Quick Answer
When Is Anthropic Going Public? Anthropic, the company behind the Claude AI chatbot, has set its IPO price between $70 and $78 a share. As things stand in mid-November 2026, shares are expected to be priced on 18 November, with trading starting on the Nasdaq the next day under the ticker ANT. At the top of that range, Anthropic’s fully diluted valuation would sit at around $1.4 trillion. This is a fast-moving story, so treat the exact date and price as subject to last-minute change.
What Is Anthropic, in Plain Terms?
Anthropic develops Claude, an AI assistant that helps businesses and individuals write, code and answer questions. The company was founded in 2021 by a team of former employees at OpenAI, the company behind ChatGPT. Since then it has quickly developed and grown its valuation. By going public, the company will issue shares for the first time on the stock market, allowing regular investors to get a slice of the company.
When Is the Anthropic IPO Happening?
Here is where things stand right now. Anthropic filed a confidential draft paper with American regulators (called an S-1) back in June 2026 to start the IPO process. That filing became public this month, and the company has now set real numbers. Based on current reporting, the plan looks like this:
- Price range: $70 to $78 per share
- Pricing date: 18 November 2026
- First day of trading: 19 November 2026, on the Nasdaq
- Stock ticker: ANT
Keep in mind that IPO timelines often shift by a day or two, and the final price can land anywhere in or even outside the announced range, depending on investor demand.
How Much Is Anthropic Actually Worth?
Now this is where things get a little confusing. Let us explain.
If we take the share price and multiply it by the total number of shares that will be issued after the IPO then at the larger end of the range, Anthropic will be valued at $1 trillion, according to Reuters. However, most companies also include employee and grant options. This gives a ‘Fully Diluted’ valuation. According to the Financial Times, at the higher end of the range, Anthropic will be valued at between 1.26-1.41 trillion.
Therefore, when reading that Anthropic will be valued at $1 trillion in one article, but $1.4 trillion in another, both can be correct.
Anthropic was last valued at $965 billion back in May 2026. This was after raising $65 billion from investors in a round known as Series H. The IPO range is based off this figure.
It should also be noted that this is lower than the roughly $2 trillion that some investors and analysts were talking about earlier in 2026. However, whilst it may seem like a lower than expected valuation, many are viewing this as a smart move. This will allow the share price to increase once it starts trading. If it had been set higher then initial investors may be disappointed.
How Much Money Will Anthropic Raise?
Besides setting a valuation, the IPO is also how Anthropic raises fresh cash. Reports suggest:
- The main public share sale could raise as much as $64.4 billion
- A separate private placement with big investment partners could add another $26 billion
- All told, the company and its backers are aiming for close to $90 billion, and possibly nearer $100 billion if an extra option (known as a greenshoe) is used
That’s a huge amount of cash, and most of it is expected to go toward buying computing power. Training and running AI models is expensive, and Anthropic needs data centres and chips to keep up with demand.
How Does Anthropic’s IPO Compare to Others?
If Anthropic’s valuation lands around $1.4 trillion, it would be one of the largest public listings ever, but it wouldn’t be the biggest. That record currently belongs to Elon Musk’s SpaceX, which priced its own IPO at about $1.77 trillion back in June 2026.
Anthropic’s closest rival, OpenAI (the company behind ChatGPT), is reportedly aiming for its own stock market listing in 2027, a year behind Anthropic. Earlier reports suggested OpenAI’s IPO could value it at up to $1 trillion, lower than Anthropic’s expected range.

Frequently Asked Questions
Is Anthropic definitely going public this month?
As of mid-November 2026, that’s the plan, with a price expected on 18 November and trading due to start the next day. IPOs can still be delayed, so it’s worth checking a live source closer to the date.
Why do different articles give different valuation numbers for Anthropic?
It depends on which shares are counted. A basic calculation using only outstanding shares gives a lower number (around $1 trillion). A “fully diluted” calculation, which also counts employee and future share grants, gives a higher number (up to about $1.4 trillion).

Some reports mention a portion of shares being set aside for retail (everyday) investors, rather than only large institutions, though the exact details can change before the final pricing.
