Sportradar and Polymarket expand prediction market deal to more than 20 leagues
Sportradar and Polymarket have expanded their partnership to cover more than 20 leagues and competitions. The deal adds exclusive streaming rights for the Bundesliga and Euroleague Basketball, plus official data for tennis Grand Slams. It builds on an existing relationship that previously included the ATP Tour, Major League Baseball, the National Hockey League, and Major League Soccer. Sportradar is the data and streaming provider; Polymarket is a CFTC-regulated prediction market platform.
Data is now the primary battleground among regulated prediction markets. Sportradar's expanded deal gives Polymarket exclusive streaming and official data across more than 20 leagues. Kalshi and Novig must match that coverage or cede the live-trading edge to Polymarket. The Genius Sports contracts with both Polymarket and Kalshi already erased data exclusivity as a moat.
This Sportradar expansion tips the scale back toward Polymarket on breadth and real-time access. Rivals face a choice: pay up for comparable feeds, or accept slower settlement and narrower menus that drive users to the platform with the fuller slate. The next platform that lands a comparable multi-league streaming and data package will set the new baseline. Until then, Polymarket owns the widest certified sports catalogue among CFTC-regulated venues.
