Chinese memory-chip makers continued gaining ground in the second quarter of 2026, with ChangXin Memory Technologies (CXMT) capturing 10% of global DRAM revenue, up from 4% a year earlier, and Yangtze Memory Technologies (YMTC) lifting its NAND revenue share to 14% from 9%, overtaking SanDisk, whose share fell to 11% from 12%. The combined DRAM share of Samsung Electronics, SK Hynix and Micron declined to 87% from 94%, even as Micron raised its own DRAM share to 24% from 22% and its NAND share to 15% from 13%. U.S. technology stocks rebounded broadly on Thursday as Treasury yields retreated, with the Nasdaq Composite up 1.4%, but the memory group lagged: Micron rose 0.22% to close at $958.16, SanDisk gained 0.1%, while Western Digital and Seagate fell 1.63% and 1.23% and SK Hynix’s ADR slipped 0.79%. Counterpoint Research said the share gains came during a booming market in which NAND revenue rose about 70% quarter over quarter and prices jumped roughly 55%, while artificial-intelligence demand kept DRAM supply tight. CXMT reached a more than 20 billion yuan, or about $3.0 billion, three-to-five-year DRAM supply agreement with Tencent and plans to double monthly wafer capacity from roughly 300,000 to 600,000 wafers. YMTC’s parent plans to raise about $4.9 billion through a Shanghai IPO for equipment upgrades and research. Market sources say Micron is researching a high-endurance “near-GPU NAND” concept that would let GPUs access NAND pools of several hundred gigabytes at higher bandwidth, though the work remains at the research stage and is not a mass-produced HBM or GDDR7 substitute. TrendForce expects DRAM supply to stay tight through 2027 while NAND may loosen in the second half as new capacity arrives. Polymarket traders assigned about a 29% chance Micron touches $990 by week-end and an 8% chance of a U.S. government equity stake by year-end.
