AI-Fueled Stock Rally Dealt $1 Trillion Blow by Chinese Upstart · Bloomberg

(Bloomberg) -- For the better part of two years, artificial intelligence technologies have been a nonstop gift for US equities investors. The Nasdaq 100 Index rose 92% from the start of 2023, adding more than $14 trillion in value and minting billions for a handful of tech executives and founders.

Just last week, the S&P 500 Index powered to another record thanks in large part to more AI hype, this time from the Oval Office in the form of $500 billion in planned investments. President Donald Trump declared the US the global AI leader — a statement few would’ve contested long before he even uttered it. Nvidia Corp. had the best chips. Meta Platforms Inc., OpenAI and other US tech giants had significant leads in developing the bots that would drive it.

Then came DeepSeek, a Chinese startup whose AI platform appears to look as good as anything on the market at a fraction of the price and a sliver of the energy consumption.

The Nasdaq 100 fell 3% Monday, the most in six weeks, leaving it virtually flat for the year and worth almost $1 trillion less than on Friday. Nvidia had its worst day since March 2020 when the pandemic hit, losing almost $600 billion in market value in the biggest wipe-out in history. Energy firms expected to profit from unprecedented AI demand sank, led by a 21% beatdown for Constellation Energy Corp.

Suddenly, a rally predicated largely on US AI dominance turned into a question of whether the hundreds of billions in AI investments would ever lead to profits large enough to justify the rich valuations afforded to Megacap stocks. The group makes up 30% of the S&P 500’s by weighting, more than at any time in history.

“Today’s moves show just how precarious this market set up is,” Max Gokhman, senior vice president at Franklin Templeton Investment Solutions. “When valuations stretch to the sky it’s easier for small trembles to make the entire market rumble.”

DeepSeek’s latest AI model rose to the top of the Apple’s appstore charts over the weekend, presenting a visible challenge to costlier models like OpenAI and raising questions over the hundreds of billions in planned spending on the technology by the likes of Meta, Microsoft Corp. and Alphabet Inc. Nvidia, whose shares soared ninefold in the past two years, tumbled 17%.
