Nvidia claps back against Chinese accusations its H20 chips pose a security risk

Chip giant Nvidia pushed back Sunday in response to allegations from Chinese state media that its H20 artificial intelligence chips are a national security risk for China.
Earlier in the day, Reuters reported Yuyuan Tantian, an account affiliated with Chinese state broadcaster CCTV, said in an article published on WeChat that the Nvidia H20 chips are not technologically advanced or environmentally friendly.
“When a type of chip is neither environmentally friendly, nor advanced, nor safe, as consumers, we certainly have the option not to buy it,” the Yuyuan Tantian article reportedly said, adding that the article said chips could achieve functions including “remote shutdown” through a hardware “backdoor.”
In response, a Nvidia spokesperson told CNBC that “cybersecurity is critically important to us. NVIDIA does not have ‘backdoors’ in our chips that would give anyone a remote way to access or control them.”
Nvidia on Tuesday similarly rejected Chinese accusations that its AI chips include a hardware function that could remotely deactivate the chips, also known as a “kill switch.”
Tensions between the U.S. and China on semiconductor export controls have escalated in recent weeks, even after Nvidia resumed sales of its H20 chip to China. Chinese state media has framed the H20 chip as inferior and dangerous compared to Nvidia’s other chips, while the company has defended its chips.
The company’s resumption of its H20 shipments reversed a previous ban on H20 sales that was placed in April by the Trump administration. Nvidia’s H20 chips — a less-advanced semiconductor compared to its flagship H100 and B100 chips, for example — were developed by Nvidia for the Chinese market after initial export restrictions on advanced AI chips in late 2023.
U.S. export controls on some Nvidia chips are rooted in national security concerns that Beijing could use the more advanced chips to gain an advantage broadly in AI, as well as in its military applications.

Chinese officials, meanwhile, are pushing for the U.S. to ease export controls on high-bandwidth memory chips as part of a trade deal before a possible summit between U.S. President Donald Trump and Chinese President Xi Jinping, the Financial Times reported on Sunday, citing people familiar with the matter.
Nvidia CEO Jensen Huang has supported Trump’s policies while also lobbying for export licenses for the H20 AI chip. Huang has said he wants Nvidia to ship more advanced chips to China, underscoring his outspoken stance that Nvidia’s chips becoming the global standard for AI computing is ultimately better for the U.S. to retain market dominance and influence over global AI development.
China is among Nvidia’s largest markets. Nvidia took a $4.5 billion writedown on its unsold H20 inventory in May and has warned that its topline guidance for the July quarter would have been higher by $8 billion without the chip export restrictions.
Nvidia shares were up 1% to close at $182.70 on Friday and are up 36% this year.

CoreWeave shares fell about 6% in extended trading on Tuesday even as the provider of artificial intelligence infrastructure beat estimates for second-quarter revenue
Here’s how the company did in comparison with LSEG consensus:
- Earnings per share: Loss of 21 cents
- Revenue: $1.21 billion vs. $1.08 billion expected
Revenue more than tripled from $395.4 million a year earlier, CoreWeave said in a statement. The company registered a $290.5 million net loss, compared with a $323 million loss in second quarter of 2024. CoreWeave’s earnings per share figure wasn’t immediately comparable with estimates from LSEG.
CoreWeave’s operating margin shrank to 2% from 20% a year ago due primarily to $145 million in stock-based compensation costs. This is CoreWeave’s second quarter of full financial results as a public company following its IPO in March.
CoreWeave pointed to an expansion in business with OpenAI, a major client and investor. Also during the quarter, CoreWeave acquired Weights and Biases, a startup with software for monitoring AI models, for $1.4 billion.
In May, management touted 420% revenue growth, alongside widening losses and nearly $9 billion in debt. The stock still doubled anyway over the course of the next month.
CoreWeave shares became available on Nasdaq at the end of the first quarter, after the company sold 37.5 shares at $40 each, yielding $1.5 billion in proceeds. As of Tuesday’s close, the stock was trading at $148.75 for a market cap of over $72 billion.
A CoreWeave data center project with up to 250 megawatts of capacity is set to be delivered in 2026, the company said in the statement.
Executives will discuss the results and issue guidance on a conference call starting at 5 p.m. ET.

The Trump administration is still working out the details of its 15% export tax on Nvidia and AMD and could bring deals of this kind to more companies, the White House’s Karoline Leavitt said Tuesday.
“Right now it stands with these two companies. Perhaps it could expand in the future to other companies,” said Leavitt, the White House’s spokesperson.
“The legality of it, the mechanics of it, is still being ironed out by the Department of Commerce, and I would defer you to them for any further details on how it will actually be implemented,” she continued.
President Donald Trump confirmed on Monday that he had negotiated a deal with Nvidia in which the U.S. government approves export licenses for the China-specific H20 AI chip in exchange for a 15% cut of revenue. Advanced Micro Devices also got licenses approved in exchange for a proportion of its China sales, the White House confirmed.
“I said, ‘If I’m going to do that, I want you to pay us as a country something, because I’m giving you a release,'” Trump said Monday.
“We follow rules the U.S. government sets for our participation in worldwide markets,” Nvidia said in a statement this week.
Trump said the export licenses for AMD and Nvidia were a done deal. But lawyers and experts who follow trade have warned that Trump’s deal may be complicated because of existing laws that regulate how the government can charge fees for export licenses.
The Commerce Department didn’t immediately return a request for comment.
The H20 is Nvidia’s Chinese-specific chip that is slowed down on purpose to comply with U.S. export relations. It’s related to the H100 and H200 chips that are used in the U.S., and was introduced after the Biden administration implemented export controls on artificial intelligence chips in 2023.
Earlier this year, Nvidia said that it was on track to sell more than $8 billion worth of H20 chips in a single quarter before the Trump administration in April said that it would require a license to export the chip.
Trump signaled in July that he was likely to approve export licenses for the chip after Nvidia CEO Jensen Huang visited the White House.
The U.S. regulates AI chips like those made by Nvidia for national security reasons, saying that they could be used by the Chinese government to leapfrog U.S. capabilities in AI, or they could be used by the Chinese military or linked groups.
The Chinese government has been encouraging local companies in recent weeks to avoid using Nvidia’s H20 chips for any government or national security-related work, Bloomberg reported on Tuesday.
