A potential partnership with a developer majority-owned by Apollo would provide the AI startup with a dedicated footprint for its server and chip hardware. The ongoing talks with Stream Data Centers involve a lease for up to 1 gigawatt of capacity, a buildout that would require at least $40 billion in capital. Anthropic is considering filling the facilities with Tensor Processing Units from Google and Broadcom or with Nvidia GPUs, while Google has discussed providing a credit guarantee for the project.

The deal represents the largest direct data-center lease the company has ever pursued and marks a move to bypass traditional cloud providers. By controlling the infrastructure, chips, and pricing directly, Anthropic seeks to reduce its dependence on third-party compute rentals. The arrangement is still in early negotiations and would increase the company's operational and financing responsibilities.
