1. Anthropic IPO: what the public filing sets out
Anthropic has made its registration statement public, laying out plans for an initial public offering of Class A common stock on the Nasdaq Global Select Market under the ticker ANT. The S-1 filing, disclosed on October 26, reports roughly $16.3 billion of revenue for the first half of 2026 and a net loss of $80.7 billion, a result driven mostly by accounting charges.
The document is the first full look at the finances and ownership of the company behind the Claude family of AI models. A registration statement on Form S-1 is the disclosure that a US company must file with the Securities and Exchange Commission before selling shares to the public, and it normally covers the business, the risks, the audited results and the rules that will govern shareholders.
The Anthropic IPO would also be among the largest first listings of an artificial intelligence company. The Nasdaq Global Select Market, where the Class A shares are to trade, is the exchange's top tier and applies its strictest financial and liquidity standards to the companies that list there.
Anthropic is organized as a public benefit corporation, a legal form that lets directors weigh a stated public purpose alongside returns to shareholders. That status, together with an unusual voting design described below, shapes much of what the filing tells prospective buyers of the stock.
2. How large will the offering be?
The number of shares and the expected price range have not been set. Those terms are typically added in an amended filing once the company begins marketing the deal to investors, so the public document currently describes the structure of the sale rather than its size.
Both Anthropic and some of its existing shareholders will sell shares in the offering. A sale in which current holders cash out part of their stakes alongside new shares issued by the company is common for large technology listings, and it means that not every dollar raised will go to the company itself.
Goldman Sachs and Morgan Stanley are leading a syndicate of 24 underwriters. The public filing follows a confidential draft registration that Anthropic submitted in June, a route the SEC allows so that companies can have regulators review their documents before making them visible to the market.
Backers of the company are said to hope for a valuation above $2 trillion at listing. That figure is an aspiration attributed to supporters rather than a term of the offering. For comparison, Anthropic raised $65 billion in May at a valuation of $965 billion, so a listing at the level its backers hope for would roughly double the price set in that private round.
3. How fast has Anthropic's revenue grown?
Revenue for the six months ended June 30, 2026 came to about $16.3 billion, compared with about $1.16 billion in the same period a year earlier. That is an increase of roughly fourteen times in twelve months, and the half-year total is already more than three times the company's revenue for all of 2025.
The annual figures in the filing show how steep the climb has been. Anthropic reported $41 million of revenue in 2023, $386 million in 2024 and $4.59 billion in 2025. Each full year therefore brought a multiple of the previous one, and the first six months of 2026 extended the pattern at a larger scale.
The customer data points the same way. As of September 30, the company had more than 1,900 customers that each generated at least $1 million in revenue over the preceding 12 months, and about 250 customers that each generated at least $10 million. Large, recurring accounts of this kind are what investors in software and cloud businesses look for, because they suggest revenue that is spread across many buyers rather than resting on a handful.
4. Why did Anthropic book an $80.7 billion net loss?
The net loss for the first half of 2026 was $80.7 billion, but the filing indicates that the operating business was far less deep in the red. The operating loss for the period was $693 million, a small fraction of the headline loss figure and small relative to $16.3 billion of revenue.
Most of the gap comes from a charge of $72.4 billion tied to changes in the fair value of convertible notes and other financial instruments. The filing attributes the charge mainly to the increase in Anthropic's valuation. When a company's own valuation rises, the instruments that convert into its shares become more valuable to their holders, and accounting rules require that increase to be recorded as an expense on the company's books even though no cash leaves the business.
The practical consequence is that the net loss says more about the price of Anthropic's own equity than about how much the company spends to run its operations. Readers comparing the two numbers should treat the operating loss as the better indicator of day-to-day economics, while recognizing that a figure of $693 million still reflects heavy spending on training and serving AI models.
5. How much cash does Anthropic hold?
As of June 30, Anthropic reported having raised $141.1 billion in total from investors. On the same date it held $112.4 billion in cash and cash equivalents and a further $19.3 billion in short-term investments, which together amount to about $131.7 billion in liquid resources.
A balance of that size gives the company considerable room before the offering. Building and operating frontier AI systems requires very large outlays for computing capacity, and a company with this much liquidity is not forced to go public to fund the next phase of its work. The listing instead offers a public market for the shares, a currency for acquisitions and employee compensation, and an exit for early investors.
6. Who controls Anthropic after the listing?
Control will not pass to ordinary public shareholders. A single Class F share, issued to an entity owned by the company's seven co-founders, will carry 50.1% of the voting power on most matters. Because one holder group will command a majority of votes, Anthropic will qualify as a controlled company under Nasdaq rules, which allows it to rely on certain exemptions from the exchange's governance requirements.
A second layer of control sits with the Long-Term Benefit Trust. The trust consists of five trustees who are financially disinterested, meaning they hold no economic stake that would color their judgment, and it will elect a majority of the board of directors through a special class of stock. The arrangement is designed to keep the company's public benefit mission anchored even as outside investors buy in.
Holders of Class A common stock, the shares being offered, receive one vote per share. Against a single share carrying just over half of all votes on most questions, that voting power will be limited in practice.
7. What does the control structure mean for Class A investors?
The filing itself warns that the structure could largely prevent Class A holders from influencing major decisions. It specifically names a change of control as one of the areas where public shareholders may have little say, so a takeover that the co-founders and the trust do not support would be very difficult to complete.
Dual-class and special-class designs are not new in public markets, and many technology founders have retained control through them. What distinguishes Anthropic is the combination of a founder-held voting share and a trust whose board-election rights are written into the share classes, two separate mechanisms that each limit the leverage of outside buyers.
The filing also gives a sense of how the votes are divided in practice. Because the Class F share holds 50.1% of voting power on most matters, a vote that the co-founders support would pass regardless of how Class A holders cast their ballots, and a vote they oppose could not succeed without their agreement. Public holders could still sell their shares, but they could not easily change the outcome of a decision.
For investors, this arrangement is a trade. Buyers gain exposure to a company whose revenue is growing at the pace shown in the filing, but they accept that governance questions, from board composition to the possibility of a sale, will be settled largely by others.
8. What is the public benefit commitment behind the filing?
Anthropic contributed about 847 million non-voting shares to a subsidiary created for its public benefit purpose. Those shares represent 5% of the company's fully diluted shares as of June 30. The filing also discloses that the co-founders have pledged 80% of their personal equity to philanthropy.
The vehicle has drawn criticism. David Sacks, the former White House AI czar, criticized the fund, saying it remains to be seen whether it will serve the public good. His remark reflects an open question about how a block of non-voting shares held in a subsidiary will be used in practice, a point on which the filing offers a framework rather than a record of results.
9. What happens next for the Anthropic IPO?
The next visible steps are the terms that the public filing leaves blank: the number of shares to be offered and the price range. Those details will determine how much capital the offering raises and what valuation the market is asked to accept, and they will show whether the hopes of the company's backers for a valuation above $2 trillion are reflected in the pricing.
Until then, the S-1 gives investors a first complete picture. It shows a company whose revenue has multiplied several times over, whose reported loss is dominated by non-cash accounting for its own rising valuation, and whose governance is built so that its co-founders and a five-member trust, not public shareholders, hold the decisive votes.
