Anthropic, the AI company behind the Claude models, has made its IPO paperwork public. On October 26 it filed a registration statement on Form S-1 with the Securities and Exchange Commission for a proposed initial public offering of Class A common stock, planned for the Nasdaq Global Select Market under the ticker “ANT.” The price range and the number of shares haven’t been set, and the registration isn’t effective yet, so nobody can buy IPO shares today.
That hasn’t stopped the questions: when it will trade, what a share might cost, whether brokers like Schwab or Fidelity will offer it, whether there’s a legitimate way in before the IPO, and whether it’s worth buying at all. This page separates what’s confirmed in the filing from what’s only reported, shows what the numbers inside the S-1 actually say, explains the unusual voting structure, and walks you through the real ways to get shares, along with the traps.
Where the IPO process stands
Filled steps are done; open steps are still ahead
Eight Quick Answers
The questions people type into search right now, answered directly. Details follow below.
It has filed to. The public S-1 went up on October 26; the IPO still depends on SEC effectiveness and market conditions.
“ANT,” on the Nasdaq Global Select Market, according to the filing.
Not announced. Media reports point to mid-to-late November.
Not set yet. The price range will appear in an amended filing before the roadshow.
Not legitimately without company approval. Anthropic says unapproved transfers are void and SPV purchases aren’t permitted.
Unknown until the deal launches. Both run IPO programs, and each has its own eligibility rules.
No, on a net basis. It reported an operating loss of $693 million and positive operating cash flow of $3.9 billion in the first half.
No. The founders’ Class F share holds 50.1% of ordinary votes, and a trust elects most of the board.
Confirmed, Reported or Unknown?
A lot of IPO coverage blends filing facts with sources and speculation. When we read the S-1 on SEC EDGAR, the offering price, share count and underwriting discount were still blank, which is normal for a first public filing. Here’s how each claim stands.
| Question | Status | What we know |
|---|---|---|
| Has Anthropic filed? | Confirmed | Public S-1 filed October 26; confidential draft submitted June 1 |
| Exchange and ticker | Confirmed | Nasdaq Global Select Market, “ANT” |
| Stock being sold | Confirmed | Class A common stock, one vote per share |
| Lead banks | Confirmed | Goldman Sachs and Morgan Stanley lead a syndicate of 20+ banks |
| Listing date | Reported | Week of Nov 16 or Thanksgiving week, per news reports |
| Amount raised | Reported | $100 billion or more, per the Wall Street Journal |
| Valuation | Reported | $1.5 trillion to $2 trillion, per news reports |
| Lock-up length | Reported | Possibly longer than the usual 180 days for some holders |
| Price range, share count | Unknown | “Not yet determined,” per Anthropic |
| Retail allocation | Unknown | Brokers will announce if they participate |
Why the timing has moved. Earlier reports had pointed to a September or October listing; later coverage said the debut was pushed to November so the company could show third-quarter results before the roadshow. Until Anthropic files an amendment with a price range, any specific date is a target, not a commitment. Big deals regularly shift by a week or two with market conditions.
The legal line you’ll see everywhere. Anthropic’s notice states that the offering “will be made only by means of a prospectus” and that shares can’t be sold, and offers to buy can’t be accepted, before the registration statement becomes effective. That’s why no legitimate broker can sell you IPO shares yet, and why anyone claiming to is a red flag.
What the S-1 Shows About the Business
The filing gives the first audited look at Anthropic’s finances. The headline numbers are extreme in both directions, so context matters.
Revenue grew several times over
Billions of dollars, as reported in the S-1
Revenue. Anthropic reported $4.585 billion in revenue for 2025 and $16.286 billion for the first six months of this year, with $11.6 billion in the second quarter alone. Fortune put first-half growth at roughly 1,300% over the same period a year earlier, driven by demand for Claude products, especially among businesses.
The giant loss, explained. The S-1 shows a net loss of $41.965 billion for 2025 and $80.748 billion for the first half of this year. Fortune reports that about $72.4 billion of the half-year figure came from an accounting charge tied to the rising value of convertible notes, a non-cash item that grows when the company’s valuation rises. The operating loss, which excludes that charge, was $693 million, narrower than $2.1 billion a year earlier. On an adjusted basis that also strips out stock compensation and some other items, Anthropic reported operating income of about $1.6 billion, roughly a 10% margin. Operating cash flow turned positive at $3.9 billion.
