Anthropic Withdraws IPO Pricing Details From Banks After Nearly $70 Billion Plan Circulates
Anthropic, the artificial intelligence company behind the Claude chatbot, sent investment bankers a copy of a securities filing late Monday that showed plans to sell about 867 million shares at $70 to $80 each — a range that would have raised as much as $69.3 billion — and then withdrew the pricing details hours later, telling recipients the figures were inaccurate.
The unusual reversal, reported by Reuters from emails it reviewed, has left one of the most anticipated stock market debuts of the year without a confirmed price, size, or timetable just as its investor roadshow was expected to begin. Anthropic declined to comment, and the company has not explained what was wrong with the numbers it circulated.
What the circulated filing showed
According to Reuters, a representative of Anthropic sent bankers a copy of a securities filing that laid out a sale of about 866.7 million Class A shares, including a secondary offering. Anthropic itself would have sold about 843.3 million shares, while existing shareholders would have sold an additional 23.3 million shares.
At the top of the $70 to $80 range, the offering would have raised $69.3 billion. At the bottom of the range, the same share count would have raised about $60.7 billion.
The filing also showed that Anthropic had lined up $26 billion in investments from some of the world’s biggest technology companies alongside the IPO, Reuters reported.
Then came a second email. It told the same recipients that the pricing details were inaccurate and that an updated filing would follow later. The message did not specify what was wrong, and Reuters said it could not determine which details were incorrect. Bloomberg Law, citing Reuters, reported that the retracted document was an updated prospectus sent by Anthropic’s outside counsel in Canada, according to The Information.
What is confirmed — and what is not
The episode is a reminder that the numbers at the center of this story describe a draft its own author disowned, not a deal.
Confirmed: Anthropic sent bankers a copy of an IPO filing, and a follow-up email retracted the pricing details as inaccurate, with a promise to update the filing later. Confirmed as circulated, but called inaccurate: the share count of about 867 million, the $70 to $80 price range, and the implied proceeds of up to $69.3 billion.
Not confirmed: the final offering price, the final size of the sale, and whether the share count, the price range, or both were wrong. Anthropic has not said when the corrected filing will arrive, and it declined to comment to Reuters.
The distinction matters. The $69.3 billion figure comes from simple multiplication of the circulated inputs — 867 million shares at $80 each — and Anthropic itself told recipients not to rely on it. It should not be described as a finalized fundraising total.
A listing that was supposed to move fast
The confusion arrives at a delicate moment. Anthropic publicly filed its Form S-1 with the U.S. Securities and Exchange Commission on October 26, applying to list its Class A common stock on the Nasdaq Global Select Market under the ticker ANT. An amended filing followed on November 2. The deal is being handled by 22 underwriters led by Goldman Sachs and Morgan Stanley.
Because of SEC procedures for companies that filed confidentially first, the investor roadshow could not begin before November 10 — today. Reuters reported that Anthropic was expected to formally launch the roadshow on Tuesday, with pricing expected in the following week.
The Wall Street Journal reported on Monday that Anthropic still intended to pursue a listing later this month, aiming to debut as soon as Thursday or Friday, November 19 or 20, and to disclose its price range in a filing early this week. The Journal also reported that some large investors were pushing for a valuation below the roughly $1.5 trillion discussed last week, after a sharp selloff in AI stocks on Thursday. Bloomberg has separately reported potential valuations of roughly $1.1 trillion to $1.3 trillion.
Anthropic’s amended filing on November 2 disclosed third-quarter revenue of $16.96 billion, up approximately 47% from the preceding quarter, according to reports on the filing. The company’s last confirmed valuation was $965 billion, set in a private funding round in May 2026.

Why this matters
Anthropic’s listing is the biggest test yet of investor appetite for pure-play AI companies. Unlike the chipmakers and cloud providers that have carried the AI trade, Anthropic sells the models themselves, and its debut will help set a market price for the leading AI labs — including OpenAI, which is reported to be leaning toward an IPO in 2027. Scrutiny is rising across the sector: Nvidia’s board is investigating its chief executive, and Meta has introduced AI age checks for teenagers on Instagram.
The retraction also lands as Wall Street is reassessing AI valuations. AI stocks sold off sharply last week before rebounding on Monday, when the Dow Jones Industrial Average jumped 1,104 points in its best day since April as oil prices plunged. Investors are now asking harder questions about the cost of building AI systems and how quickly that spending turns into profit — the same questions Reuters’ market briefing raised on Tuesday morning.
For prospective shareholders, the consequence is delay and uncertainty. Until Anthropic files a corrected prospectus, there is no reliable price range, share count, or deal size — and the roadshow, if it begins this week, will market a listing whose basic terms are still unsettled.
Latest developments
As of Tuesday morning, no corrected filing had been made public, and Anthropic had not commented beyond the email to bankers.
What to watch next: whether Anthropic files an updated prospectus this week, what price range it discloses, and whether the roadshow begins on schedule. The company is also expected to confirm its debut date — reported to be as soon as November 19 or 20 — once the corrected terms are set.
Frequently asked questions
How much was Anthropic planning to raise in its IPO?
The circulated filing implied up to $69.3 billion at the top of a $70 to $80 range, based on about 867 million shares. Anthropic later called those details inaccurate, so the figure is not a confirmed total, and the final offering size remains unsettled.
What is Anthropic’s stock ticker?
Anthropic has applied to list its Class A common stock on the Nasdaq Global Select Market under the ticker ANT, according to its S-1 filing. The stock does not trade yet, and no shares can be bought through a brokerage until the deal is priced and the listing takes effect.
When will Anthropic go public?
No debut date has been confirmed by the company. The Wall Street Journal has reported that Anthropic is aiming to debut as soon as November 19 or 20, with the investor roadshow expected to begin this week. The timetable depends on when the company files a corrected prospectus with the final terms.
Why did Anthropic retract the pricing details?
Anthropic told bankers in a follow-up email that the pricing details were inaccurate and said it would update the filing later. It did not specify what was wrong, declined to comment, and Reuters said it could not determine which details were incorrect.
What happens next
Anthropic’s IPO remains on track in the sense that the company has not withdrawn the offering itself — only the pricing details it circulated. But the episode has introduced an avoidable wobble into one of the year’s most closely watched listings. The next filing will tell investors whether this was a paperwork error or a sign that the deal’s terms are still being negotiated. Until then, the only numbers anyone can rely on are the ones in the public S-1 — and those leave the price, the share count, and the date blank.
