• US chip-related shares fell sharply, with Nvidia (NVDA) down 3%, AMD (AMD) 5%, Intel (INTC) 5.9%, and Marvell Technology (MRVL) off 5.5%.
  • The selloff stems from hotter-than-expected inflation, rising borrowing costs, and growing doubts over financing the AI infrastructure boom.
  • Strong recent earnings from these companies have not shielded their shares from a broader reassessment of AI-related valuations.

Broad Selloff Hits Semiconductors

Shares of major US chipmakers tumbled on Wednesday, with Nvidia dropping 3%, AMD falling 5%, Intel losing 5.9%, and Marvell Technology off 5.5%. The declines came amid a wider market rout that saw the Nasdaq shed 1.9% and the S&P 500 decline 1.1%, as investors grappled with a hotter-than-expected inflation report and its implications for interest rates.

The selloff was not confined to chipmakers. AI-cloud provider CoreWeave (CRWV) plunged 15.5%, Oracle (ORCL) dropped 8.8%, and power-equipment supplier GE Vernova (GEV) lost 6.2%, underscoring that investors are repricing the entire AI investment chain. According to people familiar with the matter, the moves reflect growing concerns that the massive capital expenditures required for AI infrastructure may become harder to finance in a higher-for-longer rate environment.

Inflation Report Sparks Rate Worries

The trigger for the latest leg down was September’s consumer price index, which rose 3.7% year over year, up from 3.4% in August and above economists’ expectations of 3.6%. The 10-year Treasury yield briefly exceeded 5.32%, stoking fears that the Federal Reserve could tighten further. Market-implied odds of a rate hike at the next Fed meeting jumped to nearly 35% from 22% a day earlier, according to CME (CME) data cited by the Associated Press.

The inflation surprise compounded existing pressures on chip stocks, which had already been under scrutiny due to intensifying Chinese competition in memory chips and doubts about AI spending. Reuters (TRI) reported another sector decline on October 13, before the CPI release amplified the downdraft.

Strong Earnings Fail to Insulate

The selloff is notable because it comes despite robust revenue growth across the sector. Nvidia’s fiscal Q2 2027 revenue reached $96.2 billion, up 106% year over year, with data-center revenue surging 117%. AMD posted calendar Q2 2026 revenue of $11.5 billion, up 50%, while Intel’s revenue rose 25% to $16.1 billion. Marvell’s fiscal Q2 2027 revenue grew 37% to $2.739 billion, with data-center growth accelerating to 46%.

“What institutional investors like us are really focused on is regulatory stability,” said Andrea Valeri, Blackstone (BX)’s country chairman for Italy and chief investment officer for Blackstone Credit and Insurance’s private credit business in Europe and APAC, speaking at the Bloomberg Future of Finance conference in Milan. While his comments were about Italy, they echo a broader theme: investors are increasingly prioritizing predictability, both regulatory and monetary, over raw growth.

The central contrast is that these shares are falling despite strong operating results. The market is questioning the financing, durability, and valuation of future growth—not reacting to a collapse in current sales.

AI Financing Concerns Mount

Data centers require large upfront investments, and more expensive borrowing can make new projects harder to finance, potentially slowing purchases of chips, networking equipment, and power infrastructure. Higher bond yields also put downward pressure on stock valuations, particularly for companies priced for rapid future growth.

The financing risk can spread through the supply chain. Weakness in cloud operators, chipmakers, and electricity-equipment suppliers shows that investors are assessing the whole ecosystem, not just GPU demand. Broadcom (AVGO) and Intel executives warned earlier this week that access to capital could become a major constraint on AI expansion. Broadcom CEO Hock Tan suggested financing could become a greater challenge than chip or electricity shortages.

Chinese Competition Intensifies

China’s ChangXin Memory Technologies, or CXMT, reported a memory-architecture breakthrough that could increase density. That has intensified concerns about competition and possible memory oversupply as early as 2029. These are prospective risks, not evidence that an oversupply already exists.

The implications differ by company. Memory manufacturers face the most direct pricing threat; Nvidia, AMD, Intel, and Marvell are also being affected by broader concern about AI spending and semiconductor valuations. Treating all chip businesses as economically identical would obscure those differences.

Intel’s Restructuring Continues

Intel remains the most prominent restructuring story among the four. CEO Lip-Bu Tan’s efficiency program includes further targeted job reductions affecting channel-facing operations, following the company’s previously announced 15% workforce reduction in 2025. Intel described the latest changes as part of becoming leaner and faster-moving.

The reporting reviewed does not identify a new leadership change at Nvidia, AMD, or Marvell as the immediate trigger for this sector-wide decline.

Global Contagion

The decline spread internationally. Thursday reporting showed SK Hynix (000660.KS) down more than 10%, Samsung Electronics (005930.KS) down 8.73%, and significant losses in Japanese and European semiconductor-related companies. CNBC reported that 20 major global AI and semiconductor stocks had collectively lost more than $1 trillion in market value during the week.

ASML (ASML)’s strong earnings did not prevent further weakness in US chip stocks. Marvell’s latest quarterly results showed continued strong data-center growth despite the market’s reassessment of AI-related shares. The selloff reached cloud services, power equipment, semiconductor testing, and chipmaking equipment across multiple countries.

What’s Next

Short term, the most consequential variables are Treasury yields, expectations for Fed tightening, and evidence that AI customers can finance their spending commitments. Strong earnings alone may not stabilize the sector if financing costs continue to rise or investors demand lower valuations.

Technology analyst Dan Ives, quoted by CNBC, favors the view that higher rates are a financing problem rather than evidence of weak underlying AI demand. He identified cuts to hyperscaler capital spending, canceled contracts, and falling GPU rental prices as signals that would challenge that view. His assessment is an analyst opinion, not an established outcome or universal consensus.

The most useful distinction going forward is between falling stock prices and deteriorating customer demand. Current company results remain strong; whether financing pressure turns into actual spending cuts is the unresolved question.
