SK Hynix is rapidly approaching a historic $1 trillion market capitalization, only weeks after Samsung Electronics achieved the same milestone. The remarkable rise highlights South Korea’s growing dominance in the global artificial intelligence industry and the increasing demand for advanced semiconductor technology.
Shares of SK Hynix have surged more than 200% in 2026 after an extraordinary 274% rally in 2025. The company’s explosive growth has been fueled by soaring demand for AI memory chips, including high-bandwidth memory (HBM) used in AI servers and data centers. Investors continue to pour money into AI-related semiconductor companies as the global race for artificial intelligence infrastructure intensifies.
If SK Hynix crosses the trillion-dollar valuation mark, South Korea will become the first country outside the United States to host more than one trillion-dollar company. Samsung Electronics officially became the nation’s first trillion-dollar corporation earlier this month, while Taiwan Semiconductor Manufacturing Company (TSMC) remains Asia’s largest company with a market value exceeding $1.83 trillion.
Analysts say investor enthusiasm surrounding AI technology continues to drive markets higher across Asia. According to market experts, fear of missing out on AI-focused investments has intensified buying activity in Japanese and Korean technology stocks.
South Korea’s benchmark KOSPI index has also experienced a historic rally, climbing more than 86% this year after gaining 75% in 2025. Since the beginning of 2025, the KOSPI has become the world’s best-performing major stock market, supported heavily by foreign investment into semiconductor companies.
SK Hynix, once valued below $100 billion less than two years ago, is now approaching the market values of global giants such as Walmart and Berkshire Hathaway. Despite a slight dip in shares recently, the company’s market capitalization remains close to $950 billion, reinforcing its position as one of the world’s most influential AI chipmakers in 2026.
