Major League Baseball

The National Basketball Association has entered an information sharing arrangement with the Commodity Futures Trading Commission and named Kalshi and Polymarket as preferred exchanges. The move places pro basketball alongside baseball and hockey while the National Football League continues to oppose the federal path for sports event contracts.

Polymarket is mounting a broad U.S. rehabilitation effort after a four-year ban, using a CFTC-supervised mobile app, sports partnerships and social media marketing to rebuild trust. The campaign follows past regulatory scrutiny, a settlement with the CFTC and investigations that were later dropped without charges.
