NBA pairs Kalshi and Polymarket deals with trading integrity safeguards
NBC Sports reports the NBA agreements give Kalshi and Polymarket official NBA data from Sportradar and rights to use league intellectual property, while limiting which NBA markets can be offered. The deals bar league and team personnel from trading NBA contracts and require sharing information on suspicious trading, alongside a memorandum of understanding between the NBA and the CFTC.
The NBA has designated Kalshi and Polymarket as its Preferred Prediction Market Exchanges, according to NBC Sports. The agreements combine access to official league data and intellectual property with restrictions on NBA-related markets and trading by league insiders.
Data access comes with market limits

Restrictions and information sharing
