Is Anthropic Profitable? Annual Revenue, Q3 2026 Losses and Cash Burn Explained

Not on a net basis yet. As of October 29, 2026, Anthropic's S-1 shows an $80.7 billion net loss for H1 2026, but $72.4 billion of that was a non-cash revaluation of convertible notes. Operationally it is close to break-even: a $693 million H1 operating loss, and a $974 million Q2 operating profit, its first profitable quarter in the filing.

Key Takeaways

• Anthropic is not profitable on a GAAP basis. Its S-1, filed October 26, 2026, shows a net loss of $42.0 billion for 2025 and $80.7 billion for the first half of 2026, and Amendment No. 1, filed November 2, 2026, adds a third-quarter net loss of $23.3 billion.
• Almost all of that loss is an accounting charge. In the first half of 2026, $72.4 billion came from marking up convertible notes, mostly Amazon's, as Anthropic's valuation rose, and in the third quarter fair-value changes on the same instruments accounted for about $21.94 billion of the $23.3 billion net loss.
• At the operating line, the second quarter of 2026 brought Anthropic's first GAAP operating profit, $974 million, and the third quarter swung back to a $567 million operating loss, so the nine-month operating loss was $1.26 billion: $693 million in the first half plus $567 million in the third quarter.
• On the company's own non-GAAP measure, Anthropic earned adjusted operating income of $1.6 billion in the first half of 2026, a 10% adjusted operating margin, after a $4.85 billion adjusted loss in 2025, and about $2.46 billion in the third quarter alone, a margin of about 15%, down from about 19% in the second quarter.
• Revenue in the filing was $41 million in 2023, $386 million in 2024 and $4.585 billion in 2025, all audited, and $33.24 billion in the nine months to September 30, 2026, including $16.96 billion in the third quarter, both unaudited interim figures.
• Cash and short-term investments stood at $131.7 billion at June 30, 2026, against $141.1 billion of capital raised since founding, and at $131.8 billion at September 30, 2026.

Is Anthropic Profitable? Two Answers From One Filing

Is Anthropic profitable? Not under GAAP: it earned its first operating profit, $974 million, in the second quarter of 2026, then swung back to a $567 million operating loss in the third quarter, according to its amended S-1 filed November 2, 2026.

The net answer is no: the net loss was $80.7 billion for the first half of 2026 and $23.3 billion for the third quarter, after a net loss of $42.0 billion for all of 2025.

The operating answer is mixed: the operating loss for the half was $693 million, down from $2.14 billion in the first half of 2025, the second quarter alone produced $974 million of operating income, and the third quarter's $567 million operating loss brought the nine-month operating loss to $1.26 billion.

The gap between the two answers is a single line below the operating result, the fair-value change on convertible notes, which is explained below.

The original filing covered the period through June 30, 2026, and Amendment No. 1 added the third quarter, which is broken down in Anthropic's Q3 2026 results.

Part of the third-quarter swing was a non-cash charge of about $2.0 billion for matching employee share donations, and on Anthropic's own adjusted measure, which excludes stock-based compensation and other items, adjusted operating income was about $2.46 billion for the quarter.

What Is Anthropic's Annual Revenue? $33.24 Billion in Nine Months

Anthropic's annual revenue was $4.59 billion in 2025, up from $386 million in 2024 and $41 million in 2023, and the latest filed figure for 2026 is $33.24 billion for the nine months to September 30, an interim number rather than a full year.

• H1 2026 versus H1 2025: $16.29 billion against $1.16 billion, a rise of roughly 14 times in one year.
• Full-year 2025: $4.59 billion, which the first half of 2026 exceeded more than three times over.
• Q2 2026 alone: $11.6 billion, which means the second quarter was larger than the first by a wide margin.
• Q3 2026 alone: $16.96 billion, about 47% more than the second quarter, according to Amendment No. 1.
• First nine months of 2026: $33.24 billion, more than seven times the full-year 2025 total.

These are GAAP-recognized revenues for the periods stated, not annualized projections.

Behind them sit more than 1,900 customers that paid over $1 million in the past year and about 250 that paid over $10 million, as of September 30, 2026.

The two largest customers are Amazon and Google, and the S-1 lists this concentration as a risk factor, because the same companies are also Anthropic's largest investors and cloud partners.

ARR vs Reported Revenue: Why the Numbers Don't Match

Anthropic's run-rate revenue has always been larger than its reported revenue, because the two numbers answer different questions.

Reported revenue is the GAAP total recognized across a period, which is what the S-1 shows.

Run-rate revenue, the figure Anthropic cites in funding announcements, annualizes the most recent weeks of usage, and the S-1 describes it as an operating metric rather than revenue.

ARR, or annual recurring revenue, is the term most people apply loosely to that run-rate figure, even though most of Anthropic's revenue is consumption-based rather than subscription-based.

The public run-rate figures rose from about $1 billion at the start of 2025 to over $5 billion in August 2025.

They reached $14 billion in February 2026 at the Series G round.

By the Series H round they were over $47 billion in May 2026, against $4.59 billion of audited revenue for all of 2025.

When revenue grows more than tenfold in a year, the latest month is always far above the average month, so an annualized snapshot runs ahead of the trailing total until growth slows.

ARR is an annualized estimate, while the S-1 discloses actual revenue recognized under accounting rules, and the two cannot be compared directly.

Why Is Anthropic's Net Loss So Large?

The net loss is so large because Anthropic carries its convertible notes at fair value, and a rising valuation raises that liability, with the increase booked as a loss even though no cash leaves the company.

In the first half of 2026 that fair-value change was about $72.4 billion of the $80.7 billion net loss, which is roughly nine-tenths of the total.

