Anthropic, the artificial intelligence company behind Claude, has filed for an initial public offering (IPO) in the United States, setting the stage for what could become one of the largest stock market listings in history. The company submitted its registration statement to the US Securities and Exchange Commission (SEC) on October 26, 2026, and plans to list on the Nasdaq Global Select Market under the ticker symbol ANT.
The proposed IPO comes amid intense competition in the AI industry, with investors closely watching the growthspending and profitability of companies developing advanced AI models.
Anthropic Plans Nasdaq Listing Under ANT Ticker
Anthropic has proposed listing its Class A common stock on the Nasdaq Global Select Market. The company has appointed major investment banks, including Goldman Sachs, Morgan Stanley, JPMorgan Securities and Citigroup, to help manage the offering.
The company has not yet finalised the number of shares it intends to sell or the IPO price range. However, reports suggest the listing could take place as early as November 2026.
Anthropic was valued at approximately $965 billion following its May 2026 funding round. Market estimates suggest its public-market valuation could rise substantially, although the final figure will depend on investor demand and the terms of the offering.
Claude Maker’s IPO Could Break Fundraising Records
Anthropic’s proposed IPO could challenge the record for the largest public stock offering. Reports suggest the company could seek to raise as much as $100 billion, potentially surpassing SpaceX’s reported record offering of approximately $86 billion.
However, Anthropic has not officially confirmed its fundraising target. The final amount will depend on the number of shares offered and the price determined during the IPO process.
The listing would give public-market investors an opportunity to invest directly in the company behind Claude, one of the major competitors in the generative AI market.
Anthropic Reveals Its Proposed Share Structure
The IPO filing outlines a share structure designed to distinguish between voting and non-voting shareholders. Class A common stock would carry one vote per share, while Class N common stock would have no voting rights.
The filing also describes a proposed arrangement involving Founder LLC, through which the company’s founders would exercise voting power through a special class of shares.
Anthropic operates as a public benefit corporation, a structure that requires it to consider broader public interests alongside financial performance. Its stated mission includes developing advanced AI systems safely and distributing their benefits widely.
Legal Risks and AI Spending Remain Major Concerns
Despite its rapid expansion, Anthropic faces significant financial and legal challenges. Its filing discusses the substantial costs of developing advanced AI systems, infrastructure requirements, competition and potential legal liabilities.
The company recorded a $1.5 billion charge in September 2025 to settle a copyright dispute brought by authors over the use of their books in training AI models.
Anthropic also highlights risks associated with increasingly capable AI systems, including potential misuse and the possibility of serious harm. These disclosures are likely to attract attention from investors assessing the company’s long-term prospects.
What Anthropic’s IPO Means for the AI Industry
A public listing would represent a major milestone for Anthropic and the broader AI sector. It could provide the company with additional capital to expand computing infrastructure, develop Claude and compete with rivals such as OpenAI and Google.
At the same time, public investors will scrutinise its spending commitments, revenue growth, governance structure and ability to build a sustainable business.
The IPO could become a defining test of investor confidence in the AI industry, particularly as companies continue to invest heavily in advanced models and computing capacity. The final valuation and fundraising amount remain subject to the offering process.
