SK Hynix Prepares $14 Billion US IPO Amid Extreme Swings, Powered by Nvidia's Vera Rubin Deal

SK Hynix cements multi-year tech pact with Nvidia for Vera Rubin and Jetson Thor, while prepping a $14B US listing. Stock swings near 99% annualized volatility as foreign investors retreat.

The memory-chip giant SK Hynix is weathering a storm of volatility while deepening its strategic alliance with Nvidia and charting a historic move to Wall Street. A single session this week saw the stock plummet over 7% one day only to explode nearly 16% higher the next, as investors digested a multi-year technology pact covering Nvidia’s next-generation Vera Rubin supercomputers and Jetson Thor robotics platforms.

The massive rebound on Tuesday led the broader KOSPI index, which surged roughly 8% after a comparable rout the previous Monday. Market breadth improved sharply — 774 stocks rose against just 133 falling — but foreign investors remained cautious, pulling a net 2 trillion won out of the market. Domestic institutional buyers stepped in to absorb the selling, indicating the rally was driven more by short-term positioning than a sustained return of international capital.

SK Hynix closed the session at 2,215,000 won, trimming its week-to-date loss to 3.6%. The stock now trades about 8% below its 52-week high and a staggering 47% above its 50-day moving average. Annualized volatility has surged to nearly 99%, underscoring the extreme swings that have characterised the stock since the start of the year.

The renewed partnership with Nvidia goes beyond simple supplier ties. Under the agreement, SK Hynix will integrate its memory chips directly into Nvidia’s processor designs for the Vera Rubin supercomputers and the Jetson Thor line of AI-enabled robots. The South Korean company is also adopting Nvidia’s software libraries to accelerate its own chip development and move toward fully autonomous factories, using digital twins to boost production efficiency. SK Group chairman Chey Tae-won called the collaboration a milestone in joint innovation.

On the funding front, SK Hynix is preparing to raise up to $14 billion through a US listing of American depositary receipts, potentially as early as August. The Securities and Exchange Commission is expected to review the application by the end of June, opening access to a vast pool of American capital that could fuel further expansion of HBM4 memory production.

Year-to-date gains fluctuate with the daily swings. As of the latest close, SK Hynix has returned 227% since January, compared with a 202% gain recorded earlier in the week when the stock was trading closer to the 2 million won level. The shares remain roughly 15% below their all-time high, a gap that could narrow or widen rapidly given the stock’s frenetic pace.

With the Nvidia deal locking in demand for the next generation of AI infrastructure and a Wall Street listing on the horizon, SK Hynix is positioning itself at the intersection of technological leadership and global capital markets. But the persistent selling by foreign investors and the stock’s near-100% annualized volatility mean that any shift in sentiment can trigger another sharp reversal.
