Three Major Memory Makers' 2027 Capacity Sold Out—Could Become the Industry's Tightest Year Ever

The AI wave continues to push memory demand, and the global memory market is entering an unprecedented structural shortage cycle. Industry insiders reveal that Samsung Electronics (005930KS), Micron Technology (MU-US), and SK Hynix (000660KS) have already fully allocated their 2027 annual production capacity for DRAM and High Bandwidth Memory (HBM), covering major long-term agreement customers and some mid-to-small buyers.

Not only has DRAM supply been pre-booked, but Samsung, Micron, and SanDisk have also nearly sold out their entire 2027 NAND Flash production capacity. Kioxia and SK Hynix are expected to complete capacity allocation by the end of August 2026.

Market players warn that buyers who haven’t secured capacity in advance may face a 'no stock available' situation in 2027. Meanwhile, the procurement priority of cloud service providers (CSPs) and major AI firms continues to squeeze memory supply for consumer electronics such as smartphones and PCs.

This early sell-out of memory capacity confirms SK Group’s earlier market warning that 2027 could become the year with the most severe supply-demand imbalance in memory industry history.

SK Group Chairman Choi Tae-won stated that AI semiconductor demand in 2027 is expected to grow 60% to 100% compared to 2026, with overall storage demand potentially increasing by 50% to 60%. The supply-demand gap is likely to widen further.

AI Demand Driving Memory Capacity Allocation

The core driver behind this memory supply crunch is the rapid expansion of AI infrastructure. Major memory manufacturers have recently signed 3- to 5-year long-term supply agreements (LTAs) with key customers, shifting the memory market away from traditional cyclical patterns toward a long-term supply model dominated by suppliers.

Axial Plus (3260-TW) Chairman Chen Li-pai stated that the 2027 production capacity of the three major memory makers—Samsung, Micron, and SK Hynix—is already sold out, with HBM and AI server-related applications accounting for about 70% of DRAM capacity. With total capacity limited, manufacturers are prioritizing cloud service providers and AI enterprises, reducing DRAM allocations available to smartphone and PC makers.

Industry estimates suggest that the actual capacity memory makers can provide typically meets only 60% to 70% of buyers’ original demand targets. As a result, smartphone and PC makers are expected to receive significantly less DRAM allocation in 2027 compared to 2026.

NAND Supply-Demand Outlook Remains Uncertain—Enterprise Storage Demand to Support Market

Compared to the DRAM market, which is highly concentrated among Samsung, Micron, and SK Hynix, the NAND Flash market has more suppliers, giving buyers some bargaining power. Therefore, market views on the 2027 NAND supply-demand outlook remain divided.

Some market analysts believe that as new capacity comes online and consumer demand remains weak, the NAND market could gradually ease in the second half of 2027, increasing price pressure.

However, industry insiders remain cautious, arguing that enterprise SSD demand will remain strong, and enterprise storage demand is expected to support the NAND market, potentially extending supply tightness into 2028. Thus, the impact of manufacturers’ capacity expansion should not be overly optimistic.

Shift in Memory Procurement Model—Securing Capacity Early Becomes the New Norm

With memory supply remaining tight, the procurement model is undergoing structural changes. Supply chain sources indicate that due to the ongoing 2026 capacity shortage, multiple cloud service providers and brand manufacturers have begun competing early for future capacity, completing transactions through manufacturers’ deposit-based prepayment models.

Current capacity allocation now includes not only large long-term contract customers but also some mid-sized buyers who secured 2026 supply quotas but may not be offered long-term contracts by manufacturers. Each memory manufacturer will notify customers of their allocated capacity based on internal coordination.

Industry insiders note that July to August is a critical window for memory capacity allocation, but some companies lack relevant information, primarily because market participants fear that public disclosure could attract more buyers to compete for limited capacity.

Price Increases May Moderate—High-Price Environment Could Become the Norm

Although 2027 memory supply will remain tight, price trends may not fully replicate 2026’s rapid surge. The industry widely believes that since major capacity has already been allocated, final DRAM and NAND prices will only be confirmed closer to actual shipment dates. Thus, 2027 price increases are expected to be more moderate compared to 2026’s sharp rise.

However, a 'high-price normalization' could become the new norm in the memory market. With memory manufacturers controlling capacity allocation, suppliers are expected to maintain strong pricing power, and overall supply tightness and end-user cost pressures are unlikely to ease significantly in the short term.

For manufacturers that haven’t locked in capacity, future procurement risks include higher prices or even supply shortages. The 2027 memory market competition will focus not just on price, but on whether sufficient capacity can be secured.
