Artificial intelligence company Anthropic, the developer of the Claude chatbot, has filed for an initial public offering in the United States, revealing rapid revenue growth alongside significant financial risks as it prepares to enter the stock market.
The company submitted its registration statement to the U.S. Securities and Exchange Commission on Monday, October 26, and plans to list its Class A shares on the Nasdaq Global Select Market under the ticker symbol ANT. The filing does not yet disclose the number of shares to be sold or the offering price.
Anthropic reported revenue of 16.3 billion dollars for the first six months of 2026, compared with 1.16 billion dollars during the same period last year, representing an increase of more than fourteenfold.
However, the company also recorded a net loss of 80.7 billion dollars. According to its filing, approximately 72.4 billion dollars of that figure resulted from accounting adjustments linked to the changing value of its financing arrangements, rather than direct operating expenditure.
Its operating loss stood at 693 million dollars, significantly lower than the 2.1 billion dollars recorded in the first half of 2025. Despite the improvement, the company acknowledged that it has yet to achieve sustained profitability.
The financial disclosures highlight the challenges facing AI developers as they invest heavily in computing infrastructure, advanced chips and data centres to meet rising demand. Anthropic has entered into major infrastructure agreements with technology companies, including Amazon and Google, creating substantial long-term financial commitments.
Founded in 2021 by former OpenAI researchers, including chief executive Dario Amodei, Anthropic has expanded its presence in the artificial intelligence market through Claude, which businesses use for software development, research, data analysis and other tasks.
The proposed listing could become one of the largest public offerings in history. Some reports have placed the company’s potential valuation at between 1.5 trillion and 2 trillion dollars, although Anthropic has not confirmed a final valuation.
The IPO will give investors an opportunity to assess whether the company’s exceptional revenue growth can translate into sustainable profits, particularly as competition intensifies and the cost of developing advanced AI systems continues to rise.
Anthropic’s filing therefore places the financial sustainability of the artificial intelligence boom under closer scrutiny, with investors weighing the industry’s commercial potential against its enormous infrastructure costs and uncertain path to profitability.
