If the reports are right, the biggest stock market listing in history is five weeks away. Anthropic, the company behind Claude, is said to be targeting a Nasdaq debut in November 2026 at a valuation of up to $2 trillion. "Anthropic IPO" has been climbing in India too, where retail investors have learned to follow US tech listings. Here is what is actually known.
What has been reported
The Wall Street Journal and Reuters report that Anthropic is aiming to list on Nasdaq in November, with the week of 9 November mentioned as the earliest window. The valuation under discussion is between $1.8 trillion and $2 trillion, and the amount raised could reach $100 billion. Anthropic has not confirmed a date, a price or a size.
What is on the record
Anthropic filed a confidential draft registration statement, the S-1, with the US Securities and Exchange Commission on 1 June 2026. Confidential filings let a company work through regulatory review before publishing. Its most recent private funding round, a Series H in May 2026, valued it at $965 billion. The reported IPO valuation would roughly double that in six months.
Why the numbers are so large
Anthropic's revenue has grown with enterprise adoption of Claude, and the company has positioned itself as the safety-focused lab, a stance that has become a commercial asset as governments move towards oversight. A $2 trillion valuation would put it alongside Nvidia, Microsoft and Apple. A $100 billion raise would exceed Saudi Aramco's 2019 record of about $29 billion by a wide margin.
The timeline to watch
- Public S-1: the company must file its prospectus publicly at least 15 days before its roadshow. That filing will reveal revenue, losses and the proposed price range.
- Roadshow: typically one to two weeks of investor meetings.
- Pricing: the night before trading begins.
- First trade: reportedly the week of 9 November at the earliest, before the US Thanksgiving holiday.
For investors in India
Indian retail investors cannot subscribe to a US IPO at the offer price. Shares become accessible through international brokerages once trading begins, within the Reserve Bank's annual overseas remittance limit of $250,000 per person. Early trading in large IPOs is volatile, and the first-day price is often well above the offer price.
