Anthropic Files for a Nasdaq IPO With $16.3 Billion in Revenue and an $80.7 Billion Loss

we expect our Run-Rate Revenue growth rate to decline over time, and it may decline significantly and more rapidly than we anticipate

The $80.7 billion loss in Anthropic’s IPO filing is mostly an accounting entry for the company’s own valuation going up, and the number that deserves scrutiny is the price investors will be asked to pay for revenue that the filing itself says will slow. Anthropic filed its S-1 on October 26 to list on the Nasdaq as “ANT,” with Goldman Sachs and Morgan Stanley leading, and left the share count and price range blank. We read the filing and ran the quarterly figures ourselves. Here is the table that the headline coverage skips.

The Loss Is Mostly the Valuation Talking

Start with the line everyone quoted. For the six months ended June 30, Anthropic reported revenue of $16,286 million and a net loss of $80,748 million. Read that cold and it sounds like a company that burned five dollars for every dollar it earned. Now walk down the income statement the way the filing lays it out. The operating loss for the half was $693 million, about 4 percent of revenue. Interest income added $1,111 million. Then comes a line called change in fair value of convertible notes, derivative liabilities and SAFEs, which is $72,388 million, and a further $8,757 million of other expense that the filing ties to the initial fair value recognition of assets and liabilities under its note purchase agreements.

Here is the mechanism, and it is worth slowing down for. Anthropic raised money by issuing convertible notes and SAFEs, which are promises of future shares at a price set by an earlier valuation. When the company’s valuation climbs, those promises become more expensive to honor, and accounting rules make the company book the difference as a loss. The S-1 says so directly: the charge was “primarily driven by an increase in the fair value of our outstanding convertible promissory notes resulting from an increase in our enterprise valuation.” By our arithmetic, $72,388 million is 89.6 percent of the net loss. Take it out and what remains is roughly $8.4 billion, most of it that other-expense line. The same item was $34.3 billion in 2025. A company can book a record loss in the very half-year it becomes more valuable, and that is what happened here.

It follows that the loss headline tells you nothing about whether the business works. The table does. Compute was 251 percent of revenue in the first quarter of 2025 and 48 percent in the second quarter of 2026. Anthropic posted its first operating profit, $974 million, in the quarter revenue went from $4.7 billion to $11.6 billion. Net revenue retention was about 900 percent as of September 30, meaning customers who were there a year ago now spend roughly nine times as much. The operating numbers are unusual and they do hang together.

What $1.5 Trillion Asks You to Believe

The part that does not hang together yet is the price. Reuters reported on October 15 that some investors were weighing about $1.5 trillion, down from the roughly $2 trillion they had expected, after Anthropic told them third-quarter revenue was $16.8 billion, up 45 percent on the second quarter. That figure comes from the investor presentation and is not in the filing, whose financial statements stop at June 30. The previous quarter’s jump was 144 percent. Growth is still enormous, and it is less than a third of what it was one quarter earlier.

Annualize the third quarter and you get $67.2 billion. At $1.5 trillion, buyers would pay about 22 times that. At $2 trillion, about 30 times. The May private round at $965 billion works out to 14 times. The filing leaves its own run-rate figure blank and warns that the measure “annualizes a short measurement period,” so treat our 22 as a rough yardstick, not a forecast. OpenAI, for comparison, is nearing a $30 billion raise at $1.25 trillion. A $1.5 trillion Anthropic would be priced above it.

Then there is the bill. The filing leaves the total of its compute commitments blank. One analyst tally of the named contracts reaches about $637 billion, against $131.7 billion in cash and short-term investments on the balance sheet. That tally is the analyst’s sum, not a number Anthropic published, and we mark it that way. It still tells you the shape of the bet: the company has promised to buy far more computing than it has money for, and it is counting on the revenue curve to cover the gap.

Say you are a non-founder employee holding shares. The lock-up terms describe your week. Up to 10 percent of your holdings can be sold on the first trading day, and up to 45 percent by the time the company reports full-year 2026 results. Most IPOs make insiders wait 180 days. Here the people who know the business best can start selling before the first earnings call, while the public takes the other side.

Who Holds the Control

Our view is that the number to watch is not the loss or even the multiple. It is who gets a vote. A single Class F share, issued to an LLC of the seven co-founders, carries 50.1 percent of the vote on general stockholder matters. Every Class A share the public buys splits the remaining 49.9 percent. The Long-Term Benefit Trust elects a majority of the board. The filing calls the company a public benefit corporation and lists “catastrophic or existential risks to humanity” among its risk factors.

We do not know what the shares will cost, and nothing here tells you what to buy. What we can say is that public investors are being offered the economics of a $1.5 trillion company and none of the control, at a price that assumes growth the company has already told them is fading. That is a choice about power, and it should be priced as one.

The offering could begin trading as soon as mid-November, before Thanksgiving by most accounts, and could be the largest on record, a title SpaceX took only this June. Wait for the price range. Then do the division.
