Sports Entertainment Gaming Global Corp (SEGG) shares fell sharply on Wednesday, dropping 18.9% after a short-seller report from White Diamond accused the company of being essentially non-operational and of promoting a dubious partnership with Polymarket.
The White Diamond report alleges SEGG has "almost no business, no cash" and is named as a defendant in six active lawsuits. The short-seller also said the company has failed to file key regulatory reports - specifically its 2025 Form 10-K and the first quarter 2026 Form 10-Q.
White Diamond pointed to a recent surge in the stock - more than 200% - that followed a SEGG press release announcing an "exclusive partnership" with Polymarket tied to SEGG's sports.com domain. The short-seller described that announcement as likely fraudulent and questioned the substance behind the deal.
According to the report, SEGG issued at least 12 press releases during 2025 announcing business expansions or partnerships that White Diamond says never came to fruition. The short-seller further asserted that SEGG acquired the sports.com domain in early 2021 but has not developed the site nor generated revenue from it.
White Diamond inspected sports.com and described its current state as a simple landing page requesting email addresses and offering no active functionality. The site reportedly indicates it is "Launching for the World Cup 2026," with the World Cup scheduled to begin on June 11, 2026, per the report.
Raising practical concerns about the purported Polymarket arrangement, White Diamond argued that sports.com appears to have no user base and therefore would provide no clear benefit to Polymarket. The short-seller added that integrating a market platform like Polymarket into a website typically requires months of development work, and that operating a site that holds bettors' funds would involve obtaining government licenses.
The short-selling firm said it has reported SEGG to the U.S. Securities and Exchange Commission and stated publicly that it expects the Polymarket deal will not be completed before the World Cup begins.
Context and implications
Investors reacted quickly to White Diamond's assertions, driving the stock lower on the day of the report's publication. The claims in the report focus on corporate disclosures, the state of the sports.com asset, the feasibility of the announced partnership and pending litigation.
