China's YMTC has become the world's third-largest NAND flash manufacturer by shipments, according to Counterpoint Research's Memory and Storage Tracker for the second quarter of 2026. Samsung led the market with a 25% shipment share, followed by SK hynix at 22% (boosted by its subsidiary Solidigm, which grew bit shipments 40% quarter-over-quarter). YMTC took 14% of global shipments, marking its first appearance in the global top three. Sources differ slightly on exactly who YMTC displaced: Wccftech and Tom's Hardware describe it as narrowly edging out Kioxia, while TechPowerUp reports YMTC surpassed Micron, Kioxia, and Sandisk in shipment share; Tom's Hardware separately notes Micron rounded out the top five shippers.
YMTC's shipments grew 22% year-over-year and 5% quarter-over-quarter, driven by mass production of 267-layer 3D NAND built on its Xtacking architecture (Xtacking 4.0, per TechPowerUp), with development of 300-plus-layer technology underway. Despite the shipment gains, YMTC ranked only fifth in revenue, behind Micron and Kioxia, because its output remains concentrated in lower-priced consumer products rather than high-margin enterprise SSDs (eSSDs). TechPowerUp notes YMTC has been expanding beyond China, with Lenovo shipping YMTC-based SSDs in laptops sold to German customers, and reports that Apple is considering adding YMTC to its supplier list.
The quarter's broader story is a market-wide shift toward enterprise storage: eSSDs made up 48% of all NAND bits shipped, up from 26% a year earlier, and Counterpoint expects eSSDs to exceed half of all NAND bits by year-end. Tom's Hardware reports industry revenue grew fivefold year-over-year and that NAND contract prices rose roughly 75% in the quarter alone. Samsung's shipment share has fallen from 32% in Q2 2024 to 25% as it favors higher-margin DRAM production over NAND. Kioxia, meanwhile, has its entire 2026 production already sold out, largely to enterprise customers, sending more than 30% of its bits into servers, though slower growth cost it the number-three spot it held the previous quarter.
Tom's Hardware notes that YMTC has been on the U.S. Entity List since December 2022, which blocks it from achieving Western server qualification and limits its addressable market largely to China's domestic channel and consumer demand left uncontested by larger rivals. According to Counterpoint, as cited by Tom's Hardware, YMTC plans to shift its product mix toward eSSDs in the second half of the year, supported by what the firm described as growing avenues for capital support, though this depends on reaching server customers it currently cannot access outside China.
YMTC's capacity expansion underpins its ambitions. The company currently operates roughly 200,000 wafers per month across its first two Wuhan fabs, according to Wccftech. A third fab, designed for 100,000 wafers per month, has cleared Beijing's 50% domestic-tooling threshold and is expected to begin production later this year, per Tom's Hardware, with two additional 50,000-wafer-per-month fabs planned. Once complete, Wccftech reports, total capacity could reach 400,000 wafers per month, approaching Samsung's estimated global NAND capacity of 390,000 to 450,000 wafers per month, split between its Xi'an, China facility (140,000-150,000 wafers per month) and its South Korean plants (250,000-300,000 wafers per month).
Counterpoint's analysis, cited by Wccftech, suggests that as servers absorb an ever-larger share of NAND bits, profitability through 2027 will hinge less on total shipment volume and more on which companies ship the right product mix—a challenge for YMTC given its current reliance on consumer-grade output.
