Sportradar Group AG is facing a securities class action lawsuit on behalf of investors who purchased Class A ordinary shares between November 7, 2024 and April 21, 2026. The suit follows a 22% single-day share collapse on April 22, 2026, triggered by reports from Muddy Waters Research and Callisto Research accusing the company of misleading investors about the legality of its business model. Muddy Waters estimated that illegal operators deliver approximately 20-40% of total revenues, while Callisto found evidence that over 270 platforms—more than a third of the 800 Sportradar claims to serve—are using its products while operating illegally. The market reaction wiped out over $800 million of Sportradar’s market capitalization in one day. Law firm Hagens Berman is investigating the claims and has set a lead plaintiff deadline of July 17, 2026.
