The United States stock market has hit an all-time high as excitement around artificial intelligence continues to fuel a buying frenzy on Wall Street. The S&P 500, the benchmark stock index, closed 0.58 percent higher on Tuesday, topping the previous peak reached in mid-August. Tech stocks were among the top performers, with each of the "Magnificent Seven" apart from Meta closing higher. Amazon led the pack with a 1.95 percent gain, followed by Microsoft and Tesla, which rose 0.78 percent and 0.51 percent, respectively. Apple and Alphabet both rose 0.22 percent, while Nvidia gained 0.14 percent.

The telecom giant is eager to show Wall Street that it can do more with less. That means fewer employees, less electricity, and increased automation. AT&T, which already shed more than half of its workforce over the past decade, says it's going to continue laying off staff as it gears up for the AI era . The telecommunications giant is also doing away with its old-school landline service and using artificial intelligence to automate some internal processes. All this downsizing is resulting in tangible benefits, including a considerable decrease in electricity usage, AT&T chief technology officer Jeremy Legg tells WIRED.

Wall Street's Nasdaq hits all-time high as AI frenzy gathers pace Share Wall Street's Nasdaq hits all-time high as AI frenzy gathers pace on social media Wall Street's Nasdaq stock exchange has hit an all-time high, shrugging off concerns about AI safety risks, sky-high tech valuations and the energy shock caused by the United States' war on Iran. The Nasdaq Composite index, which is dominated by US tech giants such as Nvidia, Apple and Microsoft, rose 0.45 percent on Tuesday, taking its gains to date this year to more than 17 percent. The S&P 500, the most popular measure of the overall US stock market, closed essentially flat. Monolithic Power Systems, a Florida-based manufacturer of power circuits, and Canadian e-commerce company Shopify led the gains, surging 8.1 percent and 7.1 percent, respectively. Micron Technology, one of the world's top three memory chip makers along with South Korea's SK Hynix and Samsung Electronics, rose 5 percent.

As China and the U.S. race to build separate artificial intelligence supply chains, investors are playing both sides, with U.S. banks fundraising for AI upstarts in China and Chinese money flowing to U.S. tech. The stakes are sizable, with Wall Street banks acting as book-runners on 19 Chinese high-tech equity capital market deals worth $17.2 billion so far this year, according to LSEG data, accounting for nearly 30% of the sector's total issuance. U.S. stocks, particularly semiconductors, are also the favorite destination for China's outbound mutual funds. The value of U.S. equity held by Hong Kong residents and mainland Chinese has jumped 23% in the past year to top $750 billion, U.S. data shows. In a time of both misinformation and too much information, quality journalism is more crucial than ever.

AI's wobbly house of cards puts markets and U.S. economy at risk Protesters during a demonstration calling for a slowdown in the development of advanced artificial intelligence systems outside city hall in San Francisco on Thursday. The heads of America's leading AI development labs have started a national conversation about tapping the brakes on a technology that's offering so much promise for society, while at the same time showing it can do a frightening amount of harm. It's a debate that needs to be had, and a real solution invariably will be hard to come by. But considering the trillions of dollars of investment gains and market value that have been built on the assumption that AI will keep growing at breakneck speed for years and years to come, what happens to Wall Street -- and more importantly Main Street -- if it doesn't? "People may not fully grasp just how wound up the market and the economy is in all of this," said Jim Morrow, chief executive officer of the Boston investment firm Callodine Capital Management.

Image caption, Nvidia's business has grown significantly amid the AI boom. Chip giant Nvidia has reported another huge jump in sales as the global push to build artificial intelligence (AI) systems continues at a rapid pace. The company said on Wednesday that it brought in $96bn (£71bn) of revenue during the second quarter, more than double the amount for the same period a year earlier. And it expects revenue of $108bn in the next quarter. AI has reached its inflection point, CEO Jensen Huang said in prepared remarks, describing the infrastructure buildout as going at full steam. The revenue figures beat Wall Street's expectations, leading Nvidia shares to rise by 4.7% in after-hours trading.
