SK Hynix completed the largest-ever US initial public offering by a foreign company on 10 July 2026, raising $26.5 billion through an American depositary share offering on Nasdaq. The South Korean memory chipmaker offered approximately 18 million shares, with the deal attracting more than seven times oversubscription as of 9 July, according to Bloomberg Markets. The Guardian Business reported the listing capitalised on strong institutional demand tied to AI datacenter infrastructure buildout.

SK Hynix ADRs were indicated to open 17% above the offering price on debut day, according to Bloomberg Markets, reflecting the scale of demand recorded during the bookbuild. The offering also brought the company to a trillion-dollar market capitalisation, as reported by Cnbc TOP.

SK Hynix is a primary supplier of high-bandwidth memory chips to Nvidia, whose graphics processors are central to AI training infrastructure, and to Apple, as noted by Cnbc TOP. The ADR listing gives US investors direct access to the South Korean manufacturer's shares, with the ticker trading on Nasdaq. The KOSPI index, on which SK Hynix's domestic shares (000660.KS) are listed, fell 10% from all-time highs around the same period, according to Bloomberg Markets.

No regulatory statement or official government comment on the listing itself was reported in the cluster sources. The deal's structure as an ADR offering expands SK Hynix's access to US capital markets without a full domestic re-incorporation, a distinction noted across Bloomberg Markets reporting.
