SK Hynix Locks In a $500 Billion-Plus NVIDIA Alliance, but Can the Memory Giant's Stock Price Keep Pace With Its Ambitions?

Reports emerged this week that SK Hynix and NVIDIA have cemented what may be the largest partnership in semiconductor history, a deal ecosystem valued at over $500 billion — and potentially $750 billion when broader U.S. tech supply commitments are included. For shareholders of the world's second-largest memory chipmaker, the announcement transforms SK Hynix from a cyclical component supplier into a cornerstone of the global AI buildout. The question is whether the market has already priced that in. SK Hynix Just Became NVIDIA's Most Important Partner — But Is the $750 Billion Promise Real or Political Theater?

Reports emerged Friday that SK Group and NVIDIA signed letters of intent for a $500 billion-plus partnership spanning AI data centers and next-generation memory chips, announced at a presidential AI summit in San Francisco. A South Korean presidential adviser separately disclosed that SK Hynix will supply $750 billion in memory chips to U.S. companies including NVIDIA, with Samsung committing another $200 billion to Broadcom. For shareholders, this is the clearest signal yet that the AI memory race is now a geopolitical asset — but the details matter enormously.

The Biggest Memory Deal in History Locks In Revenue Visibility — In Theory. The agreement covers a five-year cooperation period for SK Hynix to supply $750 billion worth of memory chips to U.S. firms including NVIDIA.

That figure amounts to approximately 11.3 times SK Hynix's projected 2025 revenue — a staggering commitment that would guarantee years of factory utilization. But the $750 billion total may represent a guideline instead of binding commitments, and NVIDIA's representatives didn't elaborate on which firms would spend such a large amount or precisely what it would be for. Investors should treat the headline number as a ceiling, not a floor.

Dominance in AI Memory Is the Lever That Makes This Work. SK Hynix leads with approximately 50–55% of the high-bandwidth memory market and was first to mass-produce the latest generation, securing the majority of NVIDIA supply contracts.

NVIDIA alone contributed around 15% of SK Hynix's total revenue in Q1 2026 and about 24% for full-year 2025. This partnership deepens that dependency in both directions — NVIDIA gets guaranteed supply of the specialized memory stacked inside every AI chip, and SK Hynix gets pricing power.

The Stock Isn't Reacting Like a $750 Billion Winner. As of July 25, SK Hynix shares in Seoul traded at ₩1,759,000, down from a previous close of ₩1,919,000 — a sharp decline even as the deal was announced. Seoul shares sit 41.1% below their June 25 peak. The disconnect reflects broader memory-sector anxiety about cyclical downturns — periods when chip prices crash due to oversupply — and skepticism that politically orchestrated mega-deals translate into near-term earnings.

Earnings on Wednesday Will Be the Real Test. Wednesday's results will show if revised supply strategies alter financial projections, with investors watching for details on contract lengths, HBM4 production, pricing, and capital spending.

Bank of America defines 2026 as a "supercycle similar to the boom of the 1990s," forecasting global DRAM revenue to surge 51% year-over-year. If SK Hynix confirms that this partnership backstops its factory expansion plans with real purchase orders, the gap between the stock price and the analyst consensus target of ₩3.4 million could narrow fast.
