Polymarket has expanded its partnership with Swiss sports data provider Sportradar Group AG, listed on NASDAQ under the ticker SRAD, to cover more than 20 sports leagues and competitions globally. The deal will provide about 300,000 matches annually with premium data, live streaming and integrity services, expanding Polymarket’s flow of timely, resolvable sports events. Coverage includes exclusive streaming rights for Germany’s Bundesliga and Euroleague Basketball, as well as official data feeds for Tennis Grand Slams and the Chinese Basketball Association. The agreement builds on an earlier 2026 partnership covering properties including the ATP Tour, MLB, NHL, MLS and UFC. Sportradar CEO Carsten Koerl described prediction markets as a compelling adjacent growth opportunity, while Ari Borod said the expanded access would operate at unprecedented scale. Sportradar also signed a separate multiyear data and integrity-services agreement with CFTC-regulated U.S. prediction market Kalshi in June 2026. Financial terms for either deal were not disclosed. The partnerships position Sportradar across differing regulatory models as Polymarket operates on Polygon and has primarily served international users amid regulatory uncertainty in the United States, while Kalshi operates under CFTC regulation.
