SK Hynix Plans to Double Production Capacity Over Five Years, Challenging Micron's AI Memory Dominance

According to Reuters, SK Hynix Chairman Choi Tae-won announced plans to double overall production capacity over five years at Computex Taipei recently, raising market concerns about potential challenges to U.S. chipmaker Micron Technology (MU-US) amid AI-driven memory demand.

As of Q1 2026, SK Hynix holds a 29% global market share in DRAM and 18% in NAND flash memory, according to Counterpoint Research, while maintaining a 58% share in high-bandwidth memory (HBM). Meanwhile, Micron is investing over $25 billion in capital expenditures this fiscal year to meet surging AI data center demand, significantly higher than $13.8 billion last year.
