The National Basketball Association (NBA) has named Kalshi and Polymarket as its preferred prediction market exchanges, entering into agreements that commit the league and the platforms to cooperate with U.S. regulators on oversight. Prediction markets let traders buy and sell contracts tied to the outcomes of real-world events, including sports results. The move comes as the prediction-market industry faces growing scrutiny over insider trading and the integrity of sports-related contracts.

According to the league, the partnerships will restrict the types of markets that can be offered, prohibit league and team personnel from trading contracts tied to NBA events, and require information sharing related to suspicious trading and investigations. The prohibition on personnel trading speaks directly to the insider-trading concerns that have followed the sector's expansion into sports-event contracts.

The NBA has also signed a memorandum of understanding with the Commodity Futures Trading Commission (CFTC), the federal agency that regulates derivatives, to improve cooperation and information sharing on prediction-market integrity. The agreement follows similar arrangements between the regulator and Major League Baseball and the National Hockey League, formalizing direct information-sharing channels between the leagues and the regulator at a time when scrutiny of the sector is growing.

Under the commercial agreements, Kalshi and Polymarket will receive rights to use NBA intellectual property, promotional opportunities across U.S. media channels, and official league data supplied through Sportradar, which will be used to operate and settle authorized markets.

The NBA has further expanded its existing agreement with sports betting operator DraftKings to cover prediction markets and nationwide promotion, and the league plans to extend similar arrangements to other partners.

The move comes as U.S. authorities investigate alleged gambling-related misconduct involving professional basketball and debate whether prediction markets should fall primarily under federal derivatives regulation or state gambling laws. The CFTC maintains that it oversees these markets, while several states have challenged the agency's position.

The regulatory environment remains contested. Major League Baseball has warned that gambling rules apply to prediction markets, and New York has sued crypto exchanges Coinbase and Gemini over their prediction-market offerings, with state officials declaring that "gambling by another name is still gambling."

The sector has also drawn attention over market-integrity concerns. An analysis by BitcoinKE argued that prediction markets have an insider trading problem that needs fixing, while blockchain analytics firm Chainalysis reported that the FIFA World Cup generated $20 billion in prediction-market volume.

The partnerships give the NBA greater oversight of how participating platforms offer contracts tied to its games, while providing the exchanges with official data and commercial access to the league. However, the agreements do not resolve the broader legal dispute over prediction-market jurisdiction in the United States. How that dispute is settled — between the CFTC's federal oversight claim and challenges from several states — will determine the legal framework under which sports-related prediction markets operate.
