Anthropic, the San Francisco company behind the Claude AI assistant, made its case for a public listing on Monday by releasing paperwork for a Nasdaq debut under the ticker ANT. The step puts the five-year-old firm on course for an initial public offering that reports say could arrive as soon as November, with analysts estimating a valuation of $1.5 trillion to $2 trillion. That range would rank the sale among the largest ever seen. The company left the number of shares and the offer price unspecified in the filing with the U.S. Securities and Exchange Commission. Goldman Sachs and Morgan Stanley will serve as lead underwriters.
- Key Point: Anthropic moved from a confidential June submission to a public SEC filing on Monday, clearing the way for a Nasdaq listing under ANT; the share count and price remain blank.
- Key Point: Reports point to a possible November start, proceeds of as much as $100 billion and a valuation of $1.5 trillion to $2 trillion, which would exceed the $86 billion record held by Elon Musk’s SpaceX.
- Key Point: The seven co-founders, among them Dario and Daniela Amodei, who are siblings, wrote to prospective investors about AI’s importance and repeated warnings that Anthropic may choose to slow development even if rivals move ahead.
- Key Point: The filing shows rapid revenue growth without profitability: a $80.7 billion net loss for January to June 2026, versus $13 billion a year earlier, alongside $112.4 billion in cash and near-cash holdings on June 30.
A startup born from an OpenAI breakaway
Anthropic was established in 2021 by people who left OpenAI, the maker of ChatGPT. Its filing follows a confidential review by the SEC, which allowed the regulator to examine the company’s financial record before the details became public on Monday. The seven founders used a letter to potential shareholders to frame the listing as more than a fundraising event. They also returned to a subject the company has raised before: the social dangers tied to advanced AI. Anthropic warned that its leaders might need to make unconventional choices to reduce the speed of development, even when that allows competitors to gain an advantage.
“We believe AI is one of the most consequential technologies in human history.”
The company said the money from an IPO could give it substantial resources to speed up expansion. Its debut would follow the listing of SpaceX, and it comes as OpenAI, its main rival, is also expected to go public next year. Both offerings are unfolding against rising anxiety about AI and the competition to build AI infrastructure, including data centres with enormous energy demands. The broader mood around the technology is mixed: AI is heavily promoted, often feared and sometimes viewed as overhyped.
Growth, losses and a record-setting target
The document portrays a business expanding quickly but still lacking a profit, a pattern shared by other AI companies. For the first six months of 2026, Anthropic recorded a net loss of $80.7 billion, far above the $13 billion shortfall in the same period of the prior year. Even so, it reported $112.4 billion in cash and near-cash holdings on June 30. Reports suggest the IPO could raise up to $100 billion. That would beat the $86 billion that Elon Musk’s SpaceX ultimately collected in what remains the largest IPO on record.
The numbers put two stories side by side. On one side is demand and scale: the company behind Claude has grown fast, and a successful listing would hand it more capital to compete in a costly sector. On the other is the cost of that expansion. Anthropic has not yet turned a profit, and its losses have widened sharply. Investors will have to weigh the promise of revenue growth against the company’s spending and the possibility that returns may take time to arrive.
The signal for the AI trade
Because the filing leaves the price and share count open, the final shape of the deal will be settled later. The reported valuation and proceeds are estimates, not terms fixed in the paperwork. That leaves the market to judge how much appetite exists for a loss-making AI leader at a moment of public unease about the technology. The presence of Goldman Sachs and Morgan Stanley as lead underwriters gives the transaction a conventional Wall Street spine, but the outcome will be watched far beyond the banks.
A strong debut would be read as support for the wider AI trade and for the infrastructure spending that surrounds it. A weak one would raise questions about valuations across the sector. Anthropic’s own message adds a tension: it asks investors to back a company that says it may deliberately slow the pace of development for safety reasons. That stance may reassure some shareholders and unsettle others. The listing is therefore a test of more than one company’s accounts. It is a test of whether public markets will pay a premium for growth, safety rhetoric and heavy losses at the same time. The result will shape expectations for OpenAI’s planned debut and for the chipmakers, data-centre builders and other suppliers tied to AI demand. Alex Berry edited the report.
