SK Hynix briefly surpassed Samsung Electronics in market capitalization on Monday, marking a historic milestone in South Korea’s corporate landscape. The AI-driven semiconductor boom has propelled the memory chip giant to the top, ending Samsung’s more than two-decade reign as the country’s most valuable listed company.
Shares of SK Hynix surged 5.7% during trading, lifting its market value to approximately 2,082.5 trillion won ($1.35 trillion). In comparison, Samsung Electronics gained just 0.4%, bringing its market capitalization to around 2,081.3 trillion won, excluding preferred shares. Samsung had maintained its position as South Korea’s most valuable company since 2000.
The remarkable rise of SK Hynix reflects the growing importance of artificial intelligence and high-performance computing. Demand for advanced memory chips has soared as major U.S. technology companies continue investing heavily in AI infrastructure and data centers. This trend has tightened chip supply, increased memory prices, and boosted profitability across the semiconductor industry.
SK Hynix has emerged as one of the biggest beneficiaries of the AI revolution. The company’s stock has climbed more than 340% this year, significantly outperforming Samsung Electronics, whose shares have risen about 200% during the same period. Investors have increasingly favored SK Hynix due to its strong position in high-bandwidth memory (HBM) chips, a critical component used in AI processors and servers.
The broader semiconductor sector has also experienced substantial gains. In May, SK Hynix joined industry rivals Samsung Electronics and Micron Technology in achieving a market valuation exceeding $1 trillion for the first time. The milestone underscored the growing investor confidence in memory chip manufacturers as AI adoption accelerates worldwide.
Although the lead was brief, SK Hynix’s rise above Samsung highlights the shifting dynamics within the global semiconductor market. With artificial intelligence continuing to drive demand for advanced memory solutions, SK Hynix is well-positioned to maintain its momentum and strengthen its role as a leading player in the rapidly expanding AI chip industry.
