California-based power solutions provider Bloom Energy said it will deploy its fuel cell technology at select Oracle Cloud Infrastructure (OCI) data centers in the U.S. The company on July 24 said it will deliver on-site power for an entire data center within 90 days.

OpenAI was the company that signed a $30 billion per year deal with Oracle for data center services, disclosed last month, The Wall Street Journal reported on Monday. Now, OpenAI CEO Sam Altman has confirmed the details of the contract (but not the dollar amount) in an X post on Tuesday and in a company blog post.

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.S. ahead in the global artificial intelligence race.
