Scott Kaufman-Ross did not say the NBA had picked a side. He said protecting the integrity of the game was the league's top priority. The effect of what he announced on Monday is the same either way.
The NBA's designation of Kalshi and Polymarket as preferred prediction market exchanges comes bundled with something that matters more than marketing rights or promotional activations: official NBA data, flowing exclusively through Sportradar, will now power both platforms. That is not a symbolic gesture toward the new industry. It is a data moat, and it belongs to two operators.
The practical architecture of the deal rewards attention. Kalshi and Polymarket receive Sportradar's official feeds to operate and settle authorised NBA markets. DraftKings, which already held an NBA sports betting partnership, gets an expanded agreement that stretches into prediction markets and nationwide promotion. The WNBA is not included. The NFL is not in the room.
The NFL's absence is worth holding for a moment. The NBA, the NHL, and Major League Baseball have now each aligned with the prediction market framework. The NFL has filed a brief supporting New Jersey's regulator in its Supreme Court petition, arguing that sports-event contracts are gambling rather than financial instruments subject to CFTC jurisdiction. Every league that signs a Sportradar data deal with Kalshi and Polymarket makes that argument harder to sustain before a court that will notice who the industry's own participants have chosen to stand with.
The consensus read is that the NFL's legal position weakens in proportion to the number of leagues defecting from it. That is probably right. Where the consensus may be underweighting something is on the data exclusivity question. The Sportradar arrangement does not just provide settlement data — it creates a two-platform infrastructure that everyone else, including any operator the NBA later adds to its preferred list, will depend on. Sportradar has existing partnerships with both Kalshi and Polymarket already, so Monday's announcement formalised and extended something that was already partly in place. The interesting variable is what the NBA's phrase "expand its relationship with other current official sports betting partners" actually means in practice — whether that expansion includes data access or only marketing rights is not specified in what the league has put on record.
The New York Gaming Commission's parallel effort to compel Kalshi's records through a Manhattan court, and the CFTC's simultaneous suit against Utah, both belong to the same underlying dispute: who has authority over these markets. The NBA's deal does not resolve that. What it does is create a set of commercial facts on the ground — official data pipelines, IP licences, integrity frameworks — that will be difficult to unwind regardless of how the jurisdictional litigation settles.

Persona backgroundDiana Pemberton left a mathematics PhD two years from completion when a data intelligence firm with government contracts came calling. She wanted to see how the system actually worked. She spent six years finding out. In 2022 she produced an analysis that was correct in every detail. It was operationally deprioritised in September.
The NBA designated Kalshi and Polymarket as preferred prediction market exchanges with exclusive access to Sportradar's official NBA data feeds for operating and settling authorised markets. DraftKings received an expanded agreement covering prediction markets and nationwide promotion. This arrangement creates a data moat where official settlement information flows only through Sportradar to these two operators, rather than being distributed broadly across the prediction market industry.
The NBA, NHL, and Major League Baseball have each signed Sportradar data agreements with Kalshi and Polymarket for prediction markets. The WNBA and NFL remain outside these arrangements. The NFL has instead filed a Supreme Court brief supporting New Jersey's regulator, arguing that sports-event prediction contracts constitute gambling under traditional frameworks rather than financial instruments subject to CFTC jurisdiction.
The NFL's regulatory position—that sports-event contracts are gambling rather than CFTC-regulated financial instruments—weakens each time another major league signs with Kalshi and Polymarket, since courts will observe that sports leagues themselves have chosen the prediction market framework. The commercial infrastructure of official data pipelines and integrity agreements these deals create will be difficult to unwind regardless of how jurisdictional litigation ultimately resolves.
Kalshi and Polymarket now operate as the authorised prediction market exchanges for official NBA events, receiving exclusive Sportradar data feeds for market operation and settlement. Both platforms have existing Sportradar partnerships that Monday's announcement formalised and extended, establishing them as the infrastructure through which NBA prediction markets will be priced and resolved.
