OpenAI is scaling up its plans with Oracle. Meanwhile, questions remain about Softbank's involvement in the Stargate AI project.

Oracle, SoftBank, and OpenAI will create a new company called Stargate that will build and grow AI infrastructure in the United States.

Oracle and OpenAI expand Stargate project with 4.5 gigawatts of data center capacity, part of a $500 billion U.S. AI infrastructure investment creating over 100,000 jobs.

Oracle is a natural partner as it is already one of the biggest data center operators in the U.S., while SoftBank has the money required to finance ambitious infrastructure projects.
