This is Europe's secret weapon against Trump: it could burst his AI bubble T he unthinkable has happened. The US is Europe's adversary. The stark, profound betrayal contained in the Trump administration's national security strategy should stop any further denial and dithering in Europe's capitals.

Elon Musk could become the world's first trillionaire if he hits targets set by Tesla, under a scheme disclosed by the electric car company he runs and in which he is the largest shareholder. Tesla outlined the terms of the incentive package, unprecedented in corporate history, in a section of its latest stock market update that began: "Yes, you read that correctly." Musk, the company said, will have to increase the value of the company from just over 1tn today to 8.5tn over 10 years. If he presides over growth on that scale, the 54-year-old would receive new shares that would push his stake in the company from nearly 16% to well beyond 25%, increasing the fortunes of the world's richest man to more than 2tn. Estimates of Musk's current net worth vary but a live ranking of the world's wealthiest people on the planet, compiled by Forbes, estimates the South African-born tycoon's fortune at 430.9bn.

Chip giant Nvidia is set to release its latest earnings report – and the results could move the entire US stock market. Over the past two years, the chipmaker has risen to become the world's most valuable company, with a market capitalisation of more than 4 trillion. When Nvidia announces its earnings on Wednesday, investors will get to see how the tech giant has been faring amid the tumult of President Donald Trump's trade salvoes and concerns about whether artificial intelligence has been overhyped. Nvidia specialises in making the graphics processing units (GPUs) that power AI, including the Blackwell B200, marketed as the world's most powerful chip. The California-based company's chips have become essential to the world's largest tech companies, including Microsoft, Meta, Amazon and Alphabet, since AI exploded into the mainstream with the release of OpenAI's generative AI chatbot, ChatGPT, in November 2022.

Nvidia has recorded the biggest daily jump in market value in the history of Wall Street. The California-based chip maker on Wednesday added 330bn to its market capitalisation – blasting past the previous record it set in February with a 277bn single-day gain. Shares of Nvidia soared nearly 13 percent, buoyed by expectations that demand for its chips will remain strong after Microsoft on Tuesday announced that AI-related capital spending in the 2024 fiscal year rose 60 percent to 69bn. Nvidia's latest stock rally takes its market cap to 2.88 trillion, making it the world's third-most valuable company after Apple and Microsoft. Nvidia, whose graphics processing units (GPUs) are integral to the development of AI, briefly became the world's most valuable company in June after knocking Microsoft off the top spot with a market cap of 3.335 trillion.

Nvidia has handed back the position as the world's most valuable company to Microsoft after its share price fell by more than 3.5% on Thursday. The artificial intelligence (AI) chip giant briefly held the top spot from Tuesday, with a stock market valuation of 3.34tn ( 2.64tn). But Nvidia's shares fell to 130.78 on Thursday, sending its value down to around 3.22tn, with Microsoft reclaiming the title as it held steady at more than 3.3tn. Nvidia's rise has been fuelled by its dominance of what analysts call the "new gold or oil in the tech sector" - the chips that power AI. Nvidia, Microsoft and Apple - each worth more than 3tn - are in a three-horse race to be the world's most valuable company.

Nvidia, the startup at the centre of the artificial intelligence boom, has become the world's most valuable company, knocking Microsoft off the top spot. Nvidia's market capitalisation hit 3.335 trillion on Tuesday as shares of the chipmaker rose by 3.5 percent to 135.58. The feat comes just days after the Santa Clara California-based company eclipsed Apple to become the world's second most valuable company. Shares of Microsoft and Apple, holders of the no 2 and no 3 spots, fell by 0.45 percent and 1.1 percent, respectively. Nvidia's rally, which has lifted the S&P 500 and Nasdaq indexes to record highs, continues a speculator winning streak for the company, whose graphics processing units (GPUs) are integral to the development of AI.

Nvidia became the world's most valuable company after its share price climbed to an all-time high on Tuesday. The stock ended the trading day at nearly 136, up 3.5%, making it more valuable than Microsoft. Nvidia makes computer chips needed for artificial intelligence (AI) software, and demand for its products has boosted its sales and profits over the last few years. Many investors believe its earnings can grow even more, which has caused its share price to soar, though some have questioned its sky-high valuation. Tuesday's share price rally means the market now values the company at 3.34tn ( 2.63tn), with the price having nearly doubled since the start of this year.

In the mid 2010s, researchers at AI labs began using Nvidia GPUs as they tinkered with evermore capable AI. The company took notice, and began improving the software used to program its chips to make it more suited to AI work. By the time the AI boom happened, most of the industry was accustomed to using Nvidia's chips and software. Other chip companies, like AMD and Intel, have scrambled to catch up, but industry analysts and AI researchers say that Nvidia will continue to benefit from its head start for years.

Nvidia became the world's most valuable company on Tuesday, dethroning tech heavyweight Microsoft, as its chips continue to play a central role in a race to dominate the market for artificial intelligence. Shares of the chipmaker climbed 3.2% to 135.21, lifting its market capitalization to 3.326tn, just days after overtaking the iPhone maker Apple to become the second most valuable company. The stock has surged about 173% so far this year, compared with a rise of about 19% in Microsoft shares, with demand for its top-of-the-line processors outpacing supply. Tech giants Microsoft, Meta Platforms and Google-owner Alphabet are racing to build out their AI computing capabilities and dominate the emerging technology. The surge in shares pushed the stock to a record high, adding more than 103bn to Nvidia's market capitalization on Tuesday.

Shares of Nvidia rallied to record highs on Wednesday, with the artificial-intelligence chipmaker's stock market valuation hitting the 3tn mark and overtaking Apple to become the world's second most valuable company. The chipmaker's stock was up 5.16% at 1,224.40, giving Nvidia a market value of 3.01tn at market close. Apple's market capitalization was at 3.00tn at market close as its stock climbed 0.78%. The latest rally for Nvidia comes as it prepares to split its stock 10-for-one, effective on 7 June, a move that could increase its appeal to individual investors. The surge in Nvidia's stock market value above Apple's underscores a shift in Silicon Valley, where the company co-founded by Steve Jobs has dominated since it launched the iPhone in 2007.
