CXMT hits 10% DRAM share, ending the Big Three's market dominance

China’s ChangXin Memory Technologies (CXMT) is rapidly gaining ground on global DRAM leaders. According to Q2 2026 data from Counterpoint Research, CXMT’s revenue share jumped to 10% from 4% a year earlier. This growth established the company as the world's fourth-largest DRAM manufacturer.

The combined market share of industry leaders Samsung, SK Hynix, and Micron fell from 94% to 87% over the past year. Samsung Electronics maintained the top position with a 38-39% market share. SK Hynix saw its share decline to 25-26%, while Micron held steady at approximately 24-25%.

CXMT is leveraging expanded production capacity to meet surging domestic demand in China. These factors are intensifying competition for the traditional dominant players in the memory chip sector.
