Anthropic files IPO papers for Nasdaq listing as ANT, reportedly raising up to $100 billion

Filing and listing plans

Anthropic filed its registration statement, the S-1, with the US Securities and Exchange Commission on Monday, 26 October 2026, setting out plans to list on the Nasdaq Global Select Market under the ticker ANT. The San Francisco company, maker of the Claude chatbot, is expected to debut next month according to AP, and sources cited by ANSA point to the week of 16 November, a timing that could still change. The filing leaves out the number of shares, the price range and the final valuation, so the amount raised is still unsettled. Reports cited by AP put the offering at up to $100 billion, while the Wall Street Journal, as cited by ANSA, puts total valuation at between $1.5 trillion and $2 trillion. Private investors valued Anthropic at $965 billion earlier this year, according to AP.

Losses and revenue

The filing covers the first half of 2026. Anthropic reported revenue of $16.3 billion for that period, against $1.163 billion in the first half of 2025, according to the S-1 figures Xataka reviewed. The net loss came to $80.7 billion, compared with $13 billion a year earlier, as AP reports. Xataka also notes that about $72.4 billion of the loss relates to SAFE contracts, under which investors pay in exchange for future shares. Wired reports that more than 11,900 customers spent at least $100,000 over the past twelve months, more than 1,900 spent $1 million or more, and roughly 250 spent $10 million or more. Wired prints the loss as $80.7 million, a figure the other reports do not support.

Risks and the company's framing

The prospectus lists risks ranging from access to computing capacity to intense competition from rival labs, and it warns that advanced AI could pose catastrophic or existential risks to humanity. It also flags misuse by threat actors for cyberattacks and biological weapons, use by authoritarian governments for surveillance, and the possibility that Anthropic could lose control of the models it develops. The filing points to the Trump Administration's decision to designate the company as a supply-chain risk. It further warns that its dealings with policymakers and public stances on AI regulation could bring greater scrutiny, adverse political reactions or disproportionate regulatory measures. The company also told investors it will make investments that may seem irresponsibly large at first glance.

“In order to fully capture the opportunity in front of us, we need to invest more aggressively than would a business that operates in a more slowly changing technological regime.”

Context and next steps

The listing would follow the SpaceX offering in June, which raised $86 billion according to AP, and would put Anthropic ahead of OpenAI, which TechRadar reports will likely debut early next year. Anthropic announced plans to go public in June 2026, and Xataka reports it submitted a confidential draft to the SEC on 1 June. TechRadar describes the Claude Mythos model as too dangerous for public release, and under Project Glasswing select countries have access to it to hunt for flaws in critical services and infrastructure. Once listed, Anthropic will have to give investors greater visibility into its finances, including whether it is profitable. The share count and price range have not been set, and Anthropic says those details will be announced later.
