Polymarket Enters 20-Plus Sports Leagues With Sportsradar Partnership

Sports data provider Sportradar has partnered with prediction market company Polymarket to extend its services to over 20 sports leagues and competitions. The deal covers approximately 300,000 matches per year and includes global leagues such as the Bundesliga, Euroleague Basketball, Chinese Basketball Association, National Basketball League, Tennis Grand Slams, and UTR Pro events.

This partnership comes on the heels of Sportradar's existing relationship with Polymarket, which includes sports organizations like Major League Baseball, National Hockey League, UFC, and the ATP tour.

Sportsradar CEO Carsten Koerl expressed excitement about the new collaboration, stating that accurate real-time data, premium live content, and a robust integrity framework are crucial for these markets to price efficiently, settle reliably, and retain participants' confidence. The expanded partnership offers Polymarket fast, accurate data and live odds for pre-game and in-play markets, as well as integrity services to detect and allow users to report suspicious behavior.

While sports wagering constitutes the majority of transaction volume on U.S. prediction markets, legality remains a contentious issue. The MLB and NHL have agreed to share data, but the National Basketball Association has not. Regulatory oversight is also a point of contention, with the Commodity Futures Trading Commission indicating it is responsible, though some states argue Polymarket and Kalshi are offering illegal sports betting and evading state licensing and tax rules.

The regulatory landscape remains uncertain, with federal registration providing platforms neither nationwide access nor protection from state gambling enforcement.
