SK Hynix made Wall Street history on Friday, with the South Korean memory-chip maker opening at about $170 per share — roughly 14 percent above its $149 offering price — as it raised approximately $26.5 billion in the largest-ever US listing by a foreign company. The deal surpassed Alibaba’s 2014 record and hands the AI-memory trade a fresh, very large validation just as investors were questioning whether the semiconductor rally had run out of room.
The numbers behind the debut
The listing valued SK Hynix at roughly $1.27 trillion, placing it among the most valuable companies listed in the US. Demand was extraordinary: the offering was oversubscribed more than seven times, implying orders well above $180 billion. Micron, its closest listed rival, slipped modestly on the day as capital rotated toward the new entrant — a preview of how the memory trade may reshuffle rather than simply expand. As a key supplier of high-bandwidth memory to Nvidia and others, SK Hynix sits at the centre of the AI-infrastructure build-out, and its debut is the second enormous share sale in weeks after SpaceX’s flotation last month.

What to watch from here
The stock traded in when-issued form on Friday under the temporary ticker SKHYV and transitions to regular-way trading today, July 13, under the ticker SKHY. That switch is the immediate technical event, but the strategic question is bigger: whether SK Hynix pulls chip stocks back into an uptrend heading into earnings, or triggers the kind of sell-the-news fade that followed the SpaceX debut. One structural difference matters for how it plays out — SpaceX drew heavy retail interest, whereas SK Hynix is fundamentally an institutional deal. For the AI-memory complex, the size of the order book is the signal: a rally that was supposedly losing momentum just absorbed one of the largest listings in market history.
