Anthropic’s November IPO Could Raise $100B at $1.5T-$2T Valuation, Report Says

Anthropic is reportedly aiming to float on the stock market in the week beginning 16 November, in an offering that could raise about $100 billion and value the Claude maker at between $1.5 trillion and $2 trillion. Those figures, reported by The Wall Street Journal, would make this one of the most closely watched share sales in technology history. They are not yet terms announced by Anthropic.

What is official is that the company filed its registration statement with the US Securities and Exchange Commission on 26 October and intends to list its Class A shares on Nasdaq under the ticker ANT. Anthropic says it has not determined how many shares it will sell or set a price range. Its SEC filing is still preliminary. Until an amended prospectus supplies the missing numbers, the possible $100 billion raise, valuation and trading week remain expectations that could change.

A $100 billion share sale would be remarkable even in a market accustomed to enormous AI investments. The Associated Press reports that SpaceX raised about $86 billion in its June IPO, setting the current record. Anthropic would exceed it if the upper end of today’s reported expectations became reality. But investors should not treat the comparison as a completed result before the offer is priced and shares are allocated.

The planned listing is not just a test of enthusiasm for Claude. It asks public investors to put a price on the economics of frontier AI. Anthropic sells models and tools to businesses, developers and individual users, while the computing capacity required to train and run those models can absorb vast sums. A large IPO could give the company more room to secure chips, data centres and power, but access to capital does not by itself prove the business can eventually earn attractive returns on that spending.

The newly public prospectus offers a much firmer basis for that debate than private-market estimates. The Associated Press says Anthropic generated more than $16 billion in revenue in the first half of 2026. It also reported a net loss of about $80.7 billion for the period, including a one-off accounting charge of roughly $72.4 billion connected to financing agreements. The full net-loss figure should therefore not be mistaken for cash spent operating Claude over six months. Investors will need to examine recurring costs, margins and cash flows alongside the dramatic headline numbers.

The Wall Street Journal says Anthropic had earlier prepared for an October offering before aiming for November. Filing publicly now makes a mid-November debut possible, but not inevitable. The company still needs an effective registration statement, a final price range, investor demand and market conditions that support the transaction. The reported week of 16 November is a target rather than an official listing date.

TechBooky covered the public filing when it arrived. The new question is how much investors will pay for the growth it reveals. Earlier, our analysis of Anthropic’s reported infrastructure commitments showed why even fast-rising sales must be weighed against the cost of expanding the systems behind Claude. Those commitments stretch over multiple years and are not a single annual bill, yet they help explain why the company is pursuing such a large pool of capital.

The listing would also make Anthropic a public-market reference point for other AI labs. OpenAI and its rivals would be compared against a company whose revenue, risk factors and spending are laid out for shareholders. That transparency could sharpen the debate around whether the AI boom is creating durable businesses or demanding ever larger rounds of financing to keep pace.

For now, there are two separate headlines. Anthropic has formally filed to go public. A potentially record-breaking November IPO at a trillion-dollar-plus valuation is what sources expect, not what the company has committed to deliver. The next amended prospectus, with a share count and price range, will show how close the reported ambition is to an actual offer.
