The U.S. Department of Commerce announced Tuesday that it plans to prevent the sale of more advanced artificial intelligence chips to China in the coming weeks.
The U.S. government says the new rules are intended to close loopholes that popped up after last year’s restrictions on AI chip exports went into effect.
Shares of chip stocks took a leg lower in Tuesday morning trading on the news. Nvidia was down about 5% while Broadcom and Marvell slipped about 2%. Shares of AMD fell more than 3%; Intel fell about 1.5%.
Those earlier restrictions banned the sale of the Nvidia H100, which is the processor of choice for AI firms in the U.S. such as OpenAI. Instead, Chinese companies were able to buy a slightly slowed-down version called the H800 or A800 that complies with U.S. restrictions, primarily by slowing down an on-device connection speed, called an interconnect.
The new rules will ban those chips as well, senior administration officials said in a briefing with reporters.
The restrictions could also affect chips sold by Intel and AMD. Other rules will likely hamper the sale and export to China of semiconductor manufacturing equipment from companies such as Applied Materials, Lam and KLA.
The restrictions cut off a big and growing market for AI semiconductors, and could raise concerns that the Chinese government will retaliate economically against U.S. firms doing business in the country.
Nvidia seems to have anticipated the restrictions, and said in August that they would not have an immediate material effect on earnings, but might hurt over the long term.
“”We comply with all applicable regulations while working to provide products that support thousands of applications across many different industries,” an Nvidia spokesperson told CNBC. “Given the demand worldwide for our products, we don’t expect a near-term meaningful impact on our financial results.”
The goal of the U.S. restrictions is to prevent Chinese access to advanced semiconductors that could fuel breakthroughs in artificial intelligence, especially with military uses, U.S. Commerce Secretary Gina Raimondo said on a call with reporters. They’re not intended to hurt Chinese economic growth, U.S. officials said.
“The updates are specifically designed to control access to computing power, which will significantly slow the PRC’s development of next-generation frontier model, and could be leveraged in ways that threaten the U.S. and our allies, especially because they could be used for military uses and modernization,” Raimondo said.
Senior administration officials say the U.S. will simply restrict the export of data center chips if they exceed a performance threshold set last October, or exceed a new performance density threshold benchmark measured in flops per square millimeter.
Companies that want to export AI chips to China or other embargoed regions will have to notify the U.S. government.
Senior administration officials also said they plan to expand the list of semiconductor manufacturing equipment subject to U.S. restrictions.
Chips for consumer products, like game consoles or smartphones, will not be subject to the export controls, although companies may have to tell the Commerce Department about their orders if the chips are fast enough.
The U.S. government is also closing loopholes dealing with how to ship chips to companies that are headquartered in China or other embargoed regions such as Macao, to prevent a loophole where a foreign subsidiary buys chips and then ships them into China.
Raimondo said that the new restrictions will only affect a small fraction of chip exports to China.
“The fact is China, even after the update of this rule, will import hundreds of billions of dollars of semiconductors from the United States,” Raimondo said.
The rules will be available for public notice for 30 days, then will go into effect, U.S. officials said.

Chinese tech giant Xiaomi saw its shares fall over 5% on Monday, following reports that the doors of one of its electric vehicles failed to open after a fiery crash in China that left one person dead.
The stock slid as much as 8.7% in Hong Kong, marking its steepest drop since April, before paring losses after images and video of a burning Xiaomi SU7 sedan in Chengdu circulated on Chinese social media.
Video and eyewitness accounts showed bystanders trying but failing to open the doors of the burning car to rescue an occupant. Personnel at the scene eventually used a fire extinguisher to put out the blaze, local reports said.
Chengdu police said the crash occurred after the SU7 collided with another sedan, killing a 31-year-old male driver who was suspected of driving under the influence of alcohol.

Xiaomi shares
Xiaomi, which manufactures consumer electronics, software and electric vehicles, did not immediately respond to CNBC’s request for comment.
The latest incident follows a fatal SU7 crash earlier this year that raised questions about the vehicle’s smart driving features and sent Xiaomi’s shares tumbling.
The crash could also intensify scrutiny on electronic door handles, a design popularized by Tesla and now common in modern EVs.
Unlike mechanical models, electronic door handles rely on sensors and electricity and may fail during a fire or power outage.
China is considering a ban on such electric door handles to address safety risks linked to the feature, state-backed media reported in late September.
Meanwhile, the U.S. National Highway Traffic Safety Administration has launched an investigation into about 174,000 Tesla Model Y vehicles after reports of door handle failures.

