Anthropic's compute commitments are the real IPO question
The $80.7 billion net loss is mostly accounting; the binding problem is $390 billion owed to four suppliers that are also the company's sales channels.

Anthropic's prospectus, filed on October 26, 2026, invites an argument about the wrong number. The $80.7 billion net loss is largely an artifact of how convertible notes, derivatives and SAFEs are marked as the company's price rises; Fortune put $72.4 billion of it in that bucket, and the operating loss was $693 million on $16.3 billion of first-half revenue. Public investors can see through that.
What they cannot see through is the obligation stack. Reporting on the filing describes roughly $110 billion owed to Amazon through April 2036, $120 billion to SpaceX through 2029, $115 billion to Google and $45 billion to Microsoft through 2033. Those four firms are also, in large part, how Anthropic sells: cloud marketplaces supplied close to half of revenue, and the top five customers about 25% over the first nine months of 2026, according to Fortune. Supplier and distributor are the same parties.
That is why Alphabet's and Amazon's negative free cash flow matters more to this deal than any multiple. If either slows construction to defend cash, Anthropic's capacity growth slows too.
The second-quarter ratio of $2.08 of revenue per dollar of compute is the bull case. It is also the only line that has to hold.
Goldman Sachs and Morgan Stanley lead a 22-bank syndicate into a market where the Nasdaq Composite fell 2.9% on October 30 and other issuers have postponed. Price the contracts, not the loss.
