DRAM / DDR4 / DDR5
Spot demand for DDR5 and DDR4 has softened at the buyer level, yet supplier quote discipline is holding prices elevated — a dynamic TrendForce flagged as of September 2 and one that typically precedes a formal contract price step-up. That step-up may already be priced in: TrendForce, via Gate News, has raised its Q3 2026 PC DRAM contract price forecast to +18–23% quarter-on-quarter, while revising mobile DRAM down to +8–13%. Procurement teams should not read flat spot prints as a signal to wait. Per Startup Fortune, Samsung, SK Hynix, and Micron have reportedly sold out their 2027 allocation, which materially limits spot optionality for buyers who have not already secured forward agreements.

HBM & AI Supply Dynamics
HBM capacity is reshaping the conventional DRAM landscape. Micron is reportedly on track to add 60K HBM wafers per month, targeting 100K by year-end (TrendForce, Electronic Times), while Samsung has doubled its HBM market share to 33%, narrowing SK Hynix's lead (Seoul Economic Daily). Every wafer start committed to HBM is a wafer not producing DDR5, which underpins supplier leverage on standard module pricing. Startup Fortune attributes Micron's price gains directly to this AI-datacenter absorption effect.
NAND / SSD
NAND is the more acute near-term story. CHOSUNBIZ reports the NAND market has surged 70%, led by Samsung and SK Hynix. Phison's CEO has publicly warned that the global NAND flash shortage will persist through 2027 (Streamline), a controller-maker vantage point that carries operational weight. Enterprise SSD revenue is on pace to roughly double in Q2 as both demand and prices rise (Communications Today). The YMTC wildcard bears watching: its NAND share gains introduce a degree of supply-side uncertainty for Samsung and SK Hynix pricing discipline (The Investor), though near-term it does not offset the shortage signal.
Procurement guidance: Index prices are calm today, but forward indicators — sold-out 2027 allocations, a +18–23% PC DRAM forecast, and a multi-supplier NAND shortage call extending through 2027 — all argue against deferring volume commitments. Engage suppliers on H1 2027 pricing now.
