China’s Yangtze Memory Technologies Co. climbs into the top three global NAND producers, intensifying industry competition and posing a threat to Micron’s robust profit margins amid rising Chinese capacity and enterprise demand shifts.
Micron Technology shares rose on Thursday after fresh market data showed China’s Yangtze Memory Technologies Co. had moved into the top tier of the global NAND flash market. Micron closed up 6.35% at $969.15, extending a three-day recovery as investors returned to AI-linked memory stocks.
According to Counterpoint Research, YMTC took 14% of worldwide NAND shipments in the second quarter of 2026, enough to place it third by unit volume behind Samsung at 25% and SK hynix at 22%. The company’s shipment growth was 22% year on year, helped by stronger consumer demand and by major rivals concentrating more of their capacity on higher-margin enterprise products.
That shift matters because enterprise SSDs, which are widely used in servers, now account for 48% of NAND bit consumption, up sharply from 26% a year earlier. Tom’s Hardware reported that YMTC remains fifth by revenue because most of its output still serves consumer devices and it is constrained by U.S. trade restrictions that limit its access to Western enterprise markets. Even so, the company has mass-produced 267-layer NAND, is developing chips with more than 300 layers and is expanding manufacturing in Wuhan, with two more fabs planned.
Micron, meanwhile, has been leaning on its own strength in premium memory. The company said its most recent quarter produced record revenue, gross margin and adjusted free cash flow, and it guided for further growth in the current quarter. Analysts cited by the market remain largely constructive on the stock, but the latest NAND data also highlights a risk: if Chinese capacity keeps rising, price pressure could spread beyond consumer memory and eventually weigh on the enterprise segment that has so far protected Micron’s margins.
