SK Hynix raises $26.5B in US share sale, marking second-largest stock listing globally

SK Hynix just pulled off something that most companies only dream about. The South Korean memory chipmaker priced its American Depositary Receipts at $149 each on July 9, raising approximately $26.5 billion in what ranks as the second-largest stock listing globally, trailing only SpaceX.

The offering was oversubscribed by more than seven times. In plain English: for every share available, seven investors were lined up wanting to buy it.

The numbers behind the mega-listing

The deal comprised roughly 177.9 million ADRs, with each receipt representing one-tenth of a common share. Trading is expected to begin on Nasdaq under the ticker SKHY, giving US investors direct access to one of the world’s most critical AI infrastructure companies.

SK Hynix originally aimed to raise up to $29B when the listing was first announced in June 2026. Market volatility forced an adjustment down to the $26.5B figure.

The adjusted figure still makes this the largest inaugural US share sale by a foreign company on record.

The proceeds are earmarked for expanding manufacturing capacity, specifically for high-bandwidth memory chips. HBM, as the industry calls it, is the specialized memory that makes modern AI training and inference possible. Every major AI lab in the world needs it, and SK Hynix is one of a tiny handful of companies that can actually make it at scale.

Why a chipmaker matters to crypto

Without advanced memory chips, the GPUs that power both AI training and crypto mining become significantly less effective. The same HBM chips that SK Hynix is scaling production on are critical components in Nvidia’s data center hardware, which in turn underpins a growing number of decentralized compute projects in the crypto space.

When a company raises $26.5B specifically to build more HBM manufacturing capacity, it’s essentially a massive bet that AI infrastructure demand will continue compounding. That has direct implications for AI-related tokens and decentralized compute protocols that derive their value from the assumption that AI workloads will keep growing.

What this means for investors

SK Hynix’s dominance in HBM production creates something close to a structural monopoly in a market that’s growing faster than almost any other segment of the semiconductor industry. The company has been a primary supplier to Nvidia, and the expansion funded by this listing will only deepen that relationship.

The risk, naturally, is cyclicality. Memory chip markets have historically been brutally cyclical, with periods of oversupply crushing margins. SK Hynix itself has lived through several of these downturns. The bet here is that AI demand fundamentally changes the cycle, creating sustained demand that smooths out the traditional boom-bust pattern.

SK Hynix trading under SKHY on Nasdaq will also create a new public market barometer for AI hardware demand. Crypto traders who already watch Nvidia as a proxy for AI sentiment now have another data point to track, one that’s even more narrowly focused on the memory bottleneck that defines how fast AI can actually scale.
