NAND and DRAM prices surge by up to 20% — contract price increases driven by AI demands and tight supply

Contract prices for NAND and DRAM have surged by 15-20% in Q4 2025 due to AI infrastructure demands and supply shortages. Cloud service providers are aggressively procuring high-stack 3D NAND products, leading to nearly sold-out stocks. TrendForce notes a 10% NAND price increase by SanDisk and Micron's suspension of price quotations to address shortages. Samsung's V9 NAND for 2026 is in high demand, with cloud customers securing capacity early. The shift in demand could impact consumer prices, especially for legacy DRAM types and NVMe drives. Phison's record revenue indicates strong non-consumer demand and closer ties with NAND makers.
