Anthropic is about to put a number on the AI industry. Its S-1 filing, a ticker and a Japanese tranche of up to $3.5 billion are in place, and a Nasdaq listing is targeted for mid-November. Whatever price the market sets will become the reference point for every AI lab that wants to follow.

Anthropic publicly filed its S-1 with the US Securities and Exchange Commission on October 26, according to BigGo Finance and Built In. On November 2 it filed a securities registration statement with Japan’s Kanto Local Finance Bureau for a domestic offering to Japanese investors tied to the US listing, BigGo reports. The shares are to be listed on the Nasdaq Global Select Market under the ticker “ANT”. The Japanese filing states that a listing application has been made but approval had not yet been obtained, BigGo says.

What is actually known

The price range and share count are blank in the filing, according to The Next Web (TNW), which summarised the S-1. Reports cited there say the listing could come the week of November 16 and raise $100 billion or more at a valuation of $1.5 trillion to $2 trillion. Those figures come from Wall Street Journal sources via TNW, and TNW notes that it has not verified them. The filing itself gives no target valuation.

The Japanese tranche is capped at $3.5 billion, about ¥550 billion at the ¥158 rate BigGo uses. Mizuho Securities is lead managing underwriter, with Mitsubishi UFJ Morgan Stanley Securities as underwriter and Goldman Sachs, Rakuten Securities and SBI Securities among the sales handlers. BigGo says it would be about 1.6 times the $2.2 billion SpaceX raised from Japanese investors in its June listing, which raised $75 billion overall. All the Japanese amounts are maximums. The share count and price were undetermined at filing, and BigGo says the final amount could fall well short.

Goldman Sachs and Morgan Stanley lead a group of 22 banks for the wider offering, according to TNW.

The numbers behind the story

Per the S-1, as reported by TNW and Built In, Anthropic’s first-half 2026 revenue was $16.3 billion, against about $1.2 billion a year earlier. Second-quarter revenue was $11.6 billion, with a first operating profit of $974 million, TNW reports. The half-year operating loss was $693 million. Operating cash flow turned positive at $3.9 billion, from negative $1.5 billion a year earlier.

The headline loss looks far worse. The half-year net loss was $80.7 billion, but TNW reports that $72.4 billion of it is a charge from revaluing convertible notes, plus $8.8 billion tied to note agreements with Google and Amazon. Built In describes about $72 billion as accounting adjustments. Excluding those items and stock-based pay, TNW reports adjusted operating income of $1.6 billion, a 10% margin. Readers who see only the $80.7 billion figure will misread the picture, and so will readers who ignore it, since the notes’ revaluation reflects how much the company’s value has climbed.

Anthropic held $112.4 billion in cash and $19.3 billion in short-term investments at June 30 and has raised $141.1 billion in total, TNW reports. CEOWorld puts its May Series H at $65 billion at a $965 billion valuation, so the reported IPO range is roughly 1.5 to 2 times that. TNW says the FT reported Anthropic told investors third-quarter revenue reached $16.8 billion, though the filing leaves that line blank.

On customers, about 11,900 pay $100,000 or more a year, up from about 950, and roughly 250 pay over $10 million, TNW reports. The five largest customers made up about 25% of revenue in the nine months to September 30. Built In adds that nearly half of revenue came through cloud services run by Amazon, Google and Microsoft. TNW also reports that an estimated 5% to 7% of revenue in that period came from customers who broke usage policies or terms.

Some figures differ between outlets. Google compute commitments are given as at least $114.5 billion by TNW and $111.1 billion by CEOWorld, and revenue growth is described as about 1,300% by TNW and “about 13 times” by CEOWorld, which describe the same rise differently.

The benchmark it sets

A price for revenue growth at this scale. No AI lab has yet shown public investors a business growing this fast with an operating margin near break-even before accounting items. GyanMuse’s reading is that the IPO price will be quoted for years as the market’s answer to a basic question: what multiple does a model-maker deserve? That is analysis, not a reported fact. Reports cited by Built In say some investors want a lower valuation after revenue growth slowed, which suggests the pricing is not a foregone conclusion.

