SK hynix Surges to Open at $170, Topping SpaceX’s Debut

The Number

SK hynix raised $26.5 billion in its Nasdaq American Depositary Receipt offering, a figure the company and its bankers describe as the largest ever for a foreign U.S. listing. The deal priced at $149 per share against an initial target of roughly $28 billion, with the book seven times oversubscribed before allocations closed. This is proceeds raised at pricing, not a market-cap or valuation figure.

What It Means

The $26.5 billion print puts SK hynix in a category shared with only a handful of megadeals. For a Korean memory maker already flagged in filings as a trillion-dollar memory company, the size of the raise reflects both scarcity value in high-bandwidth memory supply and the depth of U.S. institutional demand for AI-adjacent hardware exposure. A book covered seven times over signals that underwriters had room to price higher, and the pricing at $149 leaves that unmet demand visible in the aftermarket. It also gives SK hynix a dollar-denominated equity currency it can deploy against a global capital expenditure cycle that has been running in tens of billions annually across the memory industry.

Market Reaction

Shares opened at $170, a better than 14% gain from the $149 offer price. That opening gap topped the debut of SpaceX (NASDAQ:SPCX), which priced at $135 and opened at $150 for an 11% gap. SpaceX itself has since given back all of that early enthusiasm, trading at $148.64 in noon trading today, down more than 6% over the prior week and more than 5.5% over the prior month. SpaceX’s market capitalization stands at $1.96 trillion intraday today.

Strategic Outlook

The $26.5 billion in fresh proceeds materially reshapes SK hynix’s capital allocation runway. Memory is a fabrication-intensive business where a single leading-edge DRAM or HBM line can absorb several billion dollars, and the raise gives management the option to fund capacity expansion, advance-node conversion, and packaging investment without leaning further on debt markets. The seven-times oversubscription also validates the U.S. listing as a distribution channel for future secondaries or convertible issuance. Reddit sentiment on SKHY tracked bullish, with an average sentiment score of 67 across qualified mentions, though activity levels were low with 4 total mentions. That is a thin retail footprint for a deal of this size, suggesting the demand story is institutionally led.

Bottom Line

Investors are being handed two data points that fit together: a $26.5 billion raise that sets a new bar for foreign U.S. listings, and a 14% opening premium that outpaced the year’s most talked-about debut. The forward catalyst is straightforward. SK hynix now trades on U.S. exchanges with a fully priced deal behind it, and the question is whether HBM demand and AI-driven memory pricing hold up long enough to justify the aftermarket premium that the order book already flagged.
