A billion-dollar sports betting startup, Stake.com, is now under federal investigation for allegedly evading U.S. gambling laws by routing payments through cryptocurrency, according to a leaked Department of Justice memo verified by forensic auditors. The platform, which has partnered with major UFC and soccer stars, claims to operate only in unregulated markets, but internal documents suggest a secret "stake" in American users via shell companies. Independent investigators have confirmed the documents are authentic, yet the company denies wrongdoing, sparking a global debate on crypto gambling oversight.
