Microsoft is taking over a massive data center project in Abilene, Texas that OpenAI declined to pursue. The 900-megawatt facility will sit next to OpenAI and Oracle's Stargate campus, marking a shift in the relationship between Microsoft and its former exclusive cloud partner as both companies increasingly pursue AI development separately.

Microsoft Steps Into OpenAI's Abandoned Texas Expansion

Microsoft has agreed to lease a data center project in Abilene, Texas that was originally being developed for Oracle and OpenAI, marking a notable shift in the relationships between these AI powerhouses

2

. Data center developer Crusoe revealed plans on Friday to add 900 megawatts of capacity to support Microsoft AI ambitions at the site, which will be located directly adjacent to the 1.2 gigawatt facility Crusoe is building for OpenAI and Oracle as part of the $500 billion Stargate initiative

. The deal came together after negotiations between Oracle and OpenAI fell through over financing issues and OpenAI's frequently changing needs

. Meta Platforms also discussed renting the site before Microsoft ultimately secured the agreement with Crusoe .

Massive AI Computing Campus Takes Shape in Abilene, Texas

The new Crusoe data center campus will feature two AI factory buildings along with an on-site power plant capable of delivering 900-megawatt of behind-the-meter energy to the facilities

1

. Each of the bit barns will support 336 megawatts of critical IT load, providing substantial computing power for Microsoft's AI models and services

1

. According to Crusoe co-founder and CEO Chase Lochmiller, "By integrating 900 megawatts of new on-site power generation, we will continue building the industrial foundation for American AI - at a velocity the industry has never seen"

4

. This expansion will bring the total site capacity to 2.1 gigawatts, transforming what was once vast mesquite shrublands into one of the nation's largest AI computing campus complexes

OpenAI and Oracle Continue Separate Development

While Microsoft moves forward with its new facilities, Crusoe has already completed two buildings for OpenAI and Oracle, with six more buildings due for completion by the end of 2026

4

. Only about 200 megawatts of the existing 1.2 gigawatt project have actually been powered on, though Crusoe expects the remaining gigawatt to come online throughout 2026

1

. Sachin Katti, OpenAI's head of compute infrastructure, explained that while the flagship Stargate site is "one of the largest AI data center campuses in the United States," the company ultimately chose to distribute additional capacity across other locations, including a facility being built with Oracle in Wisconsin

4

. The existing OpenAI and Oracle project includes a 350-megawatt, gas-fired power plant that Oracle has described as a backup power source, with the data centers primarily drawing from the regional electricity grid

Shifting Dynamics Between Former Partners

The arrangement highlights how Microsoft and OpenAI are increasingly pursuing AI development separately, even as they become neighbors on the same tract of land

4

. Microsoft was once OpenAI's exclusive cloud-computing provider and still holds a roughly 27% stake in the ChatGPT maker, but their relationship has evolved significantly

5

. During its most recent quarter, Microsoft inked about $50 billion in commitments to lease server farms under development, marking a reversal from about this time last year when the company paused many data center projects . The world's largest software maker has accelerated data center leasing to meet demand for cloud-computing customers and internal work on artificial intelligence, including generative AI services like Copilot .

Energy Concerns and Timeline for AI Infrastructure

Work on the Microsoft campus is currently in the land-clearing and site preparation phase, with Crusoe not anticipating the facilities will be operational until mid-2027

1

. While Crusoe didn't elaborate on how its on-site power plants generate electricity, the timeline suggests natural gas generators or fuel cells are the most likely candidates

1

. The AI race has complicated tech companies' commitments to reduce greenhouse gas emissions. OpenAI CEO Sam Altman acknowledged during a visit to Abilene, Texas last year, "We're burning gas to run this data center," though he expressed hope that "in the long trajectory of Stargate" the facilities would rely on many other power sources

5

. Technology companies continue pouring billions into data centers to power generative AI services such as ChatGPT and Copilot, which require massive amounts of energy consumption and computing resources
