Anthropic's first profitable quarter came with a $66.3bn net loss

On May 20, 2026, The Wall Street Journal reported that Anthropic was on course for its first operating profit: $559 million in the quarter ending in June, on revenue expected to more than double to $10.9 billion. The figures were the company's own, shared with investors during a funding round. Anthropic's amended registration statement, filed with the US Securities and Exchange Commission on November 2, 2026, now puts line-by-line figures behind that forecast. For the three months ended June 30, 2026, Anthropic recorded operating income of $974 million on revenue of $11,555 million. On the measure the Journal described, the forecast was met, and exceeded.

The same filing shows a net loss of $66,309 million for that quarter, the largest of any quarter in the prospectus. It shows that the company returned to an operating loss of $567 million in the third quarter. And its risk factors state that Anthropic has "incurred net losses in each year since our founding" and "may not achieve or sustain profitability in the future." Was Anthropic profitable? The answer depends entirely on which line of the income statement is read, and the filing makes the distance between those lines measurable for the first time.

In Short

In May, a newspaper reported that Anthropic, the company behind Claude, expected its business to earn more than it cost to run for the first time between April and June. Its official paperwork for selling shares on the stock market now shows that it did, by more than forecast. But the same paperwork shows a giant overall loss for those months, because the IOUs Anthropic owes some investors became far more valuable as the company itself became more valuable. From July to September the business slipped back into a loss, although Anthropic's own adjusted measure, which leaves out pay and donations made in shares, stayed positive, so whether you call the company profitable depends on which of those numbers you choose.

What the Journal reported in May

The Journal's report ran under the headline "Mind-Blowing Growth Is About to Propel Anthropic Into Its First Profitable Quarter." The article sits behind a paywall; its contents below are as cited the same week by Investing.com, Engadget and the newsletter Where's Your Ed At, which reproduced several passages.

According to those accounts, the Journal reported that Anthropic generated $4.8 billion of revenue in the first quarter of 2026 and was set to more than double that to $10.9 billion in the second. Quarterly revenue, the paper said, was growing faster than Zoom's during the pandemic and faster than Google's and Facebook's in the run-up to their initial public offerings. Anthropic was set to turn an operating profit of $559 million in the June quarter, which Engadget described as the company's first profitable quarter since it was founded in 2021.

Three details in the report matter for any comparison with the filing.

The first is the measure. According to Investing.com's account, the operating profit figure included model training costs but excluded stock-based compensation. It was an operating number, not a net one. Nothing in any account of the report suggests the Journal described Anthropic as profitable on a net income basis.

The second is the status of the figure. It was a projection. On May 20, the June quarter still had six weeks to run. The numbers came from material Anthropic shared with prospective investors in an ongoing funding round, and none of the accounts quotes an Anthropic executive or spokesperson. Anthropic did not publish the forecast; investors received it, and the Journal reported it.

The third is the caveats. The Journal reported that the company might not remain profitable for the full year, because it planned to increase spending on computing. Engadget's summary was blunter, saying Anthropic did not expect to be profitable in the quarters that followed. Investing.com added that in the summer of 2025 Anthropic had told investors it did not expect full-year profitability until at least 2028. And, according to the passages reproduced by Where's Your Ed At, the Journal noted that it was unclear what accounting methods Anthropic had used to book revenue and costs, since the company was not yet bound by the reporting requirements of a public company.

The filing answers that caveat for the results, if not for the forecast. The prospectus, prepared under SEC rules and first filed publicly on October 26, sets out Anthropic's quarterly results line by line.

What the filing shows for the second quarter

The amended prospectus contains an unaudited quarterly statement of operations covering seven quarters, from the three months ended March 31, 2025 to the three months ended September 30, 2026. The table below sets the May report against it.

The management's discussion is direct about the second quarter: "we generated operating income of $1.0 billion for the three months ended June 30, 2026, as revenue growth outpaced the growth in total operating expenses."

The quarter's cost base totalled $10,581 million. Compute and infrastructure took $5,558 million, or 48% of revenue, the lowest share in any quarter of the filing. Personnel cost $1,857 million, including stock-based compensation of about $1.3 billion. Sales, marketing and partnerships, which the filing says rose mainly because of fees paid to channel partners, cost $2,135 million. Other operating and administrative costs were $1,031 million.

Comparing like with like

The forecast and the filing do not use the same yardstick, which matters for anyone reading the $559 million and the $974 million side by side.

Anthropic's filing defines Adjusted Operating Income as operating loss excluding "(i) stock-based compensation expense, (ii) non-cash charitable contributions, and (iii) the Bartz settlement," the $1.5 billion that ended the authors' copyright class action. In the second quarter there was no charitable charge and no settlement, so the adjusted figure is simply operating income plus stock-based compensation: $974 million plus $1,261 million, or $2,235 million, an adjusted margin of 19%.

