Sportradar Group's shares fell 12% on Wednesday after short seller Muddy Waters revealed a short position and alleged the sports data provider knowingly serves illegal gambling operators. The report claims undercover interactions at ICE Barcelona showed Sportradar staff willing to pursue business with illicit operators, and estimates that such clients account for an estimated 20%-40% of revenue and an even larger share of profits.

Key Points

  • Sportradar shares fell 12% after Muddy Waters disclosed a short position and published allegations about the company's dealings with illegal gambling operators.
  • Muddy Waters reported an undercover interaction at ICE Barcelona where representatives said they wanted to target illegal markets and claimed Sportradar staff were willing to proceed.
  • The short seller estimated illegal operators account for about 20%-40% of Sportradar's revenue and a larger portion of profits, asserting the company would be unprofitable without that revenue.

Sportradar Group (NASDAQ:SRAD) experienced a marked decline in its share price, falling 12% on Wednesday after short seller Muddy Waters disclosed a short position and published allegations about the company's client base and sales conduct.

Muddy Waters said it conducted an undercover approach at the ICE Barcelona event, where representatives of the short seller informed Sportradar's sales team that they intended to target illegal markets. According to Muddy Waters, those interactions indicated that Sportradar was willing to do business with operators that the short seller described as illegal.

The short seller provided an estimate that operators it classifies as illegal account for roughly 20% to 40% of Sportradar's revenue. Muddy Waters added that these clients likely represent a disproportionately larger share of the company's profits, and asserted that without revenue tied to such gaming operators Sportradar would be unprofitable.

Muddy Waters further alleged that an Asia sales executive at Sportradar offered to introduce the undercover representatives to the Yabo Group, which Muddy Waters described as China's largest illegal operator. The short seller said this alleged introduction offer took place despite warnings about the operator's legal status.

The report noted that Callisto Research had previously disclosed a short position in Sportradar. Muddy Waters stated it reached its conclusions independently, while also saying it concurs with Callisto Research's assessment of the company.

Sportradar supplies sports betting data and integrity services to professional leagues and gambling operators around the world. The company has publicly positioned itself as a provider of integrity monitoring services intended to combat match-fixing and other threats to sporting contest integrity.

The Muddy Waters disclosure and accompanying allegations prompted the immediate market reaction reflected in Wednesday's share price decline. The claims focus on the composition of Sportradar's customer base, the conduct of sales representatives in a trade-event setting, and the financial reliance on clients Muddy Waters labels illegal.
