TLDR
- SK Hynix shares climbed 2.6% to 21 million won Thursday, erasing an early 3.5% decline during trading
- Chairman Chey Tae-won revealed the company will triple its wafer production capacity by 2034 to address surging AI chip requirements
- A U.S. market debut is planned for as early as August, with the potential to generate up to $14 billion in funding
- The chipmaker dominates 57% of worldwide high-bandwidth memory revenue and serves as Nvidia’s primary memory supplier
- Shares have surged 240% year-to-date and achieved a historic $1 trillion valuation milestone in May
SK Hynix shares experienced significant volatility Thursday, plummeting as much as 3.5% during morning trading before staging a complete reversal to finish 2.6% higher at 21 million won. The dramatic recovery followed comments from SK Group Chairman Chey Tae-won to Nikkei Asia revealing the company’s intention to triple wafer production capacity by 2034.

The massive capacity buildout directly responds to accelerating demand for high-bandwidth memory chips powering AI server infrastructure. SK Hynix currently has four semiconductor manufacturing facilities under construction in South Korea’s Yongin district, with the initial plant scheduled to begin operations in early 2027.
According to Chey, the company accelerated its project schedule by an entire decade. The initial roadmap had extended through 2045.
SK Hynix’s recovery helped limit broader KOSPI index losses, although the benchmark still finished in negative territory. Competitor Samsung Electronics declined more than 1% during the session.
U.S. Listing Could Arrive as Soon as August
Along with the capacity announcement, SK Hynix continues advancing toward a U.S. stock exchange listing. Following a confidential SEC filing in March, regulatory approval could arrive during the week beginning June 22, Reuters reported.
The listing structure will utilize American Depositary Receipts. “SK Hynix plans to issue ADRs within 2026, but the details, including the size and timing, have not yet been decided,” the company stated.
The public offering could generate as much as $14 billion, based on a source quoted by Reuters when the confidential filing was submitted.
A U.S. exchange listing would provide SK Hynix access to a broader pool of investors and enable the company to leverage robust interest in AI-focused investments. Should the August timeline materialize, it would enter a crowded period alongside anticipated offerings from OpenAI, Anthropic, and SpaceX.
Nvidia Partnership and Market Position
SK Hynix captures 57% of worldwide high-bandwidth memory revenue based on fourth quarter data from last year. Samsung and Micron split the remaining market share.
The company serves as Nvidia’s primary memory supplier. Nvidia CEO Jensen Huang has confirmed the company allocates billions annually to SK Hynix. The two firms announced a comprehensive multi-year technology collaboration last week focused on developing advanced memory solutions for AI data centers, including Nvidia’s Vera Rubin AI supercomputers and Vera CPUs.
SK Hynix shares have soared 240% during the current year. Its market capitalization exceeded $1 trillion in late May for the first time, establishing it as just the third Asian corporation to achieve that benchmark after TSMC and Samsung.
The stock retreated approximately 11% last week as concerns surrounding the AI investment theme reemerged and anxiety over climbing global interest rates pressured technology equities.
Thursday’s disclosure regarding capacity expansion helped restore investor confidence in the stock.
