The Anthropic IPO moved a step closer on Monday, November 2, 2026, when the company behind the Claude chatbot filed an updated prospectus with the US Securities and Exchange Commission. The new numbers cover nine months instead of six. They show revenue of $33.2 billion through September 30, alongside spending promises that run close to $900 billion, according to Yahoo Finance.
Key facts (as of November 2026)
- Anthropic plans to list its shares on the Nasdaq under the ticker ANT, according to its public S-1 filing of October 26, 2026 (Yahoo Finance).
- The amended filing of November 2 reports $33.2 billion in revenue for the nine months to September 30, 2026, up 1,206% from a year earlier (Yahoo Finance).
- The company lists about $895.4 billion in total spending commitments, mostly for computing power and data centers (Yahoo Finance, gHacks).
What is the Anthropic IPO?
An IPO, or initial public offering, is the first time a private company sells shares to the public on a stock exchange. Anthropic is a San Francisco AI company. It makes the Claude family of AI models, plus tools such as Claude Code for programmers. CEO Dario Amodei co-founded it with his sister Daniela Amodei, who is the company’s president.
The company first made its prospectus public on October 26. That document, called an S-1, is the formal disclosure a company must file before it can sell stock in the US. It explains the business, the money and the risks. The version filed on November 2 is an amendment, so it updates the earlier numbers rather than starting over.
What changed in the amended filing?
In short, the new filing adds the July to September quarter. The original S-1 reported $16.3 billion in revenue for the first half of 2026. The update lifts the nine-month total to $33.2 billion. For comparison, Anthropic made $4.6 billion in all of 2025, Yahoo Finance reported.
Growth is still steep, but it is slowing. Third-quarter revenue came to nearly $17 billion, up 46% from the second quarter, gHacks reported from the filing. However, computing and infrastructure costs rose 77% over the same three months. The company itself warns that this pace of growth is unlikely to last.

Why did Anthropic swing to a loss last quarter?
In the July–September period, Anthropic lost $536 million at the operating level. Three months earlier, from April to June, it had earned $974 million on the same measure. The company blamed most of the swing on a $5 billion charge for short-term computing commitments. It also booked $2 billion in non-cash charges linked to its donation-matching program, according to Yahoo Finance.
Across the full nine months, the picture looks better than a year ago. The operating loss narrowed to $1.3 billion, compared with $5.2 billion in the same period of 2025.
How big are the Anthropic IPO spending commitments?
They are very large. The filing puts total committed spending at about $895.4 billion, mostly for computing power. Roughly $447.5 billion of that falls due by the end of 2030, and about $69.8 billion within the next 12 months, Yahoo Finance reported. gHacks noted the total was more than $800 billion only a week earlier.
Some of those contracts can’t be cancelled. According to gHacks, deals with Microsoft, Google, Amazon and Broadcom add up to $437 billion and are non-cancellable. The filing also says paying for this computing depends on strong revenue growth, so the company may need more debt or equity later.
Distribution is another theme. About 44% of revenue came through cloud marketplaces run by the big cloud providers, and no one customer makes up over a tenth of sales, gHacks reported. Those same providers also build or sell rival AI models, which the filing lists as a risk.
When could Anthropic shares start trading?
No date has been confirmed in the filings. Yahoo Finance reported that the stock could begin trading as soon as November 16, and investingLive reported the same target date. Neither filing story we reviewed included a share price range, which usually comes shortly before a listing.
The structure is unusual, too. According to investingLive, the company will have five classes of stock, and only the Class A shares will trade publicly. The filing also says Anthropic does not expect to pay dividends in the foreseeable future.
Two practical points for readers. First, an IPO date and price can change until the last minute. Second, nothing here is investment advice; the prospectus itself, filed with the SEC, is the primary document to read.
Does the Anthropic IPO change anything for Claude users?
Not directly. According to gHacks, the updated prospectus leaves Claude’s products and prices as they were for both users and developers. Its long risk section still describes ways AI models could cause harm, as the original did, according to Yahoo Finance.
