SK Hynix plans to raise roughly $28 billion through an initial public offering on U.S. markets, according to a Form F-1/A filing submitted to the SEC on July 6, 2026. The company will sell 17.8 million American Depositary Shares — each one representing a tenth of an actual share — with pricing expected Thursday, July 9, and trading to begin on Nasdaq the following day.

The offering's scale has shifted considerably since March 2026, when SK Hynix first confidentially filed its U.S. ambitions with early estimates around $14 billion. The roughly $28 billion target now circulating is nearly double that figure. The company's board formalized the U.S. listing plan on June 24, when early projections ran to $29-29.4 billion. The shift downward this week reflects Seoul's closing share price on Friday rather than a change in the deal's structure — routine movement in large cross-border offerings.

SK Hynix is the world's second-largest memory chipmaker and a principal supplier of high-bandwidth memory, or HBM, used in AI accelerators like Nvidia's data-center GPUs. These memory chips store information that AI systems need to access at very high speed, making them essential to the clusters of specialized processors that AI labs and cloud providers are building out at scale. Demand for HBM has reshaped memory-sector valuations through 2025 and into 2026.

A U.S. listing opens direct access to American capital markets and gives U.S.-based index funds, ETFs, and institutional investors a dollar-denominated way to own the stock without navigating the settlement delays and currency conversion friction that comes with trading directly on the Korea Exchange. This is not a new mechanism — Taiwan Semiconductor Manufacturing Company has traded American Depositary Shares in New York for decades — but SK Hynix's choice to structure a primary offering this way, rather than simply cross-list existing shares, indicates a deliberate move to raise new capital from U.S. investors rather than merely broaden liquidity for Korean shareholders.

Set against the memory market's trajectory, the timing draws comparison to Micron and Samsung, both of which have seen valuations re-rated upward on HBM exposure. What distinguishes SK Hynix is the decision to tap U.S. equity markets directly for primary capital. This supplies the company with a currency-matched funding source for the dollar-denominated spending that HBM and DRAM fabrication plants typically demand.

The gap between the March confidential filing's $14 billion estimate and the $28-29 billion range now on the table warrants close attention as bookbuilding concludes this week. The expansion reflects a marked increase in confidence, among underwriters and the company, in sustained AI-driven memory demand over a four-month span. That confidence will face its first market test when ADRs open for trading and investors signal where they believe HBM pricing power will go from here.

For institutional allocators seeking direct dollar-denominated exposure to the AI memory supply chain without booking trades through a Korean broker, this listing removes that friction from July 10 onward. Whether that access remains durable will rest less on the mechanics of the IPO than on whether HBM demand growth holds up against the fabrication capacity that SK Hynix and its competitors are now racing to bring online.
