China says Nvidia violated anti-monopoly law

China’s market regulator on Monday said that Nvidia violated the country’s anti-monopoly law, according to a preliminary probe, adding that Beijing would continue its investigation into the U.S. chip giant.

Shares of Nvidia were down around 2% in premarket trading.

Late last year, China’s State Administration for Market Regulation (SAMR) opened an investigation into Nvidia in relation to the acquisition of Mellanox and some agreements made during the acquisition.

Nvidia acquired the Israeli technology company that creates network solutions for data centers and servers in 2020, in a deal that was approved by China at the time with certain conditions.

In a preliminary investigation, the SAMR said Nvidia had violated China’s anti-monopoly laws in relation to that acquisition and its conditions.
