(Reuters) -OpenAI and Oracle will develop another 4.5 gigawatts of data center capacity, expanding a tie-up that has promised hundreds of billions of dollars in infrastructure investment to keep the U.

The huge deal with Oracle marks a major step forward in OpenAI's journey to 10 gigawatts, as outlined in its four-year, $500 billion Project Stargate strategy. OpenAI confirmed its first site, Stargate I, will be located in Abilene, Texas, with Oracle and OpenAI jointly building it.
