How Google’s credit support underpins TeraWulf’s Anthropic data-centre leases

TeraWulf’s November 4 SEC filing shows how Google’s credit support is intended to help finance a major data-centre development for Anthropic in Kentucky. The company describes 20-year leases covering 401 MW of critical IT capacity at Hawesville and approximately $19bn in contracted customer commitments. The support agreement adds Google to the project’s credit structure, while leaving the timing and form of its obligations dependent on specific contractual conditions.[1][2]

The distinction is financially significant. A long lease can support borrowing against future rent, but lenders also need to know what happens if the tenant cannot pay. Google’s involvement provides an additional route for meeting those obligations after the contractual support becomes effective. The $19bn figure describes Anthropic’s commitments over the lease terms; it does not disclose an unconditional $19bn payment promise by Google.[1][2][3]

When the support starts

TeraWulf expects delivery of the three buildings from late 2027 through the second quarter of 2028. Rent begins as the relevant data halls meet their lease commencement conditions. Google’s principal default-related obligations, however, become effective when the final data hall under the corresponding lease commences. Earlier hall delivery and activation of the full backstop are therefore different milestones.[1][3]

That timing leaves construction and commissioning central to the financing story. Credit support can strengthen the future rental stream, but the campus still has to reach the conditions that activate it. TeraWulf’s announcement describes a guaranteed-maximum-price construction framework with Fluor while noting that pricing is being established as engineering and procurement progress.[2]

The default options have limits

Once the agreement is effective and a qualifying default occurs, the filed form sets out routes for Google to assume the lease and pay rent due, or allow termination and pay a scheduled fee. It also permits a deferral route in specified circumstances. The fee declines over time and is linked to project financing, rather than simply equalling the remaining headline lease value.[1][3]

A further condition appears in the contract itself: during the first six years after the support becomes effective, Google generally cannot elect the termination option unless installed TPU pods are capable of consuming less than 50% of the tenant’s critical power. That restriction gives the early-period arrangement a different shape from a freely exercisable choice between taking the lease and paying to exit.[3]

The filing also says the support can terminate if Anthropic maintains an investment-grade credit rating for three consecutive months. This makes the arrangement responsive to the tenant’s own credit standing, rather than necessarily lasting for the entire 20-year lease term.[1]

What the public contract reveals

The filed exhibit is a form agreement. Its termination-fee schedule is not populated in the public document, and the debt-related cap contains blank amount and percentage fields. The available material therefore establishes the mechanism but does not allow an outside reader to calculate a complete maximum dollar exposure for Google.[3]

The useful finding is the division of risk. TeraWulf must deliver usable capacity; Anthropic is the long-term tenant; Google supplies conditional credit support with defined entry and exit provisions. That can make a large AI campus more financeable, but the strength of the arrangement depends on those provisions and the construction milestones—not on treating the lease headline as cash already guaranteed.[1][2][3]
