Sportradar’s share price falls after reports claim it had links to hundreds of illegal gambling sites

• Firm insists it works only with licensed operators

• Sportradar has deals with Fifa, Uefa, MLB and NBA

The betting and data company Sportradar has relationships with hundreds of illegal gambling operators including several that appear to operate in Iran and Russian-occupied Crimea, a new report alleges.

A study compiled by the financial analysts Callisto Research claims to have identified more than 270 unlicensed betting companies offering a variety of services including sports betting, virtual gaming and crypto casinos that purport to be products of Sportradar, whose branding and tools are visible on many of their websites. Callisto Research is an activist research firm that has disclosed short selling Sportradar stock after releasing its report.
