China’s Yangtze Memory Technologies accounted for 14 percent of global NAND flash shipments during the April-to-June quarter of 2026, enough to put it in the global top three by volume for the first time and to push Kioxia down a spot, according to industry research reported by Tom’s Hardware and TechPowerUp.
AI demand has reshaped the flash industry. Samsung led with 25 percent of bit shipments and SK hynix followed with 22 percent, while YMTC’s 14 percent came with a 22 percent year-over-year increase in shipments. In the first quarter, Counterpoint Research put YMTC at 13 percent, roughly level with Micron and SanDisk, and the company is aiming for 15 percent of shipments by year-end.
Volume, though, is not the same as value. By revenue, YMTC still ranks fifth, behind Micron and the Kioxia it overtook on volume. Nearly all of YMTC’s output goes into consumer products: client SSDs, phone storage and memory cards, which earn far less per bit than the enterprise drives that now dominate the market. Its revenue growth is nonetheless dramatic. Counterpoint data cited by TechNode and Crypto Briefing put YMTC’s first-quarter revenue at about $2.6 billion, up nearly 445 percent year over year, which made YMTC the fastest-expanding big flash vendor.
The demand side is the AI server. Enterprise and server SSDs absorbed 48 percent of all NAND bits shipped during the quarter, compared with roughly 26 percent twelve months earlier, according to the same research. The driver is inference rather than training: training workloads rely on high-bandwidth memory close to the accelerator, while serving models demands enormous volumes of data that can be read quickly and cheaply, precisely the job that high-capacity enterprise SSDs are built for. Solidigm, SK hynix’s enterprise storage unit, saw shipments jump 40 percent quarter over quarter, a beneficiary of the same shift.
The reallocation has consequences for consumers. Fabs have limited capacity, and any wafer routed toward high-margin data center products is one that will not go into a consumer drive. Drive prices have climbed all year for this reason. TrendForce sees NAND contract prices rising another 10 to 15 percent quarter over quarter through the third quarter.
YMTC’s position is complicated by export controls. The company has been on Washington’s Entity List since late 2022, which blocks it from leading-edge Western tooling and limits how aggressively it can scale. A large share of its output is also consumed inside China, so most of its volume stays in the domestic market rather than appearing on Western store shelves. In short, YMTC now has the volume to matter in NAND, but its output is not what will bring consumer SSD prices down.
