Amazon is exploring a fresh multibillion-dollar investment in AI startup Anthropic to deepen their strategic alliance, aiming to secure a competitive edge in the global race to commercialize artificial intelligence, according to a detailed report by the Financial Times.
The Seattle-based e-commerce and cloud computing giant has already invested around $8 billion in the San Francisco-based AI model builder. Now, insiders reveal that Amazon is in talks to significantly increase this figure. The expanded investment would not only maintain Amazon as one of Anthropic’s largest shareholders but also position it ahead of Google, which has invested over $3 billion, and counterbalance the powerful Microsoft-OpenAI partnership.
Interviews with more than a dozen executives, board members, and investors from both companies underscore how vital this collaboration has become to their futures. The partnership extends beyond capital infusion to joint efforts on one of the world’s largest data center projects, known as “Project Rainier,” located in Indiana. These data centers, powered by Amazon’s custom Trainium2 chips, are designed to support Anthropic’s heavy computing demands and could ultimately double in scale.
Dan Grossman, Amazon’s vice-president of worldwide corporate development, emphasized the alignment of goals: “We quickly realised that we had many shared goals that were fundamentally critical. The size of the [existing investment] represents our ambition.”
While Amazon develops its own foundation AI models, its relationship with Anthropic remains closer than that with Google, which focuses on its Gemini AI models. According to regulatory filings cited by the Financial Times, Amazon’s investment is valued at about $13.8 billion, structured mainly through convertible notes with limited equity converted so far.
Anthropic, founded in 2021 by former OpenAI staff concerned with AI safety, operates as a public benefit corporation with a $61.5 billion valuation as of March 2025. Its AI models, branded under “Claude,” are embedded in Amazon products like Alexa+ and Prime Video. Notably, Amazon’s sales teams actively promote Anthropic’s models to their cloud customers, in contrast to Google’s preference for its own Gemini models, a source told the Financial Times.
Despite the strong partnership, Amazon’s own push to train internal AI models presents a challenge for Anthropic, which depends heavily on Amazon for cloud infrastructure and corporate customer access. However, Amazon executives express confidence that their collaboration is more robust than Microsoft’s relationship with OpenAI, thanks to Anthropic’s structure allowing for equity investment rather than a complex profit-sharing model.
As the AI arms race intensifies, Amazon’s possible expanded investment signals its determination to remain a dominant player in artificial intelligence, leveraging its cloud infrastructure and deepening ties with innovative AI startups like Anthropic.
