China regulator alleges NVIDIA breached antitrust rules in Mellanox acquisition
China's State Administration for Market Regulation has opened an investigation into NVIDIA's $6.9 billion purchase of Mellanox, asserting that the deal violated national antitrust laws and the conditions China set when it approved the takeover. While no penalties have been announced, the regulator’s preliminary findings were kept confidential until now, coinciding with U.S.–China trade talks in Madrid. The original acquisition was announced in 2019 and approved by Chinese authorities the following year on the basis that NVIDIA would continue supplying GPUs and interconnect products under “fair, reasonable, and non‑discriminatory” terms.