If the Journal's figure excluded stock-based compensation, as Investing.com reported, the closest comparable number in the filing is that $2,235 million, about four times the forecast. Measured on the stricter GAAP basis, which counts share-based pay as a cost, operating income still came in $415 million, or 74%, above the forecast. On either reading, the second-quarter profit the Journal described did occur.

Revenue explains only part of the gap. By PPC Land's calculation, revenue exceeded the forecast by $655 million, or 6%, while adjusted operating income exceeded it by about $1,676 million. Either costs came in roughly $1 billion lower than the forecast assumed, or the forecast used a different definition from the one in the filing. The documents do not say which.

Training costs are inside the number

One persistent question about Anthropic's profit claims has been whether they leave out the cost of building models. For the operating figures, the filing answers it. Compute and infrastructure expenses support "the full range of workloads for our models, including research, model development, serving customers, and internal usage of Claude." The $974 million of operating income is calculated after the compute used to train models, not before it, which is consistent with Investing.com's account that the May forecast included model training costs.

Gross margin is a different matter. In September, the Financial Times reported, according to Reuters, that Anthropic's gross margins were above 80% before revenue shared with distribution partners, including Amazon, and before the cost of training its models. In October, Bloomberg reported that Anthropic told investors its gross margin was 85%. The prospectus reports no gross margin at all. It reports compute and infrastructure as a single line, equal to 48% of revenue in the second quarter and 58% in the third, and it does not split that line between training and inference. A gross margin above 80% can only be reached on a narrower cost base than the filing discloses, so the gross margin figures cannot be checked against it.

Was it the first time?

The Journal described the June quarter as Anthropic's first operating profit. The filing presents annual results from 2023 and quarterly results from the start of 2025, and every period before the second quarter of 2026 shows an operating loss: $551 million in 2023, $2,980 million in 2024, $8,060 million in 2025 and $1,667 million in the first quarter of 2026. The company's first two years, 2021 and 2022, are not in the filing. Nothing in it contradicts the "first" claim; nothing in it can confirm it for those two years either.

Below the operating line: a loss in every period

The headline phrase, first profitable quarter, is where the readings part company.

The second quarter's operating income of $974 million and interest income of $762 million were overwhelmed by two non-operating items. The change in fair value of convertible notes, derivative liabilities and SAFEs cost $59,597 million. Other expense, which the filing attributes "primarily" to "the initial fair value recognition and subsequent change in fair value of the assets and liabilities recognized under the partner financing arrangements," cost a further $8,448 million. The result was a pre-tax loss of $66,309 million and, with no material tax charge, a net loss of the same amount, equal to 5.7 times the quarter's revenue by PPC Land's calculation.

The timing is not coincidental. The filing says the fair-value expense "was largest in the three months ended June 30, 2026, reflecting the increase in our enterprise valuation in connection with our Series H financing." The dates line up with the funding round described in the May reports: between May and June 2026, Anthropic sold Series H preferred stock at $589.0095 a share for gross proceeds of $65.2 billion. If the profit forecast was part of that pitch, as the timing suggests, the same round that heard about the first operating profit also lifted the valuation that produced the largest net loss in any period the filing covers, larger even than the $41,965 million lost in the whole of 2025.

Figures in millions of US dollars, from the amended prospectus.

The fair-value charges are non-cash, and the instruments behind them will convert into shares. The filing's own Adjusted Net Income, which strips them out along with share-based pay and the charitable charges, was positive at $2,736 million in the second quarter and $3,167 million in the third. But the risk factors use the plain measure. "We have incurred net losses in each year since our founding, including net losses of $1.5 billion, $8.3 billion, and $42.0 billion for the years ended December 31, 2023, 2024, and 2025, respectively, and $104.0 billion for the nine months ended September 30, 2026, and we may not achieve or sustain profitability in the future." Further down the same passage, the filing is blunter still: "We expect our costs will increase over time and our losses will continue."

On net income, then, there is no profitable quarter in any period the prospectus covers. That does not contradict the Journal's May report, which described an operating profit. It does mean that a reader who took "first profitable quarter" to mean the bottom line would find the filing saying the opposite.

The Journal itself reported the bottom-line picture five months later. On October 20, according to Reuters, the paper reported from a draft prospectus that Anthropic's net loss exceeded $80 billion in the first half of 2026, driven by about $72 billion of accounting charges. The filing puts the half-year net loss at $80,748 million. PPC Land reported the public filing on October 26, when the same figures became available from the company directly.