Compute is the biggest cost. Second-quarter compute spending was $5.6 billion, and the company says it earns about $2.08 in revenue for every compute dollar. Its future compute and infrastructure commitments total roughly $542 billion to $567 billion over the coming years, including about $120.5 billion in deals with SpaceX and $125.2 billion in five-year lease payments for its own “Anthropic Direct” data center buildout, according to Fortune’s review of the filing.
Concentration. The top five customers produced about a quarter of revenue in the first nine months of this year, and nearly half of revenue flows through cloud marketplaces run by Amazon, Google and Microsoft, which are also competitors. The filing estimates that 5% to 7% of revenue this year came from customers later found to be violating its usage policies. The company had about 5,300 employees at the end of September.

Who Controls Anthropic After the IPO
This is the part most likely to surprise buyers. Anthropic is a public benefit corporation, and its share structure gives control to the founders and an independent trust, not to people who buy stock on Nasdaq.
| Class | Who holds it | Votes | Economic rights |
|---|---|---|---|
| Class A | IPO buyers and others | One vote per share | Yes |
| Class N | Certain holders, incl. public benefit fund | None (except by law) | Yes |
| Class F | One share, Founder LLC | 50.1% of ordinary votes | No |
| Class T | One share, Long-Term Benefit Trust | Elects board majority | No |
| Class E | None outstanding at IPO | Limited matters only | No |
Three groups, three kinds of power
Simplified from the S-1’s description of capital stock
The founders’ vote. The seven cofounders, including Dario and Daniela Amodei, control a single Class F share through a Founder LLC. It carries no economic rights but casts 50.1% of the votes on matters submitted to stockholders generally, so the founders decide most ordinary votes. Fortune reports that each cofounder has pledged 80% of their personal Anthropic equity to philanthropy.
The trust’s board seats. The Long-Term Benefit Trust is meant to be five financially disinterested trustees with expertise in AI safety, national security, public policy and social enterprise. Through its single Class T share, it elects and can remove the directors who make up a majority of the board. The S-1 says it doesn’t run day-to-day management or strategy.
What that means for Class A buyers. You get economic ownership and one vote per share, but public holders can’t outvote the founders or replace the board majority. As a public benefit corporation, the board is required to weigh shareholder returns against its stated mission, and Motley Fool’s analysis notes that a trust-elected board could put safety ahead of stock returns if the two conflict. Some investors accept that trade-off; others avoid companies where they have little say. Either view is reasonable, but know which one you hold before you buy.
A 5% stake set aside. The filing describes 846,840,960 Class N shares, about 5% of fully diluted shares as of June 30, contributed to an Anthropic Public Benefit Fund subsidiary. Those shares have economic rights but no ordinary votes.
Share Price Math: What a Valuation Would Mean Per Share
“Share price prediction” is one of the most searched phrases about this IPO. We won’t predict a price; nobody outside the deal knows it yet. What we can do is show the arithmetic that turns a headline valuation into a per-share number, using the share count the S-1 implies.
Where the share count comes from. The S-1 says 846,840,960 Class N shares equal 5% of fully diluted shares as of June 30, assuming the Amazon convertible notes fully convert. That works out to roughly 16.94 billion fully diluted shares. Divide a valuation by that number and you get an implied per-share value. This is a back-of-the-envelope figure: the actual share count can change before pricing (for example, through new shares sold in the offering or a stock split), and the underwriters set the offering price from investor demand, not a formula.
Implied value per share at each valuation
Valuation ÷ ~16.94B fully diluted shares. Arithmetic only, not a price forecast
Illustration only. Not a forecast or a recommendation.
Two cautions about IPO-day math. First, if you buy on the market after the first trade, you pay the market price, which can open well above the offering price. Second, first-day moves can reverse. Use the “hypothetical move” box to see how a 20% gain or a 20% drop changes a position; that range is a reminder, not a guess.
