Anthropic Commits Over $100 Billion to Amazon AWS in Cloud Deal
The scale of Anthropic's AWS commitment, if confirmed by an expected IPO prospectus, would rank among the largest single cloud infrastructure contracts disclosed by a US technology company.
Anthropic, the San Francisco-based artificial intelligence company, has committed more than $100 billion to Amazon Web Services as part of a cloud infrastructure agreement, according to reporting by Yahoo Finance. The figure represents a minimum spend obligation to AWS, Amazon's cloud computing division, and additional details about the contract's structure and timeline are expected to be disclosed in an Anthropic IPO prospectus.
Amazon.com, Inc. (ticker: AMZN) has made Anthropic a central partner in its AI strategy. Amazon announced in 2023 that it would invest up to $4 billion in Anthropic, and subsequently increased that commitment. Those equity investments were disclosed through Amazon's public filings with the Securities and Exchange Commission. The $100 billion cloud spend commitment, however, is a separate commercial obligation and runs distinct from the equity stake.
For context on scale: Amazon Web Services reported full-year 2024 revenue of $107.6 billion, according to Amazon's 2024 annual report filed with the SEC. A single customer committing more than $100 billion in cloud spend over any multi-year term would represent a commercially significant counterparty relationship for AWS, though the term length of Anthropic's commitment has not been publicly confirmed as of the date of this article.
An IPO prospectus, if filed, would be submitted to the SEC under the Securities Act of 1933 and would require disclosure of material contracts, related-party relationships, and significant customer or vendor obligations. Because Amazon holds an equity stake in Anthropic, the AWS contract would likely qualify as a related-party transaction requiring detailed disclosure under SEC Regulation S-K. The prospectus has not been filed publicly as of September 6, 2026, and its contents remain unknown until that filing occurs.
Anthropic was founded in 2021 by former OpenAI researchers, including Dario Amodei and Daniela Amodei. The company develops large language models marketed under the Claude brand. Claude models are currently available through AWS's Bedrock platform, which allows enterprise customers to access AI models via API without managing underlying infrastructure.
The strategic logic of the AWS commitment is grounded in compute dependency. Training and running large language models requires substantial GPU and chip resources. AWS provides that infrastructure, and long-term spend commitments are a common mechanism through which cloud providers and large enterprise or AI customers formalize capacity reservations. Microsoft has a comparable arrangement with OpenAI, with Microsoft having invested approximately $13 billion in OpenAI as disclosed in public reporting, while OpenAI relies on Microsoft Azure for its compute needs.
For US investors, the Anthropic-AWS relationship is material to the valuation case for Amazon stock. AWS accounted for 17.5 percent of Amazon's total 2024 net sales of $637.9 billion, per the Amazon 2024 annual report. Operating income from AWS was $39.8 billion in 2024, representing a disproportionate share of Amazon's total operating income of $68.6 billion. A long-duration, large-scale cloud commitment from a major AI firm supports the revenue visibility argument for AWS.
The precise structure of the $100 billion commitment, including annual minimums, term length, pricing mechanisms, and any penalty or exit clauses, is not publicly known. What would reveal those terms is the Anthropic IPO prospectus once filed with the SEC, or any future Amazon quarterly filing that discloses the contract as a material agreement. Neither document existed in the public record as of the publication of this article.
Anthropic's valuation in private markets was reported at approximately $61.5 billion following a funding round in early 2025, based on reporting from multiple financial news outlets at that time. Whether an IPO would be priced above or below that figure depends on market conditions at the time of any offering and cannot be determined from current available data.
The combination of a nine-figure cloud commitment and a pending public offering positions Anthropic as one of the more closely watched potential IPO candidates in the US technology sector heading into late 2026. The SEC filing, when and if it occurs, will be the definitive public record for the contract's terms and the company's financial condition.
