OpenAI Partners with Samsung, SK Hynix for Stargate Project Chip Supply
In Focus
- Samsung Electronics and SK Hynix are to supply chips for OpenAI’s Stargate Project
- Chip demand for Stargate Project expected to hit 900,000 wafers per month
- Samsung affiliates to support data center design, construction, and operations
- South Korea considers partnership a growth opportunity its chip industry
Chipmakers Samsung Electronics and SK Hynix are set to supply memory chips for OpenAI’s Stargate Project. According to Reuters, the two companies signed letters of intent relating to the data center chip supply on October 1, 2025.
OpenAI’s High Demand for Wafers
News about memory chip supply emerged shortly after OpenAI CEO Sam Altman held a meeting with South Korean President Lee Jae Myung along with the chairmen of SK Hynix and Samsung Electronics in Seoul.
South Korea’s presidential office says OpenAI’s chip demand is expected to reach 900,000 wafers per month. OpenAI is expected to source most of its high-performance memory chips from Samsung and SK Hynix. However, timelines for the chip supply have not been decided yet.
President Donald Trump announced the $500 billion data center investment in January 2025 to enable the U.S. to stay ahead of rival countries like China in the global AI race. Expanding chip availability remains central to the success of OpenAI’s Stargate Project.
In September 2025, Oracle and SoftBank joined OpenAI in building five new data centers, with Oracle announcing $300 billion in Stargate project funding. The Stargate project is expected to create in excess of 100,000 jobs in the U.S.

Samsung, SK Hynix Global Market Share
Collectively, Samsung and SK Hynix control about 70% of the global Dynamic Random Access Memory (DRAM) chip market and about 80% of the HBM market. HBM is a form of DRAM standard that was first manufactured in 2013. It involves stacking chips vertically to reduce energy consumption and save space.
The technology helps in processing huge volumes of data generated by highly complex AI applications. DRAM is mostly used in servers, workstations, and personal computers to store program code and data.
OpenAI’s Chip Supply Partnership at a Glance
- OpenAI CEO met President Myung and the chairmen of SK Hynix, Samsung in Seoul
- OpenAI expected to source most high bandwidth chips from Samsung and SK Hynix
- Timelines for chip supply yet to be agreed
- Samsung and SK Hynix control about 70% of global DRAM chip market
- The two companies also control about 80% of the HBM market
SK Hynix’s Next Generation HBM Chip
SK Hynix is a major HBM supplier for AI chip maker NVIDIA. Last month, the chip maker announced HBM4 production. SK Hynix said it had finalized the internal quality assurance and certification process for its next-generation high-bandwidth memory chips, HBM4 2-layer chip and shipped samples to customers.
South Korea views the partnership with OpenAI as an early advantage in the largest AI infrastructure project in the world. It also presents a unique growth opportunity for the country’s local chip industry.
OpenAI established an office in Seoul in September 2025 as demand for ChatGPT in the country surged. According to the AI startup, South Korea has the second highest number of paying ChatGPT users after the U.S.
