Anthropic IPO valuation drops to $1.3 trillion

Anthropic's planned initial public offering is being repriced in real time as market conditions deteriorate. According to Bloomberg, prospective investors are now discussing a valuation of $1.2 trillion to $1.3 trillion, a significant drop from the $1.4 trillion to $1.5 trillion range communicated to bankers just days earlier. This latest figure is far below the $2 trillion valuations floated in early October. The Wall Street Journal reported that three major prospective investors said the offering would need to be priced lower, with one suggesting a valuation closer to $1 trillion.

The reassessment follows a 6.4% plunge in the Nasdaq 100 on Thursday, which wiped 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, signaling heightened uncertainty. Anthropic's valuation expectations have retreated in three distinct steps: from $2 trillion in early October, to $1.4–1.5 trillion after an investor briefing on financial performance, and now to $1.2–1.3 trillion following Thursday's market rout. Bloomberg's reporting suggests investors and bankers are still working toward an offering rather than abandoning the timetable entirely.

The details

The company's amended S-1 filing reveals the scale of both the opportunity and the capital intensity driving this event. 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. The stock would trade on Nasdaq under the ticker ANT. Reuters reported the roadshow was expected to kick off the week of November 9, with pricing the following week. However, four people familiar with investor discussions said potential investors are raising doubts about whether Anthropic can proceed on that timeline. Investors are pushing for a more attractive valuation and are eagerly awaiting Anthropic's October revenue figure, which the company left blank in its updated S-1.

An independent evaluation by Model Evaluation and Threat Research (METR) adds technical context to the valuation debate. Given "unprecedented access to internal data" over roughly 11 weeks, METR estimated Anthropic is improving model capabilities on "well-specified tasks" around twice as fast as a year ago. METR said it was able to "confidently" rule out compute growth as the driver, guessing that the acceleration came from AI systems helping develop newer AI systems. However, METR noted caveats: the acceleration might be limited to tasks that can be graded automatically, not "messy" real-world tasks, and could reflect understatement of prior progress.

Context

CEO Dario Amodei publicly called for the industry to "slow the pace at which we improve the capabilities of AI models" in a September 12 essay, warning that recursive self-improvement could "outrun our ability to understand and control these systems." Amodei championed METR as an appropriate third-party evaluator, a stance supported by OpenAI's Sam Altman. This creates a tension between the company's public safety messaging and the aggressive capital raising required for its infrastructure commitments.

The broader tech sector is under pressure. 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. Microsoft tightened oversight of some data center projects from neocloud providers Nebius, IREN, and Nscale. Nebius, Iren, and CoreWeave have each lost roughly half their value over the past month, and CoreWeave and SpaceX credit default swaps hit records implying rising default expectations.

What it means for developers

For developers, the primary impact is indirect but significant. A lower valuation may signal a more sustainable funding environment for AI infrastructure, potentially reducing the risk of sudden service cuts or price hikes driven by capital constraints. However, the delay or repricing could also indicate tighter liquidity in the AI sector, which might affect the availability of cloud credits or API pricing stability. Developers relying on Anthropic's models should monitor the final IPO pricing and any changes in service level agreements, as the company's capital intensity is a key driver of its operational capacity.

What to watch

• October Revenue Figure: Investors are waiting for this number, which was left blank in the S-1, to gauge demand and growth rates.
• Roadshow Timeline: Whether the roadshop kicks off the week of November 9 as planned or is delayed.
• Final Valuation: The closing price of the IPO, which will set a benchmark for other AI companies seeking public funding.
• Sector Performance: Continued underperformance of tech stocks relative to the S&P 500 could further pressure AI valuations.
