NBA commissioner seeks prediction market data access to protect game integrity
NBA Commissioner Adam Silver said Friday that the league wants access to prediction market data to help detect potential game manipulation. Silver told CNBC that prediction markets raise the same integrity issues as sports betting for professional leagues. His comments come as regulated prediction market platforms including Kalshi and Polymarket expand into sports event contracts. Separately, Blockchain.com has filed for CFTC licenses as a Designated Contract Market and Futures Commission Merchant.
Silver's stance gives regulated platforms a lever to win league partnerships that offshore rivals cannot replicate. Kalshi and Polymarket need league cooperation to build trust with traders and regulators wrestling over whether event contracts are gambling. Data-sharing agreements could blunt state attacks by showing CFTC-registered venues actively police integrity.
The NBA joins the NFL in demanding a seat at the table, but its ask is collaborative where the league demanded Supreme Court intervention. Platforms that strike these deals first gain a commercial argument in state courtrooms. The cost is real-time data flows leagues have never received before. Polymarket and Kalshi must deliver without exposing proprietary trader positions. A leaked data term sheet becomes instant ammunition for state attorneys general framing these contracts as unregulated gambling.
