Anthropic files its IPO prospectus publicly
The S-1 document blocked access (403), so this edition did not read the filing and relies on two press reports. Outlets give different totals for compute commitments depending on what they include; the $417 billion minimum and the $125 to $150 billion estimate are separate figures, and neither is cash already paid. The net loss is mostly non-cash and is not cash burn. No offer price, share count or trading date has been set, and the filing can still be amended.
What was claimed?
SEC records show Anthropic, PBC filed a public S-1 registration statement on October 26, 2026, after confidential draft submissions since June. DataCenterDynamics and Fortune report that the filing shows $16.3 billion of revenue in the first half of 2026 and a net loss of $80.7 billion, of which $72.4 billion was a one-off accounting charge. The filing reportedly gives about $417 billion of future minimum payments under lease and commercial agreements for compute and infrastructure, and an estimated $125 billion to $150 billion more for capacity to be delivered between 2028 and 2031 whose terms are not final.
What does the evidence support?
Reported claim, not independently established
This is the first public filing behind figures that until now came from reports of draft documents. Fortune reports second-quarter revenue of $11.6 billion against $5.6 billion of compute costs, compute access of up to $120.5 billion from SpaceX through 2029, and a plan for Anthropic Direct, in which partners build and run data centres that Anthropic leases.
