Anthropic’s amended IPO filing reports $900.9 billion in purchase and lease obligations, mostly for computing, showing the scale of capacity the AI company has secured before demand is clear.
The Nov. 10 amendment to Anthropic’s Form S-1 says $70.7 billion is due in the 12 months after Sept. 30, 2026. It projects $451.6 billion will be incurred before Dec. 31, 2030, with substantially all of the remaining commitments expected from 2031 through 2045. Most of the total relates to computing resources and supporting infrastructure.
An earlier filing put comparable commitments at $895.4 billion. EconoTimes previously covered Anthropic’s amended IPO filing. The amended figures lay out obligations spread across years, rather than a single near-term payment.
At the December 2025 DealBook Summit, Anthropic CEO Dario Amodei said the company has to arrange computing capacity years before it knows how much revenue that capacity will produce. He described demand as difficult to forecast while capacity decisions must be made in advance.
Amodei said a capacity shortfall could send customers to competitors, while excessive commitments could leave Anthropic without enough revenue to cover them. He said the company plans around a lower-growth scenario near the 10th percentile to preserve its ability to meet obligations if demand falls short.
The filing ties Anthropic’s ability to meet its commitments to growth in its customer base and revenue. Some agreements may require payment even when capacity goes unused, leaving the company exposed if demand does not match the capacity it has secured.
