NBA signs prediction market deals with Kalshi and Polymarket despite scandals

The NBA has announced 'preferred' prediction market partnerships with Kalshi and Polymarket, a memorandum with the US CFTC, and an expanded DraftKings deal. The markets can use official league data, with limits on permissible markets and sharing of suspicious trades. The move comes as the league faces gambling scandals involving Jontay Porter, Terry Rozier and Chauncey Billups.
