ByteWatch Market Digest — 2026-07-29
Spot indexes are flat on the day — DDR5 at 111.1 and SSD at 99.3 — but the news flow beneath that surface calm points to a tightening supply picture in DRAM and a NAND market grinding through a prolonged plateau, with structural shifts among major producers that procurement teams should track closely heading into H2.

DRAM & DDR5: Allocation Pressure Building
The clearest near-term signal is that mainstream DRAM is moving onto allocation. A Q2 2026 industry update notes that memory is going on allocation as AI-driven power demand reshapes fab priorities, with HBM consuming an increasing share of leading-edge DRAM wafer capacity. SK Hynix is accelerating that shift, ramping HBM4 in H2 to sustain a record 76.3% gross margin, meaning less capacity remains available for commodity DDR5. Meanwhile, Samsung is revamping a 20-year-old cleanroom to expand DRAM output, though near-term relief from that retrofit is unlikely. On the demand side, SK Hynix reports that hyperscalers are pressing for long-term pricing agreements to smooth out memory cost volatility — a dynamic that could reduce spot availability for buyers without contract positions. Morgan Stanley has flagged that memory prices may peak in Q4 as the AI storage surge approaches an inflection point, but that does not imply near-term softness for standard DDR5.

NAND & SSD: Plateau, Not Relief
The SSD index at 99.3 suggests relative stability, but the underlying supply picture remains constrained. Digitimes reports that the NAND price rally has entered a plateau as supply stays tight despite some weakening in spot demand. SemiMedia's analysis goes further, suggesting the NAND flash shortage may persist through early 2027 before supply recovers. PC Guide notes that SSD prices are not expected to meaningfully settle until supply outpaces demand — likely sometime next year. Procurement guidance on managing through this environment is available via TechTarget's overview of SSD and memory price-increase mitigation strategies.

Competitive Landscape: CXMT Watch
Chinese DRAM maker CXMT is directing IPO proceeds toward filling the DRAM market segment that Korean producers have vacated as they concentrate on HBM. This is a medium-term development to monitor; it does not affect today's pricing but is relevant to sourcing diversification planning for 2027 procurement cycles.
