Genius Sports lands both Polymarket and Kalshi for official sports data
Genius Sports signed official data, integrity, and streaming deals with Polymarket on August 4 and Kalshi on August 5. The agreements give both CFTC-registered platforms access to live sports data, including Genius Sports' full soccer portfolio for Kalshi. Genius Sports CEO Mark Locke said the partnerships demonstrate that official data is vital for prediction market operators. The sports data company's shares rose on the announcements.
Genius Sports just became the standard data layer for every major regulated prediction market. Both Polymarket and Kalshi now run on identical official feeds, so neither can claim data access as an edge. Rivalry shifts to execution speed and user experience.
Smaller venues without Genius Sports contracts face higher costs sourcing delayed or unofficial data. The company is now positioned to set terms with any remaining platform that wants league-certified markets. A third platform signing similar terms would cement Genius Sports as the gatekeeper for regulated sports prediction markets in the United States.
