association is getting into the prediction market business, even as states try to push the industry out. The league named Kalshi and Polymarket its Preferred Prediction Market Exchanges on Monday, giving both platforms access to NBA intellectual property, promotional opportunities and official data. In return, the agreements restrict permissible markets, prohibit NBA personnel from trading league-related contracts, and require cooperation on suspicious activity. The NBA also signed an information-sharing agreement with the Commodity Futures Trading Commission (CFTC) and expanded its existing DraftKings relationship to include prediction markets and nationwide promotion. Financial terms were not disclosed.
