TL;DR
Anthropic filed a preliminary registration statement for a proposed public offering on October 26, 2026, disclosing rapid revenue growth, large infrastructure obligations and risks tied to its AI systems. The filing does not state an offering price or size, and it warns that the technology could pose “catastrophic or existential risks to humanity.”
Anthropic filed a preliminary registration statement for a proposed initial public offering with the U.S. Securities and Exchange Commission on Monday, disclosing fast-growing revenue, extensive computing commitments and a warning that its products could “pose catastrophic or existential risks to humanity.” The filing provides investors with the company’s financial and governance details, but does not disclose the offering’s size or share price.
The filing reports $16.3 billion in revenue for the first half of 2026, compared with $1.16 billion in the same period a year earlier. Second-quarter revenue was $11.6 billion. Anthropic reported a first quarterly operating profit of $974 million in Q2, while recording a net loss of $80.7 billion for the six-month period.
That loss largely reflects non-cash accounting changes, rather than operating cash outflow: $72.4 billion came from changes in the fair value of convertible notes, derivatives and other instruments, primarily as Anthropic’s valuation rose. The company reported $3.9 billion in positive operating cash flow and $131.7 billion in cash and short-term investments at June 30, according to the filing.
Anthropic also disclosed substantial commitments tied to computing capacity. Its non-cancelable purchase commitments rose from $54.6 billion at the end of 2025 to about $265.6 billion on June 30, 2026. The company reported additional obligations signed after that date. The filing leaves a total aggregate committed-spend figure blank, so the widely reported $542 billion figure is not a total stated in the registration statement.
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
USD, as filed. Q3 2026 is left blank in the preliminary prospectus.
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).
Where the $80.7 billion loss comes from
First half of 2026. Operating cash flow was positive: +$3.9B.

Risks Behind Anthropic’s Public Debut
The filing gives public-market investors a detailed view of a company whose growth depends on both customer demand and access to enormous amounts of computing capacity. Anthropic reported that consumption-based services generated $13.1 billion of first-half revenue, with subscriptions contributing $3.2 billion. That mix makes revenue closely linked to how much customers use the company’s products.
The disclosures also matter to businesses that rely on Anthropic’s services. A public company faces regular financial reporting and market scrutiny, while the filing describes a strategy and infrastructure base built around large, long-term commitments. Those commitments can shape capacity and costs even if customer demand or technology changes. Anthropic cautions that computing resources are purchased 12 to 18 months in advance and says operating margins may compress when major capacity blocks become available.
The technology warning is a separate investor risk from the financial figures. Anthropic’s filing says its products could pose catastrophic or existential risks; that language is the company’s disclosed assessment, not evidence that such an outcome has occurred. Its inclusion makes safety and potential harms part of the information investors are being asked to weigh alongside revenue, governance and expenses.

Revenue, Losses and Control
The filing traces revenue from $41 million in 2023 to $386 million in 2024 and $4.59 billion in 2025. It reports $16.29 billion for the first half of 2026. The company says second-quarter revenue grew 1,368% year over year, while compute and infrastructure costs rose 300%. These reported rates describe different measures; they do not establish that the growth pattern will continue.
Anthropic’s net loss figures are heavily affected by changes in the value of financing instruments. The company attributed most of its first-half loss to fair-value accounting, including the rising value of convertible notes. The filing’s operating figures offer a different view: Anthropic reported a $693 million operating loss for the first half, followed by a $974 million operating profit in the second quarter. It also cautioned that margins could fluctuate as computing capacity comes online.
The proposed listing would not give ordinary shareholders control of the company. According to the filing, a trust elects a majority of the board, while a single founder share carries 50.1% of voting power. Public shareholders would have one vote per share within the remaining 49.9%. The filing is preliminary: reported estimates of a $1.5 trillion to $2 trillion valuation and claims that the deal could be the biggest IPO ever are not offering terms disclosed in the document.
Offering Terms and Spending Totals
The preliminary filing does not specify the offering price, share count or total size, and it leaves the aggregate committed-spend figure blank. The $542 billion cited in some coverage is a press calculation from separate figures and estimates; it is not printed as a total in the filing. Those underlying categories differ and may overlap, so adding them into one confirmed obligation would be misleading.
Some of the capacity cited by the company is also not fully contracted. Anthropic estimates $125 billion to $150 billion for additional TPU capacity in 2028 through 2031, but says the terms are not final. The filing does not establish what the eventual IPO valuation will be or how investors will respond to the company’s financial and governance structure.
It also remains unclear how long the recent revenue growth and second-quarter operating profit can be sustained. The filing gives historical results and warns that margins may compress; it does not provide a guarantee of future performance. The potential effects of the company’s AI risks are likewise described as risks, not as confirmed harms.
Next Steps in the IPO Process
The registration statement is preliminary, and the offering’s price and size remain unknown. As the IPO process develops, investors will be able to assess any updated filings and final terms against the company’s disclosed revenue, losses, cash position, computing commitments and voting structure.
Further disclosures may clarify the amount and timing of infrastructure obligations, including commitments made after June 30, as well as the assumptions behind future capacity estimates. Until those details and final offering terms are public, reported valuations and spending totals should be treated as estimates or calculations rather than confirmed figures from the filing.

Why did Anthropic report an $80.7 billion half-year net loss?
The company attributed $72.4 billion of the loss mainly to changes in the fair value of convertible notes and related instruments as its valuation rose. Anthropic also reported $3.9 billion in positive operating cash flow for the first half.

No. The preliminary filing does not state the offering price, share count or total offering size. Valuation figures reported elsewhere are not terms disclosed in the filing.
What does Anthropic’s technology warning say?
The filing warns that Anthropic’s products could “pose catastrophic or existential risks to humanity.” This is a stated risk in the prospectus, not a claim that such an outcome has occurred.
