Anthropic Signs ~$19B 20-Year Data Center Lease With TeraWulf in Kentucky

TLDR

TeraWulf on July 6, 2026 said it signed a 20-year lease with Anthropic for AI infrastructure at the Justified Data campus in Hawesville, Kentucky, a deal expected to produce roughly $19 billion in contracted revenue. Capacity is about 401 megawatts of critical IT load; first power is targeted for second half of 2027, full build by early 2028. Shares jumped on the news.

Deal terms

From TeraWulf’s investor press release and Reuters/CNBC:

• Tenant: Anthropic.
• Term: 20 years.
• Revenue expectation: ~$19 billion contracted (TeraWulf estimate).
• Site: Justified Data campus, Hawesville, KY (former industrial/aluminum-area redevelopment context in coverage).
• Scale: ~401 MW critical IT load.
• Timeline: Initial capacity H2 2027; full capacity early 2028.
• Related: Same announcement included TeraWulf’s sale of a majority interest in the Abernathy joint venture to Fluidstack.

Why this story matters

Frontier labs are locking decades-long power-and-shell contracts far from the coasts. A ~$19B Anthropic–TeraWulf lease is another data point that Claude-scale compute is a multi-year industrial build—not a quarterly GPU buy—and that “neocloud” operators can re-rate on single lab anchors.
