Sportradar Stock Falls 22% as Lawsuits Target Compliance

Sportradar is facing shareholder lawsuits in the US after reports claimed the supplier worked with illegal betting operators and generated a large share of revenue from those relationships. The allegations, published by Muddy Waters and Callisto Research on April 22, pushed Sportradar’s stock down 22.6% in one trading session and increased pressure on supplier compliance controls across the betting sector.

The lawsuits were filed in the US District Court for the Southern District of New York against Sportradar Group AG and several senior executives. Investors have until July 17, 2026 to apply as lead plaintiffs in the securities fraud cases.

Court filings focus heavily on how Sportradar described its compliance processes to investors. According to the complaints, the company said it used a “four-level process” to check that operators were licensed and repeatedly presented integrity as a core part of the business.

Muddy Waters estimated that illegal operators accounted for between 20% and 40% of Sportradar’s revenue. The firm also said the supplier continued working with operators active in regulated and banned markets through direct and indirect partnerships. Callisto Research reported similar findings and said three US gambling regulators had already started reviewing the company’s activities.

The case goes beyond Sportradar. Regulators are now paying more attention to suppliers that provide betting data, odds feeds, trading systems, and integrity services to offshore operators. The focus is no longer only on who signs the contract, but also on who uses the product through reseller and white-label deals. For operators and affiliates, this also creates more risk around the suppliers they work with, especially if those suppliers are linked to unlicensed betting activity.

TGJ Take

The main issue here is not the lawsuit itself. It is the claim that a major betting data supplier may have built part of its revenue around offshore operators while publicly presenting its compliance controls as strict. Regulators have already increased pressure on operators tied to black-market betting, and suppliers are now moving into the same line of fire. For operators, this means vendor due diligence is becoming more important, especially when suppliers work across regulated and offshore markets at the same time.
