Amazon has agreed to invest up to $25 billion in Anthropic, on top of the $8 billion that it's poured into the artificial intelligence startup in recent years, as part of an expanded agreement to build out AI infrastructure.
In the announcement on Monday, Anthropic said it's committed to spend more than $100 billion on Amazon Web Services technologies over the next 10 years, including current and future generations of Trainium, Amazon's custom AI chips. Anthropic said it's secured up to 5 gigawatts of capacity for training and deploying its Claude AI models.
"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," Amazon CEO Andy Jassy said in a statement.
Amazon's investment includes $5 billion into Anthropic now, with up to $20 billion in the future tied to "certain commercial milestones," according to a release. The initial investment is at Anthropic's latest valuation of $380 billion.
Anthropic said in the release that it will bring nearly 1 gigawatt total of Trainium2 and Trainium3 capacity online by the end of the year.
With all of the major hyperscalers competing to build out AI capacity as quickly as possible, Amazon said in February that it expects to shell out roughly $200 billion this year on capital expenditures, mostly on AI infrastructure.
Amazon's investment lands just two months after the e-commerce giant agreed to invest up to $50 billion in OpenAI, Anthropic's chief rival. The two AI companies have been racing to convince investors of their strengthening positions ahead of potential IPOs that could land as soon as this year. OpenAI executives have been criticizing Anthropic in recent months for making a "strategic misstep to not acquire enough compute."
Anthropic said on Monday that enterprise and developer demand for Claude, as well as a "sharp rise" in consumer usage, has led to "inevitable strain" on its infrastructure that has impacted its reliability and performance. The company said its new agreement with Amazon will quickly expand its available capacity.
"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," Anthropic CEO Dario Amodei said in a statement. "Our collaboration with Amazon will allow us to continue advancing AI research while delivering Claude to our customers, including the more than 100,000 building on AWS."
Anthropic was founded in 2021 by a group of researchers and executives who defected from OpenAI. The company is best known for its family of Claude AI models and it's found early success selling to enterprises. Annualized revenue has topped $30 billion.
Anthropic named AWS its primary cloud provider in 2023 and its primary training partner in 2024, but the company has also inked deals with competing providers, including Microsoft and Google.
In November, Microsoft agreed to invest up to $5 billion into Anthropic, and Anthropic said it committed to purchasing $30 billion of Azure compute capacity. Earlier this month, Anthropic expanded its partnerships with Google and Broadcom for "multiple gigawatts" of capacity.
