South Korean chip giant SK Hynix raised a record-breaking $26.5 billion in its debut on the Nasdaq, marking the largest initial public offering by a foreign company in United States history. The South Korean memory chipmaker began trading Friday under the ticker symbol SKHYV before transitioning to SKHY for regular trading on Monday, priced at $149 per share.
The landmark listing surpasses the previous record held by Chinese e-commerce giant Alibaba, which raised $25 billion during its 2014 U.S. debut. SK Hynix’s offering consisted of 177.9 million American depositary receipts, with demand reaching roughly seven times the number of available shares, reflecting robust global appetite for companies positioned at the center of artificial intelligence infrastructure expansion.
SK Hynix’s dramatic ascent to the U.S. market represents one of the most remarkable turnarounds in the semiconductor industry. The company’s stock price on its existing Seoul listing surged more than sevenfold over the past year, lifting its market capitalization to approximately $1 trillion. Just one year ago, most American investors had never heard of the company, yet it has emerged as an indispensable player in the global race to build artificial intelligence computing power.
The company’s strategic position stems from its dominance in high-bandwidth memory, or HBM, the specialized chips that power artificial intelligence accelerators. SK Hynix controls roughly 56 percent of the global HBM market, making it the primary supplier to Nvidia, the world’s most valuable company. In June, Nvidia CEO Jensen Huang visited SK Hynix in Seoul to announce a multiyear partnership covering the supply and co-development of next-generation memory chips for Nvidia’s entire product roadmap, including its Vera Rubin AI supercomputers and personal AI systems.
The memory shortage consuming global supply chains has become one of the defining constraints on artificial intelligence infrastructure expansion. Data centers are projected to consume up to 70 percent of all memory chips produced worldwide in 2026, creating an unprecedented reallocation of semiconductor manufacturing capacity away from consumer devices toward AI infrastructure. This structural shift has driven demand for SK Hynix’s products to extraordinary levels.
SK Hynix’s financial performance reflects the intensity of this demand. The company’s annual revenue nearly tripled from 2023 to 2025, reaching approximately $65 billion. For 2026, analysts polled by a major data provider expect revenue to more than triple again to around $235 billion. The company posted record net income of $26.6 billion in the first quarter of 2026 alone, demonstrating the extraordinary profitability of serving the artificial intelligence buildout.
The company announced plans to deploy the proceeds from its U.S. listing toward aggressive capacity expansion. SK Hynix is constructing new production facilities in South Korea to address surging demand, and it plans to spend approximately $7.8 billion on extreme ultraviolet lithography machines, the specialized equipment necessary for manufacturing advanced chips. The company aims to substantially increase its production capacity over the next decade to satisfy the ongoing growth in artificial intelligence infrastructure.
In the United States, SK Hynix is building its first domestic production facility, a $4 billion advanced packaging plant in West Lafayette, Indiana, scheduled to begin operations in 2028. The facility will specialize in assembling and testing high-bandwidth memory chips, the critical component of artificial intelligence accelerators. SK Hynix expects to receive up to $458 million in direct funding from the U.S. CHIPS and Science Act, the legislation designed to restore domestic semiconductor manufacturing capacity. The company may also receive up to $570 million in loans from the U.S. Commerce Department. The Indiana project is expected to generate approximately 1,000 new jobs in the region and represents the largest single development project in Indiana’s history once completed.
The IPO coincides with extraordinary volatility in semiconductor stocks driven by artificial intelligence investment enthusiasm. In recent months, comments from SK Hynix suggesting it would slow its expansion triggered sharp selloffs in South Korean and global stock indexes, underscoring how central the company has become to investor sentiment regarding artificial intelligence infrastructure sustainability. Some analysts have expressed concerns about excessive froth in memory chip stocks, given the cyclical nature of the semiconductor industry and the potential for overcapacity to emerge.
Despite these concerns, the strong demand for SK Hynix’s U.S. listing indicates that global investors maintain substantial confidence in the durability of artificial intelligence memory demand. Market observers noted that SK Hynix’s U.S. listing allows American investors direct access to what has emerged as one of the hottest trades of the year, closing a gap in the market. The company’s successful debut also signals continued appetite for companies positioned throughout the artificial intelligence supply chain, even as some of the largest technology stocks have experienced recent valuation pressure.
SK Hynix’s transformation from a relatively obscure South Korean chipmaker to a trillion-dollar company commanding the largest U.S. listing by a foreign company reflects the scale and urgency of global artificial intelligence infrastructure investment. The company’s financial success and aggressive expansion plans suggest manufacturers anticipate sustained high demand for memory chips as technology companies continue their massive buildout of artificial intelligence computing capacity. Whether that optimism proves justified will significantly influence not only SK Hynix’s future performance but also the trajectory of artificial intelligence infrastructure expansion worldwide.
