AI infrastructure is reshaping the NAND Flash market. As AI workloads expand from large-scale model training into inference, enterprise SSDs are becoming an increasingly critical component of modern data centers. This structural shift is supporting continued growth in NAND Flash demand, while NAND manufacturers remain cautious about expanding production capacity.
According to data from ChinaFlashMarket (CFM), the global NAND Flash market continued its strong growth in the second quarter of 2026. Market revenue increased 73.1% quarter over quarter to approximately $76.78 billion, driven primarily by a combination of stronger AI-related demand, higher enterprise SSD consumption, and significant increases in NAND Flash average selling prices (ASP).
The most important feature of the current market is not simply higher shipment volume. Pricing is rising much faster than bit shipments, giving major NAND manufacturers significantly stronger pricing power.
AI Inference Is Creating a New Wave of Enterprise SSD Demand
The expansion of AI infrastructure is changing the demand structure of the storage market.
During the early stages of the AI boom, attention was heavily concentrated on GPU computing, HBM, and high-performance memory required for model training. As AI moves into large-scale inference and commercial deployment, however, storage is becoming increasingly important.
AI inference environments require large amounts of data to be continuously stored, accessed, processed, and served. This creates growing demand for high-capacity, high-performance enterprise SSDs.
At the same time, NAND manufacturers have remained relatively conservative regarding new capacity expansion. Investment priorities across the semiconductor industry continue to favor higher-value products and technologies, particularly DRAM and HBM.
This combination has created an important market imbalance:
AI-driven demand is expanding, while new NAND capacity remains limited.
As a result, NAND suppliers have been able to maintain stronger pricing power throughout Q2 2026.
NAND ASP Growth Outpaces Shipment Growth
One of the clearest signals from the Q2 market is the sharp increase in NAND Flash ASP.
For several major manufacturers, revenue growth was substantially higher than bit shipment growth. This indicates that the current NAND market recovery is being driven primarily by pricing rather than volume alone.
For buyers, this distinction matters.
A market where shipments increase gradually but ASP rises sharply can create a very different procurement environment from a traditional demand recovery. Enterprise customers, SSD manufacturers, distributors, and system integrators may face significantly higher component costs even when actual NAND consumption has not increased at the same rate.
In other words:
The NAND market is experiencing a strong price-volume combination, but price is currently doing more of the work.
Samsung Remains the World's Largest NAND Flash Supplier
Samsung maintained its position as the world's largest NAND Flash manufacturer in Q2 2026.
The company's NAND ASP increased approximately 67%–69% quarter over quarter, while NAND bit shipments reached a historical high.
The combination of record shipment volume and significantly higher ASP drove Samsung's NAND Flash revenue up 65.7% quarter over quarter.
Samsung held approximately 27.5% of the global NAND Flash market, keeping a substantial lead over its competitors.
For global buyers, Samsung's position remains particularly important because its NAND products are widely used across enterprise SSDs, client SSDs, mobile storage, and other applications.
SK hynix Benefits From Enterprise SSD Growth
SK hynix recorded one of the strongest performances among the major NAND suppliers.
Its NAND Flash revenue increased 89.1% quarter over quarter, supported by a sharp increase in enterprise SSD revenue and continued volume growth of products based on its advanced 321-layer NAND technology.
Enterprise SSD revenue more than doubled during the quarter, highlighting the growing importance of AI data centers and high-performance storage infrastructure.
SK hynix held approximately 18.5% market share, ranking second globally.
The company's performance also demonstrates an important industry trend: enterprise SSD demand is becoming one of the key drivers of NAND Flash market value.
YMTC Continues to Expand Through Domestic Adoption
Yangtze Memory Technologies Co. (YMTC) ranked third globally with approximately 15.0% market share.
YMTC's NAND Flash revenue increased 69.1% quarter over quarter.
The company's growth continues to benefit from increasing adoption among Chinese manufacturers, supported by domestic substitution trends and competitive product economics.
For the global supply chain, YMTC is becoming an increasingly important NAND Flash source to monitor, particularly for buyers evaluating alternative supply channels and China-based semiconductor sourcing.
From a sourcing perspective, the expansion of YMTC's applications is important not only because of its market share, but also because it adds another significant supplier to an industry historically dominated by a small number of major international manufacturers.
Kioxia Benefits From Higher ASP and BiCS8 Expansion
Kioxia also recorded strong growth during Q2 2026.
Its NAND Flash revenue increased 73.5% quarter over quarter, supported by substantially higher ASP and continued expansion of its advanced BiCS8 Flash technology.
BiCS8 products accounted for more than 50% of Kioxia's NAND Flash production capacity, indicating a significant transition toward its latest-generation NAND technology.
Kioxia held approximately 14.4% of the global market, ranking fourth.
Micron Records the Fastest Revenue Growth Among the Top Suppliers
Micron recorded the strongest NAND Flash revenue growth among the major suppliers during the quarter.
For its fiscal Q2 period covering March through May 2026, NAND bit shipments increased only in the mid-single-digit range quarter over quarter.
However, NAND ASP increased by more than 80%, resulting in a remarkable 99.0% quarter-over-quarter increase in NAND Flash revenue.
Micron's market share reached approximately 13.0%, placing it fifth globally.
The result provides perhaps the clearest example of how strongly pricing has influenced the current NAND market.
SanDisk Begins Recognizing QLC Revenue
SanDisk ranked sixth globally with approximately 11.7% market share.
The company began shipping QLC products and recognizing related revenue during Q2. Overall NAND Flash revenue increased 50.7% quarter over quarter.
The continued development of QLC products is particularly relevant for high-capacity storage applications, where cost per gigabyte remains an important consideration.
As AI data volumes continue to grow, the balance between performance, capacity, endurance, and cost will remain a major factor in determining which NAND technologies gain adoption across different storage segments.

What Does This Mean for NAND Flash Buyers?
For global buyers, the Q2 2026 NAND market sends a fairly clear signal:
NAND Flash is no longer simply recovering through volume. It is entering a stronger pricing environment driven by AI infrastructure and limited supply expansion.
Three factors deserve particular attention.
1. Enterprise SSD demand is becoming structurally important
AI inference and data-center expansion are increasing demand for enterprise storage. This is likely to remain an important driver of NAND consumption as AI applications move from infrastructure development toward commercial deployment.
2. NAND capacity expansion remains disciplined
Manufacturers appear unwilling to aggressively add new NAND capacity simply to chase short-term demand. This limits the amount of new supply entering the market and gives major suppliers greater control over pricing.
3. Procurement timing matters more in a rising market
When ASP increases substantially faster than shipment volume, buyers may face higher costs even without significantly increasing their NAND requirements.
For SSD manufacturers, electronics companies, system integrators, and distributors, monitoring NAND pricing and supplier availability becomes increasingly important.
