Nvidia has locked in its memory chip supply from South Korean manufacturer SK Hynix through a major artificial intelligence deal, the companies announced. The agreement reflects the accelerating global competition for semiconductor resources as AI technology reshapes technology markets worldwide.
The deal underscores the critical importance of memory chips in AI infrastructure. These specialized components are essential for training and operating large language models, and securing stable supplies has become a top priority for tech companies racing to expand their AI capabilities. Access to advanced memory chips now serves as a competitive advantage in the rapidly growing AI sector.
South Korea has positioned itself as a crucial player in global semiconductor manufacturing. The country's two largest chipmakers, Samsung Electronics and SK Hynix, have both joined the trillion-dollar company club alongside Taiwan's TSMC, driven primarily by explosive demand for AI chips. SK Hynix's stock price surged 1,000 percent over the past year, while Samsung climbed 500 percent.
This semiconductor boom has transformed South Korea's broader economy. The Kospi index, South Korea's main stock market, has surged 220 percent in the past year and recently reached an all-time high, vaulting the country past India to become the world's sixth largest share market. The index now exceeds the equity markets of the UK, Germany, and France.
However, analysts note concentration risks in South Korea's market expansion. Research indicates that Samsung and SK Hynix have contributed up to 70 percent of the Kospi's growth in 2026, leaving the index heavily exposed to fluctuations in global AI spending and potential supply chain disruptions. The Kospi's volatility index recently reached an exceptionally high level of 75, compared to its historical average of 20, suggesting investor nervousness despite the market rally.
The memory chip market serves different needs than Nvidia's advanced processors. Three companies dominate memory production: Samsung, SK Hynix, and American chipmaker Micron, which recently joined the trillion-dollar valuation club. Their success reflects AI's enormous appetite for these components.
Demand appears underpinned by major technology companies, often called "AI hyperscalers," including Meta, Amazon, Alphabet, and Microsoft. These firms have committed substantial capital to AI infrastructure development, potentially supporting continued growth in the semiconductor sector.
Japan has also experienced gains from the AI boom, with Tokyo's Nikkei 225 index reaching all-time highs. Semiconductor and AI-related stocks have driven much of the growth, with SoftBank Group recently toppling Toyota as Japan's most valuable listed company.
The semiconductor industry historically experienced boom-and-bust cycles, but analysts suggest AI demand may have fundamentally changed that pattern by creating sustained, large-scale chip consumption.
