### The Numbers That Matter: A 401 MW Commitment
The Anthropic lease covers a purpose-built AI infrastructure campus at TeraWulf's **Justified Data site** in Hawesville, Kentucky, located about an hour southwest of Louisville . Here are the key details:
| Metric | Value |
|--------|-------|
| **Lease Term** | 20 years |
| **Capacity** | ~401 MW of critical IT load |
| **Total Revenue (Initial Term)** | ~$19 billion |
| **Annual Average Revenue** | ~$950 million |
| **Renewal Options** | Two 5-year options (up to 10 additional years) |
| **First Capacity Online** | H2 2027 |
| **Full Build-out** | Early 2028 |
| **Payment Support** | Expected to be backed by investment-grade credit |
The campus will be developed in multiple phases. Initial capacity is slated for the second half of 2027, with the full 401 MW ramp-up expected by early 2028 . Anthropic also holds two successive five-year renewal options, which could extend the relationship to **30 years** .
"This lease validates our strategy and establishes a long-duration revenue stream with one of the world's leading AI companies," said TeraWulf CEO Paul Prager . "When we announced the Justified Data campus acquisition in February, we told investors that we expected to secure a major customer commitment by around the end of the second quarter of 2026" .

### From Bitcoin Mining to AI Infrastructure
The Anthropic lease represents a significant milestone in TeraWulf's ongoing transformation. The company, which originally operated as a Bitcoin mining company, has been pivoting to AI data center infrastructure as the demand for AI computing power has exploded .
Companies like TeraWulf realized there was a booming market for the digital infrastructure and data centers they used for their own operations, and began leasing them out to AI developers . The Justified Data campus, acquired from a Century Aluminum subsidiary in February 2026 for $200 million plus a minority equity interest, now has a marquee tenant .
The lease also represents a sharp increase in TeraWulf's contracted AI capacity. As of March 31, the company's Q1 investor presentation showed 522 MW of contracted capacity across its entire platform, with the Justified Data site listed at zero MW contracted. The 401 MW Anthropic lease **roughly doubles** the company's contracted load in a single transaction .

### A Related Move: Exiting Abernathy
In a separate but related transaction, TeraWulf announced it is selling its **50.1% controlling interest** in the Abernathy Joint Venture—a 168 MW AI data center campus in Abernathy, Texas—to an investor group led by its joint venture partner, Fluidstack .
The sale monetizes TeraWulf's roughly **$450 million investment** at a premium to invested capital, with total consideration of about **$530 million** payable in three installments :
| Installment | Amount | Due Date |
|-------------|--------|----------|
| 1st | $250 million | Within 14 days of signing |
| 2nd | $150 million | On or before Dec 31, 2026 |
| 3rd | ~$130 million | On or before Apr 30, 2027 |
"This sale crystallizes the value created through that investment and generates significant capital for redeployment into infrastructure platforms where we maintain direct ownership, customer relationships, and operational control," Prager said .

### AI Demand Is Insatiable
The TeraWulf-Anthropic deal is the latest in a series of massive infrastructure commitments by leading AI labs. Anthropic has been aggressively securing computing capacity, including a **$50 billion deal** with Fluidstack to build custom data centers in New York and Texas .
The demand for AI computing power shows no signs of slowing, and companies that can provide the necessary infrastructure—power, land, and connectivity—are increasingly valuable. TeraWulf's stock had gained about 85% year-to-date even before Monday's pop .
