SK Hynix IPO Becomes Biggest Foreign US Listing

SK Hynix Rings In the Biggest Foreign IPO in US History

Wall Street had a blockbuster debut to celebrate this week. On July 10, 2026, memory-chip giant SK Hynix listed in the United States, raised $26.5 billion, and closed its first day up about 13%. It is the largest US IPO ever by a foreign company, surpassing Alibaba's 2014 record — and a strong signal of investor appetite for the companies powering the AI boom.

• The debut: ADRs priced at $149 and closed the first day at $168, a gain of about 13%
• The size: $26.5 billion raised across 177.9 million American depositary receipts — the biggest-ever US listing by a foreign firm
• The demand: orders ran roughly seven times the available shares
• The tickers: trading under SKHYV on July 10, moving to SKHY for regular trading the following Monday

Why Was Demand So Strong?

In a word: memory. SK Hynix is a leader in high-bandwidth memory (HBM), the specialized chips that feed data-hungry AI accelerators, and the company controls an estimated 56.4% of the HBM market. As data centers race to build out AI infrastructure, HBM has become one of the most sought-after components in the supply chain — and investors clearly wanted a direct stake in it. That seven-times oversubscription tells the story of a healthy, confident IPO market, a theme we follow across our stock trading coverage.

A US listing also gives American investors easier access to a key player in the AI hardware supply chain that was previously harder to buy. Broadening that access is a genuinely positive development for retail and institutional investors alike who want exposure to the memory side of the AI story.

What This Says About the 2026 Market

A debut this large, this oversubscribed, and this warmly received points to real strength in the new-listings market. It arrives alongside other upbeat milestones we have tracked this year, like Securitize's own NYSE debut, and it reinforces how central AI infrastructure has become to market enthusiasm.

None of this is investment advice — every investor's situation is different. But as a marker of confidence in the IPO market and the AI supply chain, SK Hynix's record-setting debut is a clear bright spot for 2026.
