Google agreed to support Anthropic’s lease obligations at TeraWulf’s Kentucky campus, strengthening its bid for project financing. The support starts after delivery milestones, while debt terms and a guaranteed construction price remain unsettled.
Google’s support covers specified Anthropic lease obligations and takes effect after delivery milestones.
The roughly $19 billion represents contracted lease commitments over 20 years; it is not the project’s construction cost or announced borrowing.
A definitive Fluor construction agreement adds execution capacity, but guaranteed maximum pricing is still being established.
Google agreed on November 4 to backstop certain lease obligations of Anthropic, the developer of the Claude AI assistant, at a planned Kentucky campus of TeraWulf, a U.S. infrastructure operator shifting from bitcoin mining toward AI data centers. The support strengthens the financing framework for approximately 401 megawatts of critical IT capacity at the Justified Data Campus in Hawesville, but becomes effective only after the final data hall under each lease is delivered.

Credit support with a delayed start
TeraWulf develops and operates power-backed digital infrastructure in the United States, including the Lake Mariner campus in New York, where it also operates bitcoin-mining infrastructure. Its business is increasingly shifting toward leasing infrastructure for AI and high-performance computing. The company says it develops the underlying facilities rather than investing in AI computing hardware.
Raylan Data, TeraWulf’s subsidiary and the landlord for three buildings, entered into the 20-year Anthropic lease arrangement in July. Anthropic begins paying rent as individual data halls are delivered, according to the filing.
Google’s backstop starts later: separately for each lease, when the final data hall under that lease reaches its commencement date. Delivery is expected in phases from late 2027 through the second quarter of 2028. The credit agreement therefore does not provide immediate protection throughout construction.
Once effective, a payment default or Anthropic insolvency can require Google to choose between paying rent due and taking over as tenant, or, under specified circumstances, paying a termination fee. Payment of that fee would entitle Google to acquire an equity interest in Raylan. For a payment default, Google can also defer its choice for a specified period while covering unpaid and newly due rent.

That structure gives Google potential control over the leased space or a stake in the landlord if the tenant fails. It also limits the protection’s duration: the termination fee amortizes, and the agreements can end when Anthropic, or a qualifying affiliate guarantor, achieves and maintains specified investment-grade ratings for at least three months. Raylan and Anthropic amended the leases alongside the credit agreements.
A detailed analysis of the agreements identifies another constraint on Google’s exit. During the first six years, Google cannot reject a lease unless installed TPU pods could draw less than 50% of the tenant’s critical power. TPUs are Google’s AI accelerator chips. The analysis also describes a 30-day verification period after a triggering event. These conditions make the installed computing equipment consequential to the backstop’s operation.
The same analysis says that if Anthropic defaults before the backstop starts, Raylan retains the right to complete the premises, and a qualifying default still continuing at effectiveness becomes a trigger. Construction-period tenant risk nevertheless remains with TeraWulf and its lenders until that protection takes effect.
Google is a supplier, investor and competitor
TeraWulf says the support will help it pursue competitively priced long-term debt. Google is an Alphabet subsidiary; TeraWulf’s announcement cites Alphabet’s AA+ senior unsecured rating from S&P Global Ratings and Aa2 from Moody’s. Those are parent-company ratings, while Google LLC is the named credit-support counterparty.
Google’s involvement goes beyond supplying computing capacity. In its 2024 review of their partnership, the UK Competition and Markets Authority documented Google’s acquisitions of non-voting Anthropic shares and provision of convertible debt. It also identified Google as a supplier of computing and distribution services to Anthropic, while developing the competing Gemini family of AI models. The regulator concluded that the partnership had not given Google material influence over Anthropic at that time.
The commercial relationship has since expanded. In an October 2025 announcement, Anthropic said it planned to expand its use of Google Cloud to as many as one million TPUs, in an expansion worth tens of billions of dollars. It expected well over a gigawatt of capacity to come online in 2026; that was a forecast, not confirmation of delivered capacity.
The relationship is not exclusive: Anthropic described using Google TPUs, Amazon Trainium chips and Nvidia GPUs, and named Amazon its primary training partner and cloud provider.

Operating experience and capital demands
The financing mechanism has precedent within TeraWulf’s own portfolio. In its August operating update, the company said delivery of a Lake Mariner building in early July satisfied conditions for $600 million of Google credit support for Fluidstack’s lease obligations to become effective.
That delivery increased revenue-generating critical IT capacity from 81 MW at June 30 to 102 MW in July. Justified’s planned 401 MW is nearly four times that dated operating base, although TeraWulf also reported another 336 MW under construction at Lake Mariner. These figures describe different stages of development, rather than capacity operating today.
HPC leases supplied $31.9 million of TeraWulf’s $44.8 million second-quarter revenue, approximately 71%, illustrating how far its revenue mix had shifted from mining. But leasing revenue was not yet financing the expansion by itself: company-wide operating activities used $154.3 million of cash in the first half of 2026, while purchases of and deposits on plant and equipment consumed about $1.38 billion.
TeraWulf ended June with approximately $3.03 billion in cash, cash equivalents and restricted cash, including about $409 million of restricted cash. Its balance sheet also carried about $5.21 billion of debt and convertible notes, adding their current and long-term balances. These consolidated, dated figures provide context for its financing capacity; they are not a current funding total for Justified.
The financing and construction tests ahead
The approximately $19 billion headline figure is contracted lease revenue over the initial 20-year term, as described in the report on TeraWulf’s announcement. TeraWulf’s August results said the total could reach approximately $33 billion if Anthropic exercises both five-year extensions. Those optional revenues are separate from the initial commitments.
The project’s nearer-term capital requirement is a different measure. The agreement analysis says TeraWulf estimated site and initial data-hall development at $4 billion to $4.5 billion in August, excluding the tenant’s computing equipment. It also recounts Bloomberg’s July reporting that Patrick Fleury, TeraWulf’s chief financial officer, said the company was preparing about $3.5 billion of debt. Those are an estimated development cost and an earlier borrowing plan, rather than newly closed financing terms.
The site reuses transmission infrastructure at the former Century Aluminum Hawesville facility, and Kentucky regulators approved up to 482 MW of electric service in August, according to the analysis. TeraWulf’s August update also described an energized on-site substation and existing high-voltage transmission. These assets help explain the site’s selection. Utility-service capacity measures a different scope from the 401 MW of critical IT load promised to Anthropic.
TeraWulf has now signed a definitive engineering, procurement and construction agreement with Fluor Enterprises, expanding the engineering and construction firm's March limited notice to proceed into testing and commissioning as well. TeraWulf cites Fluor’s more than a century of infrastructure experience and access to procurement resources, subcontractors and skilled labor as reasons for the partnership. That labor access matters to execution: TeraWulf identifies labor availability as an increasing constraint on large data-center projects.
The contract includes delivery milestones, open-book cost reporting and performance protections. But although structured on a guaranteed maximum price basis, that pricing is still being established as engineering and procurement advance, TeraWulf says.
The next evidence will be the debt actually secured, its price and terms, the completed construction pricing, and delivery against the late-2027-to-second-quarter-2028 schedule. Google’s credit support addresses a defined tenant-payment risk; reaching the milestones that activate it still requires TeraWulf to finance and complete the campus.
