Amazon closes $2.75B Anthropic deal in its biggest venture bet ever

Amazon just cut the largest outside check in its thirty-year history to make sure it doesn't get left behind in the generative AI arms race.

The tech giant confirmed it has poured another $2.75 billion into Anthropic, completing the $4 billion investment pledge it first outlined back in September. The fresh cash injection keeps Anthropic at its previous valuation of $18.4 billion, with Amazon maintaining a minority stake and no board seat.

Buying a seat at the frontier table

Basically, the deal is a massive compute marriage. Anthropic gets the gargantuan cash pile needed to train cutting-edge models, and Amazon Web Services locks in a premier AI showpiece to challenge OpenAI.

Under the terms, Anthropic commits to AWS as its primary cloud provider. Even more importantly for Amazon's hardware ambitions, the startup will use Amazon's custom-designed chips to train, build, and deploy its future models, giving AWS a crucial testing ground as it tries to build alternatives to Nvidia silicon.

The timing is no accident. Anthropic recently unveiled Claude 3, boasting that its flagship model beat OpenAI's GPT-4 and Google's Gemini Ultra across major benchmarks. For AWS, having native access to the team that built Claude is the clearest counterpunch to Microsoft's tight partnership with OpenAI.

Anthropic has become a magnet for Big Tech capital, raking in about $7.3 billion across five funding rounds in the past year alone. Alongside Amazon, Google has committed up to $2 billion, while Salesforce holds a stake. Just last week, bankrupt crypto exchange FTX also agreed to offload the majority of its Anthropic holding.

The cloud revenue merry-go-round

Before Anthropic, Amazon's top venture bet was an investment of over $1.3 billion in electric vehicle maker Rivian. This new deal dwarfs that record, reflecting a broader pivot across the tech industry.

With antitrust regulators blocking outright acquisitions, tech giants are funneling cash through minority stakes. PitchBook data shows AI investments from the Magnificent Seven jumped from $4.4 billion in 2022 to $24.6 billion last year, while outright M&A deals cratered from 40 to just 13.

Yet the circular flow of funds is raising eyebrows. Critics like venture capitalist Bill Gurley have pointed out that Big Tech firms are effectively subsidizing their own cloud revenues by giving startups cash that flows right back to their servers. The U.S. Federal Trade Commission is already conducting a formal inquiry into these mega-cloud tie-ups, though Amazon maintains the structure is entirely legitimate venture investing.

Why it matters

For enterprise builders and developers, this brings immediate stability and competitive pricing. If you rely on AWS, you now have first-class access to Claude 3 without needing an Azure migration, backed by an AI startup whose war chest is practically bottomless for the near term.

For the AI ecosystem, the battle lines are now completely drawn. Microsoft has pumped an estimated $13 billion into OpenAI, while Amazon and Google are splitting custody of Anthropic. Amazon had to write this check; falling behind on foundation models would have threatened AWS's status as the default engine of the internet.

We think Amazon played this smartly by mandating the use of its in-house silicon, solving both a software shortfall and a hardware distribution problem in one fell swoop. The real vulnerability, however, is regulatory. If the FTC decides that cloud credits and circular revenues artificially prop up quarterly metrics, this entire playbook of proxy wars through minority funding rounds could grind to an abrupt halt.
