The synchronized pullback in Micron, SanDisk, and Western Digital isn’t mere profit-taking—it reveals fragility beneath the AI memory bubble. Technically, HBM4 and CXL interconnect standards remain immature, prompting server OEMs to adopt cautious inventory policies and front-load high-end DRAM demand. On compliance, escalating U.S. export controls compel these firms to shift capacity to Malaysia and India, inflating capex and yield risks. Samsung and SK Hynix are exploiting this window to fast-track HBM3E qualifications, aiming to capture AI accelerator socket share during U.S. vendors’ ramp delays. Over the next 12–24 months, a brutal shakeout looms: players lacking advanced packaging will be marginalized, while those with TSV and CoWoS integration—like Micron—will likely command pricing power as AI inference scales. This correction marks not an end, but the onset of structural divergence.
