Anthropic is betting big on Amazon’s infrastructure. The AI company behind Claude has announced a massive expansion of its partnership with Amazon Web Services, committing more than $100 billion over the next decade to secure up to 5 gigawatts of compute capacity.
The deal comes as Anthropic struggles to keep up with surging demand for its Claude AI assistant. The company’s run-rate revenue has jumped to over $30 billion in 2026, up from around $9 billion at the end of 2025. This rapid growth has strained infrastructure and caused reliability issues for users across all tiers.
Infrastructure investment reaches new heights
The partnership expansion covers three main areas. First, Anthropic is making its largest infrastructure commitment yet – over $100 billion across ten years. This secures access to Amazon’s custom AI chips, from current Trainium2 processors through future Trainium4 chips.
The timeline is aggressive:
- Significant Trainium2 capacity comes online in Q2 2026
- Nearly 1 gigawatt total of Trainium2 and Trainium3 capacity by end of 2026
- Expanded inference capacity in Asia and Europe
“Our custom AI silicon offers high performance at significantly lower cost for customers, which is why it’s in such hot demand,” said Andy Jassy, Amazon’s CEO. The commitment reflects how crucial custom silicon has become for training large language models cost-effectively.
Claude platform gets AWS integration
Anthropic is also bringing its full Claude Platform directly into AWS. This means organizations can access Claude through their existing AWS accounts with the same billing and controls they already use. No additional contracts or credentials needed.
This integration matters because it removes friction for enterprise customers who want advanced Claude features but need to meet strict governance requirements. The platform is currently in private beta, with access available through AWS account teams.
Amazon doubles down with $25 billion total investment
Amazon is backing the partnership with serious money. The company is investing an additional $5 billion in Anthropic immediately, with up to $20 billion more planned for the future. Combined with Amazon’s previous $8 billion investment, this brings the total potential investment to $33 billion.
For context, this makes Amazon one of the largest investors in AI infrastructure globally. The move signals how important Amazon views its position in the AI cloud market, especially as it competes with Microsoft’s OpenAI partnership and Google’s own AI efforts.
Growing pains drive infrastructure push
The expanded partnership comes at a critical time for Anthropic. The company has seen explosive growth in both enterprise and consumer usage across its free, Pro, and Max tiers. Over 100,000 customers now run Claude on Amazon Bedrock.
But success has brought challenges. Anthropic admits that unprecedented consumer growth has impacted reliability and performance, especially during peak hours. Users across all tiers have experienced issues as the company’s infrastructure struggled to keep pace.
“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,” said Dario Amodei, Anthropic’s CEO and co-founder.
The new capacity should provide immediate relief, with meaningful compute additions expected within three months. This infrastructure build-out is essential for Anthropic to maintain its position as one of the few companies offering frontier AI models across all three major cloud platforms – AWS, Google Cloud, and Microsoft Azure.
