Anthropic has struck a deal with Macquarie Asset Management and Singapore’s GIC to launch Theseus Infrastructure, a new venture that will develop, own and lease data centers built specifically to run Claude, the companies announced on August 10.
How the deal is structured
Funds managed by Macquarie Asset Management, together with GIC, will own the platform and fund the majority of the equity for each project, according to a joint announcement from Macquarie. Anthropic will serve as the anchor tenant under long-term lease agreements, with the venture’s initial focus on identifying and developing sites in the United States. Neither side disclosed a total capital commitment or a timeline for when the first facility would open.
The arrangement lets Anthropic lock in the data center capacity it needs to keep scaling Claude without carrying the upfront construction cost on its own balance sheet — a financing pattern that has become common as AI labs bump against the limits of self-funded buildouts. Macquarie brings experience developing large-scale digital infrastructure, while GIC contributes its global infrastructure-investing track record.
Part of a broader compute push
Theseus follows Anthropic’s $10 billion compute deal with the startup Volta and its move to build an in-house chip team, both aimed at reducing reliance on any single supplier as demand for Claude grows. Anthropic has also committed to covering any increase in consumer electricity prices caused by the new facilities, and the companies say the projects are expected to create thousands of construction jobs plus permanent operating roles in the communities where they are built.