The third quarter: the caveat arrives

The second profit claim concerned the three months to September.

On September 13, the Financial Times reported, according to Reuters, that Anthropic had told shareholders its adjusted operating income would be positive for a second straight quarter. On October 14, Anthropic presented to prospective investors at its San Francisco headquarters. Bloomberg reported, citing people familiar with the matter, that the company told investors it had achieved profitability in the quarter on an adjusted basis, that it was generating positive free cash flow, and that its adjusted operating margin was above 11%. Reuters reported the same adjusted profitability claim. The Journal reported the revenue figure: up 45% to $16.8 billion, according to people familiar with the matter. No account of the meeting names an Anthropic executive, and Reuters said the company did not respond to a request for comment.

The amended prospectus, filed 19 days later, shows third-quarter revenue of $16,956 million, $156 million more than the figure given to investors. It shows an operating loss of $567 million, a margin of minus 3%. And it shows Adjusted Operating Income of $2,463 million, a margin of 15%.

So both statements are true at once. The company was profitable on its adjusted measure, as it told investors, and loss-making on the GAAP operating measure. The reconciliation is short:

The $3,030 million gap between the two measures equals 17.9% of quarterly revenue by PPC Land's calculation. Both excluded items are settled in shares. The charitable charge "relates to non-cash charges from our donation matching program, the value of which is linked to employee equity awards," so it rises with the value of the stock.

The filing attributes the swing from second-quarter operating income to third-quarter loss "primarily" to "$5.0 billion of compute under short-term commitments, which currently costs significantly more than comparable compute procured under our multi-year commitments, and $2.0 billion of non-cash charges related to our donation matching program." PPC Land covered that amendment on November 2, including price reductions the filing values at about $600 million.

The May caveat, in other words, came true within one quarter on the GAAP measure. Spending on computing rose, and operating profit did not survive it. For the nine months, the operating loss was $1,260 million and Adjusted Operating Income was $4,081 million, a margin of 12%.

The other October claims can be partly checked. An adjusted operating margin above 11% is consistent with the 15% filed for the quarter and the 12% filed for nine months. The filing reports no free cash flow figure and no separate third-quarter cash flow statement. For the nine months, net cash provided by operating activities was $6,569 million and purchases of property and equipment were $925 million, which gives about $5.6 billion of free cash flow by PPC Land's calculation, or about $3.7 billion after a further $1,955 million of prepayments for leased assets and equipment. Positive on both counts, at least over nine months.

Where the claims and the filing diverge

Set side by side, the statements reported in 2026 and the filed figures line up as follows.

• First-quarter revenue. Reported in May as $4.8 billion; filed as $4,731 million. The difference of $69 million, about 1.4%, is close to rounding, and Reuters later reported the figure as $4.7 billion.
• Second-quarter operating profit. Forecast at $559 million; filed at $974 million GAAP and $2,235 million adjusted. No conflict: the result exceeded the forecast on both bases.
• "First profitable quarter" on a net basis. The second quarter carried a net loss of $66,309 million. This conflicts only with a bottom-line reading of "profitable," which the May report did not claim.
• Third-quarter profitability. Described to investors as profitable on an adjusted basis; filed as an operating loss of $567 million and Adjusted Operating Income of $2,463 million. The definition reconciles the two: $3,030 million of share-settled charges is excluded.
• Gross margin. Reported as above 80% (September) and 85% (October); not disclosed in the filing, where compute and infrastructure alone equal 58% of third-quarter revenue. The FT's account specified that its figure came before partner revenue sharing and training costs. The filing gives no way to verify either number.
• Full-year profitability. Flagged in May as uncertain; nine-month results show a GAAP operating loss of $1,260 million and positive adjusted operating income.

Apart from a $69 million difference in first-quarter revenue, none of the statements reported in the press is contradicted by the filing on the measure it named. Where they diverge from the filing, they diverge because a different measure produces a different answer.

What the evidence does not establish

Several questions remain open after the amendment.

How the forecast was built. The Journal itself said it was unclear what accounting methods Anthropic used. The filing shows what happened, not what investors were told would happen, and it cannot show whether the $559 million used the same cost categories as the prospectus. The $1 billion-scale gap between the forecast and the adjusted result points to a difference in either costs or definitions, without saying which.

