TrendForce’s latest research indicates that demand for NAND Flash remained strong in November 2025, with Artificial Intelligence applications and solid enterprise SSD orders cited as the primary demand drivers. The report highlights sustained customer interest across segments, which underpinned continued ordering activity throughout the month. November’s demand dynamics reflected a market environment where new workloads and storage procurement kept consumption elevated relative to prior periods.
Suppliers responded by reallocating capacity toward higher-margin enterprise and premium products while accelerating the phase-out of old-node capacity. This strategic shift concentrated manufacturing resources on newer, more profitable product lines and reduced available output for mainstream and legacy wafers. TrendForce describes this capacity rebalancing as an intentional prioritization of premium segments that narrowed the supply available to other density and mainstream categories.
The combined effect of robust demand and supplier capacity focus led to a further tightening of wafer supply in November 2025 and a sharp rise in contract prices for mainstream wafers. TrendForce reports that monthly average price increases varied from 20% to over 60% across all product categories, and that the price surge quickly expanded to all density segments. The research frames the November movement as broad and rapid, affecting multiple product tiers as supply constraints and shifting capacity allocations intersected with stronger order flow.
