Inside Anthropic's S-1 Filing: Revenue Growth, Net Losses, and the True Cost of AI Compute

 

Anthropic, PBC filed a Form S-1 registration statement publicly with the US Securities and Exchange Commission on October 26, 2026, intending to list on the Nasdaq Global Select Market under the ticker ANT, with the share count and price range both undetermined.

 

The filing shows a net loss of $80.748 billion for the first half of 2026 against revenue of $16.286 billion, a loss close to five times revenue. That ratio looks anomalous until the components separate: the operating loss was only $693 million, while $72.388 billion of the net loss came from changes in the fair value of convertible notes, derivative liabilities and SAFEs, all non-cash. Operating activities generated positive cash flow of $3.929 billion over the same period, against negative $1.513 billion a year earlier.

 

Put differently, the company came close to breakeven at the operating line and was cash-generative during the half, while the enormous net loss mostly records something unrelated to operations: a rising company valuation pushing up the carrying value of early convertible instruments.

 

The risk worth attention sits not in the net loss figure but in the comparison between compute purchase commitments and cash reserves, along with a detail easily missed: the aggregate commitment amounts in the public S-1 are left blank, so the totals widely quoted in media coverage do not come from that table. This article works through the filing line by line.

 

 

 

Of the $80.748 billion net loss, $72.388 billion came from non-cash fair value changes. The filing attributes this to an increase in the fair value of its outstanding convertible promissory notes.

 

The operating loss was only $693 million, narrower than the $2.135 billion a year earlier. Operating income turned positive in the second quarter of 2026 at $974 million, the first positive figure among the six quarters shown.

 

Operating activities generated positive cash flow of $3.929 billion. That compares with negative $1.513 billion a year earlier and negative $2.637 billion for full-year 2025.

 

First-half revenue of $16.286 billion ran fourteen times the $1.163 billion a year earlier. The second quarter alone, at $11.555 billion, exceeded the roughly $5.01 billion total for 2023 through 2025 combined.

 

Compute and infrastructure spending fell from 201% of revenue to 55%. The absolute figure rose from $2.334 billion to $8.945 billion, growing more slowly than revenue.

 

The aggregate purchase commitment figures in the public S-1 are blank. The roughly $637 billion circulating in coverage is a third-party sum of individually disclosed contracts, not a filing-stated total.

 

Customer concentration is disclosed but no single customer exceeds 10%. For the nine months ended September 30, 2026, the top five customers accounted for roughly 25% of revenue.

 

 

The significant change from the earlier confidential submission is that the financial statements moved from media paraphrase to a document that can be checked line by line.

 

Confirmed items include the Nasdaq Global Select Market as the listing venue, ANT as the ticker, Anthropic, PBC as the registrant, and Goldman Sachs and Morgan Stanley as the contacts for the preliminary prospectus. The registration statement has not yet become effective, and the securities may not be sold before it does.

 

Undetermined items include the share count, the price range, the total raise, the split between company and selling stockholder shares, and the effective date.

 

Earlier coverage on this site worked from Reuters reporting on the confidential filing to map the compute buildout commitments and the supplier landscape, citing full-year 2025 figures of roughly $4.585 billion in revenue, a roughly $8.060 billion operating loss and a roughly $41.965 billion net loss. The public filing confirms those magnitudes and adds the first half of 2026, where the trajectory looks considerably different from full-year 2025.

 

 

 

This table contains the whole puzzle the article sets out to explain. Revenue grew from $41 million in 2023 to $16.286 billion in the first half of 2026. The operating loss peaked at $8.060 billion in 2025 before narrowing to $693 million in the first half of 2026. Yet the net loss expanded in parallel to $80.748 billion. The operating measures improved while the net loss deteriorated, driven by different factors.

 

 

Of the $16.286 billion in first-half revenue, consumption-based fees accounted for roughly $13.1 billion, or 80%, with subscriptions at roughly $3.2 billion, or 20%. That split was 75% to 25% in 2024 and 83% to 17% in 2025.

 

The quarterly view is steeper. Revenue across the four quarters of 2025 came to $376 million, $787 million, $1.382 billion and $2.040 billion, followed by $4.731 billion in the first quarter of 2026 and $11.555 billion in the second. Second-quarter revenue grew roughly 1,368% year over year while compute and infrastructure expenses grew roughly 300% over the same span.

 

 

The second quarter turning positive at the operating line is the piece of this filing most easily buried by the $80.7 billion headline.

 

 

For the trailing twelve months ended September 30, 2026, customers contributing more than $100,000 in revenue numbered over 11,900, up from over 950 a year earlier, with more than 1,900 contributing over $1 million and roughly 250 contributing over $10 million. Net revenue retention stood at approximately 900% over the same period.

