RETROSPECTIVE ANALYSIS — updated 2026-08-08. Compiled from the dated public sources listed at the end of this issue; all figures are quoted from those sources.
Everything that defined the 2026 memory market was set in motion in H2 2025. In July, TrendForce published the DDR4 exit timeline for Samsung (orders stopping mid-2025), Micron (EOL notice, final shipments Q1 2026) and SK hynix (orders stopping October 2025); SK hynix reportedly raised DDR4/LPDDR4X contract prices ~20% for Q3; and TrendForce revised consumer DDR4 3Q25 contract forecasts to +85–90% QoQ. In August it described a "structural shortage" in DDR4/LPDDR4. By September, DDR4 had become such a cash cow — at inverted DDR4-above-DDR5 prices — that Samsung and SK hynix reportedly delayed their phase-outs into 2026, while Taiwan’s Nanya and Winbond eyed 20–50% Q4 hikes.
In October, OpenAI’s Stargate memory partnerships with Samsung and SK hynix were reported to require up to ~40% of global DRAM output — the half-year’s defining demand headline — and TrendForce projected DDR5 profitability would surpass HBM3e in 2026. Q4 forecasts were revised repeatedly upward (general DRAM to +18–23% QoQ; server DRAM to +43–48%). In November, Dell’s COO said the company had "never witnessed costs escalating at the current pace". In December, Micron announced its exit from the Crucial consumer business, and CXMT deepened its DDR4 retrenchment while US cloud buyers courted Nanya for legacy DRAM.
Three moves defined the half-year: fab capacity pivoted decisively to HBM and high-capacity DDR5 for AI; DDR4’s planned exit collided with persistent installed-base demand, inverting its price above DDR5 at times; and the primary market’s exit doors (Crucial retail, CXMT output) started closing one by one.
H2 2025 is when decommissioned DDR4 changed from surplus to strategic. Every fleet still running Dell 13/14G or HPE Gen9/Gen10 platforms entered 2026 with a simple arithmetic: new DDR4 supply ending, prices parabolic, platforms still in service. The used, tested, documented module became the bridge — and that is the market this desk observes.