The Dutch government has taken control of Nexperia, a Chinese-owned semiconductor maker based in the Netherlands, in an extraordinary move to ensure a sufficient supply of its chips remains available in Europe amid rising global trade tensions.
Nexperia, a subsidiary of China’s Wingtech Technology, specializes in the high-volume production of chips used in automotive, consumer electronics and other industries, making it vital for maintaining Europe’s technological supply chains.
On Sunday evening, the Dutch Minister of Economic Affairs revealed that it had invoked the “Goods Availability Act” on the company in September in order “to prevent a situation in which the goods produced by Nexperia (finished and semi-finished products) would become unavailable in an emergency.”
Following the announcement from the Hague, Wingtech plunged its maximum daily limit of 10% on the Shanghai Stock Exchange.
The Goods Availability Act allows the Hague to intervene in private companies to ensure the availability of critical goods in preparation for emergency situations, and its use comes amid escalations in the U.S.-China trade war.
The government statement said the “highly exceptional” move had been made after the ministry had observed “recent and acute signals of serious governance shortcomings and actions” within Nexperia.
“These signals posed a threat to the continuity and safeguarding on Dutch and European soil of crucial technological knowledge and capabilities. Losing these capabilities could pose a risk to Dutch and European economic security,” it said, identifying automotives as particularly vulnerable.
Governance changes
In a corporate filing dated Oct.13, lodged with the Shanghai Stock Exchange, Wingtech confirmed Nexperia was under temporary external management and had been asked to suspend changes to the company’s assets, business or personnel for up to a year, according to a Google translation.
Wingtech chairman Zhang Xuezheng had been immediately suspended from his roles as executive director of Nexperia Holdings and non-executive director of Nexperia after the ministerial order, according to the filing.
The filing added that Nexperia’s daily operations will continue, with the impact of the measures not yet quantifiable.
“The Dutch government’s decision to freeze Nexperia’s global operations under the pretext of ‘national security’ constitutes excessive intervention driven by geopolitical bias, rather than a fact-based risk assessment,” Wingtech said in a deleted WeChat post, which was archived and translated by Chinese policy blog Pekingnology.
It added that since it acquired Nexperia in 2019, Wingtech “has strictly abided by the laws and regulations of all jurisdictions where it operates, maintaining transparent operations and sound governance,” and employs “thousands of local staff” through R&D and manufacturing sites in the Netherlands, Germany and Britain.
A spokesperson from Nexperia told CNBC that the company had no further comments, but that it “complies with all existing laws and regulations, export controls and sanctions regimes,” and remained in regular contact with relevant authorities.
The Netherlands’ move comes after Beijing tightened its restrictions on the export of rare earth elements and magnets Thursday, which could impact Europe’s automotive industry.
The move could also further strain trade relations between China and the Netherlands, following years of restrictions on Dutch company ASML’s exports of advanced semiconductor manufacturing equipment to China.
In 2023, the Netherlands had also investigated Nexperia’s proposed acquisition of chip firm startup Nowi, though the deal was later approved.

Navan, a developer of corporate travel and expense software, expects its market cap to be as high as $6.5 billion in its IPO, according to an updated regulatory filing on Friday.
The company said it anticipates selling shares at $24 to $26 each. Its valuation in that range would be about $3 billion less than where private investors valued Navan in 2022, when the company announced a $300 million funding round.
CoreWeave, Circle and Figma have led a resurgence in tech IPOs in 2025 after a drought that lasted about three years. Navan filed its original prospectus on Sept. 19, with plans to trade on the Nasdaq under the ticker symbol “NAVN.”
Last week, the U.S. government entered a shutdown that has substantially reduced operations inside of agencies including the SEC. In August, the agency said its electronic filing system, EDGAR, “is operated pursuant to a contract and thus will remain fully functional as long as funding for the contractor remains available through permitted means.”
Cerebras, which makes artificial intelligence chips, withdrew its registration for an IPO days after the shutdown began.
Navan CEO Ariel Cohen and technology chief Ilan Twig started the company under the name TripActions in 2015. It’s based in Palo Alto, California, and had around 3,400 employees at the end of July.
For the July quarter, Navan recorded a $38.6 million net loss on $172 million in revenue, which was up about 29% year over year. Competitors include Expensify, Oracle and SAP. Expensify stock closed at $1.64on Friday, down from its $27 IPO price in 2021.
Navan ranked 39th on CNBC’s 2025 Disruptor 50 list, after also appearing in 2024.
