Anthropic IPO documents show that cloud channel revenue accounts for 48%

According to a report by Financial Associated Press, based on the IPO filing released by Anthropic on Monday, sales generated from the cloud markets of the three major cloud service providers—Google, Amazon, and Microsoft—accounted for 48% of Anthropic's total revenue in the first half of 2026, up from 11% in 2023. These cloud service providers collect payments from customers and transfer them to Anthropic after deducting fees, with payments to channel partners increasing by $2.7 billion year-on-year in the first half of this year. The document shows that Anthropic's sales in the second quarter were $11.555 billion, with an operating profit of $974 million.

The S-1 describes the aforementioned cloud service providers as simultaneously acting as investors, customers, distribution partners, and competitors, stating that they can understand Anthropic's pricing and commercial terms. It also mentions that these companies may prioritize promoting their own AI models, raising antitrust concerns. The document lists the minimum commitments for computing power as follows: at least $114.5 billion to Google by 2033, at least $110 billion to Amazon by 2036, and $44.9 billion to Microsoft; the minimum commitments remain valid regardless of whether the computing power is actually used. Additionally, it is expected that between 2028 and 2031, $125 billion to $150 billion will be paid for additional TPU computing power.

In terms of equity, Amazon and Google currently hold shares without voting rights and are not included in the list of securities with more than 5% voting rights; after the IPO conversion, both will exceed 5% ownership of preferred shares and certain convertible notes. Amazon has invested approximately $18 billion to date and has committed to invest up to an additional $15 billion under specific conditions, with related notes convertible into a maximum of 1.84 billion shares, equivalent to 10.9% of fully diluted shares as of June this year, and subject to a 12% ownership cap. Google has invested approximately $23 billion and has committed to invest an additional $20 billion upon meeting certain conditions, with the latest agreement having a maximum ownership cap of 14.99%. The document also lists a $161.2 billion equipment leasing agreement related to Broadcom, as well as a computing power procurement arrangement with SpaceXAI for up to $120.5 billion.
