Hynix Soars 13% on Nasdaq Debut: HBM Architecture Makes It Irreplaceable in AI Chips

Hynix Soars 13% on Nasdaq Debut highlights SK hynix’s strong U.S. market entry, driven by its HBM architecture tied to AI chip manufacturing. The South Korean memory supplier closed its first day on Nasdaq on Friday at $168.01, up 13% from its $149 IPO price, raising $26.5 billion. Regular-way trading under the permanent ticker SKHY begins Monday, July 13, with options expected to list Tuesday, July 14. The article argues the premium reflects more than share of HBM revenue: once a GPU is built, the company’s high-bandwidth memory is physically fused at manufacture and cannot be swapped in deployed systems. SK hynix sold 177.9 million American Depositary Receipts at $149 each, with institutional demand reported at about seven times available shares. The company’s market capitalization is cited at roughly $1.27 trillion, placing it 11th among U.S.-listed firms.
