Anthropic inks $19B AI data center lease with TeraWulf

Anthropic PBC will pay $19 billion to lease a TeraWulf Inc. data center for 20 years.

TeraWulf, a Nasdaq-listed developer of artificial intelligence infrastructure, announced the deal today. The company’s shares rose 4.8% on the news.

The data center that Anthropic has agreed to lease is currently being built on the site of a former aluminum smelting facility in Hawesville, Kentucky. The 790-acre campus has existing power transmission and fiber-optic infrastructure, which will speed up construction. Building new overhead power lines can take years in some cases.

TeraWulf expects to bring an unspecified amount of “initial capacity” online in the second half of 2027. The facility will become fully operational the following year with 401 megawatts of computing power.
