Anthropic was founded in 2021 in San Francisco by former members of OpenAI, including Dario Amodei, its CEO, and his sister Daniela Amodei, the company's president. From the start, the company has made AI security the heart of its positioning. Five years later, it has become one of the largest generative AI laboratories in the world and will be the first to go public.

Its flagship product is Claude AI, a family of language models available in several ranges (Haiku, Sonnet, Opus and Fable). Unlike ChatGPT, whose notoriety is mainly based on the general public, Claude has established itself among businesses and developers. According to the press, professional customers represent approximately 80% of Anthropic's revenues and more than 1,900 companies spend at least $1 million per year, and 250 more than $10 million.

Anthropic can also count on strong support. Amazon and Google are among its main investors and will each hold more than 5% of the capital after the IPO. They are also its main suppliers of computing power. Anthropic is finally leasing computing capacity from SpaceX, to whom it will pay approximately $3.1 billion per month once all the promised capacity is delivered.

Finally, Anthropic presents a rare feature for a company of this size: it is a Public Benefit Corporation (PBC), an American status which requires it to pursue a mission of general interest in addition to the search for profit. Its official mission is the responsible development of advanced AI for the long-term benefit of humanity. This status has direct consequences for future shareholders, as we will see below.

Anthropic published its IPO prospectus (S-1) on October 26, 2026. The company is targeting a listing on the Nasdaq Global Select Market under the ticker ANT. The IPO could take place as early as November 19 or 20, 2026, while the number of shares offered and the price range have not yet been set.

On the valuation side, Anthropic raised $65 billion in May 2026 based on a valuation of $965 billion. According to Reuters, investors are now hoping for a valuation above $2 trillion in the IPO. At this level, Anthropic would become the 7th most capitalized company in the world.

Financially, Anthropic's IPO document confirms unparalleled growth for a company of this size. Anthropic achieved 16.3 billion dollars in turnover in the first half of 2026, compared to 4.6 billion for the whole of 2025. Over one year, turnover for the 2nd quarter was multiplied by around 14.