How Individual Investors Could Get Shares
There are only a few legitimate paths, and each has trade-offs. Here they are side by side.
| Path | When | Price you pay | Catch |
|---|---|---|---|
| Broker IPO program | Before first trade | The IPO price | Only if your broker participates; allocations limited |
| Buy on Nasdaq | After first trade | Market price | Can open far above IPO price; volatile |
| Pre-IPO private shares | Now | Private terms | Anthropic says unapproved transfers are void |
| Funds claiming exposure | Now | Fund’s market price | Holdings via SPVs Anthropic doesn’t permit |
| Indirect via backers | Now | Their share prices | Small slice of much larger companies |
1. Through your broker’s IPO program
Big retail brokers sometimes get an allocation of IPO shares to offer customers. According to NerdWallet, Fidelity, Schwab, Robinhood, SoFi and E*TRADE offered shares directly in the SpaceX IPO in June. Whether any of them will offer Anthropic shares won’t be known until the deal launches. When we went through the brokers’ own IPO rules, the requirements differed in ways that matter:
Fidelity limits IPO participation to customers with at least $25,000 in eligible assets, asks qualifying questions, and takes an “indication of interest” with a 100-share minimum. You must confirm after pricing, and Fidelity says confirming doesn’t guarantee an allocation. Schwab requires an eligibility questionnaire for each offering, a minimum liquid net worth and suitable investment experience; you place a conditional offer and must affirm it by 7 a.m. Eastern the morning after pricing. Robinhood uses a random allocation, so requesting more shares doesn’t improve your odds; it holds the full buying power until allocation, doesn’t currently allow retirement or joint accounts in IPO Access, and may block you from future IPOs for 60 days if you sell within 30 days.
2. On the open market after it starts trading
Anyone with a brokerage account can buy ANT once it trades, assuming the deal completes. Hot IPOs often open above the offering price; SpaceX priced at $135 and opened around $160. If you plan to buy on day one, consider a limit order, which sets the most you’re willing to pay, rather than a market order that fills at whatever price is available in a fast-moving open.
3. Before the IPO: proceed with extreme care
In May, Anthropic warned that any sale or transfer of its stock, or any interest in it, that its board hasn’t approved “is void and will not be recognized on our books and records,” and that it doesn’t permit special purpose vehicles to buy its shares. Major marketplaces like Forge and Hiive told NerdWallet that Anthropic shares aren’t available on their platforms. Some listed funds advertise Anthropic exposure through SPVs; NerdWallet called some of those claims suspicious given the company’s stance. If you’re offered “pre-IPO Anthropic shares,” treat it as a red flag until proven otherwise.
Indirect exposure is the one pre-IPO route without those problems. Amazon, Alphabet, Nvidia, Microsoft and AMD each have investments in or major commercial ties to Anthropic, but each is a huge company, so Anthropic is a small part of what you’d be buying.

Risks the S-1 Spells Out
Fortune counted roughly 94 pages of risk factors in a filing of more than 300 pages. These are the ones most relevant to an individual buyer.
Losses are expected to continue
The company warns that rising costs and continued losses are expected as it keeps building. Revenue growth has been extraordinary, but so is spending.
Huge compute commitments
Roughly $542 billion to $567 billion in future compute and infrastructure obligations could strain cash if demand slows. The filing notes that a default could trigger cross-defaults under its credit agreement and convertible notes, and that power hookups and chip supply could be delayed.
Partners are also rivals
Amazon, Google and Microsoft supply much of its compute and carry nearly half its revenue through their cloud marketplaces, while also competing with it. The filing says they could prioritize their own compute needs.
A fight with the Pentagon
The Department of War designated Anthropic a supply chain risk after a dispute over limits on military uses of its AI. On September 25, a federal appeals court upheld the designation 2-1; Anthropic said it is considering further review. A separate district court ruling against the government in August remains in effect.
Safety and misuse
The filing discloses incidents in which its model gained unauthorized access to real outside systems during security testing, and discusses misuse, weaponization and highly autonomous systems as risks. It also flags that employee morale or departures could suffer if staff feel the company isn’t living up to its safety mission.
Limited shareholder influence
With founders holding 50.1% of ordinary votes and the trust electing the board majority, public holders can’t force changes in strategy, and the board may prioritize the company’s mission over returns.

What to Do in Your Situation
Different readers need different next steps. Find yours.
Check your broker’s IPO page and sign up for alerts now; the request window usually opens only a few days before pricing. Make sure your account type is eligible (some programs exclude retirement or joint accounts), that you meet any asset minimums, and that cash is in place, since some brokers hold the full amount until allocation. Read the preliminary prospectus when it posts.
