SK Hynix Joins the Trillion-Dollar Club, becoming the world's second-largest memory chipmaker to achieve a market capitalization exceeding $1 trillion in April and May 2026. The surge is driven by sustained demand for high-bandwidth memory (HBM) chips used in artificial intelligence servers, a market in which the company is a leading supplier to Nvidia.

SK Hynix's market capitalization surpassed $1 trillion on Wednesday, April 22, 2026, with shares rising over 11% in early afternoon trade. By Friday of the same week, the company's market cap reached approximately $1.10 trillion (1.66 quadrillion won).
- Since the start of 2026, SK Hynix shares have increased by approximately 240% to 250%.
- In the month leading up to the milestone, the share price rose more than 80%.
- Following announcements of a U.S. IPO and equipment acquisition, shares increased by over 5% in Seoul trading.
- Year-to-date stock performance as of late May 2026 was reported at approximately 60%.

Local media reports suggest the company is considering raising between 10 trillion won and 15 trillion won (approximately $6.7 billion to $10 billion). Demand for the offering has reportedly exceeded the number of ADRs available.
- Use of Funds: Proceeds are intended for capital expenditures in South Korea, including expanding production facilities and acquiring EUV lithography scanners.
- CEO Statement: SK Hynix CEO Kwak Noh-Jung stated the company's plan to secure over 100 trillion won in net cash for long-term strategic investments.
Production Expansion and Equipment
SK Hynix is expanding its production capacity to meet demand for memory chips, particularly HBM for AI processors.
- M15X Fab: The new facility in Cheongju, South Korea, was completed ahead of schedule.
- Yongin Semiconductor Cluster: Construction of this $15 billion facility is progressing.
- Indiana Facility: The advanced packaging facility in the U.S. is also progressing.
- ASML Equipment: SK Hynix announced plans to acquire 11.95 trillion won ($7.97 billion) worth of advanced chipmaking equipment from ASML.
Industry and Market Context
SK Hynix's market cap milestone is part of a broader rally in the semiconductor and AI sectors.
- Trillion-Dollar Club: SK Hynix joins 16 other companies worldwide with valuations of at least $1 trillion. It is the second South Korean company (after Samsung Electronics) and the fourth non-U.S. company (alongside Samsung, TSMC, and Saudi Aramco) to achieve this.
- Competitors: Samsung Electronics and Micron Technology also surpassed the $1 trillion market capitalization mark earlier in April and May 2026.
- Samsung Union: Separately, Samsung union members approved a deal awarding bonuses to 78,000 employees, each eligible for up to $370,000 based on operating profit estimates. The union stated that SK Hynix workers received bonuses over three times larger than Samsung's the previous year.
- South Korean Market: Combined, SK Hynix and Samsung Electronics represent over 40% of South Korea's Kospi index. The Kospi nearly doubled since the start of 2026, according to LSEG data. Analysts have noted that this concentration could increase market volatility.
- Global Shortage: The surge in demand for HBM has contributed to a global shortage of DRAM and NAND memory chips, driving up prices.
- Clients: SK Hynix's clients include Nvidia, Google, and Microsoft.
