SK Hynix market value surpasses 1 trillion dollars, with AI memory demand becoming the primary driver of company valuation.
During the May 27th Asian trading session, SK Hynix's stock price surged more than 10% intraday, with its market value historically breaking through the $1 trillion mark, becoming the second Asian semiconductor manufacturer to reach this milestone following Samsung Electronics, and the third storage chip company globally to exceed a $1 trillion valuation.
Previously, South Korea's Composite Stock Price Index (KOSPI) surged nearly 5%, with KOSPI 200 futures rising 5%, triggering the circuit breaker mechanism and suspending program trading for five minutes.
Over the past year, SK Hynix's stock price accumulated gains exceeding 900%, with a full-year 2025 gain of 274%, and further gains exceeding 200% year-to-date in 2026.
As a core supplier of NVIDIA HBM chips, SK Hynix has benefited significantly from explosive demand for high-bandwidth memory in AI servers. HBM chips are considered a bottleneck in AI infrastructure, as memory bandwidth has become the most critical constraint replacing pure computing power in AI compute deployment.
Since 2025, orders from technology giants including NVIDIA, Google, and AMD to SK Hynix have continued to surge, with the company's full-year 2026 HBM production capacity already sold out, with shortages expected to persist through 2027.
Meanwhile, earlier this month, over 50,000 Samsung Electronics employees were originally scheduled for an 18-day strike. The market expected Samsung's production disruptions to further exacerbate global storage chip supply constraints, prompting customers to accelerate order transfers to competitors including SK Hynix, providing an additional short-term catalyst for the stock price.
Although the strike was announced to be suspended on the evening of May 20th, emergency arbitration by South Korea's Ministry of Employment and Labor merely delayed the strike for 30 days. The fundamental disagreement between labor and management over bonus distribution remains unresolved, and supply concerns have not fully dissipated.
Notably, SK Hynix has secretly filed for a U.S. ADR listing this year, which will enable American investors to directly participate in secondary market trading following the listing. This development opens doors for the company to further attract global capital, and is expected to continue driving a re-rating of its valuation.
Although risks from dependence on a few key customers remain, the market is redefining SK Hynix from a cyclical memory manufacturer to a structural core beneficiary of AI infrastructure. Analysts expect storage chip shortages to persist through 2027, providing SK Hynix, Samsung, and Micron with unprecedented pricing power.
