Amazon has agreed to invest up to $25 billion more in Anthropic, the artificial intelligence company behind the Claude chatbot, according to reporting by The New York Times. The Times reports that Amazon plans to commit $5 billion immediately, with an additional $20 billion tied to Anthropic reaching undisclosed milestones.

As part of the expanded partnership, Anthropic committed to spending $100 billion on Amazon computing services over the next decade, the Times reports. CNBC and GeekWire, citing the companies' announcement, report the same headline figures.

Second Major Tranche From Amazon

The new commitment builds on Amazon's prior $8 billion investment in Anthropic, disclosed in November 2024, according to the Times. Taken together, Amazon's disclosed and potential commitments to Anthropic would reach roughly $33 billion if the full $25 billion is deployed.

The Times reports that Anthropic has, over the past year, become one of the largest users of Amazon's latest in-house AI chip, called Trainium. Amazon has designed Trainium as an alternative to the graphics processing units sold by Nvidia, which supplies most of the chips used to train frontier AI models.

According to GeekWire, the structure of the Anthropic agreement mirrors Amazon's recently announced cloud arrangement with OpenAI, in which compute commitments and equity investment are bundled into a single multi-year pact.

Circular Capital Flows Across the AI Stack

The Times describes the Amazon-Anthropic agreement as part of what it calls "circular deal making at the heart of the A.I. surge," in which large cloud providers invest in AI labs that in turn commit to spending the invested capital — and more — on the providers' infrastructure. The Times notes that Amazon, Google, Microsoft and Nvidia have all participated in similar arrangements.

Anthropic committed to spend $100 billion on computing power and other services from Amazon's cloud computing business over the next decade.

Sherwood News reports that the $100 billion compute commitment from Anthropic covers AWS technology over the next ten years, aligning with the Times' figure. Investing.com and TipRanks report the same $5 billion initial tranche and up to $20 billion in follow-on capital tied to performance conditions.

Neither Amazon nor Anthropic has disclosed the specific milestones attached to the additional $20 billion, according to the outlets covering the announcement.

Anthropic's Compute Footprint and Investor Base

Anthropica's deepening financial relationship with Amazon comes alongside continued fundraising and strategic activity at the company. DeepBrief previously reported on Anthropic's appointment of Novartis chief executive Vas Narasimhan to its board, a move the company tied to expanding its enterprise presence in healthcare.

Anthropic also maintains a separate cloud and investment relationship with Google, which has committed multiple billions to the company in prior rounds, according to the Times. The new Amazon agreement does not appear to alter that arrangement based on the disclosures reported Monday.

The Times reports that Nvidia holds a substantial share of the AI chip market, framing Amazon's continued investment in Trainium as part of a broader effort by cloud providers to reduce dependence on Nvidia hardware. CNBC reports that Anthropic's ongoing use of Trainium gives Amazon a reference customer for the chip at frontier-model scale.

Sustained Spending Despite Investor Scrutiny

The Times notes that the largest technology companies are continuing to commit capital to AI infrastructure at levels that have drawn scrutiny from some investors concerned about the durability of returns. Spending on AI data centers, chips and model training has reached record levels over the past several years, according to the Times.

Amazon has not issued updated financial guidance tied to the Anthropic commitment as of publication, according to CNBC. The company's capital expenditure plans for the year, disclosed in its most recent earnings call, already reflected elevated AI-related infrastructure spending, CNBC reports.

In the broader AI financing landscape, DeepBrief has tracked related capital moves including Cerebras's second IPO prospectus filing, which disclosed $510 million in 2025 revenue, as AI infrastructure providers seek public-market capital alongside the private deals linking hyperscalers to model developers.

Anthropic has not publicly disclosed a revised post-money valuation tied to the new Amazon tranche, and neither company has filed a definitive agreement with securities regulators as of the Times' report.
