Semiconductor stocks retreat over worries about memory costs - Yahoo Finance

On June 26, 2026, semiconductor stocks retreated amid growing concerns over rising memory costs, which are expected to impact broader tech margins and demand. Companies such as Micron Technology (MU),... Read original →

Soaring memory costs are triggering a structural reshuffle across the semiconductor value chain. Surging AI server demand for HBM and DDR5 intensifies competition for EUV capacity at sub-3nm nodes, forcing logic and memory chips into direct wafer allocation conflicts and inflating foundry costs. Tightening U.S.-Japan-Netherlands export controls delay equipment access for memory makers in Taiwan, China, and mainland China, further constraining supply elasticity. Under margin pressure, NVIDIA and AMD may accelerate in-house memory controller development to reduce DRAM dependency, while Micron locks in cloud hyperscaler contracts via long-term agreements. Over the next 12–24 months, winners will bifurcate: vertically integrated IDMs like Intel and memory suppliers deeply embedded in AI infrastructure. A prolonged OpenAI IPO delay would temper AI capex optimism, compelling chipmakers to shift from performance-first to cost-optimized design paradigms.
