China Says Nvidia Violated Antitrust Law During Madrid Trade Talks

Beijing escalates pressure with fresh probes into U.S. chip policies to gain negotiating leverage.

Overview

  • China’s market regulator said a preliminary investigation found Nvidia breached anti-monopoly rules tied to conditions on its 2020 Mellanox acquisition and opened a further probe without detailing the violation.
  • Nvidia shares fell about 2%–3% in premarket trading after the announcement, and the company did not immediately comment; potential penalties under China’s antitrust law can reach up to 10% of prior-year sales.
  • The move lands as Treasury Secretary Scott Bessent meets Vice Premier He Lifeng in Madrid, with semiconductors and TikTok on the agenda for talks running through Sept. 17.
  • Separately, the Commerce Ministry launched an anti-discrimination review of U.S. chip measures and an anti-dumping case into certain U.S. analog ICs such as interface and gate-driver chips used widely in industry.
  • The dumping probe could last about a year and targets products commonly made by Texas Instruments, Analog Devices and ON Semiconductor, following Washington’s addition of 23 China-based entities to a U.S. trade blacklist.
