Amazon is investing an additional $5 billion in Anthropic and could commit up to $20 billion more over time, deepening their partnership in an increasingly competitive AI landscape.
Anthropic, the developer of the Claude chatbot and coding tool, plans to spend over $100 billion over the next decade on Amazon’s cloud services and chips, the companies said in a statement on Monday.
Amazon was already among Anthropic’s largest backers, with previous investments totaling $8 billion. For Amazon, the partnership has strengthened its cloud business by providing access to a leading AI model and a major customer for its in-house Trainium AI chips.
Anthropic, in turn, has benefited from access to Amazon’s extensive network of corporate clients. According to the companies, more than 100,000 customers run Claude models on Amazon Web Services.
Anthropic, founded in 2021 by several former employees of OpenAI, is widely expected to pursue an initial public offering as early as this year. The company has been working to attract more paying enterprise customers to help offset the substantial costs of developing its technology.
Anthropic secured a $30 billion funding round in February, valuing the San Francisco–based startup at $380 billion, and has since received investor interest suggesting a valuation exceeding $800 billion.
The agreement highlights Anthropic’s growing demand for the vast computing power required to develop new versions of Claude. Like OpenAI, the company has struck multiple deals to secure advanced chips and rented computing capacity.
Anthropic recently announced it would partner with Broadcom to source chips based on Google’s tensor processing units, which compete with Amazon’s Trainium chips. The collaboration is expected to provide access to around 3.5 gigawatts of computing power.
In October, Anthropic also confirmed plans to procure up to one million specialised AI chips from a unit of Alphabet Inc., in a deal valued at tens of billions of dollars.
In Monday’s announcement, Amazon said it would supply Anthropic with both general-purpose computing chips and AI accelerators, enabling it to scale up to roughly 5 gigawatts of computing power.
Although Anthropic has enjoyed strong momentum this year with popular offerings such as its Claude Code AI tool, it is also embroiled in a dispute with the United States government over AI safeguards – an issue that has led to legal action by the company, which it says could impact its business.
Amazon said it remains a minority investor and does not hold a seat on Anthropic’s board or trust. The company added that any future investments will be linked to specific commercial milestones.
