Chip Stocks Extend Declines as AI Funding Concerns Intensify

what happened

Stocktwits reports that U.S. semiconductor stocks extended their decline as investors focused on the funding needs of AI infrastructure and mounting Chinese competition in memory chips. In late Monday trading, Micron Technology (MU) fell 2.7%, SanDisk (SNDK) lost 3.3%, Intel (INTC) declined 2.5% and Advanced Micro Devices (AMD) dropped 1.7%. SanDisk had already plunged 6% in the regular session, the Nasdaq-100’s second-largest decline. The iShares Semiconductor ETF (SOXX) posted its fifth straight lower session.

Samsung Electronics and SK Hynix each fell about 5% in Seoul on Tuesday, while South Korea’s KOSPI dropped as much as 4.8%. Broadcom (AVGO) CEO Hock Tan said capital availability and its cost could become a greater obstacle to AI expansion than shortages of chips or electricity. According to CNBC, he also stressed that investors would eventually seek returns on the spending. Intel CEO Lip-Bu Tan echoed the concerns, citing higher borrowing costs and uncertainty over the returns from AI infrastructure investment.

Memory-chip makers faced another challenge from China’s ChangXin Memory Technologies (CXMT). The company is advancing a 4F2 DRAM architecture and plans to launch a server-memory product using the technology by the end of 2026. On Stocktwits, sentiment toward MU shifted from “bullish” to “neutral,” while AMD moved from “neutral” to “bearish” and DRAM from “bullish” to “bearish.”

why it matters

The sector is facing two linked concerns: more expensive funding for large AI projects and stronger competition in memory chips from CXMT. Investors are therefore focusing more closely on spending, returns and manufacturers’ technology roadmaps.
