Nvidia Faces Antitrust Probe in China Over Merger/ Newslooks/ WASHINGTON/ J. Mansour/ Morning Edition/ Chinese regulators allege Nvidia violated antitrust rules related to its 2020 acquisition of Mellanox Technologies. A preliminary probe found noncompliance with approval conditions, intensifying tensions as U.S.–China trade talks continue. The move follows broader efforts by Beijing to counter U.S. dominance in the semiconductor sector.

Nvidia Antitrust Probe in China Quick Looks:
- Regulatory Claim: China says Nvidia broke antitrust conditions from 2020.
- Mellanox Deal: Focus is on $6.9B Mellanox Technologies acquisition.
- Ongoing Investigation: Regulators plan to continue probing Nvidia’s actions.
- Trade Context: Announcement aligns with U.S.–China trade talks in Spain.
- Chip War Escalation: Part of China’s wider scrutiny of U.S. chip firms.
- New Probes: Beijing launched anti-dumping and discrimination inquiries targeting U.S. chip companies.
- Tech Power Struggle: Nvidia central to ongoing U.S.–China tech rivalry.
- Previous Restrictions: Nvidia already faces U.S. export bans on chip tech.
- Government Talks: U.S. Treasury Secretary meets Chinese VP in Madrid this week.
- Trade War Pauses: Both sides agreed to repeated tariff ceasefires.
Deep Look: Nvidia Under Antitrust Investigation in China Amid Trade Talks
LONDON (AP) — China has launched a formal accusation against Nvidia, alleging the U.S.-based chip giant violated its antitrust laws by failing to meet conditions set during the approval of its $6.9 billion acquisition of Mellanox Technologies in 2020. The announcement, made Monday by the State Administration for Market Regulation (SAMR), signals Beijing’s renewed push to exert control over foreign technology giants operating within its borders.
The preliminary findings, shared in a brief statement, did not detail any penalties but confirmed that Chinese authorities plan to conduct a “further investigation.” This could open the door to financial penalties, business restrictions, or even forced structural changes to Nvidia’s operations in China—though none of those steps have yet been confirmed.
Merger Conditions Under Scrutiny
Nvidia’s acquisition of Israeli-based Mellanox Technologies was completed in 2020 after a lengthy review process, including conditional approval from Chinese regulators. While the specific conditions were never publicly disclosed in detail, they typically relate to maintaining fair competition, technology licensing, or market access assurances. Chinese regulators now claim Nvidia did not adhere to those terms, leading to the current inquiry.
Nvidia has yet to respond to the allegation, remaining silent as the story develops.
Timing Tied to Trade Talks
This announcement arrives at a diplomatically delicate moment, as high-level trade negotiations between the U.S. and China take place in Madrid. U.S. Treasury Secretary Scott Bessent is holding meetings with Chinese Vice Premier He Lifeng between Sunday and Wednesday to discuss tariffs, trade imbalances, and national security concerns—particularly those involving U.S. control over tech firms like TikTok.
It’s the fourth round of these negotiations, with previous talks held in London, Geneva, and Stockholm. So far, both governments have managed to delay further economic escalation by implementing a series of 90-day suspensions on new reciprocal tariffs.
Still, the Nvidia antitrust action could shift the tone of the current talks, particularly given the company’s symbolic importance in the global chip race.
Broader Moves Against U.S. Tech
Nvidia is not the only U.S. chipmaker under pressure. Over the weekend, China’s Ministry of Commerce announced two additional investigations that further intensify the tech rivalry.
First, an anti-dumping probe was launched into analog IC chips imported from the United States. These chips, commonly used in everyday electronics, are often produced by firms such as Texas Instruments and ON Semiconductor.
Second, a separate antidiscrimination investigation was announced, targeting perceived U.S. bias against Chinese semiconductor firms. This inquiry focuses on restrictions and policy decisions from Washington that China claims unfairly limit its tech sector’s global competitiveness.
Both investigations reflect Beijing’s efforts to push back against Washington’s attempts to isolate China’s high-tech industry.
Nvidia: A Symbol of U.S. Tech Dominance
Santa Clara-based Nvidia has become a linchpin in the U.S.–China technological cold war. Once known primarily for its gaming graphics processors, Nvidia has grown into the world’s most valuable semiconductor firm, with cutting-edge chips used in AI, data centers, and defense applications.
Because of its strategic role, Nvidia has already been affected by a series of export bans and restrictions imposed by both President Joe Biden and his predecessor, Donald Trump. These limitations aim to prevent China from acquiring advanced AI and military-related chip technology.
In response, China has sought to boost its own chip development, even as it continues to depend on companies like Nvidia for cutting-edge components.
What Comes Next?
While the one-sentence announcement from SAMR is light on specifics, it marks the beginning of what could be a prolonged legal and regulatory battle. Should China escalate the matter, Nvidia could face:
- Fines or financial penalties.
- Operational restrictions within the Chinese market.
- Pressure to restructure deals or unwind aspects of the Mellanox acquisition.
For the U.S., the move adds yet another variable to an already fragile trade relationship. As both countries balance economic cooperation with technological competition, Nvidia’s case could serve as a litmus test for future actions against American tech firms operating in China.
