China Hits Nvidia with Antitrust Probe, Deepening US Tech Cold War
Beijing uses an antitrust probe against Nvidia as a strategic weapon in the escalating U.S.-China tech cold war.
September 15, 2025

In a significant escalation of the ongoing technology rivalry between Washington and Beijing, Chinese regulators have accused U.S. semiconductor giant Nvidia of violating antitrust laws.[1] The accusation, announced by China's State Administration for Market Regulation (SAMR), stems from a preliminary investigation into commitments the company made during its acquisition of Israeli networking hardware firm Mellanox Technologies in 2020.[2] This move places the world's most valuable chipmaker at the center of a geopolitical struggle, creating further uncertainty for the global artificial intelligence industry and happening concurrently with high-stakes trade negotiations between U.S. and Chinese officials in Madrid.[3][4]
The heart of the issue lies in the conditional approval SAMR granted for Nvidia's $6.9 billion takeover of Mellanox.[5] To secure the deal, Nvidia agreed to a set of conditions designed to ensure fair competition in the Chinese market.[6] These commitments included pledges not to bundle or tie its products, to continue supplying its graphics processing units (GPUs) and Mellanox's interconnect products to Chinese customers on fair, reasonable, and non-discriminatory (FRAND) terms, and to ensure its hardware remained compatible and interoperable with that of its competitors.[5][6] According to Chinese authorities, a probe launched in December of the previous year found that Nvidia had failed to uphold these promises.[2][7] While SAMR's public statement was brief and did not specify the exact nature of the violations, it confirmed the investigation would continue, a process that could culminate in substantial fines and new operational restrictions on the company in China.[8][9]
This antitrust probe is inextricably linked to the broader "tech cold war" between the United States and China.[2] Washington has implemented a series of stringent export controls aimed at restricting China's access to high-end semiconductor technology, which it fears could be used for military and surveillance purposes.[9][4] These controls have directly impacted Nvidia, forcing the company to halt sales of its most advanced AI chips to Chinese clients and develop less powerful, export-compliant versions like the H20 accelerator.[9][10] Consequently, some analysts believe Nvidia may be in a difficult position, caught between complying with U.S. regulations and fulfilling the commitments it made to Chinese regulators.[11] Beijing's investigation is widely viewed as a retaliatory measure and a strategic maneuver to gain leverage in the ongoing trade discussions, where access to semiconductor technology is a key point of contention.[4][12]
The implications for Nvidia and the wider AI and semiconductor industries are substantial. China remains a significant market for Nvidia, accounting for $17 billion in revenue in the last fiscal year, or about 13% of its total sales.[13][14] Under Chinese antitrust law, potential fines can range from one to ten percent of a company's annual revenue in the country, which could translate to a penalty of up to $1.7 billion for Nvidia.[13] Beyond financial penalties, the investigation could lead to operational restrictions, further complicating Nvidia's ability to do business in one of its most critical markets.[9] The news has already created ripples in the financial markets, with Nvidia's stock dipping in pre-market trading following the announcement.[9][14] For the broader tech world, this action signals deepening fragmentation of the global semiconductor supply chain and highlights the growing risks for multinational corporations navigating the U.S.-China rivalry.[4]
In conclusion, China's antitrust accusation against Nvidia marks a new chapter in the escalating global tech dispute. By targeting a key American company and linking the violation to a prior acquisition agreement, Beijing is demonstrating its willingness to use its regulatory power as a tool in its strategic competition with Washington.[4] The future of Nvidia's operations in China and the potential for further retaliatory measures from both sides will likely depend on the outcome of the ongoing trade negotiations. The final decision by China's regulators will be closely watched, as it could set a precedent for how foreign technology companies are treated and further shape the geopolitical landscape of the artificial intelligence industry for years to come.[3]
