Global chipmaker sell-off deepens as enthusiasm for AI stocks wobbles

Global Chip Stocks Slide as Confidence in AI Trade Fades

Activelifezero.com – Investors pulled back sharply from semiconductor shares on Thursday as concerns over artificial intelligence spending, elevated valuations and rising borrowing costs spread through markets worldwide. The retreat extended across major chipmaking centers in the United States, Taiwan, South Korea and Japan, while government bonds and less technology-dependent sectors attracted renewed demand.

A widely followed US semiconductor index fell 2.5%, marking its seventh consecutive daily decline. The sector has now dropped more than 20% from its June high, illustrating how quickly enthusiasm for companies central to the AI infrastructure boom has weakened after a powerful earlier rally.

The Nasdaq Composite was down 0.3% after recovering from a steeper early loss. Buying in some recently battered companies and gains among software stocks helped limit the decline. The S&P 500 also opened lower following new inflation data but later recovered to trade roughly flat as investors shifted money away from AI-focused stocks and into other parts of the market.

Inflation and financing fears reshape the AI outlook

September wholesale inflation in the United States rose at its fastest pace in more than four years, reinforcing investor concern that interest rates could remain higher or rise further. That matters especially for AI companies and data-center operators, many of which require enormous capital outlays for advanced chips, computing capacity and power-intensive infrastructure.

Higher rates raise the cost of debt and can make long-term growth projections less attractive to investors. The pressure has become particularly visible among companies tied to the rapid expansion of AI computing capacity.

CoreWeave, a Nvidia-backed provider of data-center and computing services, has drawn close attention because it carries tens of billions of dollars of debt. Its shares plunged 15.5% on Wednesday as investors assessed how a more expensive financing environment could affect its outlook. The stock initially declined again Thursday before reversing course after Nvidia Chief Executive Jensen Huang expressed optimism about the company in comments to Bloomberg.

Specialized AI cloud providers, often called neoclouds, have become a key focus of the market’s reassessment. These businesses aim to supply the large-scale computing resources needed to train and operate AI models, but their expansion can depend heavily on access to financing and sustained customer demand.

Growth expectations face tougher scrutiny

The sell-off followed Wall Street’s worst technology-led session since July on Wednesday. Shares linked to the AI buildout, including chipmakers, fell as investors questioned whether future revenue growth can continue to support already lofty market values.

“Worries about the AI buildout, bubbly valuations, lower-than-expected earnings growth at leading US frontier labs, Chinese competition, inflation and rates sent investors running for the covers.”

Neil Wilson, a strategist at investment bank Saxo, said signs that revenue growth was slowing at Anthropic and OpenAI had added to the unease. Anthropic disclosed during an investor presentation ahead of an anticipated initial public offering that quarterly sales rose 45% to $17 billion. That growth rate was slower than the more than doubling of sales recorded in the second quarter.

The market reaction does not erase the broader expansion in AI investment. Semiconductor manufacturers have benefited this year from rising demand for equipment used in data centers. However, investors are increasingly distinguishing between the long-term potential of AI and the near-term financial demands of building the infrastructure behind it.

Asian technology markets absorb heavy losses

Pressure was especially intense across Asia, where several of the world’s most important chip manufacturers are based. Taiwan Semiconductor Manufacturing Company, the leading producer of advanced chips, finished 2% lower despite posting strong earnings. Its results were overshadowed by caution from Chief Executive C.C. Wei, who told analysts that higher component prices and broader economic uncertainty were weighing on demand in some market segments.

That decline helped push a Taiwan technology-stock index down 3.5%.

South Korea’s Kospi suffered the sharpest regional fall, closing 7.6% lower after major losses in its dominant semiconductor names. SK Hynix dropped 11%, while Samsung Electronics fell 9.5%. The size of the sell-off triggered a circuit breaker that temporarily stopped trading on the exchange.

The Kospi ended at a six-month low, wiping out all gains recorded since April. The index had been up as much as 116% for the year in June, driven largely by the performance of Samsung and SK Hynix, before falling by more than one-third. Its gain for the year stood at 32% after Thursday’s close.

Japan’s Nikkei fell 4.9%, while Hong Kong’s Hang Seng Index lost 1%. The breadth of the moves reflected a reassessment of the global supply chain supporting AI, from memory chips and advanced processors to the companies operating the facilities that house them.

Chinese competition adds another concern

Competitive developments in China have further complicated the outlook for established chipmakers. Chinese semiconductor company CXMT has announced progress in advanced memory chips, prompting investors to consider whether new competition could narrow profit opportunities for companies in South Korea and the United States.

Memory technology is essential to AI computing because advanced models require large volumes of data to be processed quickly. Any meaningful increase in supply or capability from competitors could affect pricing, margins and market-share expectations across the sector.

For investors, Thursday’s trading showed that the AI theme remains powerful but no longer commands unquestioned confidence. Semiconductor companies are still central to the buildout of advanced computing systems, yet markets are demanding clearer evidence that spending plans, revenue growth and debt-funded expansion can withstand higher rates and more competitive conditions.
