OpenAI’s ambitious Stargate project, a cornerstone of the AI infrastructure race, has secured preliminary agreements with South Korean semiconductor powerhouses Samsung Electronics and SK Hynix to supply massive volumes of DRAM wafers, potentially devouring up to 40% of global production by 2029.
The deals, formalized as letters of intent in October 2025 following high-stakes meetings involving OpenAI CEO Sam Altman, South Korean President Yoon Suk Yeol, and executives from both firms, underscore the project’s unprecedented scale and its ripple effects on global tech supply chains.
The partnerships go beyond mere supply: Samsung and SK Hynix, which together command about 70% of the global DRAM market and 80% of high-bandwidth memory (HBM), have committed to ramping production to meet OpenAI’s projected demand of 900,000 DRAM wafer starts per month.
This volume encompasses commodity DDR5, low-power LPDDR4/LPDDR5, premium HBM for AI accelerators, and specialty DRAM types. Notably, initial deliveries will consist of undiced wafers—raw silicon before cutting into individual chips—granting Stargate flexibility in customization and processing. But questions linger on who will handle dicing, packaging into DRAM chips, HBM stacks, or modules, with speculation pointing to potential in-house or third-party fabs.
To contextualize the scale, global 300mm fab capacity is forecasted to hit 10 million wafer starts per month (WSPM) in 2025, per TechInsights. DRAM’s share stood at 22% (about 2.07 million WSPM) in 2024, with analysts like those at TrendForce projecting an 8.7% growth to roughly 2.25 million WSPM in 2025—meaning Stargate could claim around 40% of that capacity at peak. Broader market forecasts from Yole Group predict DRAM revenues surging to $129 billion in 2025, up from prior years, driven by AI demand, with total memory market revenues nearing $190 billion, including NAND.
However, this concentration has fueled warnings of shortages: Counterpoint Research notes 50% price hikes in 2025, with further increases into 2026, impacting consumer electronics like PCs, smartphones, and GPUs.
Deloitte’s 2025 Semiconductor Outlook highlights AI and data centers as key drivers for chip sales growth, even as PC and mobile demand lags.
Stargate, a $500 billion collaboration controlled by OpenAI, Oracle, and SoftBank, aims to deploy multiple gigawatt-scale AI data centers globally to train next-generation models. Launched in January 2025 with a request for proposals from partners, the project has accelerated rapidly.
The flagship site in Abilene, Texas, went operational early, providing 1 gigawatt of capacity. By mid-2025, Oracle pledged an additional 4.5 gigawatts, pushing totals over 5 gigawatts. September brought announcements of five new U.S. sites, escalating investments to $400 billion, and capacity toward 7 gigawatts. In October, Michigan joined with a multi-billion-dollar campus developed by Related Digital, set for construction in early 2026. December saw ground broken on a $15 billion, four-building complex in Wisconsin by Vantage Data Centers, offering nearly 1 gigawatt, and Michigan regulators approving 1.4 gigawatts of power from DTE Energy—despite local opposition over energy costs and grid strain.
These facilities demand enormous resources: thousands of servers per site, each packed with Nvidia Blackwell GPUs and ancillary gear like cooling systems and power delivery—potentially necessitating dedicated power plants, as Altman has toured Asia-Pacific to secure. The Samsung ecosystem’s involvement deepens the alliance. Samsung SDS will co-design and operate Stargate sites in Korea, provide consulting for integrating OpenAI models into enterprise systems, and act as a reseller for services like ChatGPT Enterprise in South Korea.
Samsung C&T and Samsung Heavy Industries are pioneering floating data centers—offshore platforms leveraging maritime tech for superior cooling efficiency and lower emissions, though engineering hurdles remain. Plans include two Korean “Stargate-style” facilities starting at 20 megawatts, positioning South Korea as an AI hub amid high local adoption of OpenAI tools.
Altman lauded Korea’s “incredible tech talent, world-class infrastructure, strong government support, and thriving AI ecosystem” during his visit.
