Anthropic IPO at $70–$78: 2026 Listing Explained

Anthropic has put a price on its IPO: $70 to $78 per share. The company behind Claude filed Amendment No. 2 to its S-1 on November 10, 2026, launching its roadshow with 825 million Class A shares on offer and a listing on the Nasdaq Global Select Market under the ticker ANT. At the top of the range, the deal would raise about $64.35 billion and value Anthropic at roughly $1.405 trillion on a fully diluted basis — one of the largest public listings in history. First trading is expected on November 19, according to press reports, though the company has not confirmed that date.

This is a follow-up to our breakdown of the roadshow start and the amended S-1 — what follows is what changed once the price range went public.

The official terms, at a glance

The first 24 hours produced two versions of this story — here are the real numbers.

Late on November 9, a draft of the pricing terms was sent to banks showing roughly 867 million shares at $70 to $80, which would have raised up to about $69.3 billion. Within hours, Anthropic emailed to say the pricing details in that draft were inaccurate. The next day, the official amendment landed with the smaller share count and the narrower $70 to $78 range. Ignore any source still citing 867 million shares or an $80 top end — those numbers come from the retracted draft. The filed terms are broken down in detail by Invezz’s coverage of the $70–$78 range, and our earlier piece on the original S-1 filing and Claude’s pricing has the background on how Anthropic got to the roadshow.

The split inside the 825 million matters too. Anthropic itself is selling 801,351,354 new shares, and existing holders are selling 23,648,646 shares. About 97% is fresh capital going into the company; only about 3% is early holders cashing out. Anthropic gets none of the money from the shares sold by existing holders — that cash goes to those sellers.

The underwriting group is led by Goldman Sachs and Morgan Stanley, with 22 banks in total. The underwriters also hold a 30-day option to buy up to 123.75 million additional shares — the standard overallotment option, equal to exactly 15% of the offering.

Then there is the valuation, which comes in two flavors. On a non-diluted basis — using the 13.09 billion shares that will be outstanding after the offering — the company is worth about $1.02 trillion at the top of the range. On a fully diluted basis, which counts stock options, restricted units, and other shares that could exist in the future, the valuation reaches about $1.405 trillion. The $1 trillion figure in most headlines is the non-diluted one; $1.4 trillion is the fully diluted version.

What $70, $74, and $78 actually buy you

The midpoint is $74. Here is what the deal raises at each point:

• At $70 per share: 825 million shares × $70 = about $57.75 billion raised.
• At $74 per share: 825 million shares × $74 = about $61.05 billion raised.
• At $78 per share: 825 million shares × $78 = about $64.35 billion raised.

The gap between the bottom and the top of the range is roughly $6.6 billion — real money even by the standards of a deal this size.

Now, what does $1,000 buy at each price? IPOs do not sell fractional shares to retail buyers, so you buy whole shares and keep the change:

• At $70: $1,000 buys 14 shares for $980, with $20 left over.
• At $74: $1,000 buys 13 shares for $962, with $38 left over.
• At $78: $1,000 buys 12 shares for $936, with $64 left over.

The valuation math works the same way. Using the 13.09 billion shares outstanding after the offering, the non-diluted valuation is about $916 billion at $70, about $969 billion at $74, and about $1.02 trillion at $78. The fully diluted valuation, which implies roughly 18 billion shares once everything is counted, runs from about $1.26 trillion at $70 to about $1.405 trillion at $78. So pricing at the top versus the bottom swings the paper valuation by roughly $100 billion.

The practical takeaway: the final price is set the night before trading begins, and it will be one number, not a range. If you are planning an order size, plan it at $78 and be pleasantly surprised if it comes in lower. And the IPO price is a starting point, not a promise: the stock can open above or below it on day one.

The $26 billion side deal with Google, Nvidia, and the chipmakers

Alongside the IPO is a separate $26 billion private placement, priced at the IPO price and closing right after the offering. The buyers are a who’s who of the AI supply chain: Google is putting in $10 billion, Nvidia is putting in $10 billion, AMD is putting in about $2.5 billion, and Broadcom, Micron, and Microsoft are each putting in about $1 billion, with TSMC adding about $500 million.

