SAN FRANCISCO, May 1, 2026 /PRNewswire/ -- Investors in Sportradar Group AG (NASDAQ: SRAD) saw the price of their shares crater 22% on April 22, 2026. The collapse was triggered by reports published by Muddy Waters Research and Callisto Research that each accused the company of misleading investors about the legality of its business model.

The developments have prompted national shareholder rights firm Hagens Berman to open an investigation into whether Sportradar's disclosures before April 22 may have violated federal securities laws.

Sportradar Group AG (SRAD) Investigation:

The investigation is focused on the propriety of Sportradar's statements about working only within the legal gambling markets.

As recently as early November 2025, Sportradar's management assured investors that, as to its data not showing up in markets it should not be ending up in, the company is "only working with licensed operators, and we have contracts which are enabling those operators only to work in the territory where they are licensed in." The company also touted its 4-level know your customer ("KYC") framework designed to monitor illegal gambling market activity and verify clients to ensure integrity in sports betting data services.

These assurances came into question on April 22, 2026, when two activist short seller firms published highly critical reports on Sportradar's business practices.

Muddy Waters Research conducted an undercover investigation, analyzed Sportradar's website code, and interviewed 15 current and former company employees to reach its conclusion that "SRAD has actively aided and abetted illegal gambling across the world's black and grey markets – not as an accident or an oversight, but as a business strategy." The firm "estimate[d] that illegal operators today deliver approximately 20-40% of total revenues[]" to Sportradar. Muddy Waters said it "identified nearly 50 companies as current or recent SRAD clients and collaborators who are operating in illegal markets."

For its part, Callisto examined hundreds of gambling platforms and reported that it found evidence that "over 270 individual platforms (more than a third of the 800 Sportradar claims to serve) are using Sportradar's products or services, or explicitly claiming to do so, while operating illegally in regulated or prohibited gambling markets." Callisto also said "[m]any of these operators have no license whatsoever[]" and "a senior former employee we spoke to estimated the exposure to unlicensed operators could be as high as 30-40% of Sportradar's revenue."

The market swiftly reacted, wiping out over $800 million of Sportradar's market capitalization in a single day.

"Given the huge market for- and growth within- online betting, and the need for effective guardrails to assure legality of such conduct, we're investigating whether, if Muddy Waters' and Callisto's conclusions are accurate, Sportradar may have misled investors about the legality of its business practices," said Reed Kathrein, the Hagens Berman partner leading the firm's investigation.
