Amazon.com Inc. said it will invest another $25 billion in Anthropic, expanding a thriving partnership in which Anthropic has committed to spending more than $100 billion on AWS over the next decade.
The deal, announced Monday, includes an immediate $5 billion cash infusion, with the remaining $20 billion contingent upon meeting specific commercial milestones. The latest investment round values Anthropic at $380 billion, reflecting intense investor appetite for generative artificial intelligence (AI) leaders.
Amazon has already poured $8 billion into the startup in recent years.
Central to the agreement is Anthropic's commitment to Amazon's custom silicon. The startup will utilize current and future generations of Trainium chips to train and deploy its large language models. To facilitate this, Anthropic has secured up to 5 gigawatts of power capacity -- roughly enough to power millions of homes -- specifically for its AI operations.
The move addresses a sharp rise in consumer and enterprise demand that has recently strained Anthropic's infrastructure.
"Our users tell us Claude is increasingly essential to how they work, and we need to build the infrastructure to keep pace," said Anthropic CEO Dario Amodei.
By the end of this year, the company expects to bring nearly 1 gigawatt of Trainium2 and Trainium3 capacity online to bolster reliability and performance.
Amazon's aggressive maneuver comes just two months after it pledged $50 billion to OpenAI, Anthropic's primary rival. In backing both horses, Amazon is positioning itself as the indispensable backbone of the AI industry.
"Amazon is trying to invest in all majored AI companies to make sure they can have a say in what runs on their platforms," tech analyst Jack Gold said in an email. "Customers want choice and AWS needs to offer options. If you own a piece of the company, it's much easier to get them to give you what you need."
Amazon CEO Andy Jassy noted that the decade-long commitment to Trainium validates the company's progress in custom silicon, a key differentiator against rivals like Microsoft Corp. and Google.
Amazon expects to spend approximately $200 billion this year alone on capital expenditures, the vast majority dedicated to AI infrastructure. Meanwhile, Anthropic, which was founded in 2021 by former OpenAI executives, is seeing its own meteoric rise, with annualized revenue now topping $30 billion.
While AWS remains Anthropic's primary cloud partner, the startup continues to diversify its dependencies. It recently secured a $5 billion investment from Microsoft and expanded its partnerships with Google and Broadcom Inc.
However, this latest $25 billion pact ensures that for the foreseeable future, the path to the most advanced AI models runs directly through Amazon's data centers.
