The expansion brings the companies closer to their goal of investing US$500 billion in domestic data centres and AI infrastructure

OpenAI plans to invest roughly US$400 billion to develop five new US data centre sites in partnership with Oracle and SoftBank Group, marking the biggest push yet to fulfil an earlier pledge to spend a half-trillion dollars on artificial intelligence infrastructure in the country.

The new locations, spread across Texas, New Mexico and Ohio, will eventually have a capacity of 7 gigawatts of power, or as much as some cities, the companies said Tuesday.

The plans were announced by executives from the three tech firms at a press conference in Abilene, Texas, where OpenAI and Oracle have for months been developing the first data centre branded as part of Stargate, the joint AI infrastructure initiative.
