Nvidia denies presence of 'backdoors' in chips amidst China's concerns over security
Nvidia, a California-based world-leader in AI semiconductor production, has resumed sales of its H20 AI chip to China after a six-month export ban. This move, however, is fraught with significant trade tensions and security concerns.
The U.S. government, particularly under the Biden administration, imposes strict restrictions due to fears that these advanced chips could enhance China’s AI capabilities used for military purposes, censorship, and technological competition. Washington effectively restricts which chips Nvidia can export to China on national security grounds.
The Cyberspace Administration of China has asked Nvidia to explain the security risks of vulnerabilities and backdoors in its H20 chips sold to China. Beijing's top internet regulator has summoned Nvidia representatives to discuss recently discovered "serious security issues" involving the H20.
Despite these challenges, Nvidia's CEO, Jensen Huang, reaffirmed the company's commitment to serving local customers in China during a recent visit to Beijing. However, geopolitical risks remain high. China is advancing rapidly in domestic AI chip development, with local companies like Huawei and Cambricon increasing market share, expected to rise from 17% in 2023 to 55% by 2027 due to U.S. export restrictions.
Commercially, although resuming H20 exports temporarily raised Nvidia’s projected China revenue to $19.5 billion for 2026, these geopolitical risks persist. U.S. lawmakers, such as Rep. John Moolenaar, have expressed strong opposition to Nvidia resuming sales, highlighting risks that these chips could accelerate China’s AI military applications and undercut U.S. innovation.
Jost Wubbeke of the Sinolytics consultancy states that the U.S. decision to allow renewed exports of the H20 to China could be counterproductive, potentially undermining momentum behind the 910C and other domestic alternatives. This underscores the delicate balance Nvidia must maintain between lucrative market opportunities and U.S. national security concerns.

The ongoing trade tensions and political concerns are heightened as the U.S. government continues to impose restrictions on Nvidia's AI chip exports to China, due to fears of enhancing China's AI military capabilities and digital competition. Simultaneously, China's domestic AI chip market expands rapidly, with local companies like Huawei and Cambricon poised to capture a majority market share by 2027, driven by U.S. export restrictions. Despite this delicate balance, Nvidia's commitment to the Chinese market remains steady, but the geopolitical risks persist, potentially impacting the financial prospects of the company and the broader economy.
