The Anthropic IPO filing went public on Monday, and the number that will travel fastest is an $80.7 billion net loss. Anthropic, PBC filed a Form S-1 with the Securities and Exchange Commission on October 26, 2026. The document lays out finances, risks and governance before any shares are sold, and it gives outside investors their first detailed look at the books of a leading US AI model maker.
The company has applied to list on the Nasdaq Global Select Market under the ticker ANT. It confidentially filed in June, which gave regulators time to review the financials before the public could see them. The share count and estimated price range remain blank, and the filing says its information is incomplete and may change. USA 24 has followed the filing as it moved toward public view, and the document is now out.
The timing matters. Microsoft and Alphabet report after the close this week, and investors want to know whether AI spending is still paying off. Anthropic's numbers give them a direct test case.
Anthropic IPO filing revenue: $16.29 billion in six months
Revenue for the six months ended June 30 reached $16.29 billion, up from $1.16 billion in the same period of 2025, according to TheWrap. That first-half total is more than three times the $4.59 billion Anthropic generated in all of 2025. Coverage rounds the figure differently, and some outlets report $16.3 billion.
The second quarter carried most of the progress. Revenue hit $11.6 billion, and the company posted an operating profit of $974 million for that quarter, its first, according to The Next Web. Across the full first half, the operating loss was $693 million, down from $2.135 billion a year earlier.
Customer data shows how widely the company has spread. Anthropic had more than 11,900 customers paying at least $100,000 in trailing-twelve-month revenue as of September 30, and more than 1,900 paying $1 million or more, according to Unite.ai. The filing also estimates that 5% to 7% of revenue in the nine months to September 30 came from customers that broke usage policy or terms. Investors will want to know how that share has changed over time, and the risk section is where they should look.
Why the $80.7 billion loss is mostly an accounting entry
The first-half net loss totals $80.748 billion, according to FinanceFeeds. About $72.4 billion of that comes from non-cash fair-value charges tied to convertible notes.
Convertible notes are debt that can turn into equity. Their accounting value rises when the company's own valuation climbs, and the company records that increase as a loss. The paper loss grows as the business is valued more highly, which is why the gap between the $80.7 billion net figure and the $693 million operating loss deserves attention before anyone draws conclusions.
Cash and short-term investments stood at $112.4 billion and $19.3 billion at June 30, and total capital raised to date is $141.1 billion. The filing also treats the reported value of note purchase deals with Google and Amazon as an accounting item, not cash spent. Readers comparing Anthropic with rivals should keep those two categories separate.
Anthropic compute obligations, Amazon financing and control
The filing shows roughly $417 billion in future obligations to pay providers for compute, according to CNBC. Anthropic has also ordered more capacity for delivery between 2028 and 2031. Pricing on those deals is not finalized, and they are expected to add $125 billion to $150 billion to its payment obligations.
Amazon has agreed to provide up to $15 billion in financing, available in $5 billion tranches. Each draw depends on Anthropic reaching specified compute capacity milestones. That structure ties outside money to how fast the company builds out its infrastructure, so the build-out timetable becomes a financial variable for investors to track.
Control is the other big structural point. Seven co-founders, including CEO Dario Amodei and company president Daniela Amodei, will retain 50.1% of voting power on general shareholder matters after the offering. Anthropic launched five years ago when a breakaway group of OpenAI researchers, led by Dario Amodei, worried that OpenAI, run by Sam Altman, was not on a path to develop AI safely. Public shareholders who buy in will do so in a company whose founding group controls ordinary votes.
How the Pentagon dispute shows up in the risk factors
The government risk section traces back to February 27, 2026, when President Trump directed all federal agencies to stop using Anthropic's AI technology, with a six-month phase-out period. Letters dated March 3, 2026, from the United States Department of War designated Anthropic a supply chain risk, the first such designation ever applied to an American company, according to Mayer Brown.
The fight grew out of a July 2025 contract under which Claude became the first frontier AI model approved for use on classified government networks. The Department of War asked Anthropic to waive restrictions on mass domestic surveillance and fully autonomous weapons systems in that contract. Anthropic refused.
Litigation is still moving. A 2-1 panel ruling in September upheld the Pentagon's action, and a California federal judge struck down a parallel designation in August. Anthropic has asked the full D.C. Circuit to rehear the case, according to BigGo Finance, and it has sued the Pentagon in two federal district courts. Axios first reported the lawsuit over the label.
Anthropic warned investors that ongoing issues with the Trump administration and the Department of Defense could cause “material revenue losses or business disruptions,” as CNBC reported. In a company statement quoted by Yahoo Finance, the company pointed to an “evolving and uncertain regulatory and political environment.”
Regulation is a separate risk. The filing says tighter government regulation of AI could pose a significant challenge to Anthropic’s ability to deploy its technology. It also flags possible political backlash over the company’s views on policy. USA 24 has covered the company’s position on AI safety rules in its coverage of Anthropic’s draft AI bill.
Federal contractors face the most direct effect. Pentagon and civilian-agency restrictions could touch contract work tied to Claude, and Mayer Brown’s guidance is aimed at what the designation means for government contractors.
How to buy Anthropic stock and what to do now
You cannot buy shares yet. The filing does not set a price range or share count, so there is no offering price to pay. Valuation talk is running ahead of the paperwork. Reports point to valuation hopes of $1.5 trillion to $2 trillion, and Crypto Briefing reported that a mid-November debut could value the company above $2 trillion. The filing itself does not state that timing or valuation.
For scale, NPR reported that SpaceX listed in June at around $1.8 trillion. OpenAI is also nearing a raise of about $30 billion at a $1.25 trillion valuation ahead of its own IPO, as USA 24 reported.
The underwriter count also conflicts across coverage. One source says Goldman Sachs and Morgan Stanley are among 24 underwriters, while another reports a 22-bank syndicate, according to KuCoin News. Check the filing before you rely on either number.
If you want to be ready, take these steps:
- Read the risk factors and financial statements in the S-1 on SEC EDGAR. The full document is public now.
- Watch for an amended filing that adds the share count and price range. That is the signal that pricing is getting close.
- Treat unofficial “pre-IPO” share offers as a warning sign. They are common around high-profile listings.
- Ask your brokerage how it allocates IPO shares and whether it requires an indication of interest before pricing.
The next checkpoints are concrete. Microsoft and Alphabet’s earnings this week will show how investors judge AI spending before Anthropic prices its shares. After that, watch for the amended filing, the D.C. Circuit’s response to the rehearing request and the Northern District of California case. Final pricing on the $125 billion to $150 billion in pending compute deals will also determine how large the company’s commitments become.
