Anthropic Reported an $80.7 Billion Loss. The Real Story Is a Single Share

Anthropic lost $80.7 billion in the first half of 2026. It also made a record $16.3 billion.

Disclosure: this story concerns Anthropic, the maker of Claude.

Both numbers come from its IPO filing. They look like a contradiction. They are not. One is an accounting event. The other is a business.

The numbers, in order

Anthropic made its Form S-1 public on 26 October 2026 and plans to list on Nasdaq under the ticker ANT, The Next Web reports. First-half revenue was $16.3 billion, up from $1.16 billion a year earlier. Second-quarter revenue was $11.6 billion, with a first operating profit of $974 million.

Now the loss. Net loss for the half was $80.7 billion. The same report says it was mostly non-cash. It names $72.4 billion from revaluing convertible notes. It also names $8.8 billion tied to note purchase agreements with Google and Amazon.

A non-cash charge does not take money out of the bank. Think of a house that rises in value. Your paper wealth jumps, but your salary stays the same. Here the effect runs the other way. When the value of Anthropic rose, the notes it owed became more expensive on paper.

One caution on the arithmetic. The two charges, added together, exceed the net loss. We therefore quote each as reported and do not add them. We cannot say how the filing reconciles them without opening it.

A business that buys like a giant

The filing also lists customers. More than 11,900 pay at least $100,000 a year, up from about 950. About 250 pay over $10 million. The top five customers made about 25% of revenue in the nine months to 30 September.

Net revenue retention was about 900%. In plain terms, customers who stayed spent roughly nine times as much as before. That is rare, and it also shows how new the business is.

The spending side is just as large. The report lists minimum compute commitments of at least $114.5 billion to Google, at least $110 billion to Amazon and at least $44.9 billion to Microsoft. It adds about $161.2 billion in Broadcom equipment leases.

The Amazon figure matches Fortune’s reporting, which says Anthropic committed to at least $110 billion on AWS from May 2026 through April 2036. The total across providers was left blank in the filing.

But here is the twist: one share

Now the part most headlines skipped. The seven co-founders hold 50.1% of the votes on ordinary shareholder matters through a single Class F share, The Next Web reports. New share issues do not dilute that stake.

A second structure sits beside it. The Long-Term Benefit Trust elects the majority of the board through a Class T share. The article concludes that buyers of Class A shares will, in practice, be unable to decide shareholder votes.

So the IPO sells a slice of the economics, not the control. That is not new in tech. It is unusual for a company that may be valued in the trillions.

What the market is being asked to price

The Wall Street Journal, as relayed by The Next Web, says the target is the week of 16 November. It reports a possible raise of $100 billion or more at a valuation of $1.5 trillion to $2 trillion. The Next Web says it did not verify that. Treat the valuation as reported, not confirmed.

The Financial Times, per the same source, reported third-quarter revenue of $16.8 billion. The filing left that figure blank.

Investors will weigh three things. They will weigh the growth, which is extraordinary. They will weigh the commitments, which are fixed. And they will weigh the governance, which is closed.

Cash, funding and risk

The balance sheet is the other half of the picture. The Next Web reports that Anthropic has raised $141.1 billion in total. It held $112.4 billion in cash at 30 June, plus $19.3 billion in short-term investments.

That is a large cushion. It helps explain how a company can promise tens of billions in compute without panic.

Growth has been steep. The filing coverage shows 2025 revenue of $4.6 billion, and a roundup of the S-1 coverage lists 2024 revenue of $386 million. Treat the 2024 figure as single-source. CNBC’s live coverage is the place to cross-check it.

One risk line stands out. Between 5% and 7% of revenue in the nine months came from customers who broke Anthropic’s usage policy or terms, The Next Web reports. The filing coverage does not say what happened to that revenue.

The same roundup reports that usage-based revenue was $13.1 billion, about 80% of the half-year total. That means most revenue moves with customer activity. It is not locked in by contract.

Put those facts side by side. Costs are fixed by commitments. Most revenue varies with usage. That mismatch is the core financial risk, and the filing’s own risk section is the place to read more about it.

What we think

Our reading is this. The headline loss is the least useful number in the filing. The commitments are the most useful. They show a company that has already promised about $269 billion to three cloud providers, before counting the Broadcom leases.

That fits what we wrote about Anthropic’s custom chips as a margin play. Compute is the cost that decides everything. A company that must pay for compute on a fixed schedule needs revenue to grow just as fast.

It also connects to our view that AI is becoming an infrastructure problem. The model is the product. The data centre is the business.

What to watch next

Watch the price range, which the filing left blank. Watch whether the listing happens on the reported schedule. And watch how the market treats a founder-controlled structure at this scale.

If revenue keeps growing at this pace, the commitments look manageable. If it slows, they become the story.

The short version

Anthropic’s filing shows a company with fast revenue growth and very large fixed commitments. The $80.7 billion loss is mostly a non-cash revaluation. The cash cushion is big. The governance is tightly held by the founders and a trust.

None of this tells us how the market will price the shares. It does tell us what the buyers will be asked to accept. Read the filing itself if you plan to invest, and remember that we are not financial advisers.
