Chip Stocks Crash Up to 8% as AI Rally Doubts Shake Nasdaq

Semiconductor Stocks Face Sharp Sell-Off on AI Valuation Fears

Global chip stocks suffered a bruising session on July 7, with Micron shedding around 7.3% and Intel plunging approximately 8.2%, dragging technology-heavy indices lower across the United States and Asia. The sell-off came despite Samsung reporting robust quarterly earnings, suggesting that positive results from one player were insufficient to restore confidence in the sector’s lofty valuations.

Samsung Earnings Fail to Reassure Markets

Investors had been hoping that strong numbers from Samsung would validate the enormous capital expenditure being funnelled into AI-related semiconductor infrastructure globally. Instead, Samsung’s shares fell in South Korea, signalling that the market was looking beyond near-term earnings and focusing on longer-term questions about custom chip development, the concentration of AI spending and whether demand can justify current valuations across the semiconductor supply chain.

The weakness rippled outward. Intel and Micron saw some of the steepest declines, as both companies have significant exposure to the AI-driven memory and data centre chip market that has powered their recent stock rallies.

DeepSeek’s Chip Push Adds to Uncertainty

Complicating sentiment further, reports about DeepSeek’s expanding AI chip ambitions rattled markets, raising fresh questions about competitive dynamics in the AI hardware space. If alternative, potentially more cost-efficient AI infrastructure approaches gain traction, the premium that investors have assigned to incumbent semiconductor companies could come under sustained pressure.

Nasdaq and S&P 500 Feel the Pain

At the index level, the Nasdaq Composite lost approximately 1.02% in early trading, reflecting the outsized weight that large-cap technology and chip-related companies carry within the index. The S&P 500 declined around 0.34%, while the Dow Jones Industrial Average was broadly flat, suggesting that the pain was concentrated in the technology and semiconductor sub-segments rather than the broader economy.

S&P 500 and Nasdaq futures had already pointed to a weak open earlier in the day, with Nasdaq futures falling around 0.8% in pre-market trading as the Asian weakness spread westward.

Broader Implications for AI-Linked Stocks

The session’s events underline a growing divide in how investors are approaching the AI trade. After an extended, AI-fuelled rally that lifted semiconductor valuations to historically elevated levels, markets appear to be entering a more discerning phase — one where earnings delivery and realistic demand projections matter more than narrative alone. Investors will be watching upcoming earnings from major technology companies closely for signs of whether AI capital spending remains on an upward trajectory.
