Nvidia Hit With China Probe in Escalation of Global Tech Wars

China has opened a probe into Nvidia Corp. over suspicions that the US chipmaker broke anti-monopoly laws around a 2020 deal, taking aim at the AI heavyweight as Washington ramps up sanctions.

Nvidia’s market value has ballooned this year on demand for chips that can run artificial intelligence programs, making it one of the most valuable publicly traded companies and China’s largest corporate target in the tech trade war so far.

China had approved Nvidia’s $7 billion acquisition of Mellanox on condition that the Israeli computer networking equipment maker provide information about new products to rivals within 90 days of making them available to Nvidia.
