US to Allow Nvidia H200 Chip Shipments to China, Trump Says

The United States will allow Nvidia's H200 processors, its second-best artificial intelligence chips, to be exported to China and collect a 25% fee on such sales, US President Donald Trump said on Monday.

The decision appears to settle a US debate about whether Nvidia and rivals should maintain their global lead in AI chips by selling to China or withhold the exports, though Beijing has told companies not to use US technology, leaving it unclear whether Trump's decision would lead to new sales.

Nvidia shares rose 2% in after-hours trading after Trump made the announcement on Truth Social, following a 3% rise during the day on a report by Semafor.

Trump said in his post that he had informed President Xi Jinping of China, where Nvidia's chips are under government scrutiny, about the move and that he "responded positively."

He said the US Commerce Department was finalizing details of the arrangement and the same approach would apply to other AI chip firms such as Advanced Micro Devices and Intel.

Trump's post said the fee to be paid to the US government was "$25%", and a White House official confirmed he meant 25%, higher than the 15% proposed in August.

"We will protect National Security, create American Jobs, and keep America’s lead in AI," Trump wrote on Truth Social. "NVIDIA’s US Customers are already moving forward with their incredible, highly advanced Blackwell chips, and soon, Rubin, neither of which are part of this deal."

Trump did not say how many H200 chips would be authorized for shipment or what conditions might apply, only that exports would occur "under conditions that allow for continued strong National Security."

Administration officials consider the move a compromise between sending Nvidia's latest Blackwell chips to China, which Trump has declined to allow, and sending China no US chips at all, which officials believe would bolster Huawei's efforts to sell AI chips in China, a person familiar with the matter said.

"Offering H200 to approved commercial customers, vetted by the Department of Commerce, strikes a thoughtful balance that is great for America," Nvidia said in a statement.

Intel declined to comment. The US Commerce Department, which oversees export controls, and AMD did not respond to requests for comment.

A White House official said that the 25% fee would be collected as an import tax from Taiwan, where the chips are made, to the United States, where the chips will undergo a security review by US officials before being exported to China.

FEARS OF CHIPS STRENGTHENING CHINA'S MILITARY

China hawks in Washington are concerned that selling more advanced AI chips to China could help Beijing supercharge its military, fears that had first prompted limits on such exports by the Biden administration.

The Trump administration had been considering greenlighting the sale, sources told Reuters last month. Trump said last week he met with Nvidia CEO Jensen Huang and that the executive was aware of where he stood on export controls.

"It’s a terrible mistake to trade off national security for advantages in trade," said Eric Hirschhorn, who was a senior Commerce Department official during the Obama administration. "It cuts against the consistent policies of Democratic and Republican administrations alike not to assist China’s military modernization."

According to a report released on Sunday by the non-partisan think tank, the Institute for Progress (IFP), the H200 would be almost six times as powerful as the H20, the most advanced AI semiconductor that can legally be exported to China, after the Trump administration reversed its short-lived ban on such sales this year.

The Blackwell chip now in use by US AI firms is about 1.5 times faster than H200 chips for training AI systems, the IFP said, and five times faster for inferencing work where AI models are put to use. Nvidia's own research has suggested Blackwell chips are 10 times faster than H200 chips for some tasks.

Several Democratic US senators in a statement described Trump's decision as a "colossal economic and national security failure" that would be a boon to China's industry and military.

Republican Representative John Moolenaar, who chairs the House China Select Committee, said in a statement to Reuters that China would use the chips to strengthen its military capabilities and surveillance.

"Nvidia should be under no illusions - China will rip off its technology, mass-produce it themselves and seek to end Nvidia as a competitor," he said.

CHINA EYES POTENTIAL SECURITY RISKS

The approval, however, comes as China is strengthening its resolve to wean the country off its reliance on Nvidia's chips. China's cyberspace regulator in July also accused Nvidia's H20 chips of potentially carrying backdoor security risks, an allegation Nvidia has denied.

In recent months, Beijing has cautioned Chinese tech companies against buying chips that Nvidia downgraded to sell to the Chinese market, which are the H20, RTX 6000D and L20, two sources said.

"Chinese firms want H200s, but the Chinese state is driven by paranoia and pride," said Craig Singleton, a senior fellow at the Washington think tank Foundation for Defense of Democracies. "Washington may approve the chips, but Beijing still has to let them in."

The H200 change of stance comes the same day that Trump's Justice Department announced it had cracked a China-linked chip smuggling ring that in late 2024 and early 2025 exported and attempted to export at least $160 million worth of controlled Nvidia H100 and H200 chips.

