SK Hynix Valuation Hits USD 1.35 Trillion, Overtakes Samsung To Become World’s Most Valuable Memory Chipmaker
SK Hynix has overtaken Samsung Electronics to become South Korea's most valuable listed company, driven by its dominance in high-bandwidth memory chips for AI systems. Following a near-collapse in 2002, the firm's strategic focus on HBM has propelled its market value to USD 1.35 trillion, positioning it as a core beneficiary of the global AI boom.
SK Hynix has officially overtaken Samsung Electronics to become South Korea’s most valuable listed company, marking a significant reversal of fortune for a firm that was once on the brink of collapse. The shift in leadership underscores the dramatic impact of the global artificial intelligence boom, which has propelled SK Hynix to a market capitalisation of 2,080.4 trillion won (USD 1.35 trillion).
Dominance in the AI Memory Market
The company's rapid ascent is attributed to its dominant position as the leading supplier of high-bandwidth memory (HBM) chips, which are essential components for AI systems developed by companies such as Nvidia and Alphabet's Google. Unlike traditional memory chips, which are treated as interchangeable commodities, HBM chips are tightly integrated with AI processors, providing suppliers like SK Hynix with significant pricing power and higher barriers to entry. By 2025, SK Hynix had secured 61% of the global HBM market, vastly outperforming both Samsung at 17% and Micron at 21%. Dow Layoffs 2026: Why the Chemical Giant Is Cutting 4,500 Jobs Globally.
A Historic Corporate Turnaround
This milestone represents the culmination of one of the most successful turnarounds in South Korean corporate history. In 2002, the company, then known as Hynix Semiconductor, was crippled by debt and nearly sold to Micron. After spending nearly a decade under creditor control, the firm has leveraged strategic investments in HBM to transform itself from a producer of commodity memory into an indispensable player in the semiconductor industry.

Competitive Landscape and Future Outlook
While Samsung remains a diverse manufacturing giant producing logic chips, smartphones, and televisions, SK Hynix’s singular focus on memory has allowed it to capitalise more effectively on the AI-driven shift in semiconductor economics. Analysts suggest that Samsung’s position as the world's largest DRAM producer may also face challenges as SK Hynix aggressively expands its production capacity. Bank of America estimates that SK Hynix will narrow its DRAM output gap with Samsung to less than 10% by 2028, a feat previously considered impossible due to Samsung’s larger manufacturing scale.
