SK Hynix’s Nvidia Pact Goes Deeper Than HBM4: Digital Twins, a $14 Billion Listing, and a Monopoly in the Making
Published on 06/09/2026 at 05:24 | Redaktion boerse-global.de
The relationship between SK Hynix and Nvidia is no longer just about supplying memory chips. A newly cemented technology partnership ties the South Korean manufacturer into the US giant’s entire hardware roadmap, covering supercomputers, robotics, and the factories that make them.
At the core of the deal are custom-designed memory solutions for Nvidia’s upcoming Vera Rubin architecture and Jetson Thor robotics platforms. Nvidia chief Jensen Huang underlined the strategic depth, calling SK Hynix its largest memory partner. This integration goes beyond conventional supply agreements — the two companies will co-develop next-generation HBM4 chips, and SK Hynix is weaving Nvidia’s AI libraries and Omniverse digital twin platform directly into its own production lines. The goal: fully autonomous fabs that accelerate chip design and manufacturing.
The financial logic behind the collaboration is stark. UBS projects SK Hynix will command roughly 70% of the HBM4 market for Nvidia’s Rubin platform next year. That dominance is already visible in the numbers. First-quarter revenue surged 198% year-on-year to 52.6 trillion won, while operating profit multiplied and the operating margin hit 72%. The company expects to ship initial HBM4E samples in the second half of this year, with mass production slated for 2027.
Should investors sell immediately? Or is it worth buying SK Hynix?
To fund this expansion, SK Hynix is preparing a US listing in the second half of 2025, aiming to raise up to $14 billion. Many American pension funds are currently barred from buying South Korean-listed shares, so a direct listing on a US exchange would unlock a fresh pool of capital. The proceeds will flow into a $67 billion investment programme running through 2028, earmarked entirely for new fabrication facilities.
The stock market reaction has been more complicated. Shares closed Monday at 1,911,000 won in Seoul, down roughly 13% over the past week — though some calculations show a 19% decline. The pullback follows a blistering run: year-to-date, the stock has gained around 203% (or 182% on certain measures), and it hit an all-time high of about 2.4 million won earlier this month. The annualised volatility stands at 90%, underscoring that sharp corrections are part of the ride.
Competition is forming on the horizon. Chinese rival CXMT is pushing into the high-bandwidth memory space but lacks access to advanced EUV lithography machines, a bottleneck SK Hynix does not face. With its early access to Nvidia’s specifications and a long-term supply deal in hand, the South Korean chipmaker has locked in what amounts to the industry’s most valuable revenue stream — at least until the next generation arrives.
