Anthropic put a specific number on its compute and infrastructure commitments for the first time in Amendment No. 1 to its Form S-1 (S-1/A), filed with the U.S. Securities and Exchange Commission on November 2, 2026: about $895.4 billion, substantially all of it related to compute and infrastructure. This is not money already spent. It is a payment schedule stretching almost twenty years, with about $69.8 billion due in the 12 months after September 30, 2026. The faster revenue grows, the larger the compute bill locked in ahead of time.
The $895.4 billion total covers more than one contract table
The total counts purchase commitments and lease agreements entered into as of and subsequent to September 30, 2026, including short-term commitments and leases that have not yet commenced. The contractual-obligations table as of September 30 alone totals only about $320.0 billion. The gap comes from counting arrangements signed after September 30, and those not yet commenced, in the larger total.
On timing, about $447.5 billion is expected to be incurred before December 31, 2030, with substantially all of the rest falling between 2031 and 2045. The roughly $69.8 billion due in the next 12 months comes first. The filing also notes that a significant portion follows the Anthropic Direct model: leasing chips and hosting them in dedicated facilities, rather than only buying services from cloud providers.
Not every dollar is already locked in
About $213.8 billion is subject to exercisable termination rights or conditions that must be met before commencement, such as a counterparty securing financing, facilities, or regulatory approvals. If those conditions are not met, the arrangement may be terminated. About a quarter of the total, in other words, depends on counterparties delivering the supporting conditions.
But most of the flexibility sits further out. Of the roughly $69.8 billion due in the next 12 months, only about $4.3 billion carries such conditions or rights, so the near-term payments are largely firm. In the other direction, arrangements without a fixed amount are excluded from the total, and Anthropic estimates they will cost another $150 billion to $175 billion once capacity is delivered. The total is neither a ceiling nor a final bill.
Read the bill against revenue, cash, and the rest of the same filing
Third-quarter revenue was $16.956 billion, up about twelvefold year on year and about 47% quarter on quarter, but the company swung to a $567 million operating loss in the third quarter. As of September 30, Anthropic held about $131.8 billion in cash and short-term investments, and the $69.8 billion due in the next 12 months is about half of that total. The filing also warns that a failure by an infrastructure partner to secure financing for equipment could affect delivery of committed compute.
The same amendment also added a warning about AI-accelerated research, saying future models could soon reach the company's internal threshold for dramatically accelerated AI-driven progress. The offering price, share count, and offering size remain blank in the amendment, and no listing date has been set. What matters next is how much of the $213.8 billion converts into firm compute delivery, and whether revenue growth keeps pace with the payment schedule.
