Coreweave Helios is an operational AI data center with AI chips owned by CoreWeave and possibly used by OpenAI. It hosts an estimated 160k H100-equivalents of compute, supported by 132 MW of IT power at a capital cost of $5.0 B. In Q1 2029, we project it to rise to 638k H100-eq compute, 528 MW IT power and a cost of $20.0 B. We estimate that it uses Nvidia B200 chips.

The timeline of IT power and compute capacity is based on satellite imagery, our cooling equipment power model, company disclosures, and regulatory filings.

Helios is retrofitted from a former crypto-mining site owned by Galaxy, which has an additional 2.7 GW of capacity under study, though not expected before 2029.
