How SK Hynix Overtook Samsung in AI Chipmaking Stakes

2026-06-23 · Source: AI Magazine · Field: Technology & Digital — Artificial Intelligence & Machine Learning, Emerging Technologies & Innovation · Depth: Novice, short

Summary

SK Hynix has surpassed Samsung Electronics to become the world's most valuable memory chipmaker, achieving a market capitalization of 2,080.4tn won (US\$1.35tn) on June 22, 2026. This milestone is primarily attributed to its strategic focus and supply of High-Bandwidth Memory (HBM) chips, crucial components for AI system builders like NVIDIA and Google. Despite a 2023 operating loss of 7.73tn won (US\$5.02bn) during a memory industry downturn, SK Hynix continued HBM investment, leading to a record 23.5tn won (US\$15.26bn) profit in 2024 as AI infrastructure spending surged. By 2025, SK Hynix held 61% of the global HBM market, significantly ahead of Samsung's 17% and Micron's 21%. HBM chips, which are vertically stacked for faster performance and lower power, are now considered core components, reshaping industry economics and giving suppliers greater pricing power. The company also plans a Nasdaq listing to broaden its investor base.

Key takeaway

For investors evaluating semiconductor portfolios, SK Hynix's success highlights the critical importance of specialized AI components like HBM. Your investment strategy should prioritize companies demonstrating foresight in niche, high-growth areas, especially those willing to invest counter-cyclically. This shift indicates that core AI infrastructure components now command significant market value and pricing power, making their suppliers indispensable. Consider the long-term implications of component specialization on market leadership and supply chain resilience.
