Overview
For the first time in 25 years, SK Hynix has surpassed Samsung Electronics in market capitalization, closing at 2,080.4 trillion won ($1.35 trillion) compared to Samsung's 2,066.7 trillion won. This significant milestone is attributed to a remarkable 300% increase in SK Hynix shares in 2026, driven by strong earnings and a revaluation of memory chips in the context of artificial intelligence (AI).
Controversy Over Market Capitalization
Samsung quickly contested the claim, arguing that a fair comparison should include preferred shares, which would raise its total market capitalization to approximately 2,252 trillion won. Preferred shares, while typically non-voting, are considered legitimate economic claims and are often included in market cap calculations globally.
Historical Context of SK Hynix
To understand SK Hynix's rise, one must consider its tumultuous past. In 2002, the company was on the brink of collapse due to excessive debt and was nearly sold to Micron Technology. After surviving a decade under creditor control, SK Hynix's shares plummeted to as low as 135 won, earning it the nickname "Dongjeon-ju" or penny stock.
Despite facing a significant operating loss of 7.73 trillion won in 2023 due to a pricing downturn, the company rebounded as AI investments surged, leading to a doubling of its annual operating profit in 2025 to a record 47.2 trillion won.
Strategic Position in AI Memory Market
SK Hynix's success is largely due to its early investment in high-bandwidth memory (HBM) technology, which offers superior performance compared to conventional DRAM. By mid-2025, SK Hynix commanded 62% of the global HBM market, while competitors Micron and Samsung held 21% and 17%, respectively. This technology is crucial for AI processors, allowing SK Hynix to avoid the price wars typical of standard memory products.
As demand for AI-specific memory chips is projected to grow by 30% annually through 2030, SK Hynix's pricing power appears sustainable.
Investor Sentiment and Future Prospects
Wall Street analysts remain optimistic about SK Hynix's future. Bernstein has raised its price target for the company significantly, citing the potential for a major margin redistribution in the memory market. Bank of America has named SK Hynix its top global memory pick, predicting a 51% increase in global DRAM revenue, framing the current market as a "supercycle" driven by AI.
Additionally, SK Hynix is preparing for a Nasdaq listing, which could enhance its valuation and attract significant investment from tech-focused ETFs.
Challenges Ahead
Despite its successes, SK Hynix faces challenges, including potential pushback from tech giants due to rising HBM prices and increased competition from Samsung, which has begun shipping its own HBM4 chips.
Nonetheless, the shift in the memory market dynamics indicates that advanced memory chips are now essential for AI infrastructure, positioning SK Hynix as a key player in this evolving landscape.
Conclusion
SK Hynix's transformation from a struggling company to a leader in the AI memory market underscores the changing nature of technology and investment. As the demand for advanced memory continues to grow, SK Hynix's strategic decisions and technological advancements will likely keep it at the forefront of the industry.
