CoreWeave Marble NC is an operational AI data center with AI chips owned by CoreWeave and used by OpenAI (speculative). It hosts an estimated 79k H100-equivalents of compute, supported by 65 MW of IT power at a capital cost of $2.5 B. We estimate that it uses Nvidia B200 chips.

The timeline of IT power and compute capacity is based on satellite imagery and company disclosures.

Marble is a former crypto-mining facility that Core Scientific converted to dense GPU hosting, handing the full contracted 65 MW to CoreWeave by May 2026.
