(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 Wall Street Journal reported today that OpenAI and Softbank have not been able to agree on key issues regarding the partnership, including where to build the new sites. The group is now aiming to open a single, smaller data center, likely in Ohio, by the end of the year, according to sources familiar with the matter.