Chris McGuire, an expert on technology and national security who served at the US State Department until this summer, said Chinese firms would likely still buy H200s, given that the chip "is better than every chip the Chinese can make."

China's domestic AI chip companies now include tech giant Huawei Technologies, which in September released a three-year product roadmap, as well as smaller players such as Cambricon and Moore Threads.

China's SSE STAR Chip Index and the CSI Semiconductor Industry Index both dropped more than 1% at market open on Tuesday but soon recovered most of the losses.

OpenAI Starts Testing Ads in ChatGPT

OpenAI has begun placing ads in the basic versions of its ChatGPT chatbot, a bet that users will not mind the interruptions as the company seeks revenue as its costs soar.

"The test will be for logged-in adult users on the Free and Go subscription tiers" in the United States, OpenAI said Monday. The Go subscription costs $8 in the United States.

Only a small percentage of its nearly one billion users pay for its premium subscription services, which will remain ad-free.

"Ads do not influence the answers ChatGPT gives you, and we keep your conversations with ChatGPT private from advertisers," the company said.

Since ChatGPT's launch in 2022, OpenAI's valuation has soared to $500 billion in funding rounds -- higher than any other private company. Some analysts expect it could go public with a trillion-dollar valuation.

But the ChatGPT maker burns through cash at a furious rate, mostly on the powerful computing required to deliver its services.

Its chief executive Sam Altman had long expressed his dislike for advertising, citing concerns that it could create distrust about ChatGPT's content.

His about-face garnered a jab from its rival Anthropic over the weekend, which made its advertising debut at the Super Bowl championship with commercials saying its Claude chatbot would stay ad-free.

Comparing social media platforms to casinos and addictive drugs, lawyer Mark Lanier delivered opening statements Monday in a landmark trial in Los Angeles that seeks to hold Instagram owner Meta and Google's YouTube responsible for harms to children who use their products.

Instagram's parent company Meta and Google's YouTube face claims that their platforms addict children through deliberate design choices that keep kids glued to their screens. TikTok and Snap, which were originally named in the lawsuit, settled for undisclosed sums.

Jurors got their first glimpse into what will be a lengthy trial characterized by dueling narratives from the plaintiffs and the two remaining defendants.

Meta lawyer Paul Schmidt spoke of the disagreement within the scientific community over social media addiction, with some researchers believing it doesn’t exist, or that addiction is not the most appropriate way to describe heavy social media use.

‘Addicting the brains of children’

Lanier, the plaintiff's lawyer, delivered lively first remarks where he said the case will be as “easy as ABC” — which stands for “addicting the brains of children.” He said Meta and Google, “two of the richest corporations in history,” have “engineered addiction in children’s brains.”

He presented jurors with a slew of internal emails, documents and studies conducted by Meta and YouTube, as well as YouTube’s parent company, Google. He emphasized the findings of a study Meta conducted called “Project Myst” in which they surveyed 1,000 teens and their parents about their social media use.

The two major findings, Lanier said, were that Meta knew children who experienced “adverse events” like trauma and stress were particularly vulnerable for addiction; and that parental supervision and controls made little impact.

He also highlighted internal Google documents that likened some company products to a casino, and internal communication between Meta employees in which one person said Instagram is “like a drug” and they are “basically pushers.”

At the core of the Los Angeles case is a 20-year-old identified only by the initials “KGM,” whose case could determine how thousands of other, similar lawsuits against social media companies will play out. She and two other plaintiffs have been selected for bellwether trials — essentially test cases for both sides to see how their arguments play out before a jury.

Plaintiff grew up using YouTube, Instagram

KGM made a brief appearance after a break during Lanier’s statement and she will return to testify later in the trial. Lanier spent time describing KGM's childhood, focusing particularly on what her personality was like before she began using social media.

She started using YouTube at age 6 and Instagram at age 9, Lanier said. Before she graduated elementary school, she had posted 284 videos on YouTube.

The outcome of the trial could have profound effects on the companies' businesses and how they will handle children using their platforms.

Lanier said the companies’ lawyers will “try to blame the little girl and her parents for the trap they built,” referencing the plaintiff. She was a minor when she said she became addicted to social media, which she claims had a detrimental impact on her mental health.

Lanier said that despite the public position of Meta and YouTube being that they work to protect children, their internal documents show an entirely different position, with explicit references to young children being listed as their target audiences.

The attorney also drew comparisons between the social media companies and tobacco firms, citing internal communication between Meta employees who were concerned about the company’s lack of proactive action about the potential harm their platforms can have on children and teens.

“For a teenager, social validation is survival,” Lanier said. The defendants “engineered a feature that caters to a minor’s craving for social validation,” he added, speaking about “like” buttons and similar features.

