SK Hynix raises $26.5 billion in biggest foreign IPO in US history

South Korean chipmaker SK Hynix raised $26.5 billion in its US stock market debut on July 10, 2026, marking the largest-ever share sale by a foreign company in the United States. The company’s shares jumped 13% on the first day of trading on Nasdaq, reflecting strong investor appetite for AI-related stocks. SK Hynix is a key supplier of high-bandwidth memory chips used in Nvidia’s AI processors.

The listing comes as demand for AI hardware continues to surge. SK Group’s chairman said the company is open to issuing more US shares in the future. Some US officials have urged SK Hynix to build new fabrication plants in the United States to strengthen domestic chip supply chains.
