Key facts
- Site: TeraWulf's Justified Data campus in Hawesville, Kentucky; up to 401 MW reserved for Anthropic
- Contract term: 20 years; $19 billion in expected contracted revenue for TeraWulf
- Timeline: initial capacity online in H2 2027, full 401 MW build-out targeted by early 2028
- TeraWulf shares surged as much as 18% on announcement day, July 6
- TeraWulf pivoted from Bitcoin mining to AI-focused sustainable computing, and this deal confirms the transition as commercially viable
Why it matters
Securing owned or long-term-leased compute at scale is increasingly a competitive moat in frontier AI — the companies that lock in capacity now avoid spot-market pricing volatility as demand for AI inference grows. For Anthropic, the deal is a major step toward compute independence, reducing reliance on hyperscaler pricing and giving the company predictable cost structure as Claude's usage expands. The 2027–2028 activation window aligns with the projected surge in agentic AI workloads.
