Global Tech Rout Erases $1 Trillion Across AI and Chip Stocks as Funding Pressures Mount

A sweeping sell-off across artificial intelligence and semiconductor equities deepened on Thursday, with 20 of the sector's most valuable global companies losing more than $1 trillion in collective market value this week, according to reporting by CNBC Business (https://www.cnbc.com/2026/10/15/sk-hynix-samsung-softbank-stocks-asia-tech-rout-ai-funding-worries.html). The downturn reflects mounting unease over rising interest rates, the towering capital costs required for AI infrastructure, and long-term hardware supply dynamics.

In the United States, hardware and chip providers faced broad afternoon pressure. Nvidia dropped approximately 2%, while Advanced Micro Devices and Intel each lost around 4%. Server vendor Dell Technologies dropped 8%, and Micron Technology traded down marginally after sharp fluctuations. Among specialized cloud infrastructure firms, Nebius fell about 2% and IREN declined roughly 4%. CoreWeave bucked the downward trend to gain 3% in afternoon trading after Nvidia Chief Executive Jensen Huang told Bloomberg at an event in Stockholm, Sweden, that Nvidia did not need to backstop the company, adding, "Their cost of capital is actually decreasing."

The retreat hit Asian markets particularly hard. In South Korea, SK Hynix dropped over 10% and Samsung Electronics lost 8.73%, alongside declines across suppliers including LG Innotek (down 8.95%), Seoul Semiconductor (down 9.28%), and Samsung SDI (down 6.26%). Japanese equities saw SoftBank Group fall 7.9%, chip testing supplier Advantest plunge nearly 14%, Tokyo Electron fall 6.45%, and Renesas Electronics drop 8%. In Taiwan, contract manufacturer TSMC slipped 1.81%. In Europe, ASML traded marginally lower, while Infineon Technologies fell 5% and ASM International dropped 7%.

The international losses followed a negative Wednesday session on Wall Street sparked by hotter-than-expected inflation data that stoked fears of further Federal Reserve interest rate hikes. The Nasdaq Composite fell 1.88% to close at 26,692.87, the S&P 500 declined 1.11% to 7,718.94, and the Dow Jones Industrial Average dropped 0.09%.

Financing anxieties have increasingly surfaced among industry leaders. On Monday, Broadcom Chief Executive Hock Tan and the chief executive of Intel warned that capital availability could become a primary obstacle to AI expansion, with Tan indicating that funding could prove more challenging than shortages of silicon or power. Investor sentiment was also pressured by projections of potential global memory oversupply by 2029 as manufacturers expand capacity, alongside competitive developments from China's ChangXin Memory Technologies (CXMT), which announced a high-density memory architecture breakthrough over the weekend.

Despite U.S. Treasury yields rising above 5%, some market analysts view the drawdown as a financing reassessment rather than an operational slowdown. Dan Ives, tech analyst at Yorkville Ives, noted that while higher yields raise infrastructure funding costs, underlying demand for AI compute remains firm. Ives framed the decline as a buying opportunity, emphasizing that a genuine shift in industry fundamentals would require operational warnings such as reduced hyperscaler capital expenditure budgets, canceled customer contracts, or dropping GPU rental rates.
