Shares of Nvidia dropped over 2% Monday following China’s announcement of an antitrust investigation into the company. The probe reportedly focuses on Nvidia's 2019 acquisition of Mellanox Technologies for nearly $7 billion, though details remain sparse. Nvidia, which generates 16% of its revenue from China, is cooperating with regulators. Nvidia shares are up 180% this year, driven by soaring AI demand that boosted its market value to $3.5 trillion.
