NBA Partners with Kalshi and Polymarket, Third U.S. League to Embrace Prediction Markets

The NBA has partnered with Kalshi and Polymarket, becoming the third major U.S. sports league to embrace prediction markets. The deals allow official NBA logos and data use, and the league will influence markets. New York alleges Kalshi operates illegal sports betting, and New Jersey has asked the Supreme Court to review the dispute. The NBA says its contracts address potential restrictions.
