Amazon announced on Monday that it will invest up to $25 billion in Anthropic, the AI startup behind the Claude family of models, as part of a landmark agreement in which Anthropic commits to spending more than $100 billion over the next decade on Amazon's cloud technologies. The deal marks a significant deepening of ties between the Seattle-based e-commerce and cloud giant and one of the most prominent players in the artificial intelligence industry.
Under the terms of the agreement, Amazon will immediately invest $5 billion in Anthropic, with an additional $20 billion available in the future subject to commercial milestones being met. This comes on top of the $8 billion Amazon had already committed to the company in previous rounds of investment, bringing its total potential stake to $33 billion. Amazon shares rose around 2.7% in extended trading following the announcement.
A central element of the deal involves Anthropic's use of Amazon's custom silicon chips — Trainium2 and Trainium3 — which are designed specifically for AI training and inference. Anthropic said it expects to bring roughly one gigawatt of computing capacity using these chips online by the end of the year, with an ultimate target of up to five gigawatts. Amazon CEO Andy Jassy described Anthropic's commitment to the chips as reflecting "the progress we've made together on custom silicon," signalling that the deal serves Amazon's strategic goal of expanding the customer base for its proprietary hardware.
For Anthropic, the deal provides the computational firepower needed to compete in an increasingly crowded AI landscape, with the company focusing its near-term model development on coding and design capabilities. For Amazon, which has struggled to generate widespread excitement around its own AI models such as Nova, the partnership offers a way to remain central to the AI boom through infrastructure and investment rather than frontier model development alone. The company anticipates spending around $200 billion in capital expenditures this year, largely directed at AI.
The Anthropic deal follows Amazon's separate announcement earlier this year that it would invest up to $50 billion in OpenAI, the maker of ChatGPT — a move that underscores the scale of resources the world's largest technology companies are deploying to secure positions across the AI ecosystem. Together, these investments reflect a broader pattern in which cloud providers are betting heavily on AI startups, locking in long-term infrastructure commitments in exchange for equity stakes.
