Anthropic Gets Its Own Data Center Fleet — Macquarie and GIC Are Footing the Bill

Anthropic, Macquarie Asset Management, and GIC announced Theseus Infrastructure on August 10 — a new platform that will develop, own, and lease data centers to Anthropic under long-term agreements, with Anthropic as anchor tenant across every facility. It’s a financing structure, not a construction announcement: funds managed by Macquarie and Singapore’s GIC own the platform and cover the majority of equity for each project, while Anthropic commits to the compute lease and to covering the local costs its buildout creates.

That second part is the detail worth reading twice. Anthropic pledged to pay 100% of grid-upgrade costs tied to its sites and to cover consumer electricity price increases that nearby residents would otherwise absorb. Data center power draw pushing up local utility bills has become one of the sharpest political liabilities in the AI buildout — Amazon’s 7.65GW gas plant in Texas drew exactly this criticism this week — and Anthropic is pricing that liability into the deal upfront rather than fighting it in local hearings later. The venture starts by identifying and developing new US sites, with development expected to create thousands of construction jobs and permanent operational roles in host communities.

The structure itself is now the industry’s default playbook: an AI lab that needs guaranteed compute capacity but doesn’t want data center construction and real estate on its balance sheet partners with asset managers who do. Microsoft, OpenAI, and Meta have all cut similar deals over the past 18 months, financing gigawatts of capacity through special-purpose vehicles rather than direct capex. Anthropic’s move follows its own chip-design hiring push from earlier this week — a company that’s simultaneously trying to cut its Nvidia dependency on the compute side and lock in dedicated power and floor space on the infrastructure side.

No dollar figure was disclosed, which is itself notable given how routinely these deals now get announced with headline numbers attached — Nvidia put a $500 billion figure on its own financing partnership announced the same week. What’s clear is the direction: every frontier lab is racing to secure physical capacity years ahead of when models will actually need it, and the entities writing the checks are increasingly pension funds and sovereign wealth vehicles, not the labs themselves.
