U.S. semiconductor stocks extended their losses in premarket trading on Tuesday after a sharp selloff spread across Asian chip markets. Investors became more cautious about artificial intelligence (AI) stocks due to concerns over how massive AI infrastructure projects are being financed and growing competition from China’s semiconductor industry. According to Investing.com, the negative sentiment followed Monday’s decline in Nvidia and quickly spread across global chipmakers.
Nvidia’s 5% Drop Sparks Broad Chip Selloff as Micron, AMD and Intel Extend Premarket Losses
According to Investing.com, several major U.S. semiconductor stocks traded lower before the market opened on Tuesday. Around 04:46 ET, Micron Technology, SanDisk, and Western Digital were each down about 4%, while Intel lost 3.2%. AMD and U.S.-listed shares of SK Hynix both fell more than 3%, Applied Materials and Marvell Technology dropped around 2.8%, and Super Micro Computer declined 2.9%.
The weakness followed Monday’s sharp decline in Nvidia, whose shares fell around 5%, causing the company to lose its position as the world’s most valuable publicly traded company to Apple, according to The Wall Street Journal. The broader weakness also pushed the Philadelphia Semiconductor Index (SOX) lower as investors reduced exposure to AI-related stocks.
AI Infrastructure Costs and China Competition Drive Semiconductor Selloff
The market reacted mainly because investors are becoming more concerned about the huge amount of money being spent on AI infrastructure. According to The Wall Street Journal, Nvidia is in talks to provide a roughly $250 billion financial guarantee to support OpenAI’s lease of a planned 10-gigawatt data center project in southern Ohio. Although no final agreement has been announced, the report raised questions about whether the rapid expansion of AI infrastructure is relying too heavily on large financing commitments.
Another reason behind the selloff is growing competition from China. According to Reuters, Chinese memory chipmaker ChangXin Memory Technologies (CXMT) surged 466% during its stock market debut after raising $8.6 billion in Asia’s largest IPO of 2026. The rally valued the company at about 3.3 trillion yuan (approximately $488 billion), highlighting China’s rapid progress in the semiconductor industry and increasing competitive pressure on global chipmakers.
Markets Await Big Tech Earnings and Nvidia-OpenAI Updates
Investors will now closely watch upcoming earnings reports from major technology companies, including Microsoft, Meta, Amazon, and Apple, for updates on AI spending plans. Markets will also monitor any further developments regarding Nvidia’s reported financing discussions with OpenAI and future progress in China’s semiconductor industry. These events could determine whether the recent selloff is tempfurther orary or signals a broader slowdown in AI-related investments.
