DRAM: Record Pricing, but Rate of Gain Is Compressing
DRAM contract prices hit a new record in October, confirmed by multiple sources, with AI server procurement — particularly for HBM — cited as the primary driver. BusinessKorea and Chosunbiz both report the record, while Market Pulse Scope notes that quarterly contract price gains have slowed to the 10–15% range even as supplier inventories have fallen to approximately two weeks of supply — a tight but stabilizing picture. TrendForce continues to forecast rising DRAM contract prices into Q3 2027. Our DDR5 index reflects this firmness, holding at 118.9 with no 24-hour movement — prices are elevated but not actively accelerating at the spot level today.
Samsung is a focal point: TrendForce reports HBM4 sales have tripled, DS division margins have reached 72%, and ten long-term agreements have been signed. Separately, The Asia Business Daily notes Chinese hyperscalers are seeking 10-year DRAM supply commitments, adding structural long-term demand pressure.
NAND/SSD: Rally Stalling After 21 Months
The NAND picture is more mixed. Kioxia has publicly warned that flash memory price increases are slowing following an outlook miss — Bloomberg Law has the detail. This aligns with our SSD index sitting at 97.3, effectively at baseline, with no movement in the past 24 hours. Chosunbiz frames the NAND rally as stalling after 21 months of gains. One data point running counter to this trend: HTX Insights reports 256GB TLC SSD contract prices are up 303% year-on-year, with SK Hynix NAND capacity fully booked through year-end — though this figure reflects the cumulative run-up rather than current momentum.
Procurement Implications
AI infrastructure demand is structurally separating HBM and high-density DRAM pricing from the broader commodity market. For standard DDR5 procurement, prices are firm but the pace of quarterly increases may be moderating. PPM Equity and SiliconANGLE both raise the question of whether AI demand is genuinely dampening the traditional memory cycle — worth monitoring for longer-horizon contract planning. On the NAND side, the stall in price momentum may offer a brief window of relative stability for SSD procurement, though low supplier inventory buffers remain a risk.
