NBA names Kalshi and Polymarket preferred prediction market partners
The NBA announced Monday it is partnering with Kalshi and Polymarket as the league's preferred prediction market platforms. The agreements include trading safeguards and integrity provisions around official league data and intellectual property. The deal also expands the NBA's existing partnership with DraftKings. The partnerships mark the first time a major US professional sports league has formalized relationships with both CFTC-regulated prediction market platforms.
The NBA's preferred status gives Kalshi and Polymarket a marketing platform and credibility shield that smaller CFTC-registered rivals cannot replicate. Sponsorship by a major US sports league signals to state regulators and courts that regulated prediction markets deserve integration rather than exclusion.
For Kalshi, this arrives while its Sixth Circuit preemption challenge sits defeated and state enforcement actions multiply. The league's integrity framework may become the template other leagues require before they risk similar partnerships. If the NFL follows with its own pact, the political coalition against state-level event-contract bans gains institutional weight.
Joins the NBA's own parallel integrity deal with the CFTC and its DraftKings extension as part of a single-day repositioning that treats regulated prediction markets as partners rather than threats to competitive integrity.
