Article summary: The selloff deepened because investors were reassessing the financing costs and sustainability of the AI boom, rather than simply reacting to current chip-company profits: hotter inflation increased rate-hike expectation.

TSMC delivered a sixth consecutive record-profit quarter, yet chip stocks continued to fall on Thursday, October 15, 2026. Investors were weighing the cost and durability of the AI buildout against hotter US inflation, renewed interest-rate concerns and competitive pressure from China.1

Strong results could not settle concerns about the outlook
TSMC reported third-quarter net profit of NT$763.06 billion, up 68.7% year over year, on revenue of US$46.72 billion. Profit beat the LSEG estimate of NT$746.3 billion, and the quarter marked the company’s sixth consecutive record profit.6
The company also forecast fourth-quarter revenue of US$52.3 billion to US$54.3 billion, with the midpoint about 14% above the third quarter.6 But CEO C.C. Wei said TSMC was being prudent in its planning for 2027, citing higher component prices and macroeconomic uncertainty affecting consumer and price-sensitive markets.
1 That caution mattered to investors looking beyond the latest quarter, even as the near-term revenue forecast remained strong.
Inflation revived rate-hike fears
US consumer inflation came in hotter than expected. September headline CPI rose 3.7% year over year, above the 3.6% forecast, while core CPI increased 0.3% month over month against expectations of 0.2%.3
25 Futures markets at one point priced in as much as a 50% chance of another Federal Reserve rate increase in October.

Thursday’s producer-price report added to the concern: core PPI rose 0.7% month over month, compared with a 0.3% forecast. Schwab described it as the largest increase in four years.21 For investors, the inflation readings sharpened the risk that borrowing costs could stay higher or rise further—an unfavorable backdrop for companies and projects that depend on financing.
AI infrastructure debt became a pressure point
The selloff also reflected concern about how the expansion of AI data centers is financed and whether spending will generate sufficient returns. CoreWeave, a data-center operator, became a prominent example of that financing anxiety: one market update reported its shares down 15% and yields on its 2032 bonds above 15%.30 That stress fed into broader concerns about debt-funded AI infrastructure and weighed on chip stocks alongside the inflation news.

Competition added to the sector-wide retreat
Reports of progress by Chinese chipmaker CXMT on a new memory architecture added another source of uncertainty, particularly for memory-chip companies.11 The concern was not limited to firms with weak results: reporting said strong results from TSMC and ASML did not shield their shares from the broader selloff.

How far the selloff spread
A closely watched semiconductor index fell 2.5% on Thursday, its seventh consecutive declining session, according to CNN’s report.2 The previous day, chip stocks had already dropped sharply, with Schwab reporting a decline of about 4% and the Philadelphia Semiconductor Index more than 10% below the prior week’s peak.
21
The pressure crossed regions. South Korea’s Kospi closed 7.6% lower after a circuit breaker, while in Europe ASML fell 6.5% and STMicroelectronics dropped 7% in Thursday trading.11
23 In the United States, the Nasdaq was down about 0.8% shortly after the market opened.
46
Taken together, the evidence points to a repricing of AI-related risk rather than a rejection of TSMC’s earnings: investors were balancing strong current demand against higher financing costs, uncertainty about future spending and competition. The reports cited here do not establish a precise contribution from Middle East developments or verify the full sequence of later market moves, so those factors should not be treated as confirmed explanations for the chip selloff.
