The United States and United Arab Emirates will partner to build a massive data center complex in Abu Dhabi to advance artificial intelligence capabilities with 5-gigawatts of capacity — enough to power a major city.

OpenAI is poised to help develop a staggering 5-gigawatt data center campus in Abu Dhabi, positioning the company as a primary anchor tenant in what could become one of the world’s largest AI infrastructure projects, according to a new Bloomberg report.

The announcement came during a Trump visit to Abu Dhabi to meet its president, Sheikh Mohamed bin Zayed al-Nahyan, and other UAE officials. It was the American president’s third stop of a Gulf tour this week that he says has raised trillions of dollars in investment for the US.
