Dutch chip equipment maker ASML says it is not selling its chipmaking machines in Europe, warning that the region risks falling behind the US, China and India in semiconductors. The remarks are drawing attention to Europe's limited role in advanced chip manufacturing despite hosting ASML itself, and are fueling debate about industrial policy and investment in the region.

A former Pentagon official said the United States needs to control China's access to advanced semiconductor technology, in comments carried by CNBC. The remarks feed into an ongoing debate in Washington over export controls on cutting-edge chips and chipmaking equipment, which US officials view as critical to maintaining a military and technological edge over Beijing.

Nvidia has added $150 billion to its share repurchase authorization, the largest buyback expansion in its history. The move signals the chipmaker's confidence in continued cash flow from the AI boom and its commitment to returning capital to shareholders, and it is drawing attention across finance and tech circles as markets weigh Nvidia's valuation.

Nvidia has expanded its stock buyback authorization by $150 billion, described as the largest addition ever to a share repurchase program. The announcement signals the chipmaker's confidence in its continued cash generation from the AI boom, and adds to the tens of billions it has already spent repurchasing its own shares.

China may permit its major technology companies to purchase new Nvidia chips, according to a report by the Digital Watch Observatory. If confirmed, the move would reopen a significant market for the US chipmaker, whose most advanced products have faced restrictions amid US-China trade tensions. The report did not specify which companies would qualify or which chip models would be covered.

Vanguard, the smaller affiliate of Taiwan Semiconductor Manufacturing Co, is considering building a second chipmaking plant in Singapore through one of its ventures. The plan is aimed at meeting growing demand for semiconductors. The news is drawing attention in Singapore's business circles, where chip manufacturing investment is closely watched for its economic impact.

AMD has agreed to acquire World Labs in a deal valued at $8.2 billion, according to a Wall Street Journal report. The acquisition would be one of the chipmaker's largest, underscoring its push to expand beyond traditional processors into AI-related technologies. Details on timing and regulatory review were not immediately available.

ASML, the Dutch maker of advanced lithography equipment, has said it currently sells no chipmaking machines to customers in Europe, an executive stated. The remark highlights how Europe's chip production relies onfabs elsewhere, as the company's machines are bought mainly by manufacturers in Asia and the United States, raising questions about Europe's semiconductor ambitions.

Nvidia has authorized a stock buyback worth roughly $150 billion, one of the largest repurchase programs ever announced. For existing shareholders, the move signals management's confidence in future cash flows and can lift earnings per share by reducing share count. For potential investors, it raises the question of whether Nvidia sees its own stock as the best use of capital, a debate now playing out across markets and financial media.

Samsung has committed $1 billion to an AI infrastructure company backed by private equity firm KKR and chipmaker Nvidia, according to the Wall Street Journal. The investment underscores how major technology companies and investors are pouring capital into data centers and computing capacity needed to support the rapid growth of artificial intelligence.

Reports indicate China is considering relaxing restrictions on NVIDIA's AI chips, a potential shift in its stance on foreign semiconductors amid the ongoing US-China technology standoff. Any easing would affect Chinese companies seeking high-end AI hardware and could reshape the competitive landscape for global chipmakers.

AMD is acquiring World Labs, the AI startup founded by Stanford professor and AI pioneer Fei-Fei Li, in a deal valued at $8.2 billion. The move marks one of AMD's biggest bets on spatial intelligence and world-model AI technology, intensifying competition with Nvidia and other chip and AI giants racing to secure leading-edge AI research talent.

Nvidia has announced an open-source security system designed to prevent autonomous AI agents from acting beyond human control. The tool is aimed at keeping agentic AI systems within defined boundaries as companies increasingly deploy them for real-world tasks. The move positions Nvidia both as a leading AI chipmaker and as a voice on AI safety, drawing attention from developers and security watchers.

Researchers are applying semiconductor chipmaking techniques to build improved electric vehicle batteries, according to a report by SciTechDaily. The approach adapts lithography-based manufacturing methods from the chip industry to battery production, potentially improving battery performance. Details on which institutions are involved and the specific results have not been widely reported, but the cross-industry idea is drawing attention in technology and energy circles.

Nvidia, the chipmaker led by chief executive Jensen Huang, has announced a new platform focused on the safety of AI agents. The product is aimed at ensuring autonomous AI systems behave reliably and securely as companies increasingly deploy them in real-world operations. Details on pricing and availability were not included in the initial announcement.

Nvidia could gain permission to sell more of its chips in China, with reports pointing to CEO Jensen Huang's growing influence over President Trump shaping US export policy. The potential shift would ease restrictions on the chipmaker's access to the Chinese market, a major revenue source, and is drawing attention given the strategic importance of semiconductors in US-China trade tensions.

Nvidia chief executive Jensen Huang has dismissed warnings from Anthropic that artificial intelligence could pose catastrophic risks, saying there is a '0% chance' AI destroys the world by 2030. His comments put him directly at odds with leading AI lab executives pushing for stronger safety precautions. The remarks are drawing attention given Nvidia's central role in supplying the chips powering the AI boom, and critics may see a commercial interest in his optimism.

Europe is pushing to become a serious player in artificial intelligence, but its plans depend heavily on foreign-controlled supply chains for semiconductors and other critical components. The continent lacks domestic chip manufacturing capacity at the scale needed for AI development, leaving it reliant on suppliers in the US and Asia. Commentators question whether Europe can build genuine tech sovereignty without securing its own hardware foundations.

Nvidia has approved the biggest share buyback ever seen in the stock market, according to Business Insider. The move signals the chipmaker's confidence in its long-term outlook despite its already enormous valuation, and comes as the company sits at the centre of the global AI boom. Investors and analysts are weighing what the unprecedented capital return means for the broader tech sector.

Nvidia has introduced a new open-source tool designed to improve the security of artificial intelligence systems. The announcement positions the chipmaker as a player in AI safety tooling, alongside its dominant role in AI hardware. Details on the tool's specific capabilities and reception from developers remain limited, but the move aligns with growing industry attention on protecting AI models from misuse and attacks.

Nvidia has announced a set of AI security tools aimed at preventing breaches involving autonomous AI agents. The announcement, covered by Yahoo Finance Canada, positions the chipmaker to address growing concerns that AI agents acting on users' behalf could be exploited or hijacked by attackers.

The Trump administration is moving to redirect unallocated CHIPS Act funds while relying on tariff threats rather than subsidies to push chipmaking onshore. TSMC retained its $6.6 billion federal grant, but pressure from tariff threats led it to raise its total US investment pledge from $65 billion to more than $165 billion. Commentators note this shifts reshoring costs onto private capital, though tariffs are seen as a far slower route to building semiconductor capacity than direct subsidies.
