Micron's HBM and server-memory scarcity is backed by customer commitments beyond its earlier sold-out 2026 capacity. Per management and sell-side reports, more than about 75% of fiscal 2027 shipments are allocated or contracted, supply may not rebalance through 2028, and 2027 HBM prices have risen significantly. Strategic agreements extend through 2030; a later supply glut or faster Chinese competition could erode margins. x.com
