TeraWulf has signed a 20-year lease agreement with Anthropic that is expected to generate approximately $19 billion in revenue, according to an announcement on Monday.

Nearly all bitcoin miners have begun adding AI-related business lines as a way to generate consistent and predictable revenue amid a data center boom caused by AI’s intense compute needs.

TeraWulf's agreement with Anthropic is for a "purpose-built AI infrastructure campus" at its Justified Data site in Hawesville, Kentucky, outside of Louisville, which will be developed in phases.

Initial services are expected to begin in the second half of 2027 and ultimately deliver 401 MW of critical IT load, a significant amount for AI training, by early 2028.
