Buildings 1-14 operational. Buildings 1-4 will likely take over 2 years on this site. By comparison, Buildings 1-7 at the New Carlisle site were completed in less than 1.5 years. Assuming a similar pace, we expect 10 additional buildings to take about 2 years after 2025-09-21. This aligns with [expected completion by 2027](https://www.datacenterdynamics.com/en/news/aws-confirmed-as-company-behind-10bn-mississippi-data-center-development/) and a [permit review document](https://opc.deq.state.ms.us/get_doc.aspx?dt=eparat&id=1747289) from 2025-06-25 for this site, stating the project will take “years” to build.

Notes
Amazon Ridgeland is similar to other Amazon locations, forgoing most external cooling infrastructure in favor of direct air based cooling. We believe it is plausibly part of the Anthropic-Amazon Project Rainier collaboration, based on the New York Times reporting that there’s at least one such data center in Mississippi, though Amazon's data center in Canton is also there.
