Anthropic has opened its books, testing whether huge AI growth can become a sustainable business.

October 27, 2026 — Anthropic, the company behind the Claude AI models, has publicly filed for an initial public offering. It filed a Form S-1 with the U.S. Securities and Exchange Commission on October 26, 2026, and applied to list Class A stock on Nasdaq as ANT.

Editor's Highlight: The headline loss is not the whole story: most of the $80.7 billion net loss was a non-cash charge tied to Anthropic's rising valuation, while revenue reached $16.3 billion.

The Filing, in Plain Terms

An S-1 is the main document a company files when it plans to sell shares to the public for the first time. It sets out the business, finances, risks and terms known so far.

Several central terms are still blank. The number of shares and price range have not been set, and the registration has not yet become effective, so no shares can be sold until the SEC declares it effective.

Both Anthropic and existing shareholders will sell shares, according to Decrypt. Goldman Sachs and Morgan Stanley were named first among 24 underwriters. The filing follows a confidential draft submitted in June 2026.

Newsroom Focus: Reported valuations of $1.5 trillion to more than $2 trillion are not offering terms. The filing leaves price, share count and valuation blank.

A Loss That Needs Explaining

Anthropic reported revenue of $16.29 billion for the six months ended June 30, 2026, against $1.16 billion a year earlier. Full-year revenue was $4.59 billion in 2025, up from $386 million in 2024 and $41 million in 2023.

The net loss was $80.7 billion. Most of it was a $72.4 billion charge for changes in the fair value of convertible notes and other instruments, driven primarily by the rise in Anthropic's valuation, according to the filing.

That is a non-cash accounting adjustment, not cash spent running the business. The operating loss, a more direct measure of operating performance, was $693 million, down from $2.14 billion a year earlier, according to Tech Startups.

Growth, Customers and Cash

Anthropic was founded in 2021 by Dario Amodei and former OpenAI researchers, according to Tech Startups. Its coding assistant, Claude Code, has become a major contributor to growth, alongside its Claude models for businesses and developers.

As of September 30, 2026, it had more than 11,900 customers generating at least $100,000 in revenue over the previous 12 months. More than 1,900 generated at least $1 million, and about 250 generated at least $10 million.

Decrypt reported that Anthropic had raised $141.1 billion in total as of June 30, 2026, and held $112.4 billion in cash and equivalents, plus $19.3 billion in short-term investments. In May, it raised $65 billion at a $965 billion valuation.

• 2023 revenue: $41 million.
• 2024 revenue: $386 million.
• 2025 revenue: $4.59 billion.
• First half of 2026: $16.29 billion.

Who Will Control Anthropic?

Anthropic is a public benefit corporation. Its directors must balance shareholders' financial interests with its stated purpose: the responsible development of advanced AI for the long-term benefit of humanity.

Ordinary shareholders will have limited control. The Long-Term Benefit Trust, five financially disinterested trustees, will elect a majority of the board through a special class of stock.

Before the offering, Anthropic will issue a single Class F share to an entity owned by its seven co-founders, carrying 50.1% of voting power on most matters. The filing says that makes it a controlled company under Nasdaq rules.

Class A holders get one vote per share, but the filing warns they may effectively be unable to influence important decisions. Anthropic also gave about 847 million non-voting shares to a subsidiary for its public benefit purpose, and co-founders pledged 80% of their personal equity to philanthropic causes, according to Decrypt.

The Compute Bill and What Investors Must Weigh

Running a frontier AI company is extraordinarily expensive. Anthropic has made more than $600 billion in computing infrastructure commitments, according to Reuters, as cited by Tech Startups.

Amazon and Alphabet remain important investors and partners, and Anthropic depends on major technology partners for computing capacity and distribution. Fast Company reported that almost half of first-half revenue came through cloud marketplaces run by Amazon, Google and Microsoft, which are simultaneously suppliers, partners and competitors.

The prospectus cites risks including competition, infrastructure costs, AI safety, regulation and reliance on cloud providers, according to Tech Startups. Bloomberg noted it flagged risks to humanity, including AI attempts to resist shutdown and to conceal or manipulate information.

Measure	First half of 2026	Comparison
Revenue	$16.3 billion	$1.2 billion a year earlier
Net loss	$80.7 billion	Mostly a $72.4 billion non-cash charge
Operating loss	$693 million	$2.14 billion a year earlier

Practical Takeaway: Watch the next amendment for price and share count, and whether operating improvement continues. Fast Company reported a roadshow could begin as soon as November 9, but that is a report, not a confirmed term.

Bottom Line

Anthropic's filing shows growth far faster than its headline loss suggests, but control stays with its founders and a benefit trust. No price, share count or listing date is set yet. Watch the next filing for those terms.
