YMTC breaks into the top three NAND makers for the first time as AI servers swallow 48% of all flash — Chinese vendor has 14% share, according to research

Yangtze Memory Technologies (YMTC) achieved a significant milestone in the second quarter of 2026 by becoming the third largest NAND flash manufacturer globally, surpassing Kioxia, according to Counterpoint Research's Memory & Storage Tracker. Samsung led with 25% share, followed by SK hynix at 22%, and Micron completed the top five with 16%.

The Chinese vendor's climb to the top three occurred amid a surge in enterprise solid-state drives (SSDs) consuming 48% of all NAND bits shipped worldwide, a fivefold increase from the previous year. AI data centers are consuming the world's memory and storage supply, with enterprise SSDs swallowing 48% of the NAND bits this quarter, up from 26% a year earlier.

While YMTC sits fifth in terms of revenue, its consumer-focused products come at a fraction of the price paid by hyperscaler buyers for enterprise SSDs with KV caches and inference datasets. The company is limited in terms of addressable market due to being on the U.S. Entity List since December 2022, which prevents it from achieving Western server qualification.

The consumer channel vacancy is an area where YMTC is well-positioned to dominate, with the company growing shipments by 22% year over year and 5% sequentially. They mass-produce 267-layer 3D NAND on their Xtacking architecture, with development underway for devices exceeding 300 layers. The company's third Wuhan fab has cleared Beijing's 50% domestic-tooling threshold and is set to commence production later this year, with two additional fabs planned.

Counterpoint expects enterprise SSDs to account for half of all NAND bits by year-end, despite the consumer pool YMTC dominates shrinking as a share of the total market. YMTC plans to shift its focus towards enterprise SSDs in the second half, backed by growing avenues for capital support.
