SK Hynix plans to sell nearly 17.8 million American depositary shares in a U.S. initial public offering, according to a Form F-1/A filing submitted to the SEC on Monday, July 6, 2026 TechCrunch. Each ADR will represent one-tenth of a common share. Based on SK Hynix's closing share price in Seoul on Friday, July 3, 2026, the offering could raise roughly $28 billion, Bloomberg's calculation cited by TechCrunch shows.

Pricing is expected Thursday, July 9, 2026, with ADRs set to begin trading on Nasdaq the following day, Friday, July 10 TechCrunch. The underlying F-1 registration statement, filed under CIK 0002120882, describes the offering as common shares represented by American Depositary Shares, and discloses that SK Hynix's board of directors took formal action related to the U.S. listing on June 24, 2026.

That June 24 date also produced the offering's first public size estimates, and they were larger than what eventually surfaced this week. Bloomberg reported SK Hynix was seeking to raise $29.4 billion Bloomberg, while Reuters put the figure at $29 billion and noted that ADR bookbuilding was scheduled to begin July 6 Reuters. The roughly $28 billion figure now circulating reflects Friday's Seoul closing price rather than a change in deal structure, and modest gaps between early target ranges and market-price-implied valuations at bookbuilding are routine in large cross-border listings.

The scale of this offering has grown substantially since SK Hynix first signaled its U.S. ambitions. The company filed confidentially for a U.S. listing in March 2026, and a source told Reuters at the time that the offering could raise as much as $14 billion Yahoo Finance. The current target is roughly double that early estimate, a gap that tracks the memory market's trajectory over the intervening months rather than any single catalyst identified in the filings.

SK Hynix is the world's second-largest memory chipmaker and a principal supplier of high-bandwidth memory (HBM) used in AI accelerators, including Nvidia's data-center GPU lines. Demand for HBM has been the primary driver of memory-sector valuations through 2025 and into 2026, as hyperscalers and AI labs have continued to expand GPU cluster buildouts that require HBM stacks alongside compute silicon. A U.S. listing gives SK Hynix direct access to American capital markets and a dollar-denominated equity instrument that U.S.-based index funds, ETFs, and institutional investors can hold without the settlement and currency frictions that come with trading directly on the Korea Exchange.

The mechanics here matter to anyone tracking how Asian chipmakers access Western capital. ADRs are a well-established instrument — Taiwan Semiconductor Manufacturing Company has traded ADRs in New York for decades — but a company of SK Hynix's size choosing to structure a fresh primary offering as ADRs, rather than simply cross-listing existing shares, signals an intent to raise genuinely new capital from a U.S. investor base rather than merely broaden liquidity for existing Korean shareholders.

Set against the broader memory cycle, the timing invites obvious comparison to Micron and Samsung, both of which have also seen valuations re-rated upward on HBM exposure. What distinguishes SK Hynix's move is the decision to tap U.S. equity markets directly rather than rely solely on capital raised through its Korean listing or debt issuance, a path that gives the company a currency-matched funding source for the dollar-denominated capital expenditure that HBM and DRAM fab expansion typically require.

In this author's view, the widening gap between the March confidential filing's $14 billion estimate and the roughly $28-29 billion range now on the table is the detail worth watching most closely as bookbuilding concludes this week. It suggests underwriters and the company itself have grown considerably more confident in sustained AI-driven memory demand over a four-month window, a bet that will be tested the moment ADRs open for trading and the market renders its own verdict on where HBM pricing power goes from here.

For institutional allocators who have wanted direct dollar-denominated exposure to the AI memory supply chain without booking trades through a Korean broker, this listing removes that friction starting July 10. Whether that access proves durable will depend less on the mechanics of the IPO than on whether HBM demand growth holds up against the capacity that SK Hynix and its competitors are now racing to build.
