Microsoft is taking over part of a massive AI data centre expansion in Abilene after OpenAI decided not to pursue further growth at the site, creating an unusual scenario where the two tech giants will operate side by side at one of the largest AI computing hubs in the United States.
Data center developer Crusoe announced it will build two new “AI factory” facilities and a dedicated power plant for Microsoft adjacent to an existing campus developed for OpenAI and Oracle. The expansion will increase the total number of buildings at the site to 10, delivering a combined capacity of around 2.1 gigawatts—enough to power millions of homes.
OpenAI recently confirmed it had dropped plans to further expand its Abilene operations, with its head of infrastructure Sachin Katti stating that the company is redirecting additional capacity to other U.S. locations. Despite scaling back here, OpenAI continues to build multiple sites nationwide, including a project with Oracle in Wisconsin.
The Abilene campus is part of the broader Stargate initiative, a flagship AI infrastructure program publicly highlighted by U.S. President Donald Trump as a major investment in America’s technological future. Originally conceived as a cryptocurrency mining facility, the site was rapidly redesigned after the rise of AI tools like ChatGPT triggered unprecedented demand for computing power.
Crusoe CEO Chase Lochmiller said the new Microsoft-linked power plant will generate 900 megawatts, significantly more than the existing 350-megawatt backup facility supporting OpenAI and Oracle operations. Most electricity will still come from the regional grid, which includes renewable sources like wind energy.
The advancements underscore the growing competition—and cooperation—among leading AI entities. Although Microsoft continues to be a significant investor in OpenAI, both organizations are progressively establishing their own infrastructure to satisfy the escalating worldwide demand for artificial intelligence.
