On September 15, 2025, China’s State Administration for Market Regulation (SAMR) released a notice stating that, following a preliminary investigation, NVIDIA Corporation had been found to have violated the Anti-Monopoly Law of the People's Republic of China (the specific violated articles are not mentioned in the original text, but it's common to refer to the general law violation in such contexts). Legally, the SAMR has decided to carry out a more in-depth probe into the matter.

NVIDIA, founded in the United States in 1998, is mainly involved in the research, development, manufacturing, and marketing of graphics processors. Mellanox, established in Israel in 1999, specializes in the research, development, production, and sales of network interconnection products. In 2019, NVIDIA announced its acquisition of all shares of Mellanox. Once the merger was finalized, Mellanox became a wholly-owned subsidiary of NVIDIA.