 

On concentration, the top five customers accounted for roughly 25% of revenue for the nine months ended September 30, 2026, with no single customer above 10%. The filing's risk factor summary also notes that "a substantial portion of our revenue and accounts receivable is driven by a limited number of customers and distribution channels," without finer percentages.

 

Distribution itself is a structural dependency. The filing states that Claude is accessed through AWS, GCP and Azure under a joint go-to-market approach, with a fee paid to each cloud service provider. Those same three are also principal counterparties to the compute commitments discussed below.

 

Measured by billing address, international revenue reached roughly $4.523 billion in the first half, around 28% of the total.

 

 

One company in one period can report three loss figures pointing in different directions. This is not a contradiction, since the three answer three different questions.

 

 

The bridge from operating loss to net loss reconciles item by item. The $693 million operating loss, plus $1.111 billion of interest income, less $72.388 billion of fair value change on convertible notes, derivative liabilities and SAFEs, less $8.757 billion of other expense net and $21 million of income tax, produces the $80.748 billion net loss.

 

The decisive item is that $72.388 billion. Convertible notes, derivative liabilities and SAFEs are carried at fair value, so when the company's valuation rises, the equity those instruments can convert into becomes more valuable, the carrying value of the corresponding liability rises, and the difference runs through the period's income statement as a loss. The filing attributes the movement specifically to an increase in the fair value of its outstanding convertible promissory notes.

 

The economic meaning of this charge therefore runs opposite to a loss in the ordinary sense: it records an increase in company value, accruing to early investors. Charges of this kind consume no cash, and they typically stop recurring once the instruments convert to common stock at IPO. The history bears out that it scales with valuation, rising from $1.045 billion in 2023 to $5.434 billion in 2024, $34.308 billion in 2025 and $72.388 billion in the first half of 2026.

 

On cash, operating activities provided $3.929 billion during the half while purchases of property and equipment took $482 million, leaving roughly $3.447 billion of free cash flow. Note that reporting indicates the company attributes part of the operating cash flow improvement to payment timing, so a single half year should not simply be annualised.

 

As of June 30, 2026, cash and cash equivalents stood at $112.4 billion with short-term investments of $19.3 billion, totalling $131.651 billion. Financing activities provided roughly $110.8 billion during the half, mostly from redeemable convertible preferred stock.

 

One further figure sits outside those three measures while shaping future statements. Personnel costs reached $3.152 billion in the half, including roughly $2.2 billion of stock-based compensation, while unrecognised restricted stock unit compensation stood at $26.6 billion as of June 30. That expense will enter the income statement across future periods, and although it likewise consumes no cash, it will weigh on future GAAP profit.

 

The company also discloses a non-GAAP adjusted operating income of positive $1.618 billion for the half, with adjustments covering stock-based compensation, non-cash charitable contributions and the Bartz settlement. Non-GAAP measures are defined by the company and are not directly comparable across peers.

 

 

This section needs the most care, because the most widely circulated figure is precisely the one the filing does not provide.

 

A passage in the public S-1's risk factors describes purchase commitments and lease agreements with the dollar amounts left blank. The aggregate committed spend, the amount expected to be incurred before December 31, 2030, and the amount due in the next twelve months all appear as blanks, with the text stating only that substantially all of it relates to compute and infrastructure and that substantially all of the remainder is expected between 2031 and 2045. The passage refers readers to the Contractual Obligations section of the MD&A.

 

The totals circulating in coverage therefore need to be sourced separately.

 

 

The per-contract amounts compiled by third parties include Broadcom TPU equipment leases at roughly $161.2 billion in rent excluding interest over five-year terms, SpaceXAI Nvidia GPUs at up to $120.5 billion into 2029, Google Cloud at at least roughly $114.5 billion from April 2026 to July 2033, AWS at at least $110.0 billion from May 2026 to April 2036, Microsoft Azure at at least roughly $44.9 billion from November 2026 to May 2033, Nscale Nvidia GPUs at up to roughly $44.6 billion into 2033, and Lambda at roughly $41.3 billion into 2034. Items without a fixed amount include additional TPU capacity estimated at $125.0 billion to $150.0 billion and AMD systems expected to exceed $20.0 billion.

 

These amounts are not the same kind of obligation. The Broadcom, Google, Amazon and Microsoft portions represent minimum spend or lease rent totalling roughly $431 billion, while the SpaceXAI, Nscale and Lambda portions are marked "up to" or billed on delivery, totalling roughly $206 billion. Adding the two categories overstates the firm obligation.

