TeraWulf said on November 4, 2026, that it executed credit support agreements with Google LLC to backstop project financing tied to roughly $19 billion in contracted lease commitments with Anthropic at the Justified Data Campus in Hawesville, Kentucky, and that it signed a definitive Fluor EPC agreement for three data center buildings. The $19 billion figure is contracted lease value, not a Google cash grant. The story lands on TBR’s AI Infrastructure hub via the data-centers tag and also carries Business & Finance for the financing angle. Related compute-finance coverage includes Nvidia’s earlier Nscale–Anthropic guarantee discussions.
What Google’s backstop actually does
TeraWulf’s press release says Google provides contractual credit support intended to help the company secure competitive debt financing for the contracted Anthropic leases. Alphabet’s senior unsecured debt ratings cited in the release are AA+ (S&P) and Aa2 (Moody’s). A TeraWulf Form 8-K dated November 4 adds that Google agreed to backstop certain Anthropic lease obligations for buildings CB-1, CB-2 and CB-3, with effectiveness tied to commencement of the final data hall under each lease and with options for Google to pay rent and assume a lease or, in some cases, pay a termination fee after a payment default or insolvency event. Those are contractual descriptions from the filing, not predictions of default.
Lease size, power and schedule
The 8-K states that in July 2026 a TeraWulf subsidiary entered a 20-year lease with Anthropic for about 401 MW of critical IT load at Justified, with phased delivery expected from late 2027 through the second quarter of 2028. Data Center Dynamics reported planned campus capacity of about 480 MW on a former Century Aluminum site. Fluor’s EPC covers three buildings on a guaranteed-maximum-price basis with open-book cost reporting, according to TeraWulf. The chart summarizes the headline lease dollars, power figures and term.
Why infrastructure desks care
AI model demand is colliding with multi-year power, construction and credit structures. Google’s role here is credit enhancement around an Anthropic tenancy, not a statement that Google is the campus tenant. For Kentucky residents and grid planners, the relevant dates are still the 2027–2028 ready-for-service window disclosed by TeraWulf. Readers following data-center politics can also revisit TBR’s earlier ballot-measure reporting on local opposition to large AI campuses.
Numbers to keep straight
Do not conflate (1) $19 billion in contracted Anthropic lease commitments, (2) Google’s unstated notional of the backstop, and (3) Fluor’s construction GMP, which TeraWulf said is still being established as engineering advances. The 401 MW lease load and ~480 MW campus capacity figures likewise answer different questions. TBR’s strip above uses the company and trade-press numbers as disclosed on November 4–5 coverage.
How this compares with other AI compute financings
Large language-model labs have leaned on campus leases, prepaid cloud capacity and vendor credit support to lock multi-year power. TeraWulf’s structure is a landlord-tenant lease with a third-party credit backstop from Google around Anthropic’s obligations, paired with a Fluor build contract. That is different from a simple hyperscaler self-build and different from an equity investment in the landlord. Secondary coverage correctly warns not to read the $19 billion headline as Google writing a $19 billion check.
For Kentucky, the local stakes are construction employment, transmission upgrades and the reuse of an industrial aluminum site. For Anthropic, the stake is scheduled megawatts arriving in 2027–2028. For Google, the stake is contingent credit exposure described in the 8-K. TBR will update if TeraWulf discloses financing close amounts, interest margins or changes to the ready-for-service calendar.
