Anthropic, a leading artificial intelligence research company, has significantly expanded its partnership with Amazon, committing to spend over $100 billion on Amazon Web Services (AWS) technologies over the next decade. This landmark agreement secures up to 5 gigawatts (GW) of compute capacity for training and deploying its Claude AI models, addressing the rapidly growing demand for its services. Amazon, in turn, is investing an additional $5 billion in Anthropic, with potential for up to $20 billion more in the future, building on its previous $8 billion investment.
The collaboration will see Anthropic utilize current and future generations of Amazon's custom silicon, including Trainium2, Trainium3, Trainium4, and Graviton chips. Significant Trainium2 capacity is expected to come online in the second quarter of this year, with nearly 1 GW of combined Trainium2 and Trainium3 capacity anticipated by the end of 2026. This infrastructure expansion is crucial for Anthropic, which reported its annualized revenue has surged to $30 billion, up from approximately $9 billion at the end of 2025.
Dario Amodei, CEO and co-founder of Anthropic, emphasized the necessity of this expansion, stating, "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." The partnership also includes an expansion of inference capacity in Asia and Europe to better serve Claude's growing international customer base. Over 100,000 customers currently run Claude models on AWS, making it one of the most popular AI families on Amazon Bedrock.
Andy Jassy, CEO of Amazon, highlighted the performance and cost benefits of their custom AI silicon. "Anthropic's commitment to run its large language models on AWS Trainium for the next decade reflects the progress we've made together on custom silicon, as we continue delivering the technology and infrastructure our customers need to build with generative AI," Jassy commented. The full Claude Platform will also be available directly within AWS, offering customers seamless access through their existing accounts.
This deepened alliance underscores the intense "AI compute wars" and the strategic importance of securing vast computational resources for frontier AI development. Anthropic has also forged partnerships with other tech giants like Google and Microsoft for compute capacity, showcasing a diversified strategy to meet its escalating infrastructure needs. The deal solidifies AWS as Anthropic's primary training and cloud provider for mission-critical workloads, further cementing Amazon's position in the competitive AI landscape.
