The South Korean memory chip giant has announced plans to raise 45.45 trillion won ($29.4 billion) through a US listing, a move that could rank among the five largest share sales in history. The fundraising underscores just how aggressively companies across the AI ecosystem are investing to keep pace with soaring demand for computing power.
SK Hynix Bets Big on the AI Boom
For years, AI has been driven by advances in software and computing chips. But behind every AI model lies another critical component: memory chips.
SK Hynix has emerged as the clear leader in one of the most important areas of AI infrastructure, known as high-bandwidth memory (HBM). These specialized chips are essential for training and running advanced AI models because they enable processors to access vast amounts of data at extremely high speeds.
As AI adoption accelerates, demand for these chips has exploded.
The company now plans to use the proceeds from its US listing to:
- Expand manufacturing capacity
- Purchase additional extreme ultraviolet (EUV) lithography machines
- Strengthen its position in the fast-growing AI memory market
Trading of the US-listed shares is expected to begin on July 10.
A Historic Fundraising Event
At nearly $30 billion, the offering would place SK Hynix alongside some of the largest public offerings ever.
The deal highlights a broader trend unfolding across the technology industry:
- Companies are raising unprecedented amounts of capital to fund AI infrastructure.
- Massive investments are being made in data centers, semiconductor manufacturing, and AI computing networks.
- Investors continue to pour money into businesses viewed as essential to the AI ecosystem.
Recent examples include large capital raises by leading technology companies and expectations that major AI firms could seek additional funding in the coming months.
The sheer size of SK Hynix’s offering will also test investor appetite. Markets will be watching closely to see whether investors are willing to absorb another mega-sized deal after a strong rally in AI-related stocks.
The Memory Chip Leader
SK Hynix has quietly become one of the most important companies in the global AI supply chain.
According to Counterpoint Research, the company controlled roughly 57% of the global HBM market by revenue in the fourth quarter of 2025.
Industry analysts believe this leadership stems from SK Hynix moving early in the race to develop advanced AI memory chips.
Today, the company supplies memory used alongside the world’s most powerful AI processors, placing it at the center of the ongoing AI infrastructure buildout.
Several factors have strengthened SK Hynix’s position:
- Early investment in HBM technology
- Strong relationships with leading AI chip companies
- Persistent shortages in advanced memory chips
- Rapid growth in AI data center spending
Many analysts expect supply constraints in advanced memory to continue for years, particularly as AI models become larger and more computationally intensive.
Why List in the US?
Beyond raising capital, a US listing offers strategic advantages.
US markets host many of the world’s largest institutional investors and have become the primary destination for global AI investment.
A successful American listing could:
- Broaden SK Hynix’s investor base
- Increase trading liquidity
- Improve global visibility
- Potentially narrow the valuation gap with US competitors such as Micron
Investors often point to Taiwan Semiconductor Manufacturing Company’s US-listed shares as a successful example. TSMC’s American depositary receipts have attracted significant global investor interest and frequently trade at a premium relative to shares listed in Taiwan.
SK Hynix appears to be aiming for a similar outcome.
Valuation Concerns Remain
Despite the enthusiasm surrounding AI, investors are beginning to ask a familiar question:
Can the semiconductor boom continue indefinitely?
The chip industry has historically been cyclical, with periods of rapid expansion often followed by oversupply and weaker pricing.
Recent reports suggesting SK Hynix may slow parts of its AI memory expansion have already sparked concerns that the market could eventually cool.
At the same time, SK Hynix shares have surged roughly 300% this year, pushing the company’s market value above $1 trillion.
Such a remarkable rally raises expectations and leaves little room for disappointment.
Still, the company’s latest financial performance remains exceptionally strong:
- First-quarter operating profit reached a record 37.61 trillion won
- Revenue nearly tripled to 52.58 trillion won
These results suggest AI demand remains robust for now.
The Bigger Picture
SK Hynix’s planned US listing is more than just another fundraising event.
It is another sign that the global AI race is entering a new phase, one defined by massive capital spending, intense competition, and increasingly strategic importance for companies supplying the infrastructure behind artificial intelligence.
Whether the current AI investment cycle continues for years or eventually slows, one thing is clear:
Companies building the foundations of AI are attracting record amounts of capital, and SK Hynix is positioning itself to remain at the center of that story.
