What is happening with Stargate?
OpenAI's Stargate project, the company's ambitious infrastructure platform designed to power its path toward artificial general intelligence, is expanding rapidly on multiple fronts. In a series of announcements, the company revealed a 4.5 gigawatt partnership with Oracle, five new datacenter sites across the United States, and the addition of Samsung and SK as partners to extend the initiative into South Korea.
The numbers are staggering. The full buildout now targets 10 gigawatts of compute capacity, backed by approximately $500 billion in investment. To put that in perspective, 10 gigawatts is roughly equivalent to the output of ten large nuclear power plants, all dedicated to running AI workloads.
Who are the key partners?
OpenAI is orchestrating the effort, but the project relies on a coalition of technology and infrastructure giants. Oracle is contributing 4.5 gigawatts of additional datacenter capacity through a new agreement focused on U.S. facilities. SoftBank is involved in the broader $500 billion buildout alongside Oracle and OpenAI.
The newest additions are Samsung and SK, two South Korean conglomerates that bring critical expertise in memory chip manufacturing. Their participation signals that Stargate is not just about building datacenters. It is also about securing the advanced semiconductor supply chain needed to fill those facilities with capable hardware.
