When will DRAM/NAND memory contract prices, which have risen sharply since 2025 due to AI data center and HBM demand, begin to decline on a quarter-over-quarter basis?

Current Market Dynamics & Decelerating Momentum As of mid-August 2026, memory contract prices continue to rise, but sequential momentum is decelerating sharply. TrendForce data shows conventional DRAM price growth collapsing from +90–95% QoQ in 1Q26 and +58–63% in 2Q26 to a forecasted +13–18% in 3Q26 trendforce.com. For 4Q26, expectations have narrowed further, with PC DRAM projected at just +3–8% kucoin.com. However, July and August 2026 are best described as a buyer-seller "stalemate" characterized by consolidating gains rather than outright declines trendforce.com. A negative print in 2026 is highly unlikely, pushing the viable window for a first decline into 2027.

The Crucial Asymmetry: NAND vs. DRAM The resolution hinges on whichever benchmark turns first, and the market consensus points overwhelmingly to NAND. While DRAM supply remains heavily constrained by AI data center needs, NAND is highly exposed to weakening consumer electronics demand. TrendForce explicitly projects that the NAND supply-demand balance (currently a 4–5% deficit) will shift to a surplus in the second half of 2027 as higher-layer migration and new fab capacity come online 3 sources. This projected 2H27 shift creates the strongest modal case for the first negative quarter-over-quarter print, clustering baseline expectations around Q4 2027.

Early 2027 Downside Risks An earlier decline—landing in the first half of 2027—remains a realistic left tail. Spot prices typically lead contract prices by one to two quarters, and cracks are already visible: spot prices for DDR4/DDR5 fell in early 2026, and monthly PC DRAM contract prices briefly flatlined 2 sources. Downstream cost tolerance has largely hit its limit amid severe consumer demand destruction in PCs and smartphones trendforce.com. If this consumer weakness swamps AI-server strength during the historically weak Q1 2027 period, a blended segment index could slip into negative territory ahead of the broader 2H27 supply shift, establishing our 10th percentile estimate around April 2027 and the 25th percentile by July 2027.

Structural Shortages and the Right Tail (2028+) Conversely, a robust right tail into 2028 and 2029 is justified by unprecedented structural constraints in DRAM. High-bandwidth memory (HBM) wafer production cannibalizes conventional DDR5 capacity at roughly a 3:1 ratio useluminix.com, structurally starving the broader market. Industry leaders, including the CEOs of Micron and SK Hynix, warn that severe tightness will persist well beyond 2027, with some seeing demand outpacing capacity past 2030 3 sources. Furthermore, suppliers are locking in customers with take-or-pay long-term agreements (LTAs) with strict price floors korea-stock-guide.com. If these LTAs hold and AI capital expenditures continue unabated, it could artificially support contract price indices even as pure capacity catches up. Evaluating these dynamics alongside expectations for future AI hardware capital expenditures and sustained hyperscaler infrastructure investments slightly pulls in our longest-term upper-bound estimates, placing our 75th percentile at July 2028 and the 90th percentile at April 2029.

Synthesis The median estimate centers on October 2027, aligning directly with the expected downstream impact of TrendForce's projected 2H27 NAND market surplus trendforce.com while maintaining our core expectation for a late 2027 decline. Modest probability is assigned to mid-2027 to account for seasonal vulnerability and early consumer demand collapse. A heavy right tail extending into 2028 and 2029 reflects the highly inelastic nature of AI-driven demand, HBM capacity cannibalization, and the persistent industry trend of forecasting severe shortages, appropriately bounded by the long-term trajectories of hyperscaler investments.
