Amazon Ridgeland is an operational AI data center with AI chips owned by Amazon and used by Anthropic (speculative). It hosts an estimated 171k H100-equivalents of compute, supported by 228 MW of IT power at a capital cost of $8.6 B. In Q3 2028, we project it to rise to 788k H100-eq compute, 840 MW IT power and a cost of $31.8 B. We estimate that it uses Amazon Trainium2 chips.

The timeline of IT power and compute capacity is based on satellite imagery, regulatory filings, chip efficiency, and third-party reporting.

This site is likely part of the Anthropic–Amazon Project Rainier collaboration.
