Apollo and Blackstone Secure $36B AI Debt Deal for Anthropic
What's the deal? Apollo Global ManagementDealroom has a profile for this one. Try Dealroom → and Blackstone are providing AnthropicDealroom has a profile for this one. Try Dealroom → with a $36B private credit facility — the largest infrastructure debt transaction in tech history. Rather than raising more equity, Anthropic will use the debt to lease Google's custom Tensor Processing Units (TPUs), housed across four planned hyperscale data centres in the US. Broadcom is backstopping the $31B senior tranche with a residual-value guarantee on the chips, meaning it would absorb the hardware if Anthropic defaults.
Why now? The capital required to train frontier AI models has outgrown traditional venture capital. Building and running the compute infrastructure for models like Anthropic's Claude now resembles heavy infrastructure projects — power plants, toll roads, airports — more than typical software development.
Private credit offers Anthropic a way to secure massive compute capacity without further diluting its equity. For Apollo and Blackstone, the deal opens a new asset class: AI hardware as infrastructure debt, attractive to pension funds, sovereign wealth funds, and institutional investors that want exposure to AI's physical backbone without startup-level risk.
What could go wrong? The deal's safety hinges on Broadcom's guarantee and the assumption that TPUs will hold their value. If chip architectures shift rapidly or demand for Google's TPUs drops, that guarantee could be tested. Anthropic also needs to generate enough revenue to service $36B in debt — a tall order for a company still scaling its commercial operations.
Concentrating this much compute in one company's hands also raises questions about market power and the centralisation of AI capabilities.
The signal: Apollo and Blackstone are both classified as investment funds rather than traditional venture capital firms, underscoring how far AI financing has drifted from its startup roots. With Anthropic already at the late growth stage, this $36B debt facility suggests the company is operationally mature enough to service institutional-grade obligations — but it also means the pressure to convert Claude's commercial traction into sustainable revenue just escalated dramatically.
