YMTC NAND market share climbs to 13% as global competition intensifies

Yangtze Memory Technologies Corporation (YMTC) has increased its global NAND flash memory market share from 8% in the same period in 2025 to 13%. Major Korean players such as Samsung and SK Hynix said that the pace of Chinese memory chipmakers’ catch-up has exceeded expectations. According to the latest report from market research firm Counterpoint Research, YMTC has become the fastest-growing company in the global NAND market. Korean industry insiders believe that its rapid expansion in both technology and production capacity is directly threatening the market positions of Samsung and SK Hynix. Public data shows that Samsung ranks first in the global NAND market with a 29% revenue share, followed by SK Hynix at 18%, while YMTC ranks fourth. YMTC has recorded double-digit growth for three consecutive quarters, with revenue reaching $2.6 billion in the first quarter of 2026, up nearly 445% year-on-year. [ Kuai Technology , in Chinese]
