Anthropic Files Confidential IPO as It Pays SpaceX $15B a Year

Anthropic filed a confidential IPO prospectus the same day SpaceX began its roadshow and pays SpaceX $1.25 billion a month for GPU compute, about $15 billion a year.

Anthropic filed a confidential IPO prospectus with the SEC on the same day SpaceX opened its public offering roadshow. The filing discloses a contract under which Anthropic pays SpaceX $1.25 billion a month for GPU compute.

The agreement supplies 325,000 Nvidia GPUs at SpaceX’s Colossus and Colossus II facilities in Memphis. SpaceX’s amended IPO filing states the contract runs through May 2029 and presents up to roughly $45 billion in potential future payments.

The contract includes a termination clause: after an initial three-month period, either party may end the agreement with 90 days’ notice. SpaceX’s filing presents the Anthropic payments as a material revenue source for the company.

SpaceX is targeting a $75 billion valuation and plans a June 12 Nasdaq debut under the ticker SPCX. Anthropic’s confidential filing follows and is reported to be targeting a valuation near $965 billion.

Goldman Sachs is the lead bank on SpaceX’s offering. Morgan Stanley is managing a direct share program that reserves 5% of IPO stock for insiders selected at executive discretion and includes no lockup restrictions.

Anthropic competes in the AI market with the Claude model while xAI offers Grok. Anthropic is also building its own compute infrastructure, which the company says could reduce future third-party compute purchases.

Elon Musk wrote on X in February: “Is there a more hypocritical company than Anthropic?” In May he wrote: “Everyone I met was highly competent and cared a great deal about doing the right thing. No one set off my evil detector.” The shift in tone occurred over roughly 90 days, the same notice period in the compute contract.

The filings show SpaceX listing Anthropic payments as a substantial revenue stream while the contract gives either side the ability to exit with roughly 90 days’ notice. Anthropic’s IPO prospectus filings are expected to provide more detail on its finances and on how much it plans to rely on third-party compute versus its own infrastructure.
