Anthropic's updated prospectus, filed with the U.S. Securities and Exchange Commission on November 10, contains a set of big numbers.
From May to October this year, it signed and revised multiple computing power agreements with SpaceX.AI, a subsidiary of SpaceX, covering Nvidia GPU computing power. The contract extends until 2029, with a planned spending cap of US$120.5 billion. All computing power is expected to be delivered in December this year, and the monthly cost will be approximately US$3.1 billion by then.
Compare the scale initially announced: $1.25 billion per month, covering approximately 325,000 Nvidia GPUs in two data centers, Colossus and Colossus II. The monthly rent more than doubled in a few months.
Then came word in the market that Anthropic might not renew the lease after mid-2027. Musk responded on X: He would be happy to take back the computing power, but he believes that the actual situation may be the opposite.
This sentence makes sense on both sides. SpaceX has said at the beginning that this contract structure can, on the one hand, monetize some of its computing power to the outside world, and on the other hand, it also leaves room for recycling for its own AI business. The recovered cards can be used by Grok or subleased to other customers.
Musk’s confidence comes from production capacity. SpaceX has deployed about 1.7 gigawatts of computing power as of the end of September, and he expects that to be 2.5 to 3 gigawatts by the end of the year, with about 10 gigawatts added in 2027.
Anthropic is also diversifying risks while signing large orders: buying its own gas generator, looking for new inference chips like Fractile, and moving the model to AMD. With a monthly bill of $3.1 billion, no one wants to bet on just one company.
