$955 billion meltdown: Wall Street darling suffers biggest one-day loss in history​on January 27, 2025 at 6:54 pm

Nvidia’s plunge, fuelled by investor concern about Chinese artificial-intelligence startup DeepSeek, erased a record amount of stock-market value from the world’s largest company.

Nvidia shares tumbled after the opening bell, and are 17 per cent lower in mid-afternoon trade, erasing about $US600 billion ($955 billion) from the company’s market capitalisation. That eclipsed the previous record — a 9 per cent drop in September that wiped out about $US279 billion in value — and was the biggest in US stock-market history.

The drop rippled through the rest of the market due to how much weight Nvidia has in major indexes. Including Monday’s slump, Nvidia selloffs have caused eight of the top ten biggest one-day drops in the S&P 500 Index, based on market value, according to data compiled by Bloomberg. The S&P 500 fell as much as 2.3 per cent early in the session and the Nasdaq 100 tumbled as much as 3.6 per cent before paring the drop.

The semiconductor maker is leading a broader selloff in technology stocks after DeepSeek’s low-cost approach reignited concerns that big US companies have poured too much money into developing artificial intelligence, since the Chinese firm appears to provide a comparable performance to Western chatbots at a fraction of the price.

The latest AI model of DeepSeek, released last week, is widely seen as competitive with those of OpenAI and Meta. The open-sourced product was founded by quant-fund chief Liang Wenfeng and is now at the top of Apple’s App Store rankings.

“Concerns have immediately emerged that it could be a disruptor to the current AI business model, which relies on high end chips and extensive computing power and hence energy,” Jefferies analysts said in a note to clients.

Nvidia has been the biggest beneficiary of the influx in spending on AI because they design semiconductors used in the technology. While that heavy spending looks poised to continue, investors may be more wary of rewarding companies that aren’t showing a sufficient return on the investment.

Meta announced plans on Friday to boost capital expenditures on AI projects this year by about half to as much as $US65 billion, sending its shares to a record high. That came on the heels of OpenAI, SoftBank Group and Oracle announcing a $US100 billion joint venture called Stargate to build out data centres and AI infrastructure projects around the US.
