ByteWatch Market Digest — 2026-08-03
Spot indexes were flat across both categories today — DDR5 holding at 110.6 and SSD at 101.2 — with no significant SKU-level price moves detected. The calm on the surface, however, contrasts sharply with the structural forces building beneath it: AI-driven demand is tightening DRAM supply conditions into 2027, while NAND is showing early signs of a ceiling that may eventually pull SSD pricing lower.

DRAM / DDR5
AI infrastructure buildout continues to squeeze conventional DRAM supply. Korea JoongAng Daily reports that AI demand has pushed DRAM prices to record highs, with PC memory costs rising alongside HBM. Major hyperscalers are actively negotiating with suppliers: SK Hynix notes that big tech is pressing for price stability, a signal that buyers at scale are worried about further upside. Both Samsung and SK Hynix are responding by expanding binding long-term supply agreements with module makers, locking in allocation and reducing spot availability. The supply picture into 2027 looks acute: Apacer's CEO warns that DRAM chip supply to module makers could fall more than 70% year-on-year in 2027, while TrendForce separately projects DRAM supply remaining tight throughout that period. Procurement teams without forward contracts should treat current pricing as a floor, not a ceiling.

NAND / SSD
The SSD index is steady, but leading indicators are less constructive. South Korea's NAND export unit values fell for the first time in nearly ten months, a meaningful divergence from still-firm SSD end-market pricing. TrendForce forecasts easing NAND supply conditions in 2027, and analysts cited by Gate News point to a looming NAND flash price decline that has already weighed on Samsung and SK Hynix equity valuations. SSD buyers are not yet seeing relief at the SKU level, but the upstream signal warrants monitoring before committing to large forward purchases.

HBM (Context for DRAM Allocation)
The HBM competitive landscape is shifting in ways relevant to conventional DRAM supply. UBS forecasts Samsung overtaking SK Hynix in HBM market share at 41% next year, driven by its HBM4 push. The Korea Herald and Aju Press both note the race is intensifying, with retail investors reacting to reversal forecasts. Greater HBM production at both suppliers means continued diversion of wafer capacity away from standard DRAM — a structural headwind for DDR5 module availability that aligns with Apacer's supply warning above.
