Anthropic, the artificial intelligence company behind the Claude chatbot, filed for an initial public offering on Monday, October 26, 2026 — and its filing tells two stories at once. Revenue is exploding. Losses, on paper, are enormous. Understanding both numbers, and why they differ, is the key to understanding the biggest AI IPO yet attempted.
The headline numbers are these: revenue reached $16.3 billion in the six months ended June 30, 2026, up roughly 14-fold from $1.16 billion in the same period of 2025. Over the same six months, Anthropic reported a net loss of $80.7 billion. The company plans to list on the Nasdaq under the ticker “ANT,” but has not yet set the number of shares or the price range.
Why the $80.7 billion loss is misleading on its own
That giant net loss is not mainly cash Anthropic burned running its business. According to Reuters’ analysis of the filing, most of it comes from a non-operating item: the revaluation of bonds convertible into company shares. When a private company’s value rises sharply, the accounting value of those convertible instruments rises too, and that shows up as a loss — even though no cash left the building for it.
The operating picture looks very different. Anthropic’s operating loss narrowed to $693 million in the first half of 2026, from $2.1 billion a year earlier, while its adjusted operating income swung to a positive $1.62 billion, compared with a loss of $1.85 billion a year ago. Operating expenses were nearly $17 billion, of which $8.9 billion went to compute and infrastructure — the chips and data centres that train and run AI models. In plain terms: the core business is getting closer to profitable, even as the accounting headline looks alarming.
How fast is Anthropic really growing?
Very fast, by any measure — and the company itself warns not to extrapolate. Revenue was $41 million in 2023, $386 million in 2024 and $4.6 billion in 2025, before jumping to $16.3 billion in just the first half of 2026. The filing says revenue grew 1,300 percent year over year in that period, and also cautions: “We do not expect our revenue will continue to grow at comparable rates, and we cannot assure you that it will continue to grow at all.”
How big could this IPO be?
Reports, not the filing itself, put the possible valuation at $1.5 trillion to $2 trillion, and the amount raised at up to $100 billion — which would surpass the record set by SpaceX’s June IPO, reported at $86 billion. Those figures are unconfirmed: the filing sets no price range, and the final valuation will depend on investor demand.
Goldman Sachs and Morgan Stanley are leading a large underwriting syndicate that also includes J.P. Morgan, Citigroup, Barclays and Wells Fargo Securities.
Key takeaways
- Filed Oct. 26: Anthropic’s Form S-1 for a Nasdaq listing under “ANT”; shares and price not yet set.
- Revenue: $16.3 billion in the first half of 2026, versus $1.16 billion a year earlier.
- Net loss: $80.7 billion, largely a non-cash convertible-debt revaluation, not operating cash burn.
- Operating loss: narrowed to $693 million; adjusted operating income turned positive at $1.62 billion.
- Reported, unconfirmed: a $1.5–2 trillion valuation and up to $100 billion raised.
Bottom line: Do not judge this IPO by the $80.7 billion headline alone. Anthropic is growing at a historic pace and its operations are improving — but whether that growth justifies a trillion-dollar-plus valuation is the question investors must now answer.
