TL;DR
Anthropic filed a preliminary registration statement for an initial public offering on Oct. 26, 2026, disclosing rapid revenue growth, an $80.7 billion net loss for the first half and substantial commitments for computing capacity. The filing also warns that its AI products could pose catastrophic or existential risks and describes governance rules that limit public shareholders’ voting power. The offering price, size and valuation are not disclosed.
Anthropic, PBC filed a preliminary registration statement for an initial public offering with the U.S. Securities and Exchange Commission on Monday, Oct. 26, disclosing fast-growing revenue, an $80.7 billion net loss in the first half of 2026 and risks that include the possibility its AI products could pose “catastrophic or existential risks to humanity.” The filing gives investors their first detailed public account of the private AI company’s finances and governance, but does not state the offering’s size, price or valuation.
The preliminary prospectus reports $16.3 billion in revenue for the six months ended June 30, 2026, compared with $1.16 billion in the same period a year earlier. Revenue was $11.6 billion in the second quarter alone. The company reported its first quarterly operating profit in Q2, at $974 million, while its operating result for the first half was a loss of $693 million. The filing leaves third-quarter revenue blank.
The reported $80.7 billion first-half net loss was largely driven by non-cash changes in the estimated fair value of convertible notes, derivatives and other financing instruments. Anthropic attributed $72.4 billion primarily to a rise in the fair value of outstanding convertible notes as its valuation increased. The company also reported $3.9 billion in positive operating cash flow and $131.7 billion in cash and short-term investments as of June 30.
The filing 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, according to the document. It also lists major agreements with Google, Amazon and Microsoft. A widely reported $542 billion total is not printed in the prospectus; it combines figures from different disclosures, including estimates and commitments that are not all the same type or necessarily additive.

What the Filing Means for Investors
The filing gives public-market investors a clearer view of a company whose business depends on both rapid AI demand and access to enormous computing capacity. Anthropic’s revenue growth is substantial, but its results also show how quickly costs, financing accounting and future infrastructure obligations can shape the financial picture. The first-half net loss is not equivalent to an $80.7 billion cash outflow: the company reported positive operating cash flow, and most of the loss came from non-cash valuation changes. Still, convertible securities can affect future share ownership when they convert.
Governance is another issue for potential buyers. Under the structure described in the filing, a trust elects a majority of the board, while a founder share carries 50.1% of the votes. Public shareholders would have one vote per share within the remaining 49.9%. That setup means an IPO would not necessarily give outside investors control over board decisions, even as the company becomes subject to public reporting.
For customers and business partners, the prospectus signals that Anthropic’s plans and financial performance will face regular public scrutiny if the offering proceeds. It also describes a strategy centered on usage-based revenue and products designed to become part of customers’ workflows. The filing does not establish how customers will respond or whether the company can sustain its recent growth and margins.

Revenue Growth and Compute Costs
Anthropic’s reported annual revenue rose from $41 million in 2023 to $386 million in 2024 and $4.59 billion in 2025. Its first-half 2026 revenue was $16.29 billion, with most coming from metered usage: $13.1 billion, compared with $3.2 billion from subscriptions. The company said roughly 28% of first-half revenue came from customers billed outside the United States.
The filing’s quarterly figures show how sharply the business expanded: revenue climbed from $376 million in the first quarter of 2025 to $11.56 billion in the second quarter of 2026. Anthropic reported that Q2 2026 revenue grew 1,368% year over year, while compute and infrastructure costs grew 300%. Those figures describe different rates of change and do not mean costs are falling in absolute terms.
Anthropic also says it secures computing capacity well in advance. It warns that capacity can arrive in large blocks and that operating margins may compress when it does. The filing’s discussion of future compute obligations draws on multiple categories: agreements signed or amended after the end of 2025, estimated additional capacity whose terms are not final, and subsequent commitments. Those amounts should not be treated as one confirmed total because their definitions differ and some may overlap.
“The change 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 Terms and Spending Totals
The filing is preliminary and does not disclose an offering price, share count, IPO size or company valuation. Reports citing valuations of $1.5 trillion to $2 trillion and describing the deal as potentially the biggest IPO are not figures established in this document. The prospectus also leaves its aggregate committed-spend figure blank in the relevant passages.
The reported $542 billion figure should be treated cautiously. It is a press calculation combining a $417 billion figure for future minimum payments under agreements signed or amended after Dec. 31, 2025, with a $125 billion low-end estimate for additional TPU capacity in 2028–31 whose terms are not final. The filing describes agreements involving leases, cloud services and data-center capacity, not simply one data-center contract. Other commitments disclosed in the filing use different definitions and may overlap.
It is also not yet clear when Anthropic will set final IPO terms, whether the proposed offering will proceed on the schedule investors may expect, or how its revenue growth and margins will develop as infrastructure commitments take effect. The prospectus’s risk disclosures identify possible harms and business challenges; they do not confirm that those outcomes have happened.
Final Terms Await SEC Review
Anthropic’s registration statement is preliminary. The company can amend it as it responds to the SEC review process and prepares the proposed offering. Investors will need later filings or an updated prospectus for any disclosed price range, share count, offering size and timing, as well as revisions to financial statements and risk factors.
Further disclosures should also clarify how the company presents its compute commitments and whether it updates estimates as contracts are finalized. Until those documents appear, the filing provides a snapshot as of its stated reporting periods—not a final account of Anthropic’s future spending, valuation or IPO terms.
