South Korea's memory chip giants are locking in multi-year supply contracts with American tech companies, signaling a structural shift in how the semiconductor industry does business
Samsung Electronics and SK Hynix are preparing to announce significant long-term memory chip supply contracts with US technology companies on July 24, during South Korean President Lee Jae Myung’s visit to San Francisco. A senior presidential official described the expected contract values as “very large and meaningful figures.”
The shift isn’t happening in a vacuum. It’s being driven by demand for advanced memory chips, particularly high-bandwidth memory, or HBM, used in AI training and inference workloads.
SK Hynix has already been moving in this direction. In June 2026, the company signed a multi-year technology partnership with Nvidia focused on developing next-generation AI memory solutions for data centers and supercomputing applications.
In May 2026, SK Hynix reportedly received unprecedented proposals from global technology firms offering to invest directly in new production lines and equipment purchases.
Samsung and SK Hynix together dominate the global memory chip market. Their willingness to commit to long-term supply arrangements reflects a strategy to stabilize the volatile memory chip market and provide revenue visibility that the sector has rarely enjoyed.
The diplomatic packaging of these announcements, timed to coincide with President Lee’s San Francisco visit, adds a geopolitical layer. South Korea has been working to strengthen its technology alliance with the United States, and semiconductor supply agreements serve as both economic and strategic assets.
SK Hynix has been the clear leader in HBM technology, having secured the Nvidia partnership and received those unprecedented investment proposals. Samsung has been playing catch-up in the HBM space, and the scale of its US contracts could signal whether it has closed the gap or is still trailing its domestic rival.
