Oct 30 (Reuters) - OpenAI, Oracle and Related

Digital said on Thursday they would build a data-center campus

of more than 1 gigawatt in Saline Township, Michigan, as part of

their Stargate push to expand U.S. artificial intelligence

infrastructure capacity.

The project would start construction in early 2026 and is

part of Oracle and OpenAI's previously announced 4.5-GW

expansion under the Stargate program. It brings Stargate to more

than 8 GW of planned capacity and more than $450 billion in

investment over the next three years.

The companies said it was a multi-billion dollar investment,

without disclosing the exact figure. Industry executives have

said 1 GW of computing power, enough to power roughly 750,000

U.S. homes, can cost around $50 billion.

Related Digital will develop the project, which is expected

to create more than 2,500 union construction jobs.

"This project will help ensure Michigan is a key part of

building the AI infrastructure that will power the next

generation of American innovation," said Peter Hoeschele,

OpenAI's vice president of industrial compute.
