The NBA announced agreements on October 26, 2026 naming Kalshi and Polymarket its preferred prediction market exchanges, according to The Tartan. The arrangements combine access to league assets with restrictions on markets and participation.
League rights and official data
Both exchanges receive rights to use NBA intellectual property, The Tartan reported. They also gain access to official NBA data supplied by Sportradar to operate and settle authorized markets.
That links the commercial agreements to market operations: the exchanges receive both permission to use league assets and an official data source for determining outcomes. The supplied summary does not identify which markets are authorized.
Restrictions and regulatory coordination
The NBA also entered a memorandum of understanding with the CFTC, according to The Tartan. Alongside that step, the exchange agreements impose limits on permissible markets and prohibit trading by league and team personnel.
The agreements also provide for information sharing during investigations into suspicious trading. The supplied summary does not detail the scope of those arrangements or the memorandum’s specific terms.
What it means for prediction markets
- Settlement data: Access to official NBA data supplied by Sportradar is a central operational feature for authorized markets on Kalshi and Polymarket.
- Market availability: Preferred-exchange status comes with limits on permissible markets; the summary does not establish which contracts will be offered.
- Integrity safeguards: Personnel trading prohibitions and investigative information sharing accompany the agreements, while the CFTC memorandum adds a separate regulatory coordination element.
