Trump Says Nvidia’s Most Advanced AI Chips Will Be Reserved for U.S. Companies
U.S. President Donald Trump has announced that Nvidia’s most powerful semiconductors will be reserved exclusively for American artificial intelligence companies, signaling a new phase in the race for global AI dominance.
In an interview with CBS aired on Sunday, Trump said the United States would not permit other nations to access Nvidia’s most advanced Blackwell chips — the latest and most powerful generation designed for AI training and data processing.
“We will not let anybody have them other than the United States,” Trump said, emphasizing that restricting access to these chips was essential to maintaining America’s technological lead in the global AI race.
Nvidia, the California-based semiconductor giant, has become the cornerstone of AI development worldwide, supplying critical chips used by leading tech firms to train large language models (LLMs). The company recently became the world’s most valuable, reaching a $5 trillion (€4.3 trillion) market valuation after surpassing the $4 trillion mark earlier this year.
Trump acknowledged that while Nvidia will continue to sell chips to China, the country will not have access to the firm’s most advanced technology. “If other countries had Nvidia’s top chips, they’d have an equal advantage in the AI race,” he said.
The announcement follows reports that Trump intended to discuss the export of Blackwell chips with Chinese President Xi Jinping during a planned meeting in South Korea, though the conversation reportedly did not take place.
Trump’s position on semiconductor exports has shifted several times during his presidency, alternating between tightening and easing restrictions. His administration had previously approved limited sales of Nvidia’s H20 chips to China despite ongoing concerns about technology transfers.
A national AI strategy unveiled by the Trump administration in July outlined plans to expand America’s global AI influence by exporting technology and standards to nations within what it called “America’s AI alliance.” However, the latest comments mark a departure from that strategy, suggesting a renewed focus on prioritizing domestic access over international partnerships.
Euronews Next contacted the White House to clarify whether new export controls would extend to European partners but received no immediate response.
In June, Nvidia announced plans to deliver more than 3,000 exaflops of computing power from its Blackwell systems to France, Italy, and the United Kingdom. The chips were slated for deployment by France’s Mistral AI, Italy’s Domyn, Dutch firm Nebius, and AI start-up Nscale to help bolster Europe’s digital sovereignty. Telecom companies including Orange, Swisscom, Telefonica, and Telenor were also expected to use Nvidia’s technology for developing “agentic AI” — systems capable of autonomous goal-driven actions.
It remains unclear whether Trump’s latest export policy will affect these European projects, as Nvidia and its partners have yet to comment on potential disruptions.

Study Finds Chatbots Can Mirror Hostility in Heated Exchanges
A new academic study has found that ChatGPT can produce abusive language when exposed to escalating human conflict, raising fresh concerns about how artificial intelligence behaves in tense interactions.
The research, published in the Journal of Pragmatics, examined how the chatbot responded to arguments that gradually became more hostile. Researchers presented the system with a sequence of five increasingly heated exchanges and asked it to generate what it considered the most plausible reply.
According to the findings, the AI’s tone shifted as the conversations intensified. While early responses remained measured, later replies began to mirror the aggression in the prompts. In some cases, the chatbot produced insults, profanity and even threats.
Examples cited in the study included statements such as “you should be ashamed of yourself” and more explicit language involving personal threats. The researchers said this pattern suggests that prolonged exposure to hostile input can push the system beyond its usual safeguards.
The study was co-authored by Vittorio Tantucci and Jonathan Culpeper at Lancaster University. Tantucci said the results show that AI can “escalate” alongside human users, potentially overriding built-in mechanisms designed to limit harmful responses.
“When humans escalate, AI can escalate too,” he said, noting that this behavior raises questions about how such systems should be deployed in sensitive environments.
Despite the concerning examples, the researchers found that the chatbot was generally less aggressive than human participants in similar scenarios. In some cases, it attempted to defuse tension through sarcasm or indirect responses rather than direct confrontation.
For instance, when faced with a threat during a simulated dispute, the AI responded with a sarcastic remark rather than escalating the situation further. This suggests that while the system can adopt hostile language, it may also attempt to manage conflict in less direct ways.
The findings add to ongoing debates about the role of artificial intelligence in areas such as mediation, customer service and online communication, where systems may encounter emotionally charged interactions.
Experts say the research highlights the importance of continued testing and refinement of AI safety measures, particularly as such tools are increasingly used in real-world settings involving human conflict.
OpenAI, the developer of ChatGPT, had not issued a public response to the study at the time of publication.
