Key Notes
- Anthropic’s third-quarter revenue rose approximately 1,127% year over year to $16.956 billion in its amended IPO filing.
- The company reported a $567 million GAAP operating loss and $2.463 billion in adjusted operating income, with a 15% adjusted margin.
- Purchase and lease commitments total approximately $895.4 billion across several years, with $69.8 billion due in the 12 months after September 30, 2026.
Anthropic disclosed third-quarter revenue of $16.956 billion in an amended IPO prospectus filed Monday, up approximately 1,127% from a year earlier. The Claude developer also reported a $567 million operating loss and $2.463 billion in adjusted operating income as prospective ANT investors received a fuller view of its finances.
The November 2 SEC filing adds results for the three months ended September 30 to the company’s proposed Nasdaq listing. Revenue rose about 47% from the second quarter, while compute and infrastructure costs increased faster and the adjusted operating margin narrowed.
The amendment also puts aggregate purchase and lease commitments at approximately $895.4 billion, substantially all related to computing and infrastructure. That is a multiyear commitment total, with spending extending into 2045, rather than a single-year expense or an amount immediately payable.
Quarterly Revenue Reaches $17 Billion
Third-quarter revenue compares with $1.382 billion in the same period of 2025 and $11.555 billion in the second quarter of 2026. Calculated from the filing, the annual increase is 1,126.9% and sequential growth is 46.7%.
Revenue for the first nine months reached $33.242 billion, against $2.545 billion a year earlier. Those figures represent sales recognized during the reported periods, rather than annualized revenue extrapolated from a recent month or customer-spending snapshot.
The new statements give public-market investors a filed set of third-quarter numbers to assess alongside the earlier first-half disclosures. As we previously explained, the appeal of ANT shares will depend on the offering price and the costs and shareholder rights attached to that growth.
Adjusted Profit Differs From GAAP Operating Results
Anthropic reported $17.523 billion of operating expenses, exceeding quarterly revenue by $567 million. That produced a GAAP operating margin of approximately negative 3%, compared with positive 8% in the second quarter.
The company’s adjusted operating income was $2.463 billion, or a reported 15% margin. Its reconciliation adds back $1.070 billion of stock-based compensation and $1.960 billion of non-cash charitable contributions. The latter relates to its donation-matching program and is linked to employee equity awards.
Adjusted operating income increased from $2.235 billion in the second quarter, but the adjusted margin declined from 19%. The business therefore generated a larger adjusted operating profit in dollars while retaining less of each revenue dollar on that measure.
The quarter’s GAAP net loss was much larger, at $23.291 billion. It included a $21.936 billion fair-value loss on convertible notes, derivative liabilities and SAFEs, primarily driven by changes in the value of outstanding convertible notes as Anthropic’s enterprise valuation increased.
Those financing revaluations are distinct from the operating expenses of delivering and developing Claude. As we previously reported, a large non-cash charge can affect reported earnings without representing an equivalent current cash outflow; the associated financing and dilution still matter to shareholders.
Computing Costs Grow Faster Than Sales
Compute and infrastructure expense reached $9.863 billion for the quarter, up from $5.558 billion in the preceding three months. That is an increase of approximately 77%, compared with revenue growth of about 47%.
The expense represented 58% of quarterly revenue in the filing’s rounded presentation, versus 48% in the second quarter. This is an operating-expense category, not a conventional reported gross margin: it covers computing and infrastructure used across the company’s activities.
The comparison adds an important qualification to the growth story. Sales are expanding rapidly, but the resources required to build models and serve customers are also increasing. Future profitability depends on the relationship between those costs, pricing and customer usage.
For the first nine months, Anthropic reported $6.569 billion of cash provided by operating activities. That year-to-date cash-flow figure should be assessed separately from quarterly adjusted operating income and the GAAP net loss. They measure different aspects of the business and cover different periods.
Commitments Reach $895 Billion Across Several Years
The approximately $895.4 billion total includes purchase commitments, leases, short-term and subsequent commitments, and leases that had not yet commenced. It incorporates arrangements entered into as of and after September 30.
Anthropic expects approximately $447.5 billion to be incurred before December 31, 2030, with substantially all the remainder between 2031 and 2045. Approximately $69.8 billion is due in the 12 months following September 30, 2026.
Some obligations have conditions attached. Approximately $213.8 billion relates to arrangements with exercisable termination rights or conditions before commencement, including counterparties obtaining financing, facilities or regulatory approvals. The aggregate therefore should not be described as an entirely unconditional debt balance.
The financing challenge is the duration mismatch. Anthropic says much of its consumption-based revenue lacks long-term customer commitments, while computing obligations generally extend over multiple years. Continued customer spending and access to capital will determine its ability to support those commitments.
ANT Remains a Proposed Nasdaq Listing
Anthropic has applied to list Class A shares on the Nasdaq Global Select Market under ANT. The amended prospectus still leaves the offer price range and number of shares blank, so the financial update does not establish a final IPO valuation, proceeds total or public trading price.
The new filing advances the disclosure process without completing the offering. Its immediate significance is the clearer comparison investors can now make: extraordinary revenue growth, positive adjusted operating income, a GAAP operating loss and a substantial long-term infrastructure bill.
