TL;DR
Anthropic filed a preliminary IPO registration statement with the SEC on Oct. 26, 2026, disclosing fast-growing revenue, substantial compute commitments and warnings that its AI products could pose catastrophic or existential risks. The filing does not disclose the offering size, share price or a final valuation; widely reported figures for those remain unconfirmed by the document.
Anthropic, PBC filed a preliminary registration statement for an initial public offering with the U.S. Securities and Exchange Commission on Monday, Oct. 26, bringing the AI developer’s finances, governance structure and risk disclosures into a public filing. The prospectus reports $16.3 billion in revenue in the first half of 2026 and an $80.7 billion net loss, most of which the company attributes to non-cash valuation changes on financing instruments; it also warns that its products could pose catastrophic or existential risks to humanity.
The filing records revenue of $4.585 billion in 2025, up from $386 million in 2024, followed by $16.286 billion in the first six months of 2026. Quarterly revenue rose from $4.73 billion in the first quarter of 2026 to $11.56 billion in the second quarter. The prospectus leaves the third-quarter revenue field blank. Most first-half revenue came from metered usage: $13.1 billion, compared with $3.2 billion from subscriptions.
Anthropic reported a $974 million operating profit in Q2 2026, but a $66.31 billion net loss for that quarter. For the first half, it reported an operating loss of $693 million and a net loss of $80.75 billion. The filing says $72.4 billion of the half-year net loss came from changes in the fair value of convertible notes, derivatives and other financing instruments, primarily reflecting a higher company valuation. Operating cash flow was positive at $3.9 billion for the period, and the company reported $131.7 billion in cash and short-term investments as of June 30.
The document describes large and growing obligations for computing capacity. Non-cancelable purchase commitments rose from $54.6 billion at the end of 2025 to about $265.6 billion on June 30, 2026. It also describes obligations signed after that date. A widely circulated $542 billion figure is not printed as a total in the prospectus: the filing’s aggregate-commitment field is blank, and the underlying figures cover differently defined categories that may overlap.
Anthropic's IPO filing, the numbers
From $376 million to $11.6 billion a quarter
Six quarters of revenue, the shrinking compute share, and why a company with a first operating profit reports an $80.7 billion loss.
Revenue per quarter

Compute and infrastructure, % of revenue
Revenue grew faster than the committed compute bill.
Anthropic expects margins to “compress” again when large blocks of new compute come online (p. 134).

Public Investors Face AI and Governance Risks
The filing gives prospective investors and business customers a detailed view of the economics behind one of the most prominent AI developers. Revenue growth is rapid, and the company reported a quarterly operating profit, but the accounts also show heavy dependence on computing capacity, large contractual commitments and results that can move sharply with the valuation of financing instruments. The headline net loss is not equivalent to an $80.7 billion cash outflow, but the associated instruments can affect future share ownership through conversion and dilution.
Anthropic’s governance arrangements also matter to anyone considering the stock. According to the prospectus, a trust elects a majority of the board, while a founder share carries 50.1% of voting power. Public shareholders would have one vote per share within the remaining voting power. The filing’s warning about potential catastrophic or existential harms puts the company’s stated product risks alongside its financial and governance disclosures, rather than treating them as a separate issue.
For companies buying Anthropic services, public-company reporting may provide recurring financial disclosures, but the filing also describes a strategy that seeks to make its products difficult to leave. Large advance commitments and dependence on continued computing supply could affect the company’s ability to expand and the commercial conditions facing customers. The prospectus does not establish how those factors will play out.

What the Preliminary Filing Discloses
This is a preliminary registration statement, not a completed IPO announcement. The source report, by Thorsten Meyer of ThorstenMeyerAI.com, says the filing was placed on the SEC’s EDGAR system on Oct. 26 and cites figures from its prospectus. The document reports historical financial results and describes risks; those figures do not guarantee future performance.
The company’s reported operating performance has changed quickly. The filing says compute and infrastructure costs fell from 251% of revenue in the first quarter of 2025 to 48% in the second quarter of 2026. Anthropic also reports a 10% adjusted operating margin for the first half of 2026, a non-GAAP measure that excludes specified items, including stock-based compensation and a $1.5 billion copyright settlement. The filing cautions that margins may compress as computing capacity comes online.
Headlines about a $542 billion compute bill combine numbers reported in different parts of the filing and in press accounts. The $417 billion figure cited in the source report relates to future minimum payments under multiple agreements signed or amended after Dec. 31, 2025; it is not described as one data-center contract. A separate $125 billion to $150 billion estimate concerns additional TPU capacity for 2028 to 2031, with terms not final. Those figures should not be treated as a single confirmed total of finalized spending.
“The change in fair value was “primarily driven by an increase in the fair value of our outstanding convertible promissory notes resulting from an increase in our enterprise valuation.””

IPO Price and Compute Total Remain Open
The preliminary filing does not state the number of shares to be offered, the share price or the size of the offering. Valuation ranges of $1.5 trillion to $2 trillion and descriptions of the IPO as potentially the largest ever are reported estimates, not disclosures confirmed in the filing.
The final amount and timing of computing obligations are also not settled by the figures presented. The filing leaves its aggregate committed-spend total blank; some capacity estimates concern agreements whose terms are not final, and different commitment categories may overlap. It is not yet clear what final terms Anthropic will disclose, whether the offering will proceed on the reported timetable or how investors would value the company.
The prospectus also describes risk, not a prediction that catastrophic harm will occur. Its warning does not specify that such an outcome is certain, nor does the material provided establish how regulators, customers or investors will respond to it.
Watch for Final Offering Terms
The next public milestones would be an amended registration statement and, if the IPO proceeds, the eventual disclosure of offering size, share price and timing. Those details are not included in the preliminary filing described here. Investors and other readers can also watch for updated financial results and revisions to the company’s account of computing commitments and AI-related risks.
Until those disclosures appear, reported valuation targets and combined compute-spending totals should be treated as estimates or calculations by outside observers, not final terms established by the prospectus. The filing’s figures describe Anthropic’s position at specified dates, including June 30, 2026, and may change in later disclosures.
