Nineteen billion dollars over twenty years. That’s what Anthropic just committed to a company that, not long ago, was grinding out bitcoin block rewards in rural Kentucky. TeraWulf, a vertically integrated miner squeezed by bitcoin’s prolonged price slide, announced on July 6 that it signed Anthropic to a two-decade lease for 401 megawatts of critical AI infrastructure at its Justified Data campus in Hawesville. The site? A former Century Aluminum plant. The pivot is complete.
From Mining Rigs to AI Real Estate
Securing transmission capacity and grid interconnections can take years — TeraWulf already had both, and that head start made all the difference.
Pre-securing massive power contracts before the AI infrastructure rush is like locking in runway slots before a new airport opens. Those are the slow, expensive, unglamorous parts of hyperscale data-center development — and TeraWulf had them ready. Initial capacity comes online in the second half of 2027, ramping to the full 401 MW by early 2028.
- 20-year lease generating approximately $19 billion in contracted revenue, or roughly $950 million per year at about $2.37 per watt — a premium to typical colocation pricing
- 401 MW of critical IT load, phased across multiple build stages
- Anthropic holds two successive five-year renewal options
- TeraWulf stock jumped more than 16% in pre-market trading on the announcement, up approximately 85% year-to-date
Simultaneously, TeraWulf is selling its 50.1% stake in the 168 MW Abernathy, Texas joint venture to a Fluidstack-led investor group for roughly $530 million, monetizing a $450 million investment at a premium. That capital gets redeployed into wholly owned AI compute capacity projects. TeraWulf’s total leased portfolio now sits at approximately 839 MW. “Establishes a long-duration revenue stream with one of the world’s leading AI companies.” — TeraWulf CEO Paul Prager
The Miner Exodus Nobody Saw Coming
Bitcoin’s sustained margin pressure has pushed the entire mining sector toward a fundamental reinvention.
While TeraWulf still mines bitcoin “opportunistically,” according to its 2025 annual filing, high-performance computing is now the primary growth engine. The company isn’t alone in this career change. CoinShares estimated that public miners could derive up to 70% of revenue from AI and HPC by end of 2026, versus roughly 30% previously. Bitdeer reported zero bitcoin held on its balance sheet — selling every coin it mines and redirecting proceeds into AI infrastructure. Call it the Great Mining Migration.
Skeptics have a point, though. Betting 401 MW on a single tenant over twenty years carries real concentration risk. Technology shifts fast, and more efficient AI models could reshape compute demand well before 2046. But Anthropic’s investment-grade credit profile and the genuine scarcity of purpose-built, large-scale AI facilities explain the premium pricing — and why independent analysts frame Anthropic’s commitment as a signal that leading AI labs will increasingly lock in dedicated capacity outside traditional hyperscalers.
The boundary between crypto infrastructure and AI cloud is dissolving. The miners who bet on power access over bitcoin price are now building AI’s physical backbone — either brilliant foresight or the best pivot since Netflix dumped DVDs.
