BOSTON/LONDON/SINGAPORE: U.S. stock futures steadied, the dollar ticked higher and tech stocks in Asia slid on Tuesday following a wave of selling as apparent advances by a Chinese AI startup cast doubt on U.S. dominance and spending in one of the market’s hottest sectors.
Overnight, chipmaker Nvidia tab dived 17%, wiping off nearly $593 billion in the biggest market capitalisation loss in history.

Nvidia stock was up slightly in after-hours trading. Nasdaq 100 futures rose 0.1% and S&P 500 futures were broadly flat.
Nvidia supplier Advantest was down 10% in Japan on Tuesday, taking losses for the week so far to nearly 19%.

Data centre landlords tumbled in Australia. Tech heavy markets in Taiwan and South Korea were closed for a holiday.
Nvidia accounted for most of the 3% drop in the Nasdaq on Monday though selling extended from Tokyo to New York and hit everything with a slice of the AI supply chain, from cable makers to data centres, power utilities and software firms.

“The narrative that’s concerning people here is that DS … has delivered performance-topping models on a shoestring budget,” said J.P. Morgan sector specialist Josh Meyers in a note to clients.
“This has been seen by some as egg-on-the-face of the big, multi-billion dollar operations like OpenAI, Google and Anthropic.
And it’s calling into question whether we’re going to need multi billions of dollars in compute capex when DeepSeek’s leading distilled models can run natively on an iPhone.“
On Wall Street, the S&P 500 (.SPX), opens new tab dropped 1.5%. Chipmaker Broadcom fell 17.4% and the Philadelphia semiconductor index dropped 9.2% - its biggest loss since March 2020.
