Google Backstops $19B Anthropic Lease at TeraWulf Campus
Google is credit-backing debt for about $19B of Anthropic's Kentucky data-centre lease at TeraWulf. If Anthropic defaults, Google can take the lease or a stake in the project unit.
About $19 billion of Anthropic’s data-centre rent at a Kentucky campus now has Google standing behind the debt that finances it. Bitcoin miner TeraWulf said the credit backstop is meant to help it raise project financing on leases already signed with the AI lab.
In a 4 November press release, TeraWulf said it executed credit support agreements with Google LLC for debt financing supporting approximately $19 billion of contracted lease commitments with Anthropic at its Justified Data Campus in Hawesville, Kentucky. Google is a subsidiary of Alphabet. Alphabet’s senior unsecured debt is rated AA+ by S&P Global Ratings and Aa2 by Moody’s, the company noted.
What Google can do if Anthropic fails
Secondary coverage of the related SEC filing adds detail the release does not. CoinDesk reported a 20-year lease covering about 401 megawatts of critical IT load. If Anthropic defaults or becomes insolvent, Google can assume the lease. Under certain conditions it can instead pay a termination fee and take a proportional ownership stake in Raylan Data, the project subsidiary — not in publicly traded TeraWulf itself.
That structure is unusual for a hyperscaler. It ties Google’s balance sheet to Anthropic’s rent cheque while giving Google a path into the physical campus if the tenant cannot pay. For lenders, the AA+/Aa2 parent rating is the point: cheaper project debt than a bitcoin miner and a private AI lab could raise alone.
Build schedule and Fluor EPC
TeraWulf also executed a definitive engineering, procurement and construction agreement with Fluor Enterprises on a guaranteed-maximum-price basis for three data centre buildings at Justified. Phased ready-for-service dates are expected from late 2027 through the second quarter of 2028.
The deal sits in a wider fight over where AI capacity gets built. Voters recently blocked AI data centres in 40 of 41 local ballots, even as labs keep signing multi-billion-dollar power and real-estate contracts. Separately, big tech is also trimming spend elsewhere — Apple has cut staff AI budgets as its own costs climb. Investors tracking these capital flows can follow them on terminals such as Kyro, which links 250+ brokers, exchanges and wallets to 100+ AI models.
Why it matters
A $19 billion lease is only as bankable as the credit behind it. Google’s backstop turns Anthropic’s Kentucky rent into something lenders can underwrite against an investment-grade parent, and it gives Google a contingent claim on the project if that rent stops.