 

Set against $131.651 billion in cash and short-term investments, the firm obligations are substantially larger in magnitude, with payment timing extending to 2045. This is the substance of the filing's risk factors and the aspect of the company's financial structure most worth tracking. Assessing sustainability means watching whether revenue growth continues to outpace compute spending growth, and the first half compares favourably on that test: compute and infrastructure spending fell from 201% of revenue a year earlier to 55%.

 

 

As of this article's verification date of October 27, 2026, the following remain unsettled, so any valuation-based calculation should be treated as an assumption rather than a conclusion.

 

The share count, price range and total raise are absent from the filing, as is the split between company-issued and stockholder-sold shares. The registration statement has not become effective. Reporting suggests investor meetings could begin as early as the week of November 9, but that timetable is not company-confirmed.

 

The filing itself gives no valuation. Circulating figures come from media reports, including a roughly $965 billion private round in May 2026 reported by CNBC and an expected listing value above $2 trillion reported by NBC News. These are third-party reports rather than filing disclosures and should not be mixed with filing data.

 

The filing also lists several open matters, including a Federal Trade Commission investigation, a pending petition for en banc rehearing, and uncertainty over whether contractual liability caps would hold and whether insurance would cover agent-related liabilities.

 

Readers following pre-IPO trading should be clear on what the product is. A pre-IPO perpetual contract is not a share, confers no ownership, voting rights or dividends, and is priced off a custom index rather than an actual market trade price. For the routes to pre-listing exposure and the limits of each, see our comparison of three routes.

For James Mitchell, the item most worth writing up in this filing is not the $80.7 billion but the fact that $693 million and positive $3.929 billion were entirely obscured by it.

 

Of the $80.748 billion net loss, $72.388 billion came from remeasuring convertible notes, derivative liabilities and SAFEs, which the filing attributes to an increase in the fair value of its outstanding convertible promissory notes. The mechanism deserves thinking through: the more the company is worth, the more equity those early instruments can convert into, the higher the carrying value of the matching liability, and the larger the period's loss. The charge records a valuation increase rather than money leaving the business. It consumes no cash, and it typically disappears once those instruments convert at IPO. Reading it as evidence of operating failure is the most common misreading of this statement.

 

What deserves attention instead is three measures improving together. The operating loss narrowed from $2.135 billion a year earlier to $693 million. Second-quarter operating income turned positive at $974 million, the first positive figure in the six quarters shown. Operating cash flow swung from negative $1.513 billion to positive $3.929 billion. The clearest indicator of unit economics is compute and infrastructure spending as a share of revenue, down from 201% a year earlier to 55%, meaning revenue grew substantially faster than compute spending. Taken together, these describe a far more complicated picture than a massive loss.

 

I would not read the filing as an optimistic conclusion, though, because three risks carry enough magnitude to change the assessment.

 

The first is the comparison between purchase commitments and cash. Counting only firm obligations such as minimum spend and lease rent, third-party sums land around $431 billion against $131.651 billion in cash and short-term investments, with payment timing extending to 2045. Obligations of this kind do not shrink when revenue falls, which is precisely what separates them from variable costs.

 

The second is the $26.6 billion of unrecognised stock-based compensation. It consumes no cash yet will suppress GAAP profit across future periods, and the company's adjusted operating income excludes it. Anyone comparing adjusted figures should know what has been taken out.

 

The third is distribution dependency. Claude is distributed through AWS, GCP and Azure with a fee paid to each, and those same three are principal counterparties to the compute commitments. Suppliers and channels overlapping to that degree means a change in any one relationship would hit both the cost side and the revenue side at once.

 

On the commitment totals, one citation problem is worth flagging specifically. In that risk factor passage of the public S-1, the aggregate committed spend, the pre-2030 amount and the next-twelve-months amount are all blank. The roughly $637 billion widely quoted is a third party adding up individually disclosed contracts, and the roughly $518 billion is Reuters reporting earlier on the confidential version. Neither is a filing-stated total, and the first combines "minimum spend" and "up to" obligations that differ in kind. Until a price range is published, any cash-coverage calculation built on those totals carries wide error bars.

 

A closing word on valuation. The filing gives none, and the circulating $965 billion private valuation and above-$2 trillion listing expectation are both media reports. With the share count and price range blank, multiples such as price to earnings or price to sales cannot be calculated, and pre-IPO derivatives are priced off a custom index rather than any traded share price. That distinction matters more to anyone planning to trade the contract than any single line on the financial statements.

