Anthropic plans to go public in November – and presents figures

The AI ​​group Anthropic is preparing its stock market debut for November. This emerges from documents that the San Francisco company submitted to the authorities on Monday. Shares of the company would be listed on the Nasdaq Global Select Market under the ticker symbol “ANT,” it said. According to observers, it could be the largest IPO ever.

Anthropic could eclipse SpaceX's June IPO, which raised a record $86 billion. Anthropic would also go public before OpenAI.

How high the amount actually raised will be is unclear, as is the final valuation and issue price of the shares. But even with more conservative estimates, the five-year-old startup would become one of the most valuable companies in the world. For Amodei and his sister and co-founder Daniela, this could also mean an increase in assets worth billions.

The 335-page document shows Anthropic's revenue is growing rapidly; However, like many other technology companies that go public, the company is not yet in the black. The company behind the chatbot “Claude” recorded a net loss of $80.7 billion in the first half of 2026 - although 90 percent of this was due to the increased valuation of convertible bonds, for example. Because the company value has risen sharply, the calculated value of these obligations has also risen.

The company was valued at $965 billion by private investors earlier this year. The valuation could rise to $1.5 or even $2 trillion as a result of the IPO. At a valuation of $1.5 trillion, Anthropic would be one of the most valuable listed companies in the world, similar to Tesla.

What must be distinguished from this is the amount that Anthropic could actually raise with the IPO: According to reports, up to 100 billion US dollars could be raised through the sale of shares, thus surpassing the current record that SpaceX - another Elon Musk company - only set at the beginning of the year.
