Anthropic secured a 20-year lease for 401 megawatts of critical IT load at TeraWulf's Justified Data campus in Hawesville, Kentucky, generating approximately $19 billion in contracted revenue. The agreement funds a purpose-built, single-tenant high-performance computing facility for Claude model training and inference, with phased capacity delivery beginning in the second half of 2027. The campus will use a closed-loop liquid cooling system and power is governed by a 15-year pass-through agreement tied to MISO energy and capacity markets.
Anthropic locked in a massive, long-term compute and power supply, shifting significant AI infrastructure risk to TeraWulf and securing capacity for its models.
