Nvidia’s shares slumped by around 2.2% in pre-market trading on Monday after China opened a probe into alleged violations of the country’s anti-monopoly rules. It was announced that Beijing’s market regulation office had commenced an investigation into the market-leading advanced chip manufacturer over its acquisition of Mellanox in 2020. China previously approved this deal on the basis that it would not lead to discriminatory treatment toward Chinese companies. The development comes amid rising trade tensions between the United States and China, with tit-for-tat moves over the last week.
