SK Hynix's planned American stock offering has attracted demand for more than seven times the shares available, according to a source familiar with the matter. The South Korean memory chip maker is pursuing what could become one of the largest US initial public offerings in recent years.

The oversubscription reflects strong investor appetite for exposure to the memory chip sector, particularly as semiconductor shortages continue to affect multiple industries. SK Hynix manufactures memory chips used in smartphones, computers, and data centers, positioning the company at the center of ongoing supply constraints in the technology sector.

The offering is expected to value the company at approximately $28 billion, making it one of the most significant listings on US exchanges this year. By listing in the United States, SK Hynix aims to provide American investors with direct access to the memory chip market, which has historically been dominated by Asian manufacturers trading primarily on regional exchanges.

Memory chip makers have seen increased investor interest as artificial intelligence applications drive demand for advanced computing hardware. The sector has experienced periods of both shortage and oversupply in recent years, with prices fluctuating based on manufacturing capacity and global demand patterns. SK Hynix competes with companies including Samsung and Micron Technology in the global memory market.

The listing represents a shift in how international technology companies access US capital markets. While many foreign firms have pursued American depositary receipts or other indirect listing methods, SK Hynix is opting for a direct offering that would give US investors the same share class as other markets. The final pricing and allocation of shares will determine the exact size of the offering and which investors receive allocations in the oversubscribed deal.
