He added that the company’s strategy is centered on owning and operating critical infrastructure, maintaining direct relationships with customers and controlling the long-term evolution of its campuses.
This Model Differs Significantly from the Previous Abernathy JV
TeraWulf and Fluidstack created the Abernathy venture in 2025 to develop a 168-MW critical IT load campus on approximately 120 acres near Abernathy, Texas. The project’s total utility requirement has been described as approximately 240 MW.
Fluidstack committed to a 25-year lease at the campus, with Google providing approximately $1.3 billion of credit support for Fluidstack’s obligations. TeraWulf acquired a 50.1% interest in the joint venture through an investment of approximately $450 million. The project subsequently issued $1.3 billion in senior secured notes to support construction and related expenses.
The Abernathy agreements were expected to produce approximately $9.5 billion in contracted revenue for the joint venture over the initial 25-year term. Construction has been advancing toward delivery during the second half of 2026. Following the sale, Fluidstack and the other purchasers will control the project.
TeraWulf agreed to sell its Abernathy interest for approximately $530 million, compared with its $450 million investment in the joint venture. The consideration is scheduled to be paid in three installments through April 2027, with the proceeds expected to support investment in infrastructure opportunities that TeraWulf intends to own and operate directly.
The decision does not necessarily indicate that TeraWulf has become less interested in partnerships with Fluidstack. Fluidstack remains an important tenant at TeraWulf’s Lake Mariner campus in New York, and the companies have built a substantial pipeline of AI infrastructure together.
In infrastructure terms, TeraWulf is acting as both developer and capital allocator. It originated the Abernathy project, helped secure the customer and financing structure, advanced construction and is now monetizing its interest before the campus begins full operations. As the sale proceeds are received, the capital can be redirected toward sites such as Justified Data, where TeraWulf expects to maintain direct ownership and operational control.
Industrial Reuse Becomes an AI Development Strategy
The Hawesville project extends an operating strategy Data Center Frontier examined during a recent visit to TeraWulf’s Lake Mariner campus in Barker, New York.
As DCF previously reported, Lake Mariner occupies the site of a retired coal-fired power plant and is being transformed into a large AI and high-performance computing campus. The location retains two 345-kV transmission lines, substation assets and other electrical infrastructure originally built to support industrial-scale power generation. TeraWulf expects the campus ultimately to support as much as 750 MW of capacity.
TeraWulf executives told DCF that the company is deliberately targeting brownfield industrial properties that either generated or consumed substantial quantities of electricity. Such sites frequently include many of the assets that have become the most difficult and time-consuming elements of new data center development: high-voltage transmission access, large substations, industrial zoning, water infrastructure, utility rights-of-way and community familiarity with heavy industrial operations.
During DCF’s Lake Mariner tour, TeraWulf COO and CTO Nazar Khan specifically cited the Kentucky smelter site as an example of the company’s broader approach.
“For forty years that facility consumed roughly 480 megawatts continuously,” Khan told DCF. “It already had five independent transmission lines for redundancy.”
“If you tried to recreate that infrastructure today, the capital expenditure would be enormous,” he added.
TeraWulf closed on the Hawesville acquisition in February and announced the Anthropic commitment roughly five months later, providing commercial validation of its strategy. Although extensive due diligence and customer discussions likely preceded the closing, the speed between acquisition and lease announcement highlights the strategic value of controlling a power-ready industrial location.
For AI developers, the attraction is not merely cheaper real estate. It is the opportunity to address the time-to-power problem. Across North America, proposed hyperscale and AI campuses are encountering utility interconnection studies, transmission constraints, generation shortages and equipment lead times that can delay projects by several years.
A site with existing high-voltage connections and a history of operating as a 400- to 500-MW industrial load begins from a materially different position than an undeveloped parcel seeking an entirely new utility service.
The product changes, but the underlying infrastructure logic remains recognizable: concentrate enormous amounts of energy at an industrial site and convert that energy into a valuable output.
A $19 Billion Contract, With Qualifications
The headline figure attached to the Anthropic lease is approximately $19 billion in revenue over 20 years. Dividing the headline contract value by the initial 20-year term produces a simple average of approximately $950 million annually. That is not necessarily the project’s stabilized annual revenue, however, because rent begins as individual phases are delivered and the revenue profile will reflect contractual escalators, operating terms and other lease provisions.
TeraWulf will still have to finance and construct the campus, purchase or coordinate the delivery of electrical and mechanical systems, meet Anthropic’s technical specifications and operate the infrastructure over the life of the agreement.
At 401 MW of critical IT load, the capital requirement will be substantial.
TeraWulf has already arranged financing capacity associated with Hawesville. In March 2026, the company entered a $500 million delayed-draw senior secured bridge facility whose proceeds could be used to finance construction at the site. The company has also raised capital through securities offerings as it builds its multi-campus HPC platform.
The investment-grade credit support expected behind Anthropic’s rent obligations should make the project more financeable. Long-term leases with creditworthy tenants are generally essential to securing construction loans, private credit, project bonds or other forms of infrastructure capital.
Nevertheless, execution risk remains significant.
The former smelter site must now be converted into an operating data center. That will require the coordinated delivery of switchgear, transformers, cooling systems, generators, network infrastructure and construction labor before the IT equipment can be installed.
Supply-chain timing remains particularly important for transformers, medium- and high-voltage equipment, chillers, cooling distribution systems and backup-power components. This means that TeraWulf’s experience at Lake Mariner could become an important advantage.
At that campus, the company has worked with Schneider Electric and Motivair on more than $290 million of power, monitoring and liquid-cooling infrastructure. The deployment includes Galaxy VX uninterruptible power supplies, lithium-ion battery systems, coolant distribution units, in-rack manifolds, rear-door heat exchangers and EcoStruxure monitoring software.
What the Transactions Signal for the AI Data Center Market
The Anthropic lease and the Abernathy sale highlight several significant developments in the AI infrastructure sector.
First, AI companies are increasingly seeking dedicated campuses rather than incremental capacity in traditional multitenant data centers.
Second, power-secured sites are becoming financial assets in their own right.
Third, the transactions demonstrate the growing role of capital recycling.
AI infrastructure developers cannot indefinitely retain every project they originate. The cost of building several hundred megawatts at multiple campuses can quickly exceed the balance-sheet capacity of even well-funded public companies.
By selling its interest in Abernathy, TeraWulf can monetize the value created through the project, simplify its reporting and redirect capital toward assets it considers more strategically valuable.
TeraWulf does not describe its primary advantage as access to metropolitan fiber routes, enterprise customers or conventional colocation markets. Its strategy begins with electricity: where large loads can connect, how quickly they can be energized, and which existing industrial assets can be repurposed.
That energy-first model is increasingly relevant as AI campuses grow from tens of megawatts to hundreds of megawatts and, in some proposed developments, multiple gigawatts.
The Next Test Is Execution
The Justified Data announcement gives TeraWulf a marquee AI customer, a 20-year revenue framework and a path toward establishing western Kentucky as a major AI infrastructure market.
TeraWulf must deliver the first capacity during the second half of 2027 and complete the 401-MW ramp by early 2028. The schedule leaves little margin for delays in equipment procurement, utility work, construction or customer deployment.
The project will test whether TeraWulf can reproduce the industrial redevelopment model now underway at Lake Mariner on a larger, customer-dedicated basis.
