OpenAI and Oracle announce the development of an additional 4.5 GW of Stargate data centres, bringing capacity under development to more than 5 GW, with parts of the Abilene site already running.

### Background On 22 July 2025, OpenAI and Oracle announce they will develop an **additional 4.5 GW of Stargate data centre capacity** in the United States. According to OpenAI, this brings Stargate capacity under development to more than 5 GW and will create more than 100,000 jobs in construction and operations. OpenAI also says construction of the first site, Stargate I in Abilene, Texas, is under way and parts of the facility are already running. Oracle began delivering NVIDIA GB200 racks there the previous month. ### Key facts - Addition: 4.5 GW of Stargate capacity in the United States, developed with Oracle. - Total: more than 5 GW of Stargate capacity under development, according to OpenAI. - Overall goal: 10 GW of new compute capacity through Stargate, according to OpenAI and SoftBank. - Abilene, Texas: parts of the site are running; first GB200 racks delivered by Oracle in June. - Context: the announcement comes a day after a Wall Street Journal report that the project was struggling to get started. ### Why it matters The announcement turns January's ambition into capacity under construction, and makes Oracle a central infrastructure supplier for OpenAI. For Oracle Cloud customers, it shows that much of the capacity will be consumed by a single AI customer, with a concentration risk. The contract's financial terms were not detailed in OpenAI's communication. ### Takeaway Stargate moves from announcement to construction, with more than 5 GW under development and Oracle as infrastructure partner.
