Sometime on Monday evening, Reuters reporters opened a document Anthropic had filed with the SEC in confidence, and the first number anyone repeated was $42 billion. That was the net loss for 2025. By Tuesday morning the second line of every story said the same thing: most of it was an accounting charge, non-cash, nothing to see.
That second line is the one worth arguing with. Roughly $34 billion of the loss, Reuters reported in its exclusive on the prospectus, was “an accounting charge that reflected an increase in the estimated value of financing that could eventually turn into Anthropic shares.” Non-cash is accurate. Harmless is not. That charge measures how much of the company earlier backers have already been promised, and the $2 trillion price Anthropic’s investors want at listing is exactly the thing that makes it grow.
The headline number. Anthropic lost $42 billion in 2025 on revenue of about $4.6 billion, and its operating loss, stripped of liability writedowns, was a little over $8 billion.
The number that moves with the IPO price. About $34 billion of that loss is the rising value of financing that converts into Anthropic stock. Nobody paid it in cash. Somebody will pay it in dilution.
What the Filing Actually Shows
Start with the business, because the business is extraordinary. Revenue grew twelvefold last year. In the second quarter of 2026 alone Anthropic booked $11.5 billion, up 14 times on a year earlier and more than double all of 2025, and it reported a $559 million adjusted operating profit, its first. Fortune’s walk through the income statement puts Q1 revenue at $4.73 billion, so the company more than doubled its top line in a single quarter.
Then the obligations. Anthropic told prospective investors it plans to spend $518 billion on cloud, compute and infrastructure in the coming years. It held $20.28 billion in cash and short-term investments on December 31. Nearly a quarter of 2025 revenue came from two customers, and the filing warns that most large customers have no long-term contracts and could cut spending at any time. The risk section, as TechCrunch noted, goes further than any S-1 in memory: it lists models that “resist shutdown,” “conceal or manipulate information,” and behave in ways “resembling blackmail.”
That is the story most outlets ran, and it is true. It is also the version of the story that suits the people selling the stock. Read the loss as a scary headline that dissolves on inspection, fix your eyes on the adjusted operating profit, and the $2 trillion ask looks like a growth multiple rather than a transfer.
Who Pays for the $34 Billion
Here is the mechanism, in plain terms. When Anthropic raised money through instruments that convert into shares later, it recorded a liability. When the company’s value rises, the value of what it owes those holders rises with it, and under the accounting that applies, that increase runs through the income statement as a loss. Anthropic’s valuation climbed from $61.5 billion in March 2025 to $183 billion that September. The charge is the shadow of that climb.
Our read, and it is a read rather than a disclosure: if those instruments stay outstanding until the listing, the same mechanism keeps working through 2026. Anthropic has since been priced at $965 billion in its $65 billion Series H in May, and backers now talk about more than $2 trillion. Every dollar of that increase makes the claim of the earlier financiers bigger. The cash never moves. The ownership does, and the people who absorb it are the public buyers who show up at the top of the curve.
A higher IPO price does not shrink this charge. It is the thing that inflates it.
None of that makes Anthropic a bad business. A company that went from roughly $387 million of revenue in 2024 to $11.5 billion in one quarter of 2026 has earned serious attention, and it disclosed all of this itself, which is more candor than most listings offer. The criticism belongs with the framing. “Non-cash” has become a way of telling retail investors to skip the one line that describes how much of the company they are not buying.
What should happen is simple. When Anthropic files publicly, it should put the conversion math on one page: which instruments are outstanding, at what terms, how many shares they become at $1 trillion and at $2 trillion. The company has already delayed the listing past the November midterms to show one more quarter of revenue. It can spend some of that time showing the dilution table too, because the $518 billion of commitments means the public will be asked to fund this company again, probably more than once, and the first thing a buyer should know is how much of it was spoken for before they arrived.
