Analysis
SK Hynix, the world's second-largest memory chipmaker and a critical supplier of high-bandwidth memory (HBM) to Nvidia's AI accelerators, filed paperwork for a landmark U.S. listing on July 6, offering 177.9 million American Depositary Shares on the Nasdaq Global Select Market under the ticker SKHY. The offering could raise as much as $29.4 billion, positioning it as one of the largest public share sales in history and a direct byproduct of the AI infrastructure boom.
SK Hynix now controls roughly 57% of the global HBM market -- the memory type underpinning Nvidia's GPU platforms -- and about 32% of the DRAM market, giving the offering a direct line to AI-infrastructure demand rather than general semiconductor cyclicality. Each ADS represents one-tenth of one common share.
The deal, coordinated by BofA Securities, Citigroup, Goldman Sachs and J.P. Morgan, has already attracted heavyweight cornerstone commitments totaling up to $7 billion from Baillie Gifford Overseas, Coatue Management and Situational Awareness Partners -- a signal of how aggressively growth investors are chasing AI-chip supply-chain exposure ahead of pricing.
“Samsung Electronics and SK Hynix together account for more than 40% of South Korea's Kospi index, so a U.S.”
Trading could begin as soon as July 10. The listing follows SpaceX's record $85.7 billion Nasdaq debut in June, reinforcing 2026 as a historic year for mega-cap tech IPOs and giving investors a fresh data point on how public markets are pricing AI infrastructure plays outside of the usual U.S.-domiciled names.
Samsung Electronics and SK Hynix together account for more than 40% of South Korea's Kospi index, so a U.S. listing also diversifies SK Hynix's investor base beyond a market where its fortunes are already tightly coupled to a single benchmark's AI-chip concentration risk.
For infrastructure investors, the filing is a proxy on whether the HBM supply crunch persists: SK Hynix's valuation ask assumes continued Nvidia-driven demand for its highest-margin memory products, a bet that hinges on AI capex staying elevated through the back half of 2026.
What to watch: whether the deal prices within or above the implied range once bookbuilding concludes, how SKHY trades in its first sessions relative to SpaceX's post-IPO performance, and whether Samsung or Micron respond with their own U.S. listing or capital-markets moves.