Added to the $64.35 billion maximum IPO raise, the combined total reaches up to about $90.4 billion — a huge investment from the very companies that supply Anthropic’s chips and cloud capacity.

Reddit user rudolf_de_Leeuw wrote on r/stocks on November 10: “The part I find most interesting is the $26B placement at the IPO price to AMD, Broadcom, Google, Micron, Microsoft, Nvidia and TSMC with no lock up, since several of those are also its chip suppliers or cloud partners” — as quoted in this breakdown of the offering.

The detail that matters most in that quote is the lock-up — or rather, the lack of one. The private-placement shares are non-voting Class N stock, and they are explicitly not subject to the lock-up that will keep other shareholders from selling for a set period after the IPO. In plain English: Google, Nvidia, and the rest can sell whenever they choose, while IPO buyers and insiders face selling restrictions. They may never sell, but the freedom to sell is there, and the filing discloses it openly.

At the IPO price, the $26 billion placement buys roughly 371 million shares at $70, or roughly 333 million at $78 — all non-voting Class N stock, with no say in company decisions.

Retail investors get an unusually big slice

In most big IPOs, retail buyers get 5 to 10% of the shares. Anthropic is breaking that pattern. The filing says retail investors in the US and other countries are expected to receive up to 20% of the Class A shares offered, though the final allocation will depend on demand.

For comparison: Arm allocated about 10% of its 2023 IPO to retail, Reddit about 8%, and Instacart up to 5%. On an 825-million-share offering, 20% works out to as many as 165 million shares for retail buyers — worth about $12.2 billion at the $74 midpoint.

But “up to 20%” is not a guarantee. If your broker is participating, you request shares through its IPO platform before pricing. Your broker passes total demand to the underwriters, who decide how many shares each broker — and each customer — receives. If demand exceeds supply, requests get cut back, sometimes sharply: asking for 100 shares might get you 20, or 10, or none. The filing is careful to say the final allocation depends on demand, and in a deal this heavily watched, demand is likely to be very heavy indeed.

The brokers named in connection with the offering include Schwab, Fidelity, Robinhood, SoFi, ETrade, and Trade-PMR. The minimums vary, so check your own broker’s rules. Fidelity requires $25,000 in assets and a 100-share minimum — at $70 to $78, that means committing roughly $7,000 to $7,800 at a minimum. Robinhood, SoFi, and ETrade have no minimum, so smaller investors can request shares there. JPMorgan is leading US retail sales, and Citi is coordinating the international side.

A few honest warnings before you rush to place a request. First, getting shares at the IPO price is not the same as making money: plenty of high-profile IPOs have traded below their offer price. Second, many brokers restrict flipping IPO shares immediately, so read the fine print before you commit. Third, if you miss out, you can still buy on the open market once trading starts — at whatever the market price is that morning.

Buying ANT buys you almost no say

Here is the part that surprises most people. The 825 million shares being sold to the public carry only about 5.5% of all the votes — barely one-twentieth of the voting power.

The reason is the share structure. Anthropic’s seven founders hold 61.3% of the votes, and the co-founders alone keep 50.1% of the voting power — an outright majority, held by the people who started the company. Class A shares do carry one vote each — but the founders’ shares carry far more votes per share, and a large block sits with a trust. The arithmetic works out so that the 825 million public shares, while equal to about 11.1% of the Class A shares outstanding, translate into only about 5.5% of total voting power.

In plain English: buying ANT buys a piece of the economics, not a voice in running the company. You cannot vote out the board or block a strategy change. The founders can — that is by design, and the filing says so openly.

Founders keeping control after an IPO is a familiar tech pattern. But the scale here is striking: a 61.3% voting block held by seven people in a soon-to-be trillion-dollar company. If governance matters to you, sit with that number before you buy; if it doesn’t, that’s a legitimate choice too. Either way, go in with your eyes open.

The numbers behind the trillion

A trillion-dollar valuation invites a simple question: what is the business actually doing? For the nine months ended September 30, 2026, Anthropic reported revenue of $33.242 billion — up from $2.5 billion in the same period a year earlier. That is more than thirteen times the year-earlier figure.

The third quarter alone brought in $16.96 billion in revenue, up 47% on the second quarter. That implies second-quarter revenue of roughly $11.5 billion — a $5.4 billion jump in a single quarter.

