NBA Steps Into Prediction Markets With Kalshi and Polymarket Deals

The NBA is moving into prediction markets, lining up partnerships with two of the sector's best-known platforms, Kalshi and Polymarket. The league has also signed a memorandum of understanding with the Commodity Futures Trading Commission, the federal regulator that oversees prediction markets in the United States.

Prediction markets let users trade contracts tied to the outcomes of real-world events, with prices reflecting the crowd's view of how likely each result is. For a league whose games already draw heavy betting interest, the tie-up signals a shift from keeping that activity at arm's length toward working directly with the platforms that offer it.

The memorandum with the CFTC stands out. An agreement of this kind suggests the league wants a formal working relationship with the agency that decides how event contracts can be offered and policed, rather than relying on informal understandings. The available summary does not spell out the terms of that memorandum, so its scope, obligations and timing remain unclear.

Several questions are also still open. The announcement does not detail what the Kalshi and Polymarket arrangements involve, whether they cover data, promotion or content rights, or which products will launch first. Nor does it say how the league plans to address integrity concerns, such as limiting trading on games or individual players, which have been a central worry for sports leagues entering this space.

Fans and bettors should watch for those specifics. The key things to track are the commercial terms of each partnership and any rules or guidance the CFTC issues that would govern sports-related contracts.