Whether the second quarter was flattered by temporary pricing. Between May and October 2026, Anthropic signed and amended agreements with SpaceXAI, a subsidiary of SpaceX, for compute powered by Nvidia GPUs, with spending of up to $120.5 billion into 2029. The filing says the arrangements carry "different fees during capacity ramping periods" and reach about $3.1 billion a month once all capacity is delivered, which Anthropic expects in December 2026. At that rate, SpaceXAI alone would cost about $9.3 billion a quarter by PPC Land's calculation, equal to 94% of Anthropic's entire third-quarter compute and infrastructure expense. Where's Your Ed At argued on May 21 that the second-quarter profit relied on compute bought at reduced rates during the SpaceXAI ramp-up. The filing does not quantify the ramp-period fees, so it neither confirms nor rules out that argument.

What the fourth quarter will show. The amendment contains no fourth-quarter figures, and the Run-Rate Revenue it promises as of October 31, 2026 is still blank. For Anthropic to report a GAAP operating profit for the full year 2026, fourth-quarter operating income would need to exceed $1,260 million, by PPC Land's arithmetic.

What the stock-based compensation bill will look like after listing. The filing warns that expense related to restricted stock units "will result in increases in our expenses in future periods, in particular, in the quarter in which this offering is completed." The size of that charge is blank. Because it is excluded from the adjusted measure, it will widen the distance between Anthropic's adjusted and GAAP results, not narrow it.

Exactly what was said in May and October. Every account of both investor presentations relies on unnamed people familiar with the matter, and no Anthropic executive has been quoted on either forecast. The quarterly figures in the filing are themselves labelled unaudited.

Why it matters for the marketing community

Anthropic's revenue comes from customers paying to use Claude, through consumption and subscriptions, not from advertising, a point PPC Land examined when the filing went public. Those customers include marketing teams, agencies and the software vendors that serve them. That makes Anthropic's margins a pricing question for its customers. The amendment shows the company cutting prices worth about $600 million between the second and third quarters while its compute bill rose, and the filing ties its access to capital to its results: "Our ability to sustain access to capital depends in part on demonstrating a credible trajectory toward profitability." That sentence explains why the adjusted measure appears in investor presentations at all.

The net loss also has a mirror image on the balance sheets of the companies that sell advertising. The fair-value charges that turned Anthropic's operating profit into a $66.3 billion loss are, in part, the other side of gains booked by its investors. The filing carries Anthropic's convertible notes at a fair value of $130,502 million at September 30, against about $6.2 billion of principal outstanding on notes issued to Amazon, and Amazon's own earnings have included large gains tied to Anthropic. Amazon, Google and Microsoft each act as investor, supplier and sales channel, so when Anthropic's valuation rises, a hyperscaler can record a gain from the very change that adds to Anthropic's loss. Advertisers who read Amazon's and Alphabet's results for signals about ad pricing are, to a growing extent, reading Anthropic's share price.

Finally, there is the wider argument about whether artificial intelligence pays. Ray Dalio has said his bubble indicator puts AI level with 1929 and 2000; Apollo found no AI payoff in margins outside the technology sector; Barclays expects AI to supply 75% of S&P 500 earnings growth next year. Anthropic's prospectus offers detailed quarterly accounts from a company building a frontier model at this scale. It shows that such a company can earn an operating profit, as it did in the June quarter, and lose it again the next quarter by buying computing capacity at short notice. Both halves of that sentence will be quoted in the months ahead. The filing supports each of them, and neither on its own.

Summary

Who: Anthropic, the developer of Claude, which is preparing a Nasdaq listing under the symbol "ANT"; The Wall Street Journal, which reported its profit forecast in May and its first-half net loss in October; the Financial Times, Bloomberg and Reuters, which reported its later adjusted profitability claims.

What: A comparison of Anthropic's reported profit claims with its amended registration statement. The May forecast of a $559 million second-quarter operating profit was exceeded, with GAAP operating income of $974 million and Adjusted Operating Income of $2,235 million. The same quarter carried a net loss of $66,309 million, driven by fair-value charges linked to the Series H round. The third quarter, described to investors as profitable on an adjusted basis, produced Adjusted Operating Income of $2,463 million and a GAAP operating loss of $567 million.

When: The Journal's forecast report appeared on May 20, 2026; adjusted profitability claims followed on September 13 and October 14; the amended prospectus was filed on November 2, 2026, covering results to September 30, 2026.

Where: The investor presentations took place privately, including at Anthropic's San Francisco headquarters on October 14; the filing was made with the US Securities and Exchange Commission ahead of a planned listing on the Nasdaq Global Select Market.

Why: Anthropic's access to capital depends, in its own words, on "demonstrating a credible trajectory toward profitability," and the word profitable covers at least three different measures in its accounts. The filing confirms the operating profit claims on the measures they named, shows net losses in every period it covers, and leaves open whether the second quarter's margin can return once short-term and ramp-period compute costs are fully reflected.
