NBA signs prediction market deal with Kalshi and Polymarket

The National Basketball Association has signed a deal with prediction market platforms Kalshi and Polymarket. Under the agreement, the two platforms stand out as the league's preferred prediction market partners. The platforms will gain access to official league data and brand assets.

As part of the agreement, an integrity framework will be put in place. The league will have a say over which markets are offered. The parties will share information, and the NBA will sign a memorandum of understanding with the federal regulator, the Commodity Futures Trading Commission.

Adam Barrick, Kalshi's head of sports partnerships, said the partnership with the NBA is an important milestone for the company. NBA Executive Vice President Scott Kaufman-Ross said the league had been waiting to partner with prediction markets until an appropriate regulatory system is in place.

Prediction markets have faced pushback from state and tribal regulators since they began offering sports event contracts in 2025. State officials argue the companies are trying to circumvent gambling laws. The companies counter that their products differ from traditional sports betting and are regulated solely by the CFTC. New Jersey officials have asked the Supreme Court to settle the matter.