Amazon holds $8.0 billion of the notes, bought between 2023 and 2025, as it reports in its 10-Q for the June 2026 quarter, and the same filing carried them at about $97.9 billion on June 30, 2026, which is the other side of Anthropic's charge.

The same mechanism produced most of the $42.0 billion net loss for 2025, which sat on an operating loss of a much smaller size.

The third quarter followed the same pattern: of a $23.3 billion net loss, about $21.94 billion came from fair-value changes on the convertible notes and related instruments, bringing the net loss for the first nine months of 2026 to $104.0 billion, according to Amendment No. 1.

The charge is a book loss, not cash spent: the company's cash position rose over the same period, as the next section shows.

The notes convert into non-voting shares at the IPO, after which the fair-value line disappears from the income statement.

The ownership behind the notes, including Amazon's 12% cap and Google's position, is covered in the guide to Anthropic's valuation.

How a 693 million dollar operating loss became an 80.7 billion dollar net loss in the first half of 2026.

Cash Burn: Is Anthropic Still Burning Cash?

No, Anthropic was not burning cash in the first half of 2026, and three numbers from the S-1 settle it.

• Operating cash flow: positive $3.9 billion for the six months ended June 30, 2026, compared with an outflow of $1.5 billion a year earlier.
• Cash on hand: $131.7 billion of cash and short-term investments at June 30, 2026, after $141.1 billion of capital raised since founding, and $131.8 billion at September 30, 2026, according to Amendment No. 1.
• Future spending pressure: the compute commitments to Amazon, Google, Microsoft, SpaceXAI and Broadcom are the main claim on that cash; Amendment No. 1 puts compute and infrastructure purchase commitments and leases at about $895.4 billion as of September 30, 2026, about $69.8 billion of it due within 12 months.

Anthropic also expanded its revolving credit facility to $15 billion in September 2026, with a maturity date of September 4, 2031, which adds borrowing capacity on top of the cash balance.

The $80.7 billion net loss and the positive $3.9 billion of operating cash flow describe the same six months, and the difference is the non-cash charge.

What to Watch After the IPO

Three items decide whether Anthropic's operating line gets back above zero after the listing: stock-based compensation, compute costs and customer concentration.

• Stock-based compensation: $1.2 billion for 2025 and $2.2 billion for the first half of 2026 alone, a cost that is already inside the operating result and that rises as new grants are priced at higher valuations.
• Compute costs and commitments: at least $110 billion to Amazon through April 2036, at least about $114.5 billion to Google through July 2033, at least $44.9 billion to Microsoft through May 2033, up to $120.5 billion to SpaceXAI through 2029 and about $161.2 billion of equipment leases with Broadcom over five years.
• Customer concentration: Amazon and Google are the two largest customers as well as investors and cloud suppliers, so a change in either relationship moves both revenue and cost.

The S-1 makes no profitability forecast, and the profitability timeline after the IPO comes down to one condition: the operating line, with stock-based compensation inside it, has to stay above zero, while the fair-value charge ends mechanically once the notes convert at the listing.

Amendment No. 1 has already answered that for the third quarter, with a $567 million operating loss, so the reports Anthropic files after a listing that still has no confirmed Anthropic IPO date will show whether the operating line gets back above zero.

Is Anthropic More Profitable Than OpenAI?

That question cannot be answered with filed numbers for both companies, because OpenAI has no public registration statement and no comparable income statement.

Anthropic's filed figures are a $693 million operating loss for the first half of 2026, a $974 million operating profit for the second quarter and a $567 million operating loss for the third quarter.

OpenAI's most recent company statement, from March 31, 2026, gives a monthly revenue figure and a post-money valuation, not an income statement.

The structural comparison between the two IPO candidates is in the guide to the Anthropic vs OpenAI IPO.

How to Spot a Fake Anthropic Revenue Number

Every Anthropic revenue claim should pass three checks: the period, the metric and the source.

A figure without a period is usually a run-rate presented as revenue, and a figure with a period but no filing behind it is an estimate.

A "profitable" claim that mixes the net loss with the operating result is describing two different things, and only the S-1 and its amendments carry SEC-filed numbers.

Anthropic's own run-rate announcements are first-party but unaudited, and figures discussed at private investor meetings are not in the filing at all.

The $16.8 billion third-quarter figure that circulated after Anthropic's October 14 investor event is one example: the number filed in Amendment No. 1 is $16.96 billion.

The S-1 itself, and where to find each of its sections, is covered in the guide to Anthropic's S-1 filing.

What is Anthropic's annual recurring revenue?

Anthropic quotes a run-rate rather than ARR, last announced at over $47 billion in May 2026, which is an annualized estimate and not comparable to the $33.24 billion of revenue recognized in the first nine months of 2026.

Why did Anthropic lose $80 billion?

Because its convertible notes are marked to fair value, and a rising valuation produced a non-cash charge of about $72.4 billion in the first half of 2026; with the third quarter added, the net loss for the first nine months was $104.0 billion.

When will Anthropic be profitable?

The S-1 makes no forecast, but the fair-value charge ends when the notes convert at the IPO, leaving the operating result, which turned positive in the second quarter of 2026 and negative again in the third, as the number that decides it.

Is Anthropic publicly traded?

Not yet; as of November 5, 2026 Anthropic has filed its public S-1 (October 26) and Amendment No. 1 (November 2), and the stock will trade on Nasdaq as ANT only after pricing.

The Bottom Line on Anthropic's Profitability

Anthropic covered its running costs in the second quarter of 2026 but not in the third, generated $3.9 billion of operating cash in the first half, and still reports net losses in the tens of billions because of how its convertible notes are accounted for.

The operating result moved from a loss of $2.14 billion to a loss of $693 million in twelve months, crossed into profit in the June quarter and fell back to a $567 million loss in the September quarter, so the next filings will show which way it goes.