Meta pushes back

In his opening statement representing Meta, Schmidt said the core question in the case is whether the platforms were a substantial factor in KGM’s mental health struggles. He spent much of his time going through the plaintiff’s health records, emphasizing that she had experienced many difficult circumstances in her childhood, including emotional abuse, body image issues and bullying.

Schmidt presented a clip from a video deposition from one of KGM‘s mental health providers, Dr. Thomas Suberman, who said social media was “not the through-line of what I recall being her main issues,” adding that her struggles seemed to largely stem from interpersonal conflicts and relationships.

He painted a picture — with KGM’s own text messages and testimony pointing to a volatile home life — of a particularly troubled relationship with her mother.

Schmidt acknowledged that many mental health professionals do believe social media addiction can exist, but said three of KGM’s providers — all of whom believe in the form of addiction — have never diagnosed her with it, or treated her for it.

Schmidt stressed to the jurors that the case is not about whether social media is a good thing or whether teens spend too much time on their phones or whether the jurors like or dislike Meta, but whether social media was a substantial factor in KGM’s mental health struggles.

A reckoning for social media and youth harms

A slew of trials beginning this year seek to hold social media companies responsible for harming children's mental well-being. Executives, including Meta CEO Mark Zuckerberg, are expected to testify at the Los Angeles trial, which will last six to eight weeks.

Experts have drawn similarities to the Big Tobacco trials that led to a 1998 settlement requiring cigarette companies to pay billions in health care costs and restrict marketing targeting minors.

A separate trial in New Mexico, meanwhile, also kicked off with opening statements on Monday. In that trial, Meta is accused of failing to protect young users from sexual exploitation, following an undercover online investigation. Attorney General Raúl Torrez in late 2023 sued Meta and Zuckerberg, who was later dropped from the suit.

A federal bellwether trial beginning in June in Oakland, California, will be the first to represent school districts that have sued social media platforms over harms to children.

In addition, more than 40 state attorneys general have filed lawsuits against Meta, claiming it is harming young people and contributing to the youth mental health crisis by deliberately designing features on Instagram and Facebook that addict children to its platforms. The majority of cases filed their lawsuits in federal court, but some sued in their respective states.

TikTok also faces similar lawsuits in more than a dozen states.

Asking AI about medical symptoms does not help patients make better decisions about their health than other methods, such as a standard internet search, according to a new study published in Nature Medicine.

The authors said the study was important as people were increasingly turning to AI and chatbots for advice on their health, but without evidence that this was necessarily the best and safest approach.

Researchers led by the University of Oxford’s Internet Institute worked alongside a group of doctors to draw up 10 different medical scenarios, ranging from a common cold to a life-threatening hemorrhage causing bleeding on the brain.

When tested without human participants, three large-language models – Open AI's Chat GPT-4o, ‌Meta's Llama ‌3 and Cohere's Command R+ – identified the conditions in ‌94.9% ⁠of cases, ‌and chose the correct course of action, like calling an ambulance or going to the doctor, in an average of 56.3% of cases. The companies did not respond to requests for comment.

'HUGE GAP' BETWEEN AI'S POTENTIAL AND ACTUAL PERFORMANCE

The researchers then recruited 1,298 participants in Britain to either use AI, or their usual resources like an internet search, or their experience, or the National Health Service website to ⁠investigate the symptoms and decide their next step.

When the participants did this, relevant conditions were identified in ‌less than 34.5% of cases, and the right ‍course of action was given in ‍less than 44.2%, no better than the control group using more traditional ‍tools.

Adam Mahdi, co-author of the paper and associate professor at Oxford, said the study showed the “huge gap” between the potential of AI and the pitfalls when it was used by people.

“The knowledge may be in those bots; however, this knowledge doesn’t always translate when interacting with humans,” he said, meaning that more work was needed to identify why this was happening.

HUMANS OFTEN GIVING INCOMPLETE INFORMATION

The ⁠team studied around 30 of the interactions in detail, and concluded that often humans were providing incomplete or wrong information, but the LLMs were also sometimes generating misleading or incorrect responses.

For example, one patient reporting the symptoms of a subarachnoid hemorrhage – a life-threatening condition causing bleeding on the brain – was correctly told by AI to go to hospital after describing a stiff neck, light sensitivity and the "worst headache ever". The other described the same symptoms but a "terrible" headache, and was told to lie down in a darkened room.

The team now plans a similar study in different countries and languages, and over time, to test if that impacts AI’s performance.

The ‌study was supported by the data company Prolific, the German non-profit Dieter Schwarz Stiftung, and the UK and US governments.
