Anthropic's prospectus discloses: cloud channels contributed 48% of first-half revenue, and it has committed to paying massive compute fees to Google, Amazon, and Microsoft
Anthropic disclosed in its initial public offering filing that its business of distributing Claude through Amazon, Google, and Microsoft cloud accounts accounted for 48% of its revenue in the first half of 2026, far above 11% in 2023. The company posted second-quarter revenue of $11.6 billion and an operating profit of $974 million, but its first-half sales, marketing, and partner costs rose to $3.2 billion from $120 million a year earlier, including $2.7 billion in additional payments to channel partners. The filing also shows that Anthropic has committed to paying Google at least $114.5 billion by 2033, Amazon $110 billion by 2036, and Microsoft $44.9 billion, and it notes that these cloud providers are simultaneously investors, customers, distribution partners, and competitors, a relationship that has already drawn antitrust scrutiny.
