Anthropic IPO Valuation Faces Investor Pushback

Live Poll

Would you buy shares in a large AI company's IPO right now?

Potential investors are pushing down expectations for Anthropic's initial public offering, with some eyeing a valuation of $1.1 trillion to $1.3 trillion versus a recently floated $1.5 trillion. The pullback comes after the Nasdaq 100 fell 6.4% on Thursday, wiping out $2.3 trillion in market value.

Why it matters

The valuation debate tests investor appetite for a major AI company going public amid a sharp technology sell-off. Investors are also questioning whether a November listing is feasible.

Anthropic's prospectus shows about $895.4 billion in purchase commitments and lease agreements, including $69.8 billion due within twelve months, while its Q3 revenue was $17 billion, a 1,127% year-over-year increase. The final valuation and timing remain unsettled, and Anthropic left its October revenue figure blank in its updated S-1.

The players

Anthropic

Anthropic is an artificial intelligence company whose planned public listing is drawing scrutiny over its valuation and financial disclosures.

Vanda Research

Vanda Research is a firm that tracks retail investor trading activity and reported the strongest retail selling since the COVID-19 pandemic.

The details

More than 50 S&P 1500 technology stocks dropped 10% or more during the Thursday sell-off. Retail selling was the strongest it has been since the COVID-19 pandemic, according to Vanda Research, and Anthropic plans to kick off marketing the week of November 9.

Thursday: Nasdaq 100 plunged 6.4%, wiping out $2.3 trillion in market value.
July 2026: Anthropic's monthly revenue run rate was $65 billion.
October 2026: Annualized revenue run rate reached approximately $81 billion.
Week of November 9, 2026: Anthropic plans to begin roadshow marketing.

Market Dynamics

The Nasdaq 100's single-day loss of $2.3 trillion ties into retail selling that Vanda Research describes as the strongest since the COVID-19 pandemic, suggesting broad risk reduction rather than a company-specific reaction. A more skeptical public market may force Anthropic to prioritize revenue acceleration over infrastructure expansion.

Investors holding Nasdaq-linked index funds saw portfolio values fall sharply on Thursday as the 6.4% decline wiped out $2.3 trillion in market value. Anyone weighing exposure to a new AI listing should check how a lower valuation or delayed offering would affect expected returns.

The takeaway

A sharp index sell-off and a pricier-than-expected IPO can both shift risk appetite quickly, so reviewing how much of a portfolio is concentrated in technology stocks is a practical step. Waiting for the final offering terms before committing new money can reduce exposure to valuation swings.
