Key Developments in the HBM Market
SK Hynix holds a significant 58% market share in the high-bandwidth memory (HBM) sector as of Q1 2026, leading competitors Samsung and Micron, each with 21%. The HBM market is projected to grow from $35 billion in 2025 to $100 billion by 2028, with prices expected to double from approximately $2 to $4-$5 per gigabyte by next year, according to DigiTimes.
Amid rising competition in the AI chip market, Nvidia controls over 80% of the sector but has seen only an 8% stock gain in 2026, lagging behind the Nasdaq-100 Technology Sector’s 35% growth. SK Hynix is leveraging its strong HBM position to boost production capacity, targeting a doubling of its wafer production by 2030. Analysts anticipate a staggering 428% increase in the company’s earnings in 2026, driven by surging demand for AI-compatible memory.
