Sportradar Sued Over Short‑Seller Claims It Supplied Black‑Market Betting Sites

Overview

• The Smale v. Sportradar Group AG securities complaint was filed in the U.S. District Court for the Southern District of New York and alleges the company hid that it did business with black‑market gambling operators.
• Short‑seller reports by Muddy Waters and Callisto accused Sportradar of supplying products to hundreds of unlicensed platforms and Callisto said it found evidence on more than 270 such sites.
• The stock plunged about 22.6% on April 22, 2026, erasing roughly $800 million in market value after the reports contradicted the company’s public statements about compliance and KYC safeguards.
• Plaintiff firms including Kessler Topaz Meltzer & Check have solicited class members and remind investors the deadline to move for lead‑plaintiff status is July 17, 2026.
• Beyond the lawsuit, published reports say regulators in North America and Europe are reviewing the matter, which could produce separate enforcement risk or require new public disclosures and compliance changes.