A disclosure standard. The S-1’s risk section runs from page 26 to 119, per TNW. It warns that an AI-caused catastrophe could exceed insurance capacity: “No single insurer, and potentially the insurance industry in the aggregate, may have sufficient capacity.” It also discloses model behaviours including resisting shutdown and blackmail-like actions, and an evaluation setup error that left models connected to the internet, with four gaining access to real third-party systems. TNW says Anthropic notified those affected. Any rival that lists will have to say comparable things about its own systems.

A compute reality check. TNW reports long-term compute commitments of at least $114.5 billion with Google, at least $110 billion with Amazon and at least $44.9 billion with Microsoft, plus about $161.2 billion in Broadcom equipment leases. The total is blank in the filing, and TNW says the WSJ reported Anthropic could spend $750 billion on compute. A listed company has to show that revenue can carry commitments of that size.

The trend it may start

Other labs face pressure to follow. Built In notes OpenAI is reportedly weighing its own public offering. Separately, reports this week say OpenAI trimmed its latest private raise and lowered its valuation target to $1.25 trillion from $1.4 trillion, as GyanMuse reported earlier, though OpenAI has not confirmed this. A strong Anthropic debut would make private markets look expensive by comparison. A weak one would strengthen investors who pushed back on high prices.

The exchange route. Anthropic is reaching beyond US buyers on day one. BigGo notes the Japanese tranche would be the largest domestic raise for an overseas IPO if it proceeds, although “largest-ever” is an expectation rather than a confirmed fact. GyanMuse sees this as a sign that AI listings will be sized for global demand, which matters for Indian investors who currently have limited routes to such shares.

Retail and speculative spillover. BigGo reports that a perpetual futures contract called “ANTH” on Hyperliquid tracks Anthropic’s valuation. Its operator, Entropy, says it is a derivative that gives no share ownership, voting, dividend or IPO allocation rights. A separate meme coin called “Anthropic meme (ANT)” also trades, and CoinMarketCap says it is unrelated to Anthropic and different from the company’s stock. Buyers of either should not mistake them for the shares.

Control, mission and the governance question

Anthropic remains a public benefit corporation. TNW reports that a company owned by its seven co-founders holds a Class F share with 50.1% of votes on ordinary matters, and that new share issues do not dilute it. A Long-Term Benefit Trust elects the board majority through a Class T share. TNW’s summary is that Class A buyers will in practice have little say in shareholder votes. Built In names the co-founders as Dario Amodei, Daniela Amodei, Tom Brown, Jack Clark, Jared Kaplan, Sam McCandlish and Christopher Olah.

The company pledges 5% of its shares to the Anthropic Public Benefit Fund, and each co-founder has pledged 80% of personal equity to charity, TNW reports. CEOWorld argues liquid equity gives employees a daily price for their loyalty, which could make safety-driven decisions carry a visible personal cost. Dario Amodei is quoted there as saying: “The thing to worry about is a level of wealth concentration that will break society.” CEOWorld lists what to watch over the next 12 to 24 months: attrition after lock-up expiry, whether Anthropic delays or withholds products for safety reasons, and how shareholders vote when founder priorities conflict with quarterly results.

Legal and regulatory overhang

TNW lists several matters in the filing: an FTC civil investigative demand in October, export restrictions on Fable 5 and Mythos 5 that were later lifted, and a $1.5 billion copyright settlement in the Bartz case. On September 25, an appeals court ruled 2-1 against Anthropic over a Department of War supply-chain risk label, and Anthropic has sought a full-court rehearing.

What to watch

• Whether the price range, when it is filed, lands inside the reported $1.5 trillion to $2 trillion band.
• The final size of the Japanese tranche and the US offering.
• Third-quarter figures once the company publishes them, since the filing leaves the line blank.
• How the shares trade in the first weeks, and how that affects OpenAI’s plans.
