Anthropic On Monday signed a 20-year lease to use Justified Data Campus in Kentucky. This lease showcases Anthropic’s involvement in data centers in the US with the company planning a major build-out in the country.

The data center is located about an hour southwest of Louisville in Hawesville. Additionally, it will have capacity of around 400 megawatts. Its first power delivery expected in the second half of 2027.

How TeraWulf Will Benefit from the Lease

Through this landmark 20-year lease with Anthropic, TeraWulf secures exceptional financial stability and strategic positioning by adding approximately $19 billion in highly predictable, contracted revenue supported by investment-grade credit. Also, this massive, single-tenant commitment effectively de-risks the entire 401 MW development of the Justified Data Campus. Moreover, it provides immediate long-term validation for TeraWulf’s infrastructure-first business model. Furthermore, anchoring the site with one of the world’s premier generative AI companies dramatically accelerates TeraWulf’s pivot away from volatile Bitcoin mining into high-margin, wholly owned high-performance computing (HPC) and hyperscale AI hosting.

“The Anthropic lease validates our strategy and establishes a long-duration revenue stream with one of the world’s leading AI companies,” CEO Paul Prager said.

Furthermore, TeraWulf also sold its 50% interest in a 168-megawatt data center in Abernathy, Texas to an investor group led by Fluidstack.

Lastly, TeraWulf is a crypto mining company that has pivoted to AI data center infrastructure. Its stock is up more than 80% this year.

Infrastructure and Environmental Strategy

• Power Advantage: The site benefits from robust, pre-existing bulk power transmission infrastructure left behind by the aluminum smelter’s heavy energy footprint.
• Environmental Impact: Designed as a clean technology center with zero chemical discharge, zero direct greenhouse gas emissions, and highly optimized closed-loop cooling configurations that dramatically reduce daily potable water consumption compared to older data center designs.
