OpenAI Stargate Wisconsin

Port Washington, Wisconsin, United States

OpenAI Stargate Wisconsin is an AI data center under construction with AI chips owned by Oracle and used by OpenAI. In Q4 2028, we project it to host an estimated 2,628k H100-equivalents of compute, supported by 902 MW of IT power at a capital cost of $34.2 B.

The timeline of IT power and compute capacity is based on satellite imagery, company disclosures, regulatory filings, and chip efficiency.
