Semiconductor stocks retreat over worries about memory costs - Yahoo Finance UK

On June 26, 2026, semiconductor stocks retreated amid growing concerns over rising memory costs. Key players such as Micron Technology (MU), SanDisk (SNDK), and Western Digital (WDC) saw significant d... Read original →

Soaring memory costs are triggering a structural reshuffle across the semiconductor value chain. Aggressive adoption of HBM and DDR5 in AI servers, combined with EUV yield constraints at 3nm, has intensified competition for shared fab capacity between logic and memory. Apple’s and Microsoft’s price hikes signal that consumer demand elasticity is hitting a wall—threatening the rollout of edge AI devices. Micron’s long-term contracts shield its margins but externalize volatility onto weaker rivals, squeezing their cash flow. Geopolitically, tightening U.S.-led export controls on lithography tools force foundries in Taiwan, China and mainland China to rely on refurbished or domestic alternatives, yet advanced-node bottlenecks persist. Over the next 12–24 months, expect brutal consolidation: memory players without process differentiation will be acquired, while firms mastering chiplet integration and near-memory computing will set new pricing norms. OpenAI’s IPO delay reflects broader investor skepticism on AI hardware ROI—a reckoning where only manufacturing efficiency and real-world demand sustain competitive advantage.
