SK Hynix made a splash on July 10, 2026, by raising $26.5 billion through its Nasdaq debut, selling nearly 178 million American depositary receipts at $149 each. This set a new high for foreign company listings in the US. The stock jumped as much as 17% right after trading began, signaling strong investor confidence.
The impact went beyond the stock market. South Korea’s won, which had been weakening against the dollar for months, suddenly found support. After SK Hynix’s offering, the won strengthened from 1,501.4 to about 1,486 per dollar, marking its best two-month performance.
That’s no coincidence. South Korean officials have been pushing exporters like SK Hynix and Samsung Electronics to bring their foreign earnings back home rather than keeping them offshore. This inflow of dollars being converted into won helps stabilize the currency and counteract recent losses.
SK Hynix isn’t just any chipmaker. It’s the second-largest memory chip producer worldwide and a key player in AI technology. The company supplies high-bandwidth memory chips critical for Nvidia’s GPU clusters used to train AI models. Thanks to booming AI demand, SK Hynix’s stock price soared over 229% in the first half of 2026.
Originally targeting about $14 billion, the deal grew to over $29 billion before settling at $26.5 billion. This huge capital influx is a big deal for currency markets. However, some caution is warranted: the won’s recent gains might ease as these repatriated funds flow through the system and market conditions normalize.
Investors watching South Korea’s semiconductor sector should also consider how sustainable this AI-driven surge is. SK Hynix’s rapid run-up depends heavily on continued strong demand from Nvidia and other tech giants. Any shift in AI hardware needs could ripple through the company’s future performance.
