Rapid growth, red numbers: Anthropic discloses information for possible world record IPO

The US startup Anthropic is planning to be the first major AI rival to OpenAI to go public on the US stock exchange Nasdaq. Industry circles say that the volume could even exceed that of the previous record IPO of the space company SpaceX.

The US startup Anthropic is the first developer of highly developed top models of artificial intelligence to venture onto the stock exchange floor. The company filed a corresponding application with the US Securities and Exchange Commission (SEC). Anthropic is one of the leading AI providers in the USA and, with its AI assistant Claude, competes directly with the ChatGPT developer OpenAI as well as industry heavyweights such as Google and Microsoft. Trading activity on the Polymarket forecasting platform shows that Anthropic has a 91 percent probability of going public by November 30th.

With this step, the startup is disclosing detailed key figures for the first time that illustrate the enormous costs in the race for top 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. The business model is primarily aimed at corporate customers.

The stock market debut is planned on the New York technology exchange Nasdaq under the ticker symbol “ANT”. The company had already submitted the application documents confidentially in June. The issue 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. Polymarket shows a 58 percent chance of the company going public with a valuation between $1.5 trillion and $1.75 trillion.

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 facing 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.
