Market Context
DDR5 Market Trend
↑ Rising
TrendForce’s 3Q26 conventional DRAM contract forecast still holds at +13–18% QoQ; Nvidia’s Aug 27 earnings call reinforced the floor, with the CFO flagging the memory bottleneck as a growth constraint through fiscal 2028
DDR4 Spot Trend
↑ Record High
Mainstream DDR4 (1Gx8, 3200) spot has now held its $42.45 record for three-plus weeks; desktop retail DDR4 averages $7.61/GB and DDR5 $15.27/GB across tracked kits as of mid-August
HBM Availability
Bottleneck Through FY28
Nvidia told analysts the memory shortage will constrain growth at least through fiscal 2028 and is reportedly locking down multi-year supply deals; TrendForce sees combined HBM wafer input at the big three rising from 22% of DRAM capacity (end-2026) to 30% (end-2027)
Supplier Outlook
Rebound on Nvidia Guidance
Samsung (+3.3%) and SK Hynix (+5.5%) rallied Aug 27–28 after Nvidia’s print validated the shortage thesis; Goldman raised its 2027 DRAM deficit forecast to 5.9% (tightest in 15 years), even as Michael Burry has built a public short against Micron on 2028 oversupply risk

Rose as much as 3.3% on Aug 27–28 after Nvidia’s FY28 memory-shortage guidance validated the AI-memory demand thesis, clawing back part of the prior week’s hedge-fund unwind
TrendForce projects combined HBM wafer input across Samsung, SK Hynix and Micron rising from 22% of total DRAM capacity at end-2026 to 30% by end-2027

On pace to earn more profit in 2026 than across the previous 27 years combined, underscoring how central HBM has become to its earnings base

IndustryBroader DRAM & Memory News
Nvidia Earnings
Nvidia’s CFO told analysts on the Aug 27 call that the memory-supply bottleneck will constrain growth at least through fiscal 2028, and the company is reportedly locking in multi-year supply agreements with suppliers
This is the single biggest data point of the week — it converts what had been quarter-to-quarter allocation anxiety into a multi-year underwriting of the AI-memory capex cycle, and explains why Samsung and SK Hynix rallied immediately after the print.
Stock Reaction
Samsung rose as much as 3.3% and SK Hynix gained 5.5% in the two sessions after Nvidia’s earnings, reversing a meaningful share of the hedge-fund positioning unwind flagged in last week’s edition
Last week’s “smart money rotating out” narrative met an immediate rebuttal: Nvidia’s own guidance was the trigger the market needed to re-underwrite the memory-shortage thesis, at least for the two Korean majors most levered to HBM.
Shortage Forecast
Goldman Sachs raised its 2027 DRAM supply-deficit forecast to 5.9%, describing current conditions as the most severe memory shortage in 15 years
Goldman’s revision cuts against the pricing misses flagged two weeks ago — it argues the miss was a one-quarter timing issue, not evidence the shortage is easing, and puts a specific number on just how tight 2027 looks.
Bear Case
Michael Burry has built a short position against Micron, arguing AI data-center memory oversupply could emerge by 2028
Burry’s position is the most visible dissent from the shortage-through-2028 consensus building elsewhere this week via Nvidia and Goldman — worth tracking as the closest thing to an institutional bear thesis on record right now.
Contract Terms
TrendForce detail on 3Q26 server DRAM contracts: total RDIMM bit supply growing just 15–20% YoY against faster CPU shipment growth, with some builds shifting from 96GB/128GB modules to 32GB/64GB configurations, and U.S. hyperscalers with existing long-term agreements shielded from the latest round of increases
This is the mechanism behind the headline QoQ percentages — buyers without LTAs are absorbing the full price shock while LTA-protected hyperscalers are not, and some are engineering around the shortage with smaller module configs rather than paying up.
