Anthropic files for public listing in potential record AI offering

Artificial intelligence company Anthropic has filed paperwork for an initial public offering that could become one of the largest stock-market debuts ever, according to documents submitted to US regulators and reports cited by DW. The San Francisco-based company plans to list on the Nasdaq under the symbol “ANT”. Its filing with the Securities and Exchange Commission does not yet state how many shares it intends to sell or the proposed price, so the size of the offering remains unresolved.

Reports cited by DW said the flotation could take place as early as November and potentially raise as much as $100 billion. Analysts have placed Anthropic’s possible valuation between $1.5 trillion and $2 trillion. If the reported fundraising target were reached, it would exceed the current record, which DW attributed to Elon Musk’s SpaceX after an offering that raised $86 billion.

Anthropic filed confidentially with the SEC in June, giving the regulator time to review its financial information before the paperwork became public. Goldman Sachs and Morgan Stanley are serving as lead underwriters. The company was founded in 2021 by former OpenAI employees, including siblings Dario and Daniela Amodei.

Its principal product is Claude, a chatbot that competes with OpenAI’s ChatGPT. OpenAI is also expected to pursue a stock-market listing next year, placing the two leading AI companies on parallel paths toward public ownership. Anthropic’s filing highlights the scale of the financial race surrounding advanced AI.

The company reported rapid revenue growth but has not yet become profitable. DW reported a net loss of $80.7 billion in the first half of 2026, compared with a loss of $13 billion in the same period a year earlier, while the company said it held $112.4 billion in cash and cash equivalents as of June 30. The supplied reports do not provide revenue figures or explain the reported increase in losses.

They do show that Anthropic is seeking public-market capital while spending heavily on expansion and AI infrastructure, including the data centres required to run increasingly capable systems. In a letter to prospective investors, Anthropic’s seven co-founders said they considered AI one of the most consequential technologies in human history. They also addressed potential social risks, saying the company’s leadership might have to make unusual decisions to slow development even if that meant falling behind competitors.

The filing comes amid growing concern about the energy demands of AI data centres and the intensity of competition to build the infrastructure needed for future systems. Until Anthropic discloses the offering’s size and price, the record-breaking projections remain estimates rather than confirmed terms.
