Key Points
- Amazon invests $5 billion more in Anthropic, taking total stake to $13 billion
- Anthropic commits to spend over $100 billion on AWS over 10 years
- Deal includes up to 5 gigawatts of computing infrastructure for Claude AI
Anthropic, the maker of the Claude AI assistant, has secured an additional $5 billion investment from Amazon while committing to spend over $100 billion on Amazon Web Services (AWS) cloud infrastructure over the next 10 years, the companies announced on Tuesday.
The fresh investment takes Amazon’s total stake in Anthropic to $13 billion. As part of the expanded agreement, Amazon could invest up to an additional $20 billion in future, contingent on Anthropic achieving certain commercial milestones, the companies stated.
The deal marks one of the largest corporate partnerships in the artificial intelligence sector as companies race to secure the computing power needed to train and run advanced AI models.
What the partnership includes
In exchange for Amazon’s investment, Anthropic has pledged to purchase massive computing capacity from AWS. This includes up to 5 gigawatts of new infrastructure, a measure of electrical power roughly equivalent to the output of five large nuclear power plants, dedicated to training and running its Claude AI models.
The agreement features Amazon’s custom AI chips, including the Trainium2 and the upcoming Trainium3 and Trainium4 accelerators. These processors compete directly with Nvidia‘s dominant GPUs, the specialised chips that power most AI systems today.
Anthropic stated that the agreement will bring nearly 1 gigawatt of Trainium2 and Trainium3 capacity online by the end of 2026. Additional Trainium capacity will roll out in the first half of this year. The company will also have priority access to future Amazon silicon technology once it becomes available.
Why Anthropic needs the computing power
Anthropic CEO Dario Amodei, explained the rationale behind the infrastructure expansion. “Our users tell us Claude is increasingly essential to how they work, and we need to build the infrastructure to keep pace with rapidly growing demand,” Amodei said.
Anthropic stated in its official announcement that the partnership would support rapid development of more powerful AI systems, including a project called Mythos, while using Amazon’s cost-efficient custom hardware.

“This partnership significantly strengthens our ability to scale Claude safely and reliably,” the company stated.
Andy Jassy, Amazon’s CEO, said the company’s custom AI silicon offers high performance at significantly lower cost for customers. “Which is why it’s in such hot demand,” Jassy added.
The Anthropic deal is not Amazon’s only major AI investment. In February 2026, Amazon contributed $50 billion as part of OpenAI’s $110 billion funding round. That investment was also tied heavily to cloud infrastructure usage.
Amazon has positioned itself as one of the biggest corporate backers in the AI sector. The company uses large investments and cloud commitments to secure major AI laboratories as long-term AWS customers while gaining exposure to cutting-edge model development.
Anthropic’s funding history
Prior to this latest investment, Amazon had invested $8 billion in Anthropic. The company has also attracted significant funding from major technology firms and wealth funds.
In February 2026, Anthropic raised $30 billion in its Series G funding round. The company’s valuation stood at approximately $350 billion to $380 billion prior to the recent Amazon investment, according to the funding details.
Singapore’s sovereign wealth fund GIC was part of the Series G round alongside Coatue, helping push Anthropic’s post-money valuation to $380 billion.
Salesforce Ventures has been a consistent backer of Anthropic since participating in the Series C round of funding in early 2023. The firm continued its support through every subsequent round, viewing Anthropic’s technology as reliable and safety-focused for enterprise productivity tools.
Zoom Ventures joined as an early strategic investor during the Series C round in May 2023 alongside Salesforce, Google and others. Zoom has maintained its stake as Anthropic scaled, seeing the partnership as a way to enhance its video collaboration platforms with advanced AI features.
