SK Hynix IPO Was 7 Times Oversubscribed as Even Top Investors Got Fewer Shares
- SK Hynix and its record $26.5 billion US IPO were seven times oversubscribed, with even cornerstone investors receiving fewer shares than they requested
- Strong institutional demand reflects continued confidence in AI infrastructure, as SK Hynix remains the leading supplier of high-bandwidth memory (HBM) chips used in Nvidia-powered AI systems
- The AI investing boom is now spreading beyond the IPO, with new leveraged ETFs and surging trading activity showing growing speculative interest in Korean semiconductor stocks
SK Hynix’s IPO has already broken records, but the biggest takeaway wasn’t the $26.5 billion it raised. Behind the scenes, investors were scrambling for a larger slice of the offering than the company was willing to hand out. Even some of the world’s biggest institutional funds walked away with fewer shares than they had requested. This shows that appetite for AI infrastructure investments remains significantly strong despite recent volatility in semiconductor stocks.

SK Hynix IPO Demand Shows AI Infrastructure Trade Is Far From Over

According to reports, the SK Hynix IPO was about seven times oversubscribed. It attracted orders from more than 500 institutional investors. Cornerstone investors, including Baillie Gifford, Coatue Management, and Situational Awareness Partners, received around $5 billion worth of American depositary receipts (ADRs). This is roughly $2 billion less than the maximum allocations they had sought during bookbuilding.
The company raised $26.5 billion, making it the largest US listing ever by a foreign company. It surpassed Alibaba’s landmark 2014 IPO. The shares were priced at $149. This shows a premium of roughly 3% to the previous closing price of SK Hynix’s Seoul-listed stock.
The strong demand came even as SK Hynix shares in South Korea pulled back this week. This revealed how institutional investors remain focused on the company’s long-term position in the AI supply chain rather than short-term price swings.

Amidst this, SK Hynix has become one of the biggest winners of the AI boom. The company is the world’s largest supplier of high-bandwidth memory (HBM). This is a critical component used alongside Nvidia’s AI GPUs to process massive datasets more efficiently. According to the company’s SEC filing, it currently holds about 56.4% of the global HBM market. It is ahead of rivals Samsung and Micron.
The proceeds from the US listing will reportedly help fund new manufacturing capacity in South Korea as demand for AI memory continues to outpace supply. Industry analysts expect shortages of advanced memory chips to persist for years as hyperscalers expand data centers to support generative AI workloads.

The excitement around SK Hynix isn’t stopping with its record US listing. Bloomberg reported that at least six new leveraged ETFs tied to the chipmaker are expected to launch. This gives traders products that deliver twice the stock’s daily return.
Similar products have already gained massive traction in Hong Kong and South Korea. According to CLSA and Bloomberg data, trading in Samsung, SK Hynix, and their leveraged ETFs now accounts for more than 70% of turnover on the KOSPI. This shows how AI-driven chip stocks have become the center of speculative trading.
