AI Chip Stocks Plunge Amid AI-Spending Skepticism and Geopolitical Tensions

Market Slide Overview
U.S. equity indexes recorded a broad decline on Friday, with the S&P 500 down about 1 percent, the Dow Jones Industrial Average off roughly 0.8 percent, and the Nasdaq Composite slipping 1.4 percent. The downturn was led by artificial-intelligence-related chipmakers: Nvidia fell 2.2 percent, Applied Materials dropped 5.5-5.6 percent, and Taiwan Semiconductor Manufacturing Co. (TSMC) lost between 3 percent and 7.3 percent despite posting a record second-quarter profit. The sell-off extended a month-long slide that has erased more than $1 trillion in semiconductor market value.
Drivers of the Sell-off
Analysts point to three intertwined forces. First, earnings reports from major chipmakers showed strong results but were accompanied by announcements of higher-than-expected capital expenditures for AI infrastructure, prompting investors to penalize “overspending.” Second, profit-taking after a prolonged rally is intensifying as traders lock in gains amid uncertainty about whether AI-related spending will translate into near-term profits. Third, external pressures—including a possible Federal Reserve rate hike (futures markets assign a 52 percent probability of a September increase) and rising oil prices above $85 a barrel due to renewed Middle-East hostilities—are raising financing costs for capital-intensive AI projects.
A parallel concern stems from China’s launch of the low-cost Kimi K3 large-language model, which analysts say could curb demand for expensive U.S. AI chips and further dampen spending outlooks.
Data & Statistics
- Nasdaq 100 fell more than 2 percent; the Philadelphia Semiconductor Index (SOX) dropped 4.7 percent on July 7, slipping below its 50-day moving average.
- The VanEck Semiconductor ETF (SMH) traded near $569 after a 5 percent decline on July 1 and a cumulative 13 percent drop over ten sessions.
- Semiconductor stocks have collectively shed roughly $1.3 trillion in market capitalization, according to Forbes.
- Nvidia, the world’s largest company by market cap, posted a 9 percent year-to-date gain, while Micron’s stock has risen 197 percent this year.
Official Statements & Responses
Federal-reserve market data indicate a 52 percent chance of a September rate hike, a factor that could increase borrowing costs for AI-heavy chipmakers. TSMC’s earnings release highlighted a profit beat and revenue beat but also disclosed a higher capex forecast, which market participants interpreted as a red flag for future spending.
Criticism & Opposition
Critics argue that the scale of AI-related investment is unsustainable without demonstrable profit generation. They warn that “the considerable costs have put pressure on AI to deliver stratospheric profits, but there is little evidence to suggest businesses or everyday users will get enough value to warrant forking over a mountain of cash.” The same analysts note that “the technology must deliver within years rather than decades, since the current level of spending cannot be sustained.”

- “The technology must deliver within years rather than decades, critics add, since the current level of spending cannot be sustained.” — Analyst, ABC News
- “The situation showed something that's been true for a while in the market: You'll be punished more for overspending than you'll be rewarded for beating earnings forecasts.” — Business Insider commentary
- “Morgan Stanley characterized the recent drop as a “mid-cycle reset” rather than a market peak.” — Morgan Stanley analyst, ECIKS report
- “Jim Reid, an analyst at Deutsche Bank, said global equities were continuing to slump as fresh doubts over the AI trade drove a pronounced sell-off in tech stocks.” — Jim Reid, Deutsche Bank
Conflicting Reports & Gaps
Sources differ on the magnitude of index declines: the Associated Press cites a 1 percent S&P drop, while ABC News describes it as “nearly 1 percent.” Dow losses are reported as 0.8 percent (AP) versus 0.7 percent (ABC). TSMC’s share decline ranges from “more than 3 percent” (ABC) to “7.3 percent” (Share-talk) and “6 percent” (Business Insider). No direct statements from the companies themselves are provided, leaving the rationale behind the heightened capex forecasts opaque.
What’s Next
The second-quarter earnings season intensifies through late July and early August. Upcoming reports include TSMC (July 16), Intel (July 23), Seagate (July 28), Lam Research, SK Hynix, Arm, Qualcomm (July 29), AMD (August 4), and SanDisk (August 5). Market participants will watch these filings for signs that AI-related spending can be justified without further eroding chip valuations.
