Meta Hyperion is an AI data center under construction in Holly Ridge, LA, USA, with AI chips owned and used by Meta. No IT power is online yet; it is projected to host an estimated 3,694k H100-equivalent chips — supported by 1,676 MW — at a capital cost of $63.5 B. The timeline of IT power and compute capacity is based on satellite imagery, regulatory filings, grid operator data, our cooling equipment power model, chip availability, and chip efficiency. Meta Hyperion sits on an enormous tract of land — more than three times the size of New York City’s Central Park — and is set to be Meta’s next flagship AI cluster after Prometheus.
