The Anthropic IPO moved from a confidential draft to a public filing on Oct. 26, 2026. Anthropic filed its Form S-1 registration statement with the U.S. Securities and Exchange Commission that day, Engadget reported. The company has applied to list Class A common stock on the Nasdaq Global Select Market under the symbol “ANT”.
What the Anthropic IPO filing says
Listing and offering terms
The preliminary prospectus is incomplete. The S-1 leaves the share count, the price range, and the closing date blank. It says the terms may change. Both Anthropic and selling stockholders would sell Class A shares. Anthropic would not receive any proceeds from the selling stockholders’ shares.
The cover page lists 22 underwriters. Goldman Sachs, Morgan Stanley, and J.P. Morgan appear first, followed by Citigroup, Barclays, and Wells Fargo Securities. The underwriters would hold an option to buy additional shares from Anthropic.
Anthropic said it plans to use the net proceeds for general corporate purposes. Those include working capital, operating expenses, and capital expenditures, including compute and infrastructure, plus hiring. The company said it may also use a portion of the money to cover tax withholding tied to the settlement of employee restricted stock units. It said it has no agreements for any material acquisitions.
Anthropic IPO revenue and losses
Revenue rose from $41 million in 2023 to $386 million in 2024 and $4.585 billion in 2025. For the six months ended June 30, 2026, revenue reached $16.286 billion. The same period in 2025 produced $1.163 billion, so revenue rose about 14 times year over year.
Spending rose as well. Operating expenses came to $16.979 billion in the first half of 2026. Compute and infrastructure made up $8.945 billion of that total. Sales, marketing, and partnerships cost $3.168 billion, and personnel cost $3.152 billion. The operating loss was $693 million, down from $2.135 billion a year earlier.
The net loss was far larger at $80.748 billion. Most of it came from a $72.388 billion change in the fair value of convertible notes, derivative liabilities, and simple agreements for future equity. Anthropic said the change was primarily driven by a rise in its enterprise valuation. Net loss for 2025 was $41.965 billion, including a $34.308 billion change of the same kind.
At June 30, 2026, Anthropic held $131.651 billion in cash, cash equivalents, and short-term investments. Its accumulated deficit stood at $132.902 billion. The filing says Anthropic runs Claude across AWS Trainium, Google TPUs, NVIDIA GPUs, and AMD GPUs.
How the Anthropic IPO would be governed
Anthropic is a Delaware public benefit corporation. Its Long-Term Benefit Trust is designed to have five financially disinterested trustees. Through a special class of Class T stock, the trust can elect and remove directors who would make up a majority of the board.
The seven co-founders hold a second lever. Immediately before the offering closes, Anthropic would issue one share of Class F stock to a limited liability company owned by the founders. That share carries 50.1% of the total voting power on matters put to stockholders generally. It has no economic rights.
Anthropic said it is a “controlled company” under Nasdaq rules. Class A shares carry one vote each. Class N shares carry no votes and are held primarily by strategic business partners. The filing says the trust and the founder entity together could elect every member of the board.
What the Anthropic IPO filing leaves open
The filing does not state an offering price or a valuation. Engadget reported that the offering could value Anthropic at around $2 trillion and that a debut is expected in mid-November. Those figures come from the outlet’s reporting and not from the blanks in the preliminary prospectus. An amended filing would be expected to add the price range and share count before any shares trade.
Anthropic first said in June 2026 that it had confidentially submitted a draft registration statement, according to Engadget. The October filing is the public version of that process. For background on the company’s finances, research, and rules, see the Jolt Journal’s Anthropic explainer.
Editor’s Take
The filing shows a company that is growing fast and spending nearly as fast. Revenue of $16.3 billion in six months sits against $17.0 billion in operating expenses. The $80.7 billion net loss looks alarming, but most of it is an accounting charge tied to the company’s own rising valuation. The $693 million operating loss is the cleaner gauge.
The governance setup may matter as much as the financials. Public buyers of Class A shares would get a vote. The founders and the trust would still choose the full board. Readers weighing the Anthropic IPO should wait for the amended filing with a price range and share count. This article is a summary of public filings and is not investment advice.
