TeraWulf's CEO Leases Land to His Own $3.2B Data Center

TeraWulf’s Lake Mariner campus in the Town of Somerset, New York, reads on paper like a straightforward public-company project. It is not. SEC filings show TeraWulf, the Nasdaq-listed operator, leases the 157 acres under the campus from Somerset Operating Company LLC, a subsidiary of Riesling Power LLC, an entity whose sole member is a revocable trust that TeraWulf’s own chairman and chief executive, Paul Prager, runs as sole trustee. The landlord and the tenant answer, in practice, to the same person, even as coverage of the site’s $3.2 billion in financing draws national attention this month after a fire exposed how many separate companies actually stand behind the project.

Why it matters

For developers and construction firms pricing land or courting a joint venture near a hyperscale campus, the paperwork rarely names who is really on the hook. At Lake Mariner, the visible operator is TeraWulf, the visible tenant is the UK compute firm Fluidstack, and the AI demand comes from Anthropic and other customers buying capacity through Fluidstack. But the ground lease sits inside a CEO-controlled holding company, and the financial backstop behind Fluidstack’s lease payments, the number that actually makes the deal bankable, comes from Google. That layering is standard practice in this asset class now, and it means the entity signing a permit application or a utility interconnection filing is often several steps removed from the party actually capitalizing the build.
