TeraWulf Signs $19 Billion AI Data Center Lease With Anthropic
The infrastructure firm pivots from Bitcoin mining to support Anthropic's AI scale in Kentucky.
TeraWulf has signed a massive 20-year lease agreement with AI developer Anthropic to build a high-capacity data center campus in Kentucky. The deal marks a significant strategic shift for the infrastructure provider as it moves away from its roots in cryptocurrency mining to support the growing demands of generative AI.
The agreement is valued at approximately $19 billion over its two-decade term. Located at TeraWulf's Justified Data site in Hawesville, Kentucky, the facility is designed to support 401 MW of critical IT load. According to the company, the first power delivery for the site is expected in late 2027.
The Pivot to AI Infrastructure
TeraWulf has historically operated as a Bitcoin mining company, a sector characterized by high power requirements but volatile revenue streams. By leveraging its existing expertise in power procurement and site management, the company is now repositioning itself as a provider of specialized high-power infrastructure. This transition is specifically aimed at supporting the massive computational needs of Large Language Models (LLMs), such as those developed by Anthropic, the creator of the Claude AI.
Industry Implications
This partnership underscores the immense infrastructure pressure created by the global AI race. For AI labs like Anthropic, securing stable, high-capacity power is a critical bottleneck for scaling model training and inference. For the broader market, the deal highlights a growing "crypto-to-AI" trend. Bitcoin miners are increasingly repurposing their power-dense sites to serve as AI data centers, which typically offer more stable, long-term financial returns through corporate lease agreements compared to the speculative nature of digital asset mining.
Market Reaction and Outlook
Investors reacted sharply to the news, with TeraWulf's stock surging more than 26% in pre-market hours following the announcement. The move signals a broader industry realization that the physical layer of the AI stack—power and cooling—is becoming as valuable as the software itself. Observers will now watch for the actual construction milestones in Hawesville to see if the project meets its late 2027 power delivery target.
