Well, this is the Platonic ideal of a circular AI deal.

In a joint press release, Microsoft, Nvidia, and Anthropic (maker of the Claude genAI) announced a strategic partnership that includes a slew of 10- and 11-digit investment plans:

• Anthropic will purchase $30 billion of computing capacity from Microsoft’s Azure.

• Anthropic’s commitment includes up to 1 gigawatt in computing capacity that will be served through Nvidia’s Grace Blackwell and (yet to be released) Vera Rubin systems.

• Microsoft is investing up to $5 billion in Anthropic.

• Nvidia is investing up to $10 billion in Anthropic.

That’s revenues for Microsoft and Nvidia, and two high-profile investors for Anthropic.

Bank of America analysts have argued that these circular-seeming deals are a way for leaders in the space to beef up their potential addressable market that “could multiply future benefits.”

Anthropic announced its foray into data centers last week with plans for $50 billion in custom-built locations in partnership with Fluidstack. The company is targeting $70 billion in revenues by 2028, which would help it support this capex binge.

Despite the massive numbers being tossed around here, Anthropic said that Amazon’s AWS would remain its primary cloud provider, per Bloomberg.
