Anthropic has committed to roughly $517 billion in compute capacity agreements since October last year, an analysis by The Information found, and Data Center Dynamics reported the tally on September 4. The total spans 14.8 gigawatts of leased and cloud capacity, with Google and AWS together accounting for 11 gigawatts of it. None of that figure is money already spent: it is the contracted value of agreements Anthropic will draw on over the next several years.
The deals split roughly into two categories. On the data center side, Anthropic has locked in leases with providers including Riot Platforms in Texas, along with over a dozen further letters of intent signed with US developers, and a $200 billion agreement with Google covering TPU capacity it could run itself. Late August added a $45 billion capacity agreement with Nscale, one of the largest single leases in the mix.
On the cloud side, Anthropic has struck agreements with Amazon Web Services (including a large cluster of AWS’s custom Trainium chips), CoreWeave, a $50 billion partnership with Fluidstack, and Akamai, alongside smaller commitments to Lambda, Microsoft, AMD, Google Cloud, Volta Infra, and SpaceX’s xAI. Spreading commitments across that many providers reduces Anthropic’s exposure to any single supplier’s build schedule. It also means the company is now on the hook for capacity that lands in stages over several years, whether or not demand arrives on the same timeline.
Anthropic previously told investors it expected to spend around $180 billion renting servers through 2029. The new total is nearly triple that figure, and The Information’s analysis notes Anthropic could have signed additional agreements it has not made public. Data Center Dynamics said it had contacted Anthropic for comment and had not received a response as of publication.
Anthropic confidentially filed for an IPO with the SEC in June, and this compute tally lands the same week AI Insiders reported that the company’s IPO timetable has reportedly slipped toward mid-October. A $517 billion capacity book is exactly the kind of commitment underwriters and prospective public shareholders will want explained, since it is a claim against future cash flow rather than evidence that the revenue to cover it already exists.
The more useful number here is not $517 billion. It is how much of that 14.8 gigawatts needs to be running paid workloads before the lease payments actually start, given that a signed contract is a fixed obligation while the revenue behind it is still a forecast. Anthropic’s eventual IPO prospectus, whenever it lands, will be the first place outside investors can check that math against the company’s own figures rather than a compiled estimate.
Data Center Dynamics reported on September 4, citing an analysis by The Information that compiled Anthropic’s public compute announcements.
