NBA deal gives Kalshi and Polymarket access with listing oversight

The NBA named Kalshi and Polymarket its preferred prediction market exchanges on October 26, 2026, giving both official league data and NBA branding and giving the league a say over which NBA markets the exchanges can list, and the league also signed a memorandum of understanding with the CFTC.

The NBA named Kalshi and Polymarket its preferred prediction market exchanges on October 26, 2026, according to CasinoUS. The arrangement pairs access to league resources with an NBA role in determining which markets the exchanges can offer.

Data access and league involvement

Both exchanges receive official league data and access to NBA branding, according to CasinoUS. Those benefits place the two platforms within a league-designated framework for NBA prediction markets.

The arrangement also gives the NBA a say over which NBA markets Kalshi and Polymarket can list. The supplied summary does not specify how that involvement will work or identify any markets that will be permitted or excluded.

A separate regulatory agreement

The league also signed a memorandum of understanding with the CFTC, according to CasinoUS. The supplied material does not describe its terms, leaving the scope of that agreement unclear.

What it means for prediction markets

  • Official inputs: Kalshi and Polymarket gain official NBA data and branding, though the supplied summary does not explain how either will be used.
  • Listing oversight: The NBA’s involvement makes league preferences relevant to the selection of NBA markets on both exchanges.
  • Unresolved regulatory detail: The CFTC memorandum is a separate element to watch, but the available information does not establish its practical effects.