But the costs are just as striking. Compute and infrastructure expenses for the nine-month period were $18.808 billion — more than half of total revenue, and the single biggest line in the business. Training and running frontier models takes enormous, expensive computing power. This is why the $26 billion placement matters: the companies Anthropic pays the most are now also its investors.

None of this says whether the valuation is fair. Thirteenfold revenue growth can justify a large valuation; spending more than half of revenue on computing can squeeze margins if growth slows or compute prices rise. The honest read: a very fast-growing, very expensive-to-run business, and the market will spend the next several quarters deciding what that combination is worth.

What changes for Claude users: nothing

If you use Claude — free or paid, for writing, coding, research, or anything else — here is the short version: nothing changes. Anthropic has announced no changes to Claude plans, prices, or usage limits in connection with the IPO. Your subscription costs the same, and your limits work the same way.

Big corporate events often come with quiet product changes, but none are announced here. The IPO changes who owns Anthropic, not what Claude costs or how it works.

The risks the filing doesn’t hide

Every IPO filing contains a risk section, and most of them read like boilerplate. Anthropic’s does not. The filing is blunt about the dangers of the technology itself, warning that AI systems could, without proper safeguards, “pose catastrophic or existential risks to humanity.”

The filing also says Anthropic has “met” the AI research and development threshold in its own safety policy, “based on what we expect from future models.” In other words, by the company’s own internal measure, its models have crossed a capability line that triggers additional safety obligations. The company is saying, in its own words, that its technology is powerful enough to require special safeguards — and that it believes it has them. How much comfort you take from that depends on how much you trust its own assessment of its own systems.

What happens next

Pricing is expected on November 18, with first trading on November 19 — but those dates come from CNBC reports citing people familiar with the plans, not from the filing itself, and the company has not confirmed them. The registration is not yet effective. Treat November 18 and 19 as the expected timetable, not a promise.

There is already one sign that demand is running hot. On November 11, the Australian Financial Review reported that bankers were already weighing a price above the range after heavy demand. That is a press report, not a company statement — but it fits a deal whose order book is filling fast. If the final price does land above $78, the raise and the valuation both move up with it, and the $64.35 billion figure becomes a floor rather than a ceiling.

One last note: nothing in this article is investment advice. If you are considering buying shares, do your own research, read the filing, understand the voting structure and the lock-up terms, and consider speaking with a licensed financial adviser.

Frequently Asked Questions

When does Anthropic start trading?

First trading is expected November 19, 2026, on Nasdaq under the ticker ANT, with pricing expected November 18. Both dates come from CNBC reports citing people familiar with the plans, not from the filing, and the registration is not yet effective.

What is the Anthropic IPO price range?

The official range is $70 to $78 per share for 825 million Class A shares. At the top of the range, the deal raises about $64.35 billion and values Anthropic at about $1.02 trillion on a non-diluted basis, or about $1.405 trillion fully diluted.

How can retail investors buy Anthropic IPO shares?

Retail investors in the US and other countries are expected to receive up to 20% of the Class A shares offered — far above the typical 5 to 10% — though the final allocation depends on demand. Participating brokers include Schwab, Fidelity, Robinhood, SoFi, ETrade, and Trade-PMR. Fidelity requires $25,000 in assets and a 100-share minimum; Robinhood, SoFi, and ETrade have no minimum. Request shares through your broker before pricing; if demand exceeds supply, your allocation may be cut back.

Do Anthropic IPO shares come with voting rights?

Technically yes, but practically almost none. Each Class A share carries one vote, yet the 825 million public shares together hold only about 5.5% of all votes. The seven founders hold 61.3% of the votes, and the co-founders alone keep 50.1% — a majority. The $26 billion placement is in non-voting Class N stock.

How much money is Anthropic raising in total?

The IPO itself raises up to about $64.35 billion at the top of the $70 to $78 range. Combined with the separate $26 billion private placement from Google, Nvidia, AMD, Broadcom, Micron, Microsoft, and TSMC — which closes right after the offering at the IPO price — the total reaches up to about $90.4 billion. The underwriters’ 30-day option on 123.75 million more shares could push it higher still.
