TeraWulf Signs Google Credit Support for Anthropic Data Center Leases

What happened

TeraWulf Inc. (Nasdaq: WULF) filed an 8-K with the SEC on November 4, 2026 disclosing that it entered into three Credit Support Agreements with Google LLC, its subsidiaries Raylan Data LLC and Justified DataPower LLC, and Anthropic, PBC. Under the agreements, Google agreed to backstop certain obligations of Anthropic under three data center leases at TeraWulf's Hawesville, Kentucky campus, according to the filing.

The leases cover approximately 401 MW of critical IT load for high-performance computing, originally signed in July 2026 as a 20-year agreement between Raylan and Anthropic. The filing states that capacity delivery is expected in phases beginning in late 2027 and concluding in the second quarter of 2028, and that Anthropic's rent obligation begins when each data hall is delivered.

The filing also states that Raylan and Anthropic amended the leases in connection with the backstop, and that TeraWulf issued a press release announcing the arrangements, furnished as an exhibit.

The market reaction

TeraWulf shares closed at $10.08 on the event date, down 13.85% from the prior close of $11.70, according to the price data. Volume was 94.1 million shares, about 2.68 times the average volume of 35.1 million.

The provided sources do not state why the stock moved. The filing describes the Google backstop and the lease amendments; it does not address the share price. No explanation for the decline is offered here because none is supported by the sources.

What this means

TeraWulf is a data center company building and leasing high-performance computing capacity. Its business model now centers on signing long-term leases with large technology tenants, rather than the crypto mining it was originally known for. The Hawesville campus is the site of this lease.

A credit support agreement is a guarantee-like arrangement: a third party — here Google — agrees to stand behind a tenant's payment obligations so the landlord is not solely exposed to the tenant's credit. In this case, Google's backstop becomes effective when the final data hall under each lease is delivered, and terminates once Anthropic, or an affiliate guaranteeing it, achieves and maintains investment-grade credit ratings for at least three months.

If Anthropic misses a payment or faces insolvency, the filing says Raylan can notify Google, and Google then has the option to pay the rent due and take over the lease as tenant, or in certain circumstances pay a termination fee and become entitled to an equity interest in Raylan. The termination fee amortizes over a defined term. This structure matters to a landlord because it substitutes a large, highly rated counterparty's backing for the rent stream during the early, pre-credit-rating period of the lease.

A Form 8-K is the SEC form public companies use to report material events between quarterly and annual reports. Item 1.01 covers entry into material definitive agreements, Item 7.01 is a Regulation FD disclosure used when a company publicly releases information, and Item 8.01 covers other events. TeraWulf used all three here. The 20-year lease term and the phased delivery schedule mean the rental revenue is expected over decades, not immediately; the filing ties the start of rent to delivery of each data hall.
