Anthropic IPO Valuation Talks Drop to $1.3 Trillion

Anthropic is now discussing an initial public offering valuation of $1.2 trillion to $1.3 trillion, according to epyhia.com, down sharply from the range it had communicated to bankers days earlier. The repricing matters because Anthropic could become the first frontier AI model developer to go public, and how investors price its growth against its enormous infrastructure commitments will set a benchmark for the sector.

What valuation is Anthropic now discussing?

According to epyhia.com, prospective investors are discussing $1.2 trillion to $1.3 trillion. That replaces the $1.4 trillion to $1.5 trillion range communicated to bankers just days earlier, and is far below $2 trillion figures floated in early October, Bloomberg reported Friday according to Investing.com, as cited by epyhia.com.

The Wall Street Journal reported Thursday, as cited by epyhia.com, that three major prospective investors said the offering would need a lower price, with one suggesting a valuation closer to $1 trillion. Epyhia.com reports that Bloomberg's reporting suggests investors and bankers are still working toward an offering rather than abandoning the timetable. Anthropic declined to comment on the valuation discussions, according to epyhia.com.

The trajectory described by epyhia.com is therefore a sequence of retreats: $2 trillion in early October discussions, then $1.4 trillion to $1.5 trillion after an investor briefing on financial performance, then $1.2 trillion to $1.3 trillion after Thursday's market fall.

Why did the valuation fall so quickly?

Epyhia.com attributes the latest revision to Thursday's market rout. The Nasdaq 100 fell 6.4% that day, wiping out roughly $2.3 trillion in market value in what epyhia.com describes as its largest single-day decline on record. The Cboe Volatility Index climbed to its highest level since April 2025, according to epyhia.com.

Broader market pressure is part of the context in the source material. Epyhia.com reports that tech stocks have underperformed the S&P 500 by 10.7% over the past month, the most extreme one-month underperformance since May 2002, according to Truist Advisory Services. Vanda Research said retail selling was the strongest since the COVID-19 pandemic, according to epyhia.com.

Investor doubts are not limited to price. Reuters reported, as cited by epyhia.com, that a roadshow was expected to kick off the week of November 9, with pricing the following week. Four people familiar with investor discussions told Reuters, according to epyhia.com, that potential investors are raising doubts about whether Anthropic can proceed on that timeline. Investors are also waiting for Anthropic's October revenue figure, which the company left blank in its updated S-1, according to epyhia.com.

What do Anthropic's amended S-1 numbers show?

Epyhia.com summarises the amended S-1 filing as showing both rapid revenue growth and very large losses and commitments. Revenue was $17 billion in Q3 2026, up 12 times year over year, according to epyhia.com. Nine-month revenue was $33.24 billion, giving an annualized run rate of about $68 billion, according to epyhia.com.

The net loss was $23.3 billion in Q3 and $104 billion for the first nine months, according to epyhia.com. Epyhia.com notes that 90% of the first-half loss — $72.4 billion of $80.5 billion — came from fair-value remeasurement of convertible notes, primarily from Amazon, whose carrying value rises as Anthropic's valuation climbs. Epyhia.com says this accounting effect largely disappears after the IPO when notes convert to equity.

Operating performance was closer to break-even in Q3, with $17.5 billion in operating expenses against $17 billion in revenue, according to epyhia.com. Q2 showed about $974 million in operating profit, operating cash flow was positive $3.9 billion in the first half, reports suggest free cash flow turned positive in Q3, and gross margin was about 85%, according to epyhia.com.

The capital intensity is the central question for public investors. Epyhia.com reports $895.4 billion in purchase and lease agreements, substantially all for compute and infrastructure. About $447.5 billion is due by the end of 2030, and about $69.8 billion is due in the 12 months after September 30, 2026, according to epyhia.com. Epyhia.com notes that near-term obligation is roughly four times current quarterly revenue.