IPO allocations for small accounts are often tiny or zero. Many brokers offer fractional shares once a stock trades, which lets you buy a dollar amount rather than whole shares. Waiting a few days or weeks after the debut lets the opening frenzy settle; there’s no rule that you must buy on day one.
Stop and verify. Anthropic says unapproved transfers are void, and it doesn’t permit SPVs. Look the seller up on FINRA BrokerCheck, never wire money to an individual, and report suspicious offers to the SEC at 1-800-732-0330 or help.sec.gov. Scams often surge around famous IPOs.
You may already have indirect exposure. A higher Anthropic valuation could raise the value of those companies’ stakes, but Anthropic is still a small part of each. Check your overall tech concentration before adding ANT on top; many index funds will already hold several of these names.
Some coverage has speculated about fast-tracked index inclusion, as happened with SpaceX and the Nasdaq-100, but nothing has been announced, and index rules differ. If it happens, index funds would buy automatically, so you’d get exposure without acting.
Read your equity agreements and the lock-up section of the final prospectus closely. Reports have said Anthropic considered a lock-up longer than the usual 180 days for some holders and possibly allowing some existing holders to sell in the offering. Taxes on newly sellable shares can be large; talk with a tax professional before selling.
That’s a personal decision this page can’t make for you. Useful questions: Would you be comfortable if it fell 30% after listing, as some recent mega-IPOs have? Are you buying the business or the excitement? Do you accept having little say in governance? How large would it be in your total portfolio? If you’re unsure, a licensed financial adviser can help you weigh it against your goals.

Bottom Line
Before you place any order
- Read the preliminary prospectus once the price range is filed, especially the risk factors and the description of capital stock.
- Confirm the final price, share count and any lock-up terms in the final prospectus.
- Decide the most you’re willing to lose, and keep the position a size you can live with.
- Use a limit order if you buy after the debut.
- Ignore anyone selling “pre-IPO” access; verify with BrokerCheck and report scams to the SEC.
- Check whether you already hold Anthropic’s backers through funds you own.
Anthropic has filed publicly to list on Nasdaq as ANT, with a debut reported for mid-to-late November. The business shows very fast revenue growth, improving operating results and positive operating cash flow, alongside enormous compute commitments, a large non-cash net loss, customer concentration, a government dispute and a governance structure that gives public holders little control. Whether that adds up to a buy depends on your goals and risk tolerance, which only you, or an adviser who knows your finances, can judge.
Questions people still ask
When is the Anthropic IPO?
No date has been announced. The public S-1 was filed October 26, and news reports point to a listing in mid-to-late November, subject to SEC review and market conditions.
What will Anthropic’s IPO share price be?
It hasn’t been set. The price range will appear in an amended filing before the roadshow, and the final price is set at pricing. As an illustration only, a $1.5 trillion valuation divided by the roughly 16.94 billion fully diluted shares the S-1 implies would be about $89 per share.
Can I buy Anthropic stock on Schwab?
Not yet. Schwab runs an IPO program with eligibility requirements, but whether it will offer Anthropic shares won’t be known until the deal launches. Once ANT trades, it can be bought through most brokers.
Where can I read the Anthropic S-1 or prospectus?
On the SEC’s EDGAR system, where Anthropic, PBC filed its Form S-1. A preliminary prospectus with a price range will follow; the lead banks, Goldman Sachs and Morgan Stanley, will also provide copies.
What is Anthropic’s valuation?
Its last private round in May valued it at $965 billion after the investment. News reports put the IPO target at $1.5 trillion to $2 trillion; the filing doesn’t state one.
Is Anthropic profitable?
Not on a net basis; it reported an $80.7 billion first-half net loss, about $72.4 billion of it a non-cash charge. Its operating loss was $693 million, and operating cash flow was a positive $3.9 billion.
Will shareholders get voting control?
No. Class A holders get one vote per share, but the founders’ Class F share holds 50.1% of ordinary votes, and the Long-Term Benefit Trust elects a majority of the board.
Does Anthropic pay a dividend?
Not today. Growth companies that are investing heavily rarely pay dividends, and the S-1’s dividend policy section is where any plans would be described.
What is a public benefit corporation?
A for-profit company whose directors must balance shareholders’ financial interests with a stated public benefit and the interests of others affected by the company’s conduct.
