Anthropic's IPO Price Tag Swung From $2 Trillion to $144 Billion in Two Weeks. Here's Why
That's not a typo spread. It's the difference between the largest IPO in history and a company worth roughly one-seventh of its last private valuation. Both claims are circulating in the same week, from people who have actually looked at Anthropic's numbers.
The confusion comes from two different questions getting mixed together: what is Anthropic's revenue actually doing, and what multiple should the market put on it. The two sides agree on almost nothing.
The number everyone agrees on
| Milestone | Date | Figure |
|---|---|---|
| Series G | Feb 2026 | $14B run-rate revenue |
| Series H (last private round) | May 2026 | $965B post-money valuation, $47B run-rate revenue |
| Reported run-rate (via Bloomberg sourcing) | Jul 2026 | ~$65B |
That trajectory, run-rate revenue roughly 5x-ing between February and May, is why anyone is talking about a trillion-dollar IPO at all. It's also reported, not audited: Anthropic doesn't publish financials, and the July figure rests on Bloomberg's sourcing via people familiar with the matter, not a company statement.
The bull, the bear, and the middle
The bull case: $2.4 trillion
An early Anthropic backer's prediction
- ✦Reported by Fortune on October 15, 2026
- ✦Would top SpaceX as the largest IPO pop on record
- ✦Rests on revenue growth continuing at its 2026 pace, not slowing
The middle: $1.5 trillion
What some current and prospective investors are now modeling
- ✦Reported by Reuters on October 15, 2026, relayed by 24/7 Wall St
- ✦Still 55% above the last private valuation
- ✦Reflects caution, not a rejection of growth
The bear case: $144 billion
Independent research firm New Constructs' low-end model
- ✦Built on a reverse discounted cash flow, working backward from price to required profit
- ✦93% below the $2 trillion target, per The Next Web's coverage
- ✦Cites a leaked prospectus showing $4.6B 2025 revenue against a $42B net loss
New Constructs isn't disputing that Anthropic is growing. It's disputing that growth alone justifies the price, calling the IPO target '2.0x NVIDIA's $184 billion and 2.6x Apple's $136 billion' in trailing profit for a company that, by its read, doesn't yet have a proven path to that kind of margin.
What's actually settled, and what isn't
- ✦The underwriters are real. Morgan Stanley, Goldman Sachs, and JPMorgan are reportedly leading the offering.
- ✦The timing has already slipped once. Reporting through August pointed to an October listing. By mid-October, Bloomberg's reporting (as relayed in subsequent coverage) pointed to mid-November instead.
- ✦No price range has been filed on EDGAR. Every dollar figure in this piece, including Anthropic's own reported target, is pre-filing.
- ✦The loss figure is contested. At least one critic of New Constructs' report notes its loss numbers reportedly draw on 2025 data even where 2026 figures exist, which some coverage of the report missed.
Has Anthropic actually filed to go public?
Not publicly. No S-1 has appeared on EDGAR as of this writing. Reporting describes a confidential draft registration and investor conversations, not a completed public filing.
What is Anthropic actually worth right now?
The only confirmed number is $965 billion post-money, set by its May 2026 Series H funding round. Every figure above that, including the widely reported $2 trillion IPO target, is a forecast or a model, not a transaction.
Why does one research firm say Anthropic is worth $144 billion?
New Constructs built a reverse discounted cash flow model working backward from the $2 trillion target to the profit margins it would require, and concluded Anthropic's current financials don't support it. $144 billion is the low end of its range, not a single-point estimate.
When is the Anthropic IPO actually happening?
Originally reported for October 2026, then pushed to a mid-November target per Bloomberg's reporting as of mid-October. Neither date is a confirmed filing, so both should be treated as moving targets.
How fast is Anthropic's revenue actually growing?
Reported run-rate revenue went from about $14 billion in February 2026 to $47 billion at its May Series H announcement, and was reported at roughly $65 billion by July per Bloomberg's sourcing. None of these figures are audited or company-disclosed.