 

 

 

It depends which measure. Under US accounting rules, the net loss for the first half of 2026 was $80.748 billion. But the operating loss was only $693 million, narrower than the $2.135 billion a year earlier, and second-quarter operating income turned positive at $974 million. Operating cash flow was positive $3.929 billion against negative $1.513 billion a year earlier. At the operating and cash levels, the half showed improvement turning positive, while the large net loss came mostly from non-cash fair value remeasurement.

 

 

Because $72.388 billion of the net loss came from changes in the fair value of convertible notes, derivative liabilities and SAFEs, which the filing attributes to an increase in the fair value of its outstanding convertible promissory notes. These instruments are carried at fair value, so a rising company valuation raises the carrying value of the liability and the difference runs through income as a loss without any cash leaving. Adding $8.757 billion of other expense net brings non-operating items to roughly $80 billion, which is the bulk of the net loss.

 

 

Of the $16.286 billion in first-half 2026 revenue, consumption-based fees accounted for roughly $13.1 billion, or 80%, with subscriptions at roughly $3.2 billion, or 20%. Measured by billing address, international revenue was roughly $4.523 billion, around 28%. On customer numbers, more than 11,900 customers contributed over $100,000 on a trailing twelve-month basis as of September 30, 2026, with roughly 250 contributing over $10 million. Claude is also distributed through AWS, GCP and Azure, with a fee paid to each cloud provider.

 

 

The aggregate commitment figures in the public S-1 are blank, with the filing stating only that substantially all of it relates to compute and infrastructure and that substantially all of the remainder falls between 2031 and 2045. The roughly $637 billion cited in coverage is a third-party sum of individually disclosed contracts, and the roughly $518 billion comes from earlier Reuters reporting on the confidential filing. Within that third-party sum, roughly $431 billion represents minimum spend or lease obligations while roughly $206 billion is marked "up to" or billed on delivery, two categories that differ in kind and should not be combined.

 

 

As of June 30, 2026, cash and cash equivalents of $112.4 billion plus short-term investments of $19.3 billion totalled $131.651 billion. Third-party sums of firm purchase and lease obligations run substantially above that figure, though payment extends to 2045 rather than falling due at once. Assessing sustainability means tracking revenue growth against compute spending growth, and compute and infrastructure spending fell from 201% of revenue a year earlier to 55% in the first half.

 

 

Neither is determined. The filing gives no share count, price range or total raise, the registration statement has not become effective, and the split between company and stockholder shares is undisclosed. Reporting suggests investor meetings could begin as early as the week of November 9, though that timetable is not company-confirmed. The filing itself gives no valuation, and the circulating $965 billion private valuation and above-$2 trillion listing expectation both come from media reports.

 

 

Disclosed items include that a substantial portion of revenue and accounts receivable is driven by a limited number of customers and distribution channels, that purchase commitments extend to 2045, a Federal Trade Commission investigation, a pending petition for en banc rehearing, and uncertainty over whether contractual liability caps would hold and whether insurance would cover agent-related liabilities. Note also the $26.6 billion of unrecognised restricted stock unit compensation as of June 30, which will enter the income statement in future periods.

 

 

No. A pre-IPO perpetual is a derivative whose holder receives no shares, voting rights or dividends, and it is priced off a custom index rather than an actual market trade price, since no public share price exists before listing. With the share count and price range undetermined, valuation multiples such as price to sales cannot be calculated. How a contract is handled once the underlying lists is governed by each venue's rules, so the conversion terms and risk limits on the contract detail page should be checked before submitting an order.

The financial data cited comes from the Form S-1 registration statement filed publicly by Anthropic, PBC with the US Securities and Exchange Commission on October 26, 2026, and from third-party analyses of that document, verified on October 27, 2026; figures identified as third-party sums, media reports or analyst calculations are not figures stated in the filing, items left blank in the filing are identified as such in the text and should not be treated as zero or substituted with numbers from other sources. The registration statement has not become effective, the share count, price range, total raise and effective date are all undetermined, the filing's contents may be amended before effectiveness, and the securities may not be sold before the registration statement becomes effective. Valuation figures appearing in the text come from media reports rather than filing disclosures. The half-year financial data is unaudited, the company has attributed part of its operating cash flow improvement to payment timing so single-period figures should not be annualised, and non-GAAP measures are defined by the company with exclusions including stock-based compensation, making them non-comparable with other companies. The pre-IPO perpetual contract referenced is a derivative rather than a share, conferring no ownership, voting rights or dividends, priced off a custom index rather than a public market trade price, and leveraged products can produce losses exceeding the initial outlay, with handling in a listing scenario governed by venue rules. An initial public offering may not be completed, may be delayed, or may proceed on changed terms.
