Anthropic's Amended S-1 Shows $16.96B Q3 Revenue, a $23.3B Net Loss and $895B in Commitments

Anthropic reported third-quarter 2026 revenue of $16.96 billion, up 1,127% from a year earlier and 47% from the second quarter, alongside a $23.3 billion net loss, according to its amended registration statement filed with the SEC on Nov. 2. The filing also shows about $895.4 billion in purchase and lease commitments and a GAAP operating loss of $567 million, a reversal from a $974 million operating profit in Q2. The company plans to list on Nasdaq under the symbol ANT; no price range has been announced.

Q3 2026 at a glance

Why operating income turned negative

The swing from a $974 million operating profit in Q2 to a $567 million loss came from costs that landed ahead of the revenue they support. The filing points to about $5 billion of short-term compute costs and about $2 billion of noncash charges tied to donation matching. The original filing also said new compute is expensed as it comes online, often before the revenue it supports, so margins can compress in those periods.

Adjusted operating income, a non-GAAP measure that excludes items such as stock-based compensation and noncash charitable contributions, stayed positive at $2.5 billion. Its margin slipped to about 15% from 19%. By our calculation, the GAAP operating margin was about -3.3%, against about +8.4% in Q2.

Where the $23.3 billion loss comes from

The net loss is far larger than the operating loss, which points to noncash items below the operating line. Anthropic marks its convertible notes, derivatives and SAFEs to market, so a higher company valuation raises the expense. Of the nine-month loss of about $104 billion, $94.3 billion is a noncash charge tied to convertible-note valuations. By our calculation, excluding that charge, the nine-month loss would be about $10 billion.

Revenue and customers

Nine-month revenue reached $33.2 billion, compared with $2.5 billion a year earlier. Quarterly revenue has stepped up from $4.73 billion in Q1 2026 to $11.56 billion in Q2 and $16.96 billion in Q3. The filing reports more than 1,900 customers spending at least $1 million and $13.8 billion in remaining performance obligations, contracted revenue not yet recognized.

The $895 billion commitment figure

Purchase and lease commitments total about $895.4 billion, and the figure includes commitments entered into after Sept. 30. These are contractual obligations spread over future years, mostly for compute capacity, not money already spent. For scale, the total is more than 50 times the quarter's revenue, by our calculation. The original October filing described large multi-year compute agreements with several providers, and the new total is well above earlier published estimates, which ranged from roughly $518 billion to $750 billion before this amendment.

IPO status

Anthropic plans to list on Nasdaq under ANT. The share count and price range have not been announced, and the prospectus remains subject to completion. The original filing named 22 underwriters, with Goldman Sachs and Morgan Stanley as representatives. The amended numbers give investors the first full look at a quarter in which revenue growth, heavy compute spending and valuation-driven charges all pushed in different directions.

What to watch

• Pricing and valuation. A range and share count will define how much the market pays for the growth, and a higher valuation would also raise future noncash charges on convertible instruments.
• Margins. Adjusted margin fell to about 15% as compute came online ahead of revenue; the path back up depends on utilization.
• Commitments versus cash. The original filing cited roughly $131.7 billion of cash at June 30; the gap to $895 billion shows how much future funding the plan depends on.
• Market backdrop. A shaky tape could affect timing. See our Research Desk analysis and the week's calendar in our Week Ahead article. Earlier coverage: Anthropic's original IPO draft.
