New Carlisle, Indiana, United States
Anthropic-Amazon New Carlisle is an operational AI data center in New Carlisle, IN, USA, with AI chips owned by Amazon and used by Anthropic. It hosts about 687k H100-equivalent chips, scaling toward a projected 1,748k H100-equivalent chips — supported by an estimated 1,092 MW of IT power, rising to 2,310 MW — at an estimated capital cost of $34.5 B, rising to $72.9 B. We estimate that it uses Amazon Trainium2 chips. The timeline of power and compute capacity is based on satellite imagery, regulatory filings, chip efficiency, and third-party reporting. New Carlisle is part of the Anthropic–Amazon Project Rainier collaboration and, like many other Amazon data centers, forgoes external cooling infrastructure in favor of direct air-based cooling.

Roof complete on building 11
Buildings 1-7 are operational. Based on all of the roofs being completed for over 5 months.
Roof complete on building 16. Generators are being installed for buildings 8-15. In the north, Building 17 and 18 are under construction. To the south of buildings 8-16, a concrete pad is visible, and an expanded car park next to it.
Confirmation that nearly 500,000 chips are operational, which fits buildings 1-7. In an interview, AWS CEO says "they're already running...about 500,000 [Trainium2] chips in Indiana today".
Buildings 8-11 are operational, given it's been over 7 months since their roofs were complete, and the backup generators and roof chimneys look complete. The roof is almost complete for Building 17 and 18.
Buildings 12-16 still have a few generators that look incomplete, so they are unlikely to be operational just yet. Buildings 17-18 still have ongoing roof work, no generators. Just south of Buildings 9-16, the outlines of a site for Buildings 19-32 are taking shape.
Buildings 12-16 are operational. Based on how long previous buildings took, when they were in a similar state to Buildings 12-16 in December.
Buildings 17-18 fully roofed but still having surrounding generators/cooling under construction. Cleared land for buildings 19-32 is still bare, with no building foundations visible yet. Based on satellite imagery.
Buildings 17-18 are operational. This is an estimate based on a rule of thumb of "operational 5 months after roof is complete", assuming the roofs took one more month after 2025-12-23. Also added four more months to account for commissioning and adjacent cooling units not being complete yet.
Buildings 19-32 are operational. This is an estimate based on how long Buildings 1-16 took to become operational. In May 2026, the foundation of several buildings and a substation was visible at the site of Buildings 19-32. Buildings 1-16 took 1 year and 10 months to go from a similar state to operational. So we add 1 year and 10 months to May 2026 to get this date estimate. The power capacity is based on an air quality permit filed in May 2026, and the compute capacity is based on Trainium3 chips.
