The lawsuit, Smale v. Sportradar Group AG, currently pending in the U.S. District Court for the Southern District of New York, claims the company misrepresented the robustness of its Know-Your-Customer and regulatory compliance processes. According to the complaint, Sportradar intentionally partnered with black-market operators to bolster its revenue, directly contradicting public assurances that ethics and integrity remained central to its operations.

Scrutiny intensified on April 22, 2026, when Muddy Waters Research and Callisto Research released independent reports suggesting the company facilitated illegal betting on a global scale. Muddy Waters alleged that aiding these markets was a core business strategy rather than an oversight, while Callisto identified hundreds of platforms using Sportradar services while operating in prohibited jurisdictions. Following the release of these findings, Sportradar shares dropped 22.6%, falling from $16.84 to $13.04 in a single session. Investors seeking to serve as lead plaintiff in the class action must file their motions by July 17, 2026.
