The National Basketball Association disclosed on Monday that it has entered into multi‑year agreements with prediction‑market platforms Kalshi and Polymarket, naming them the league’s preferred exchanges for NBA‑related markets.

The deals include provisions that restrict the types of markets that can be offered, give the NBA approval rights over market design, and require information‑sharing on suspicious trading activity.

A memorandum of understanding with the U.S. Commodity Futures Trading Commission (CFTC) accompanies the agreements, reflecting a shared commitment to regulatory oversight and integrity protections for NBA‑related prediction markets.

Kalshi and Polymarket will be permitted to use NBA branding, access league statistical data via Sportradar, and market themselves as the “Preferred Prediction Market Exchange of the NBA.”

The NBA’s head of media distribution and partnerships, Scott Kaufman‑Ross, said regulated prediction markets provide better transparency and monitoring than unregulated alternatives, helping protect the integrity of games.

The league also announced that its existing sportsbook partners, such as DraftKings, will be allowed to offer prediction‑market products under the same integrity framework.

Restrictions similar to those already imposed on sportsbooks—such as bans on wagering on first‑stat outcomes or player participation under certain conditions—are expected to apply to the new prediction‑market offerings.

While the agreements’ financial terms were not disclosed, the NBA confirmed they span multiple years, and several NBA players have previously promoted the platforms, though some, like Victor Wembanyama, have publicly declined endorsement.
