Anthropic files for IPO seeking $100 billion as revenue and losses soar

Artificial intelligence startup Anthropic filed for an initial public offering on Monday, revealing massive revenue growth alongside an $80.7 billion net loss for the first half of 2026.

The San Francisco-based company plans to trade on the Nasdaq under the ticker symbol ANT. While the filing did not disclose the specific number of shares or their price, Deutsche Welle reports the IPO could occur as early as November. Analysts suggest the company could reach a valuation between $1.5 trillion and $2 trillion, a significant increase from its $965 billion valuation in May.

Financial data in the S-1 paperwork showed revenue reached approximately $16.3 billion in the first half of the year. However, expenses remain high, with the firm reporting a net loss of $80.7 billion for that same period, compared to a $13 billion loss a year prior. Despite these losses, Deutsche Welle noted the company held $112.4 billion in cash as of June 30. Euronews reported that third-quarter revenue allegedly hit $16.8 billion, though critic Gary Marcus accused the firm of omitting specific third-quarter details in the filing to hide a potential drop in demand.

In a letter to investors, Anthropic's co-founders described AI as one of history's most consequential technologies but warned it could pose existential risks to humanity if not managed with strict safeguards. The company stated it might take the unusual step of slowing development for safety reasons, even if it means losing ground to competitors. The filing also acknowledged that political engagement and safety positions could lead to increased regulatory scrutiny or public backlash.

The IPO is expected to be a major test for investor interest in the AI sector. Al Jazeera noted the debut could potentially eclipse the IPO of SpaceX. Anthropic’s move comes as its primary rival, OpenAI, also prepares for a stock market debut scheduled for next year.

Background

Founded five years ago by former members of OpenAI, Anthropic is the creator of the AI assistant Claude. The company filed confidentially with the SEC in June 2026 before making its paperwork public on Monday.
