Anthropic Files for Nasdaq IPO Targeting Up to $2 Trillion Valuation

Anthropic filed for an initial public offering with the U.S. Securities and Exchange Commission on October 26 (local time), targeting a Nasdaq listing under the ticker 'ANT' at a valuation that could reach $2 trillion. Goldman Sachs and Morgan Stanley are lead underwriters, and Wall Street expects the listing as early as mid-November.

The filing makes Anthropic the first leading AI-era startup to enter the public stock market. Founded in 2021 by former OpenAI researchers, the company is led by CEO Dario Amodei and his sister, President Daniela Amodei. It built the Claude AI model and has accelerated growth by focusing on enterprise AI and specialized coding tools for software development.

What do the filed numbers show?

The S-1 lays out explosive growth. Revenue for the first half of this year hit $16.286 billion, a 14-fold jump from $1.163 billion in the same period last year. Before that, the trajectory was steep but small: $41 million in annual revenue in 2023, $386 million in 2024, and $4.585 billion in 2025. The first half of 2026 alone surpassed 3.5 times the full-year 2025 figure.

The losses are bigger still. Anthropic posted a net loss of $80.748 billion for the first half of 2026, more than six times the $12.969 billion recorded a year earlier. That figure includes non-cash valuation losses from convertible bonds and derivatives triggered by the company's rising corporate value. Operating loss, which reflects core business profitability, stood at $693 million.

Compute costs explain much of the burn. The company spent $8.945 billion on computing and infrastructure in the first half of 2026, nearly four times the $2.334 billion spent in the same period last year. As models grow more advanced and user bases expand, semiconductor and data center expenses keep climbing.

Who is paying for Claude?

Corporate clients drive the growth. As of the end of September 2026, Anthropic counted more than 11,900 customers who paid over $100,000 each in the preceding 12 months. Enterprises are adopting AI not just for document summarization or query answering but as tools for software development and operational workflows, fueling revenue growth.

Based on that momentum, analysts estimate Anthropic's valuation between $1.5 trillion and $2 trillion. A $2 trillion pricing at the IPO would rank it among the world's largest companies, on par with Meta.

Why does this IPO matter beyond one company?

The listing is a critical test of Wall Street's confidence in the AI industry. Big Tech and AI startups are pouring astronomical sums into data centers and semiconductors, and investors worry costs may outweigh returns. A successful IPO at a high valuation would signal enduring optimism, while a lower-than-expected price or post-listing underperformance could hit valuations of private AI firms.

U.S. Axios analyzed: "Anthropic's IPO will test Wall Street's sentiment toward the AI industry. A successful listing could ease investor anxieties about the sustainability of the AI investment boom, but mounting market pressures are adding to the challenge."

The filing also details AI-related risks in unusually direct terms. Anthropic warned that high-performance AI models could exhibit unintended behaviors or cause harm to external systems, and said insurance might not cover all potential losses from severe AI incidents. A company that has positioned AI safety as a core value spelled out those technological risks to public investors.

If the mid-November window holds, markets will get their first direct read on what public money will pay for frontier AI growth at a $2 trillion scale.
