On October 15, 2026, Nvidia, AMD, Dell, and Asian chip stocks fell as higher borrowing costs and AI financing fears sparked a global tech rout. The sell‑off matters because it signals the AI boom is maturing: a projected memory‑chip oversupply by 2029 could squeeze semiconductor margins and slow data‑center spending.
What Happened
On October 15, 2026, a global tech rout unfolded as AI‑focused semiconductor and hardware stocks plunged. Nvidia shares fell about 2%, AMD sank more than 2%, Intel lost about 4%, and Dell Technologies dropped 9%. Micron shares whipsawed, ending marginally lower in the afternoon, while CoreWeave rebounded, up nearly 5% after CEO Jensen Huang’s comments at a Stockholm event. Nebius and IREN traded marginally lower, with IREN down about 3%. In Asia, SK Hynix plunged more than 10%, Samsung Electronics fell 8.73%, LG Innotek sank 8.95%, Seoul Semiconductor shed 9.28%, and Samsung SDI declined 6.26%. SoftBank Group tumbled 7.9%, Advantest plunged almost 14%, Tokyo Electron lost 6.45%, and Renesas Electronics declined 8%. Taiwan’s TSMC fell 1.81%, while Dutch ASML traded marginally lower, Infineon Technologies shed 5%, and ASM International was down 7%.
Investors cited higher borrowing costs and AI financing worries as the primary drivers of the sell‑off. Concerns that rising interest rates could curb the massive capital spending required to build AI infrastructure weighed heavily on sentiment. Additionally, fears of a global memory‑chip oversupply as manufacturers ramp up capacity to meet surging AI demand surfaced early in the week.
Huang told Bloomberg that he “didn’t see a need for Nvidia to backstop CoreWeave and that, ‘Their cost of capital is actually decreasing.’” This statement helped calm some fears in the AI trade, allowing CoreWeave to rebound.

Why It Matters
This rout suggests that the AI boom is reaching a maturity point where macroeconomic forces—particularly interest rates—can no longer be ignored. The sharp decline in AI‑centric stocks indicates that investors are re‑evaluating the cost of capital required to sustain AI infrastructure growth. If borrowing costs remain high, we could see a slowdown in new data‑center construction and a shift toward more efficient, edge‑based AI solutions.
The memory‑chip oversupply warning points to a potential correction in the semiconductor supply chain. A glut could depress prices, squeezing margins for manufacturers and forcing them to innovate faster to maintain profitability.
Moreover, the sell‑off across both U.S. and Asian markets shows that AI funding concerns are global. Companies that can navigate cross‑border financing challenges and maintain supply‑chain resilience will be better positioned to weather future downturns.
Key Takeaway
- Nvidia, AMD, Intel, and Dell Technologies all fell between 2% and 9% on October 15, 2026.
- Higher borrowing costs and AI financing worries drove the global tech rout.
- CoreWeave rebounded after Jensen Huang’s reassurance that its cost of capital is decreasing.
- Memory‑chip oversupply fears could depress semiconductor prices by 2029.
Frequently Asked Questions
What caused the sharp decline in AI‑related stocks?
Investors reacted to higher borrowing costs and concerns that AI infrastructure spending could be curtailed, leading to a sell‑off across the sector.
How might the memory‑chip oversupply affect the industry?
A projected oversupply by 2029 could lower chip prices, squeezing margins for manufacturers and potentially slowing new production investments.
Will Nvidia’s statement about CoreWeave’s cost of capital change the market outlook?
Huang’s comment helped calm fears for CoreWeave, allowing the stock to rebound, but the broader market remains sensitive to financing conditions.
