NBA to provide official data to Kalshi, Polymarket, expanding prediction markets

The National Basketball Association has designated Kalshi and Polymarket as preferred prediction market exchanges and signed an information-sharing agreement with the U.S. Commodity Futures Trading Commission to strengthen integrity in basketball-related markets. The NBA will provide official game data and apply safeguards against insider trading. The deal grants rights to use NBA intellectual property in the United States. The move comes as legal disputes continue over whether federal commodities rules pre-empt state gambling laws.
