- Anthropic has committed to spending $200 billion with Google Cloud over five years for TPU and Broadcom-built compute capacity.
- The deal accounts for more than 40% of Alphabet's total cloud revenue backlog, making Anthropic Google's most important infrastructure customer.
- Alphabet is also investing up to $40 billion in additional capital into Anthropic as part of the broader agreement.
Anthropic signed a five-year agreement to spend $200 billion on Google Cloud infrastructure, the largest compute deal in the AI industry's history. The contract covers multiple gigawatts of Tensor Processing Unit capacity, built in partnership with Broadcom, that is expected to come online starting in 2027.
The scale of the commitment reflects a compute crunch that Anthropic has been racing to solve. Surging demand for Claude Code and Cowork, the company's developer and productivity tools, exposed capacity constraints that existing infrastructure could not absorb. Anthropic's annualized revenue run rate now exceeds $30 billion, up from roughly $2 billion eighteen months ago. That growth created urgency: the company needed to secure hardware years ahead of when it would be needed, or risk losing customers to rivals with more available capacity.
For Alphabet, the deal reshapes the economics of Google Cloud. Anthropic's commitment accounts for more than 40% of the cloud backlog Alphabet disclosed to investors last week. When the news broke on May 5, Alphabet's stock rose roughly 2% in extended trading and briefly surpassed Nvidia in market capitalization. Google Cloud, long the third-place hyperscaler behind AWS and Azure, now has a contractual anchor tenant that changes its competitive position.
The agreement also includes a fresh capital injection. Alphabet is investing up to $40 billion directly into Anthropic, adding to the roughly $14 billion Google has already committed to the company since 2023. That brings Alphabet's total financial exposure to Anthropic, through cloud commitments and equity combined, to approximately $254 billion over the next five years.
Anthropic is not placing all its compute with a single provider. The company has also agreed to spend more than $100 billion on AWS over ten years and has expanded partnerships with CoreWeave and Broadcom independently. Taken together, contracts involving Anthropic and OpenAI now account for more than half of the $2 trillion in backlog across the three major cloud providers. The AI industry's two leading model builders have effectively become the largest buyers of cloud infrastructure on Earth.
The deal carries risk for both sides. Anthropic is betting that revenue growth will continue at a pace that justifies $200 billion in committed spending. Google is betting that hosting Anthropic's workloads will not conflict with its own Gemini ambitions. For the broader market, the contract is further evidence that AI compute demand has moved from speculative to contractual, and that the companies willing to lock in capacity at scale are the ones shaping the industry's next phase.
