The warning shot landed in markets before it landed in politics. China’s competition regulator said a preliminary probe found Nvidia in violation of the country’s anti-monopoly law, triggering a dip in the chipmaker’s shares. The investigation focuses on Nvidia’s 2020 acquisition of Israeli networking company Mellanox, a deal approved at the time with conditions that Beijing now believes were breached.
• Nvidia accused of breaching China’s anti-monopoly law
• Probe tied to 2020 Mellanox acquisition
• Nvidia shares slipped in premarket trading
While regulators did not specify the alleged violation, the announcement adds fresh strain to the company’s already fraught presence in China. Nvidia has tried to balance U.S. export restrictions with its massive demand in the Chinese AI market, creating modified products like the H20 chip. But even those efforts have stumbled, with shipments blocked earlier this year despite compliance tweaks.
• Details of alleged breach remain unclear
• Nvidia has struggled under U.S. export controls
• China previously blocked shipment of modified H20 chip
The timing of the announcement is critical. Trade officials from Washington and Beijing are meeting in Madrid this week, with semiconductors once again at the center of disputes. Just days ago, China launched two separate probes into U.S. chip imports, one targeting alleged dumping and the other scrutinizing trade discrimination. The Nvidia case risks deepening tensions as both sides spar over control of critical technologies.
• Nvidia probe coincides with U.S.-China trade talks in Spain
• China investigating dumping and discrimination in chips
• Semiconductor disputes intensify between the two powers
For Nvidia, the stakes go beyond compliance. Chief executive Jensen Huang has argued that cutting off access to China risks ceding a market he values at $50 billion to domestic rivals like Huawei. His lobbying recently secured a deal with Washington allowing resumed sales to China, though at the cost of surrendering 15 percent of that revenue to the U.S. government.
• Nvidia CEO warns of losing China’s $50B AI market
• U.S. allowed resumed sales with revenue-sharing condition
• Domestic Chinese firms positioned to fill gaps if Nvidia retreats
Beijing’s preliminary finding is only the first step, but it signals a willingness to use antitrust law as leverage in its broader technological contest with Washington. As the probe continues, Nvidia faces the dual challenge of navigating regulatory pressure in China while staying compliant with restrictions at home. The outcome could redefine not just its China strategy but the balance of power in the global AI race.
• China uses antitrust law as strategic tool
• Nvidia caught between U.S. and Chinese regulations
• Case may shape global competition in AI chips
