South Korea — SK Hynix has overtaken Samsung Electronics to become the world’s most valuable memory chipmaker, according to market data released on June 22, 2026. The change marks the first time since 2000 that Samsung has lost its leading position in the global memory sector, underlining how rapidly the semiconductor landscape has shifted. The surge is driven primarily by intense demand for High-Bandwidth Memory (HBM) chips, which are critical for powering modern artificial intelligence infrastructure, including the large language models and other AI workloads that underpin generative AI services. SK Hynix has emerged as the dominant supplier of these advanced chips, helping to reshape competitive dynamics across the memory industry. South Korea — Investors have rewarded SK Hynix’s HBM leadership, pushing its share price up about 340% over the past year and propelling its market capitalization ahead of Samsung’s common shares. The company’s vertically stacked memory architecture boosts data transfer speeds and energy efficiency compared with traditional designs, reinforcing its appeal for AI data centers. While SK Hynix now holds the top spot by this widely cited metric, Samsung Electronics has disputed the ranking, arguing that preferred shares should be included in its total valuation. Market analysts, however, note that SK Hynix has secured key supply roles with major U.S. technology customers including Nvidia and Alphabet’s Google, cementing its position at the center of the AI-driven memory boom roughly two decades after it neared financial collapse.