Epyhia.com reports the IPO, led by Goldman Sachs and Morgan Stanley with 20 other banks, aims to raise at least as much as SpaceX's record $86.2 billion debut, and the stock would trade on Nasdaq under ticker ANT. Whether public investors will fund a capital plan extending far into the future, and how much of the $895.4 billion is firm versus contingent, remain unknown, according to epyhia.com.

What did METR find about faster model improvement?

An independent evaluation by Model Evaluation and Threat Research, known as METR, estimated Anthropic is improving model capabilities on well-specified tasks around twice as fast as a year ago, according to epyhia.com. METR had unprecedented access to internal data over roughly 11 weeks, from mid-August through late October, according to epyhia.com.

METR said it could confidently rule out compute growth as the driver, according to epyhia.com. Its guess was that acceleration came from AI systems helping develop newer AI systems, the closing-the-loop dynamic Anthropic describes in its filing, according to epyhia.com.

The caveats are significant. METR said the acceleration might be limited to tasks that can be graded automatically, not messy real-world tasks, according to epyhia.com. It could also reflect understatement of prior progress, and internal disagreements and uncertainty among METR's team were noted, according to epyhia.com. Anthropic did not respond to requests for comment on the report, according to epyhia.com.

Epyhia.com also notes that CEO Dario Amodei publicly called in a September 12 essay for the industry to slow the pace at which we improve the capabilities of AI models, warning that recursive self-improvement could outrun our ability to understand and control these systems. Amodei championed METR as an appropriate third-party evaluator, and OpenAI's Sam Altman also supported the idea, according to epyhia.com.

How does this relate to Grafy?

For readers trying to assess a filing of this size, the practical task is document-heavy: comparing revenue, losses, commitments and risk factors across a long S-1 without losing track of which figure came from which section. That is a genuine fit for Grafy Reader, where you can read, search and question PDFs and papers with AI, and for the guide on a reading room for papers if you want to see how that workflow is structured.

If you want to explore the underlying concepts — accounting remeasurements, IPO pricing, or what a run rate does and does not prove — Grafy Chat lets you chat with many AI models side by side and compare explanations. Grafy does not offer investment advice, and none of the figures in this article should be treated as a recommendation.

Politically, epyhia.com reports that ballot measures in multiple states limiting data center development have crystallised opposition to AI infrastructure, and that Microsoft tightened oversight of some data center projects from neocloud providers Nebius, IREN and Nscale, Bloomberg reported Thursday. Nebius, IREN and CoreWeave have each lost roughly half their value over the past month, according to epyhia.com, and CoreWeave and SpaceX credit default swaps hit records implying rising default expectations.

Whether Anthropic proceeds at $1.2 trillion to $1.3 trillion, seeks a smaller raise, or delays past Thanksgiving remains unknown, according to epyhia.com. The distinction between a repricing and a postponement matters, epyhia.com notes: going public at a more grounded valuation would test whether demand for leading AI businesses survives a sector correction.

Frequently asked questions

Did Anthropic comment on the valuation discussions?

No. According to epyhia.com, Anthropic declined to comment on the valuation discussions. The company also did not respond to requests for comment on the METR report, according to epyhia.com. That lack of comment is why the article attributes the valuation ranges to Bloomberg and The Wall Street Journal reporting rather than to Anthropic itself.

Did METR say compute growth drove the faster model improvement?

No. METR said it was able to confidently rule out compute growth as the driver, according to epyhia.com. Its guess was that AI systems helping develop newer AI systems explained the acceleration. METR also cautioned that the improvement might be limited to automatically graded tasks rather than messy real-world work.

Was Thursday's Nasdaq 100 fall the largest single-day decline on record?

Yes, according to epyhia.com. The Nasdaq 100 plunged 6.4% on Thursday, wiping out roughly $2.3 trillion in market value in its largest single-day decline on record. The Cboe Volatility Index climbed to its highest level since April 2025, according to epyhia.com, underscoring the market stress behind the repricing.
