On July 10, 2026, SK Hynix walked onto Nasdaq and broke every record in the room. The South Korean memory chipmaker raised $26.5 billion by selling 177.9 million American depositary receipts at $149 each, making it the largest share sale by a foreign company in US history.
The shares surged as much as 17% on their first day of trading.
But the story here is not just about a chip company going public. It is about what happens next: SK Hynix is expected to convert a portion of those dollars back into South Korean won, and that currency pipeline is already moving markets.
The won gets a tailwind it desperately needed
The South Korean won had been under pressure for months, grinding weaker against the dollar. Then SK Hynix priced its ADRs, and something shifted.
The won strengthened from around 1,501.4 per dollar on July 10 to approximately 1,486 per dollar shortly after, hitting its strongest level in two months.
South Korean authorities have been encouraging this playbook explicitly. Government officials have been urging major exporters, including SK Hynix and Samsung Electronics, to repatriate their foreign currency earnings rather than leaving them parked overseas.
Why a chip company just became South Korea’s most important currency story
SK Hynix is the world’s second-largest memory chipmaker, and its current market position is deeply tied to AI infrastructure. The company is a critical supplier to Nvidia, providing the high-bandwidth memory chips that power GPU clusters AI model training demands.
SK Hynix’s stock price rose over 229% in the first half of 2026 alone, driven by surging demand for AI-related memory products.
The original estimated deal size was around $14 billion. By the time pricing closed, the offering had grown to exceed $29 billion before settling at $26.5 billion.
What this means for investors watching Korea and semiconductors
The risk side of this equation deserves attention. A $26.5 billion capital raise landing in currency markets is a large, sudden input. As the initial repatriation flows settle and market sentiment normalizes, the won could give back some of its gains.
There is also the question of AI demand durability. SK Hynix’s 229% run in 2026 is predicated on Nvidia and its peers continuing to consume high-bandwidth memory at current rates.
