Global chip stocks slide as investors doubt AI spending returns
Chip makers' shares tumble from South Korea to New York as investors question whether huge AI infrastructure spending will pay off.
The Full Story
A plain summary built from the channels that reported this story.
Shares in some of the world's largest computer chip makers fell sharply overnight, as investors questioned whether massive spending on artificial intelligence will produce adequate returns. The sell-off hit Asia first and then continued in the United States.
South Korea's stock market dropped by 10% in a single day. Japan also fell. In New York, the decline continued into the afternoon. Two companies led the fall in South Korea: Samsung was down 13%, and SK Hynix was down 15%.
SK Hynix's share price had rocketed this year as the AI boom took hold, but it has been falling for weeks as investor doubts have grown. The wider concern is the economics of AI. Chip makers sell their products to companies that plan to build AI infrastructure, and those buyers are preparing to spend enormous sums.
Reuters compiled the capital spending plans of five large US technology firms. They plan to spend three quarters of a trillion dollars this year, a fivefold increase on three years ago, and the total is expected to rise again next year. Not all of that spending is AI related, but a large share is.
Investors are split. Some see the creation of a major new business. Others ask how the companies will earn a return on such huge outlays. China adds another risk. Chinese firms are developing their own chips, chip making equipment and AI models, and some investors fear cheaper Chinese products could undermine the investment now being made.

Channel Perspectives
What each channel focused on, with key quotes.
Channel 4 framed the sell-off as a market-wide test of AI economics, not just a South Korean story. It used Samsung and SK Hynix to explain the boom and the doubts, then widened out to US tech capital spending and the threat from China. The tone was explanatory and cautious, with no corporate or government voices.
- “I think there's an argument that's haunting stock markets across the world, including South Korea's, and it's this.”
- “Is AI a technology that will revolutionise all our economies and so any company behind it and anyone who invests in those companies are going to make a lot of money? Or is the euphoria over AI getting a little bit overdone?”
- “And I think clearly it's that second view which took hold in South Korea last night.”
