China’s Memory Chip Push Shakes Up Market as Micron Gains and SK Hynix Loses Ground

TLDR

• China’s CXMT grabbed 10% of the DRAM market in Q2 2026, up from 4% a year ago
• Micron grew its DRAM share to 24% and NAND share to 15% in Q2 2026
• SK Hynix saw its DRAM share drop from 29% to 25% quarter over quarter
• Micron’s high-bandwidth memory capacity is fully sold out through 2026 via binding contracts
• Western Digital has 89% of revenue from enterprise and cloud, with HDD capacity allocated through 2028

China is taking a bigger slice of the global memory chip market. The latest data from Counterpoint Research shows Chinese firm CXMT now holds 10% of the DRAM market in Q2 2026, up from just 4% in the same quarter last year.

That growth is happening fast. CXMT held 8% in Q1 2026, so the jump is accelerating. Fellow Chinese chipmaker YMTC also holds 14% of the NAND flash market, up from 9% a year ago.

Micron Holds Its Ground

Micron has not been pushed aside. The U.S. company actually grew its DRAM market share to 24% in Q2, up from 22% in Q1. Its NAND share also rose, from 13% to 15%.
