Memory Sector Primer: HBM, NAND, and the 2026 Up-Cycle

HBM is sold out through 2027 and SK Hynix posted 49 percent operating margins on it. NAND is undersupplied for the first time in a decade, with KV-cache offloading and 122 TB QLC drives adding a new demand tier that didn’t exist 18 months ago. Macronix becomes the only credible sub-32GB MLC supplier in the world after Samsung exits in October 2025. This is a multi-year up-cycle, not a quarter-to-quarter print.
