In a major move to secure long-term computing power, Anthropic has signed a 20-year lease with TeraWulf for a purpose-built AI infrastructure campus in Kentucky. The deal is expected to generate approximately $19 billion in contracted revenue over its initial term.
The announcement, made on July 6, 2026, highlights the intense race among AI companies to lock in massive amounts of power and infrastructure for training and running advanced models.
Key Details of the Anthropic-TeraWulf Deal
- Location: Justified Data campus in Hawesville, Kentucky
- Capacity: Approximately 401 MW of critical IT load for high-performance computing
- Lease Term: 20 years
- Expected Revenue: ~$19 billion over the initial term
- Timeline: Initial capacity expected online in the second half of 2027, with full capacity by early 2028
The campus is specifically designed for AI workloads, reflecting the growing demand for specialized data center infrastructure optimized for large-scale model training and inference.
Why This Deal Matters
1. Anthropic Secures Long-Term Compute Capacity Anthropic (the company behind the Claude AI models) has been rapidly scaling its infrastructure. This long-term lease provides stable, predictable access to significant power capacity — a critical bottleneck in the AI industry.
2. TeraWulf’s Strategic Pivot Pays Off TeraWulf, originally a Bitcoin mining company, has been transitioning toward AI and high-performance computing data centers. This deal validates that strategy and delivers massive contracted revenue, reducing reliance on volatile crypto mining economics.
TeraWulf’s stock surged more than 16% in premarket trading following the announcement.
3. Bitcoin Miners Are Becoming AI Infrastructure Players This is part of a broader industry trend where former Bitcoin miners are repurposing their power infrastructure and expertise for AI data centers. Companies like TeraWulf, Core Scientific, and others are increasingly positioning themselves as key players in the AI power ecosystem.
4. Power Remains the Biggest Constraint in AI Securing hundreds of megawatts of reliable power is one of the biggest challenges facing AI companies. This deal shows how AI firms are willing to sign extremely long-term, high-value contracts to guarantee future capacity.
Additional Context from the Announcement
Alongside the Anthropic lease, TeraWulf also announced it is selling its 50.1% stake in the Abernathy Joint Venture to an investor group led by Fluidstack (another AI infrastructure company) for approximately $530 million.
This move further sharpens TeraWulf’s focus on its core data center and AI infrastructure business.
Broader Implications
- AI Infrastructure Arms Race: Anthropic is making aggressive moves to secure compute, joining OpenAI, Google, Meta, and others in the race for power and chips.
- Long-Term Contracts Becoming Standard: AI companies are increasingly signing multi-year (even 10–20 year) deals to lock in capacity amid tight supply.
- Energy & Infrastructure Focus: The deal underscores how energy availability and data center development have become central to AI progress.
Summary
Anthropic–TeraWulf AI Data Center Deal (2026)
- Tenant: Anthropic
- Landlord: TeraWulf
- Location: Hawesville (Justified Data Campus)
- Capacity: ~401 MW of critical IT load
- Lease Term: 20 years
- Expected Revenue: Approximately $19 billion over the initial lease term
- Initial Capacity: Second half (H2) of 2027
- Full Capacity: Early 2028
- Key Significance: One of the largest long-term AI infrastructure lease agreements announced in 2026, supporting large-scale AI compute expansion.
This deal represents one of the largest single AI infrastructure commitments announced so far in 2026 and signals continued strong demand for power and data center capacity from leading AI developers.
