Market Context
DDR5 / Mobile Trend
■ Consolidating
TrendForce (Sep 16) reports DDR5 spot inquiries slowing and prices in interval consolidation as suppliers loosen quotes; DDR5 is still up nearly 6x year over year (DDR5 16Gb die $55.60, +480% YoY), but the summer’s vertical run has paused. Mobile LPDDR5X contract stays firm heading into Q4.
DDR4 Spot Trend
↑ 1Gx8 Record, 2Gx8 Soft
DDR4 1Gx8 3200 hit a fresh $45.79 tracker high (DRAMeXchange Daily Express, Sep 16) on persistent legacy tightness, while 2Gx8 branded chips saw pronounced downward corrections on weak consumer demand — the split shows the shortage has turned node-specific.
HBM Capacity
HBM4 Race, Still Sold Out
SK Hynix completed HBM4 development (40% better power efficiency, 10 Gbps) and Micron is doubling HBM capacity toward ~100k wafers/month for Nvidia’s Vera Rubin; 2026 output stays sold out even as the front shifts from HBM3E volume to HBM4 qualification.
Supplier Sentiment
■ Two-Sided
Supply partners are advising buyers to plan for 10–20% monthly DRAM increases through year-end, yet softer-than-expected Samsung/SK Hynix pricing and SK Hynix’s slower HBM4 shipments last quarter have revived “is demand cooling?” questions ahead of Micron’s Sept 30 print.

Spot PricesDRAM SKU Pricing — Week of Sep 14
DDR5 · 16Gb · 4800/5600 MT/s
$27.80/GB ($55.60)
■ Rebased
Prior (mis-stated): $4.98 chip
Rebased to the sourced DDR5 16Gb 4800/5600 die spot of $55.60 (Sep 18; +480% YoY, +7.31% over 30 days) — i.e. $27.80/GB. The prior $4.98 chip figure was ~11x too low; this puts DDR5 on the same chip-price-over-GB basis as the DDR4 cards. WoW spot is roughly flat as inquiries consolidate.
DDR5 · 32Gb · 6400 MT/s
$28.00/GB ($112.00)
■ Rebased (est.)
Prior (mis-stated): $10.43 chip
DM estimate: rebased to ~$28.00/GB ($112 per 32Gb die), anchored to the sourced DDR5 16Gb die spot ($55.60, Sep 18) at a small density premium; no discrete 32Gb die print this week. Corrects the prior $10.43 chip figure, which was ~11x too low.
DDR4 · 8Gb (1Gx8) · 3200 MT/s
$45.54/GB ($45.54)
▲ New Record
Prior week: $44.54
TrendForce mainstream DDR4 1Gx8 rose 0.47% to $45.54 (Sep 15); the DRAMeXchange Daily Express close hit $45.786 on Sep 16, a record — legacy 8Gb tightness persists even as broader spot demand cools.
DDR4 · 16Gb (2Gx8) · 3200 MT/s
$46.01/GB ($92.02)
■ Held, 2Gx8 Softening
Prior: $46.01
TrendForce (Sep 16) reports 2Gx8 branded DDR4 seeing pronounced downward corrections on weak consumer demand; no discrete spot figure was published, so the $92.02 chip value is held pending a tracked print — the direction is lower.
LPDDR5X · Mobile · Q3 Contract
~$26.50/GB
■ Q3 Contract Set
Prior: ~$26.50/GB
Q3 mobile contract carried forward — no fresh quarterly print this week. Supply partners are advising OEMs to plan for 10–20% monthly DRAM increases through year-end, pointing to a firmer Q4 reset even as spot cools.
HBM4 · 36GB 12-High Stack
~$500/stack
■ Allocation Only
2026–2027 output committed
No merchant spot price. SK Hynix completed HBM4 development (40% better power efficiency, 10 Gbps); Micron is shipping 11 Gbps HBM4 samples and doubling capacity toward ~100k wafers/month by end-2026 for Nvidia’s Vera Rubin.

Targeting roughly 50% more memory production capacity in 2026, but its and SK Hynix’s softer-than-expected pricing this cycle has some analysts asking whether AI memory demand is decelerating at the margin
Now trails both SK Hynix and Micron in HBM share estimates as the 2026 battle pivots to HBM4 — Micron has overtaken Samsung for the No. 2 position

IndustryBroader DRAM & Memory News
Pricing
TrendForce’s September 16 spot update shows the market cooling — DDR5 inquiries slowing and 2Gx8 DDR4 retreating — even as DDR4 1Gx8 set a fresh $45.79 record
The first real demand-side softening after months of near-vertical gains. It separates near-term spot (cooling on weak consumer demand) from structural contract (still rising), which reads as a mid-cycle consolidation rather than a top while HBM cannibalization of wafer supply persists.
HBM / AI Demand
SK Hynix completed HBM4 (40% better power efficiency, 10 Gbps) and Micron is shipping 11 Gbps HBM4 samples while doubling HBM capacity for Nvidia’s Vera Rubin
The competitive front has moved from HBM3E volume to HBM4 qualification. Whoever qualifies first for Rubin captures the richest 2027 allocation, so the development milestones this week matter more for 2027 share than any single spot print does for 2026.
Contract Outlook
Supply partners are advising buyers to plan for 10–20% monthly DRAM price increases through year-end; TrendForce sees prices rising through Q4 and analysts project up to ~130% for full-year 2026
The gap between cooling spot and rising contract is the tell of this week. Spot is a leading but noisy indicator; contract is where AI-driven scarcity actually gets paid, and every signal there still points up into 2027.
Demand Signal
Softer-than-expected Samsung and SK Hynix pricing, plus SK Hynix’s slower HBM4 shipments last quarter, have revived questions about whether AI memory demand is decelerating
These are the first credible bear datapoints of the cycle. They set up Micron’s September 30 print as the swing factor for whether the supercycle narrative holds into 2027 or the market re-rates the whole complex lower on a demand wobble.
Structural Supply
Micron expects 2026 HBM effectively sold out with an ~$8B annualized HBM run-rate, while the industry’s roughly 3-to-1 HBM-to-DDR5 wafer conversion keeps cannibalizing standard DRAM
The structural mechanism behind the whole shortage in one ratio: every incremental HBM wafer removes about 3x the standard-DRAM bits, which is why DDR4 and DDR5 stay tight even in a week when end-demand visibly softens.
