The National Basketball Association has named Kalshi and Polymarket its preferred prediction market exchanges. The league also signed an agreement with the Commodity Futures Trading Commission, the federal regulator of prediction markets. The NBA says the deals limit which event contracts can be featured and require information-sharing about suspicious trades. Bloomberg reports that the league will also license official data to the platforms and bars league and team personnel from trading on them. NBA head of media distribution and partnerships Scott Kaufman-Ross said protecting the integrity of the game is the league’s top priority.
