The U.S. Supreme Court has upheld a class-action lawsuit against Nvidia, accusing the company of misleading investors about its dependence on cryptocurrency sales. The case follows significant stock price drops after a decline in cryptocurrency profitability. Nvidia's argument for dismissal was rejected, leaving the appeals court ruling intact. The suit, initially filed in 2018, highlights corporate accountability and comes amid other legal challenges for Nvidia, including investigations into potential anti-monopoly violations in China.
