AI company Anthropic files for IPO and warns of risks

The AI ​​group Anthropic is preparing its stock market debut for November. This emerges from documents that the San Francisco company filed with the Securities and Exchange Commission (SEC).

In its 333-page prospectus, Anthropic does not provide any information about how many shares will be sold and at what price. The filing of the documents paves the way for the IPO, which could take place as early as the week beginning November 16th. According to reports, the company could be valued at up to $2 trillion. The Company's shares were scheduled to be listed on the Nasdaq Global Select Market under the ticker symbol "ANT."

Anthropic will be traded on the Nasdaq

The company, best known for its AI model Claude, was co-founded by CEO Dario Amodei in 2021. Amodei had previously left OpenAI. Today, Anthropic is the biggest competitor to OpenAI, which has long been a pioneer in artificial intelligence language models with its chatbot ChatGPT.

The issue on the Nasdaq technology exchange is being led by the investment banks Goldman Sachs and Morgan Stanley. In addition to new shares from a capital increase, papers from existing shareholders should also be placed.

The exact number of shares and the targeted issue volume will be quantified in a later supplement. The official solicitation for investors is scheduled to begin in the week of November 9th. Industry circles said that Anthropic wanted to match or even exceed the volume of the previous record IPO of the space company SpaceX.

Rapid growth, but red numbers

With the stock market prospectus, the company is disclosing detailed key figures for the first time that illustrate the enormous costs in the race for top AI models. In the first six months of 2026, revenue jumped from $1.2 billion in the same period last year to $16.3 billion.

At the same time, however, the net loss increased dramatically: While there was a loss of $13 billion in the same period last year, the deficit in the first half of 2026 was around $80.7 billion - due to the high costs of building data centers for the computing infrastructure required for the progress of AI technologies.

Four types of risks

In the documents, Anthropic names four main categories of risks posed by AI: misuse, for example in the development and implementation of bioweapons or cyber attacks, loss of human control, authoritarian abuse, for example through the creation of surveillance states, and economic upheaval.

If Anthropic's AI models cause extreme damage, the company could face liability claims. These could exceed the coverage of his insurance, the documents say.

Hacker attacks by AI agents

Going public is intended to secure the company the necessary liquidity to keep up with the competition. The development of new generations of AI consumes hundreds of billions of dollars in computing power and infrastructure across the industry. At the same time, pressure on the industry is growing.

Anthropic and competitors such as OpenAI are confronted with an intensified debate about the security of autonomous systems. A series of hacker attacks by AI agents acting independently had recently raised concerns that could also weigh on the debut on the financial markets. Anthropic competitor OpenAI had therefore initially postponed its IPO.
