U.S. Chip Stocks Extend Losses Amid AI Financing and China Competition Fears

U.S. semiconductor stocks extended their decline in premarket trading Tuesday, caught in a global rout of artificial intelligence-related shares. The selloff, which began in the U.S. on Monday, is fueled by mounting investor concerns over the financing of massive AI infrastructure projects and intensifying competition from China.

Global Selloff Deepens

The weakness in U.S. futures follows a turbulent session in Asia, where major chip-related indexes saw steep declines. South Korea’s Kospi index tumbled 10.8%, with heavyweights Samsung Electronics and SK Hynix falling 13% and 15%, respectively. In Japan, the Nikkei 225 dropped 4%, led by losses in semiconductor firms.

In U.S. premarket trading, the downturn was broad-based among chipmakers as of 04:46 ET:

• AMD and Intel shares were down more than 3%.
• Memory chip stocks Micron and Western Digital each fell about 4%.
• Nvidia shares continued their slide from the previous session, falling nearly 5%.
• Applied Materials and Marvell Technology both lost approximately 2.8%.

Investor Concerns Mount

Analysts attributed the sharp pullback to worries about the capital-intensive nature of the AI boom and a shifting competitive landscape. The selloff gained momentum Monday after *The Wall Street Journal* reported that Nvidia was in talks to provide around $250 billion toward a massive data-center project tied to OpenAI. The report appears to have sparked unease about the financial models underpinning the industry's rapid expansion.

Adding to market pressure are signs of China's growing capabilities in the semiconductor sector. Chinese memory chipmaker CXMT raised $8.6 billion in Asia's largest IPO of 2026, achieving a market valuation of about $487.73 billion upon its Shanghai debut, according to Reuters. This successful listing highlights the increasing competitive threat to established international players.

Market Context

The downturn marks a significant reversal for the sector. On Monday, Nvidia's 5% stock decline resulted in the AI chip leader ceding its title as the world's most valuable public company back to Apple. As a key supplier of high-bandwidth memory chips to Nvidia, SK Hynix has been a major beneficiary of the AI spending surge, making its stock particularly sensitive to shifts in investor sentiment.
