- Anthropic is reportedly set to publish its S-1 registration statement at 9 a.m. EST, a crucial step toward a potential $100 billion-plus IPO.
- The filing will give investors the first comprehensive look at the AI startup's finances, including its rapid revenue growth and massive computing costs.
- The offering, which could value the company at around $2 trillion, is being closely watched as a bellwether for the AI sector.
A High-Stakes Debut
Anthropic is poised to release its S-1 registration statement with the SEC at 9 a.m. EST, according to a Fox Business (FOXA) report, marking a major milestone in what could become one of the largest initial public offerings in history. The filing would provide the first detailed financial disclosures from the San Francisco-based artificial intelligence company, which has astonished investors with its explosive growth.
The timing, however, remains unverified. As of early Friday, the company had not confirmed the release, and the report could not be independently corroborated. Still, the move would follow weeks of frenzied speculation and behind-the-scenes preparations. Anthropic disclosed sharply higher revenue to prospective investors on October 14, and the Wall Street Journal (NWSA) reported details from a draft prospectus on October 20. Publication of the S-1 would give investors a fuller basis for assessing the company’s finances, ownership structure, and risks—though it would not mean shares have begun trading.
Revenue Surge, Losses Mount
Anthropic’s revenue has skyrocketed. In the first half of 2026, the company generated $16.3 billion, nearly fifteen times the $1.1 billion it reported a year earlier, according to investor presentations reviewed by reporters. The third quarter alone brought in $16.8 billion, up about 45% from the prior quarter and exceeding the entire first half’s total.
Yet the company also reported a net loss of $80.7 billion for the first half, including roughly $72 billion in financing-related accounting losses. Management said the company was profitable in the third quarter on an adjusted basis, though that is not equivalent to bottom-line net profitability. Bankers have discussed raising more than $100 billion at a valuation around $2 trillion, though these figures are not final.
Risks and Regulatory Hurdles
The prospectus is expected to highlight both the promise and the perils of Anthropic’s business model. The Wall Street Journal reported that the company’s customer base is narrow and its access to computing capacity uncertain, raising questions about revenue durability and supplier dependence. Anthropic has also committed to potential computing spending of $750 billion, including deals still under negotiation—obligations that investors will need to parse carefully.
The offering has drawn political attention. New York City Comptroller Mark Levine, who oversees public pension funds with more than $325 billion in assets, urged Anthropic to pause the IPO until it addresses AI-safety and governance concerns. In an October 14 letter, Levine argued that the Trump administration’s AI-safety accord was insufficient and requested specific disclosures about audits and controls.
Anthropic, founded in 2021 by former OpenAI employees, operates as a public benefit corporation. On October 18, it announced a proposed Public Benefit Fund that would allocate 5% of its shares, subject to stockholder approval, to public-benefit causes. The company did not respond to a request for comment on the S-1 timing.
The filing would be a test of investor appetite for frontier AI at sky-high valuations. A successful offering could fuel further investment in the sector and provide Anthropic with capital to expand its computing infrastructure. A weak reception, however, could chill sentiment toward AI stocks and expose the gap between long-term infrastructure commitments and uncertain future revenue. For now, all eyes are on 9 a.m. EST.
Correction: An earlier version of this article misstated the date of Anthropic’s investor presentation. It was October 14, not October 15.
