SK Hynix priced its Nasdaq American Depositary Share offering at roughly $158 per ADS on July 9, targeting a raise of approximately $28-29 billion in what ranks as the largest-ever US initial share sale by a foreign company. Interim trading under ticker SKHY begins July 10, with full regular trading to follow.
The pricing caps a bookbuilding process that started July 6 with the offering of roughly 177.9 million ADS, each representing a tenth of an ordinary share. Demand ultimately proved stronger than the mid-week jitters suggested: SK Hynix's Seoul-listed shares slid 6.7% on July 7 amid investor concern over dilution from the new ADS issuance, yet the US offering was reportedly oversubscribed by roughly 7 times by the time books closed, according to Korea JoongAng Daily -- a gap between local-market caution and international-investor appetite that's become a recurring pattern in 2026's biggest cross-border listings.
Three cornerstone investors -- Baillie Gifford, Coatue Management and Situational Awareness Partners -- had already committed to roughly $7 billion of the deal before the broader book closed, an unusually large anchor position that gave underwriters BofA, Citigroup, Goldman Sachs and JPMorgan room to price confidently despite the pre-pricing volatility in Seoul.

SK Hynix's raise is the clearest test yet of whether the AI-hardware IPO enthusiasm that drove SpaceX to a $75 billion raise and a $1.77 trillion valuation last month extends beyond US-based names to foreign memory-chip manufacturers. SK Hynix competes directly with Samsung and Micron in high-bandwidth memory, the chip category most directly tied to AI accelerator demand from Nvidia and its rivals -- making this listing as much a referendum on HBM demand durability as on SK Hynix specifically.
A 7x oversubscribed book on a $28-29 billion raise is a strong result by any historical IPO standard, and it suggests that investor appetite for AI-infrastructure exposure remains deep even after SpaceX absorbed an outsized share of available capital just weeks earlier. That's a meaningful data point for the rest of 2026's IPO pipeline: the market hasn't shown signs of AI-infrastructure fatigue yet.
The bear case is the same one that applies to every AI-hardware valuation right now: SK Hynix's pricing assumes HBM demand keeps compounding at its current pace, and any signal of AI capex deceleration from hyperscalers -- Microsoft, Google, Amazon, Meta -- would flow through directly to memory-chip demand and, by extension, to SK Hynix's post-IPO trading range. What to watch next: how SKHY trades in its first days on Nasdaq relative to its $158 pricing, and whether Samsung or Micron follow with their own US listing ambitions if SK Hynix's debut holds.
