SK Hynix Rebounds 16% as $44 Billion Won Machine Order and Nvidia Pact Converge

SK Hynix shares surge 16% after placing $44B HBM4 equipment order and deepening Nvidia alliance, lifting YTD gains to 227% amid extreme volatility.

South Korean memory giant SK Hynix is back on the front foot after a brutal Monday that saw its stock tumble below the 2 million won threshold amid broader KOSPI panic. Buyers returned with force on Tuesday, pushing shares to 2,216,000 won — a near-16% surge that lifted the year-to-date gain to 227%. The sharp reversal was sparked by two closely related developments: a major equipment order for the next generation of AI memory chips and a deepened strategic alliance with Nvidia.

The company has placed a 44 billion won order with Hanmi Semiconductor for specialized “TC Bonder” machines, a critical piece of kit for manufacturing HBM4 (High Bandwidth Memory 4) chips. Analysts estimate the order covers roughly 15 units, which will be delivered to the Cheongju plant by early September 2026. The move prepares for mass production of the advanced memory destined for Nvidia’s upcoming Vera Rubin AI platform.

This capital expenditure is the hardware counterpart to a sweeping technology partnership signed the day before. SK Hynix and Nvidia have agreed to co-develop custom memory solutions for Nvidia’s next-generation systems, including the Vera Rubin supercomputer and the Jetson Thor robotics platform. Nvidia CEO Jensen Huang underscored the strategic importance, stating that SK Hynix will remain the chipmaker’s largest memory partner. The collaboration extends beyond components: SK Hynix is integrating Nvidia’s AI libraries and the Omniverse digital-twin platform into its own fabrication processes, aiming to create fully autonomous, AI-driven factories. That digital transformation is designed to give the Korean firm a structural cost and speed advantage in the fiercely competitive memory market.

The twin catalysts have not erased all traces of recent turbulence. On a weekly basis, SK Hynix shares were still nursing a 19% loss as of Tuesday’s close, and the stock recently corrected from an all-time high of around 2.4 million won. The 30-day volatility stands at a staggering 99%, while the annualized figure clocks 90% — a stark reminder of the stock’s sharp swings. The new M15X fabrication facility, which the company plans to ramp to 40,000 wafers per month in the second half of 2026, is central to the expansion narrative.

Technically, Tuesday’s rally lifted the relative strength index to 62, leaving room for further upside without entering overbought territory. With only about 8% separating the current price from the record high, the path forward hinges on sustained appetite for AI chips and flawless execution of the HBM4 timeline. The deepening integration with Nvidia — including early access to future specifications — provides a long-term moat, but the extreme volatility suggests the ride will remain anything but smooth.
