Anthropic Gets $35 Billion AI Capacity Boost Backed by Apollo, Blackstone and Broadcom

Anthropic, the AI safety company behind the Claude family of large language models, has secured a massive $35 billion expansion of its artificial intelligence computing capacity through a major new deal involving Apollo Global Management, Blackstone, and chip giant Broadcom.

According to reports from Reuters and The Information, Apollo will lead an initial commitment of $35 billion to fund the expansion, with Blackstone also participating. The capital will be used to build out Anthropic's AI infrastructure using Broadcom's custom chips and networking solutions — a significant vote of confidence in both Anthropic's long-term prospects and the continued growth of AI demand.

The deal represents one of the largest private financing arrangements ever assembled for an AI company and underscores the extraordinary appetite among institutional investors to gain exposure to the AI infrastructure buildout. Broadcom has emerged as a key beneficiary of this trend, providing the custom silicon that powers next-generation AI workloads for hyperscalers and AI labs alike.

This comes as Anthropic prepares for its own initial public offering, having confidentially filed IPO paperwork in recent weeks alongside rival OpenAI. The $35 billion capacity commitment is likely intended to demonstrate to future public market investors that Anthropic has the infrastructure backbone to compete at the frontier of AI development.

The partnership also signals a shift in how AI companies are being financed — moving beyond traditional venture capital rounds and toward large-scale structured deals with asset managers who can deploy capital at the scale the AI arms race demands.
