In a move reflecting the radical shift in the global technology sector, memory-chip maker SK Hynix has overtaken Samsung Electronics to become South Korea's most valuable company. According to reports, this leadership shift is attributed to the ongoing boom in artificial intelligence chips, where SK Hynix has gained a significant competitive edge. The massive demand for high-bandwidth memory (HBM) chips required for AI applications has driven the company's market capitalization to record levels.
This milestone comes as semiconductor stocks experience strong momentum, with SK Hynix benefiting from its close partnership with Nvidia to supply advanced HBM chips. Compared to peers, Samsung Electronics has faced challenges catching up with next-generation memory standards, leading to divergent market performance, per market data. Notably, the regional manufacturing sector shows mixed signals, with China's industrial production growing 4.5% YoY in June, according to official data (June 16, 2026).
