The AI IPO Wave: Anthropic’s Market Signals

When a company delays its IPO amidst AI safety concerns and sliding tech stocks, it’s a stark signal from the market. The extraordinary revenue forecasts and underlying risks raise questions about valuations and long-term viability in the AI sector.

When a company delays its IPO to show investors better numbers, that’s a strategy. When the NYC pension fund publicly asks you to delay it over AI safety concerns, your chief rival’s CEO calls his own IPO “ill-advised” and postpones it until at least next year, tech stocks are sliding on open-weight model fears, and your own prospectus warns of “existential risks to humanity” from the product you’re selling, that’s not a strategy.

That’s a market sending you a message.

Anthropic's Financial Insight

Anthropic’s numbers are extraordinary. Its third-quarter 2026 revenue was reportedly $16.8 billion — up 45% quarter on quarter. That means the company’s annualized revenue run rate is roughly $67 billion.

What the S-1 Actually Says

Here are the numbers from Anthropic’s leaked prospectus:

$4.6 billion: Anthropic’s full-year 2025 revenue.
$7.33 billion: What Anthropic spent on compute and infrastructure in 2025 alone — more than its total revenue.
$42 billion: Anthropic’s net loss in 2025. The roadshow will immediately explain that $34 billion of it was a noncash accounting charge.
$518 billion: How much Anthropic expects to spend on AI infrastructure over the course of a decade.
$2 trillion: That’s the IPO valuation Anthropic is still targeting for November, a figure representing 435x its 2025 revenue.

One more number from the S-1 that the roadshow will bury: A quarter of Anthropic’s 2025 revenue came from two unnamed customers.

Three Signals the Market is Sending

The IPO delay is the headline. It isn’t the only signal worth reading.

Signal one: NYC Comptroller Mark Levine. Last week, the supervisor of New York City’s pension funds asked Anthropic CEO Dario Amodei to pause the IPO entirely due to risks.

Signal two: Sam Altman delays OpenAI’s IPO. CEO Altman called an IPO at this moment “ill-advised” given AI safety concerns.

Signal three: The chip selloff. Last week’s $2 trillion chip-stock selloff was driven partly by concern over AI-buildout costs.

The Open-Weight Problem

Here is the structural argument: Anthropic’s $2 trillion valuation requires closed-model AI to maintain a durable pricing premium. That premium is being systematically dismantled.

Open-weight AI is challenging the economics behind closed-model valuations. Many companies report significant cost savings from open-weight models, highlighting the impending challenges that closed models may face.

Why This is Worse Than 1999

The dot-com bubble had a genuine excuse. The AI IPO wave of 2026 does not. The context in which Anthropic is asking investors to pay 435x revenue raises substantial questions about its valuation and long-term roadmap.

What Actually Survives This Correction

AI investors must recognize that real technology does not automatically justify its valuation. A strong quarter and a one-month delay do not close that gap. November simply gives Anthropic more time to explain the math.
