Contract prices for both NAND and DRAM have jumped by an estimated 15-20% in the fourth quarter of 2025, according to numbers published by DigiTimes on September 17, an off-season surge the publication ties directly to AI infrastructure build-outs and supply tightness.
“Supply shortages led to aggressive procurement from cloud service providers, with high-stack 3D NAND products nearly sold out,” writes DigiTimes, adding that, “3D NAND… has attracted strong priority purchasing interest from CSP customers,” citing demand for faster read speed and larger die capacities. This is a stark difference from the normal Q4 pattern, when component prices typically drift lower.
