The Swiss sports data and betting integrity provider Sportradar experienced a significant stock decline on Wednesday following the publication of critical reports from two research organizations alleging the company maintains business relationships with improperly licensed gambling operators.
Callisto Research and Muddy Waters Research both issued the reports. The firms revealed they maintained short positions in Sportradar shares, positioning themselves to gain financially from any decline in the stock’s value.
Sportradar issued a response late Wednesday through a brief four-paragraph statement, describing the reports as containing “several factual inaccuracies.”
The organization maintained that the report authors aimed to “profit from stock disruption.” Sportradar emphasized that it conducts operations “with the highest ethical standards” while adhering to all relevant laws and regulatory requirements.
The 43-page analysis from Callisto asserted that over one-third of betting operators using Sportradar’s services either lack proper licensing in regulated jurisdictions or accept wagers in territories where gambling activities are forbidden.
Research Firms Estimate Unlicensed Operators Generate Up to 40% of Company Revenue
Both research organizations calculated that operators without proper licensing could represent approximately 40% of Sportradar’s overall revenue. The company maintains a public listing on the US NASDAQ stock exchange.
Earlier in the current month, Sportradar released its annual report for 2025. The financial document revealed total yearly revenues approaching 1.29 billion euros, equivalent to over $1.5 billion.
Callisto reported discovering approximately 100 Sportradar customers presenting licenses from what the research firm characterized as a fraudulent regulatory authority based in Anjouan. This small island territory, situated between Mozambique and Madagascar, maintains a population below 300,000 residents.
The research firm additionally disclosed that it distributed its findings to gaming regulatory bodies across North America and Europe. Callisto indicated that three US regulatory agencies have initiated investigative proceedings based on the information provided.
Callisto projected that Sportradar will ultimately face a decision between abandoning revenue streams from illegal operators or risking the loss of its operating licenses in Europe and North American markets.
Muddy Waters released a comprehensive 123-page document containing separate allegations. The organization stated that its undercover investigators engaged with Sportradar personnel at ICE, a prominent gaming industry conference that took place in Barcelona during the early part of this year.
Muddy Waters Claims Sportradar Representative Suggested Connection to Questionable Operator
The undercover operatives presented themselves as representatives of a new venture seeking to establish sportsbook operations in China, Vietnam, Thailand, and Indonesia. Gambling activities remain illegal throughout all four nations.
According to the Muddy Waters account, instead of rejecting the proposal, a Sportradar sales representative proposed facilitating a connection with the Yabo Group. Muddy Waters characterized Yabo as a China-based gambling operation that allegedly employs victims of human trafficking and forced labor in its customer service operations.
“Sportradar’s CEO likes to call his company the FBI of gambling,” the Muddy Waters report stated. “The FBI does not offer to introduce informants to human traffickers at trade shows.”
Muddy Waters additionally called upon major professional sports organizations that maintain partnerships with Sportradar to investigate these matters. The firm contended these leagues are “unwittingly profiting” from the company’s alleged relationships with illegal betting platforms.
Numerous sports leagues maintain revenue-sharing arrangements with Sportradar, although the report noted most receive portions below 10%. Sportradar has also distributed equity stakes to the National Basketball Association, the National Hockey League, and Major League Baseball.
Despite maintaining a short position, Muddy Waters announced intentions to begin covering a “substantial majority — possibly all” of its holdings to safeguard investors.
Sportradar communicated to Gambling Insider that the research reports demonstrate “a fundamental misunderstanding of our business and the industry.” The company asserted it collaborates “exclusively with licensed operators” while maintaining “strict global compliance and due diligence standards.”
Sportradar delivers data feeds and live odds across more than 30 sporting categories to betting platform operators. The company additionally provides streaming services and fraud prevention solutions utilized by over 250 partners and law enforcement organizations globally.
Shares began Wednesday’s session at $16.70, declined to a low of $11.69 during mid-session trading, and concluded at $13.04 — representing a decline of approximately 22.6%. Extended-hours trading reflected an additional one-cent decrease from the closing figure.
