Nvidia Antitrust Violation Finding In China Signals Rising Global Enforcement Risks

On September 15, 2025, China's State Administration for Market Regulation (SAMR) issued a preliminary finding that NVIDIA, one of the world's largest technology companies, violated China's Anti-Monopoly Law of 2008 (AML) in relation to its $6.9 billion acquisition of Mellanox Technologies (Mellanox) in 2020. SAMR had previously approved that transaction, imposing behavioral conditions to prevent NVIDIA from using Mellanox's high-performance networking products, namely InfiniBand technology, to foreclose competition with Chinese firms. The finding comes as China heightens scrutiny of foreign semiconductor companies in an escalating trade war with the United States, leaving NVIDIA caught in the middle of a multinational antitrust regulatory battle.
