What happened

Key facts

  • Anthropic has a combined compute backlog worth $750 billion across AWS, Google and Microsoft (per ndtvprofit.com).
  • Anthropic’s S-1 does not describe specific steps it plans to take to mitigate the risk, based on what has been disclosed (per ndtvprofit.com).

The brief

Anthropic’s IPO filing warns that the cloud companies it relies on are increasingly treating it as a direct competitor. NDTV Profit reports that the S-1 identifies AWS, Google and Microsoft as the company’s three primary cloud computing partners and flags the competitive tension between them and Anthropic.

The same account says Anthropic has secured a combined compute backlog worth $750 billion across those providers. The filing’s warning and the backlog sit side by side: the company depends on infrastructure from companies it also identifies as potential competitive threats.

NDTV Profit describes the relationships as involving a growing tension, while noting that the filing does not elaborate on specific steps to address the risk. The headlines from Futu and Yahoo Finance and Investing.com describe a separate measure of Anthropic’s reliance: they say Google, Amazon and Microsoft contribute nearly half of its revenue.

Futu’s headline names Google and Amazon, while Yahoo Finance and Investing.com name all three providers. Those headlines do not state the dollar amount of that revenue or explain how the revenue figure relates to the compute backlog. The filing’s concern, as described by NDTV Profit, is that the cloud providers may see Anthropic as a competitor rather than simply as a customer.

The account does not identify particular products, markets or decisions behind that competitive assessment. It says the filing raises the risk but does not set out what mitigation measures Anthropic may pursue.

The disclosed figures therefore describe two distinct aspects of the relationships: a $750 billion compute backlog across the three providers, and headlines reporting that the providers contribute nearly half of Anthropic’s revenue. The S-1 account does not specify how the backlog is divided among AWS, Google and Microsoft, or provide further detail about the revenue figure.

The central issue raised by the filing is how Anthropic’s reliance on cloud infrastructure intersects with the competitive relationship it says is developing. Any next step would depend on what Anthropic discloses about managing that risk; the account provides no specific plan or timetable.

Why it matters

  • The filing highlights a tension in Anthropic’s reliance on cloud providers that are also building competing AI models: those companies control access to the computing capacity needed to train and serve Claude. If their commercial priorities shift, Anthropic could face less favorable access or terms, while customers and developers who depend on Claude could see changes in availability or cost. The filing identifies the risk but, based on the disclosed information, does not spell out how Anthropic would reduce that dependence.

What to watch next

  • Whether Anthropic discloses specific measures to address the cloud-partner competition risk identified in its S-1.
  • Whether Anthropic provides a breakdown of the $750 billion compute backlog across AWS, Google and Microsoft.
  • Whether Anthropic provides more detail about the revenue contribution attributed to Google, Amazon and Microsoft in the headlines.

How we got here

In November 2024, Microsoft announced a partnership with Anthropic that made Claude available through Azure and included a Microsoft investment; the deal added Azure to Anthropic’s existing cloud relationships with Amazon and Google.

Amazon and Anthropic had expanded their partnership in November 2024, after Amazon’s September 2023 announcement of an investment of up to $4 billion and AWS as Anthropic’s primary cloud provider. Google had announced a cloud-computing partnership and investment in February 2023, then disclosed a further investment commitment in October 2023.
