Anthropic has withdrawn its preliminary initial public offering (IPO) details after identifying errors in the proposed share pricing. The withdrawn figures suggested that Anthropic could raise up to $69.3 billion through its IPO. This could make it one of the largest stock market listings in history.
On November 9, 2026, Anthropic sent bankers a draft securities filing outlining plans to sell approximately 867 million shares at $70 to $80 per share. However, the company later informed bankers that the pricing information was incorrect. It also said that an updated IPO filing would be shared at a later date.
The withdrawal has left Anthropic’s IPO valuation, share price, and fundraising target uncertain. Investors are now waiting for Anthropic to release revised IPO details ahead of its planned stock market debut. The company faces growing scrutiny over AI valuations and rising infrastructure spending.
Anthropic Withdraws $69.3 Billion IPO Filing Over Pricing Errors
Anthropic has pulled back an initial IPO filing sent to investment bankers after identifying errors in its proposed share pricing details. According to Reuters, the document outlined plans to sell approximately 866.7 million Class A shares at an estimated price of $70 to $80 per share. At the upper end of this range, the Anthropic IPO could have raised approximately $69.3 billion.
The initial filing included shares from both Anthropic and its existing investors. The company planned to issue approximately 843.3 million new shares, while existing shareholders were expected to sell around 23.3 million shares.
However, Anthropic later informed the investment bankers that the share pricing details in the document were incorrect. The company did not specify which figures contained errors or explain how the incorrect information entered the filing. It also declined to comment publicly on the withdrawal.
Anthropic said it would send an updated IPO filing at a later date. Until then, the company’s proposed share price, total offering size, and final IPO details remain unconfirmed.

Anthropic’s $26 Billion Private Placement Includes Major Tech Companies
Anthropic’s withdrawn IPO filing also revealed plans for a separate $26 billion private placement involving several major technology companies. According to Reuters, Google’s parent company, Alphabet, Nvidia, Microsoft, AMD, Broadcom, Micron Technology, and TSMC had agreed to invest in the company.
Under the proposed arrangement, these companies would purchase Anthropic’s Class N common shares at the same price offered to investors in the public IPO. The private placement was expected to close immediately after the public share offering.
The proposed investment shows Anthropic’s financial ties with some of the biggest players in the technology industry. Several of these companies also provide the computing infrastructure, chips, and other resources that support Anthropic’s AI models and services. At the same time, some are developing their own AI products and competing in the growing artificial intelligence market.
However, the $26 billion private placement was outlined in the withdrawn IPO filing. Anthropic has yet to confirm whether the investment commitments, participating companies, and proposed terms will remain unchanged in its updated filing.
Anthropic Faces Valuation Pressure Ahead of Its IPO
Anthropic’s IPO plans come as investors become more cautious about the rising costs of artificial intelligence development and infrastructure. Heavy spending on data centres, AI chips, and computing resources has raised concerns about the long-term returns on AI investments.
According to Reuters, investors had previously discussed a potential Anthropic valuation of up to $2 trillion. However, expectations later declined, with $1.5 trillion considered the upper end of the expected valuation range.
A separate report by The Washington Post on November 10 said Anthropic was targeting an IPO valuation of more than $1 trillion. The company was also reportedly planning to sell $62.5 billion worth of shares, although the final terms could change following meetings with potential investors.
This means the previously reported $69.3 billion IPO figure is not Anthropic’s confirmed fundraising target. The company has yet to release updated offering details.
Rising interest rates and concerns about AI infrastructure spending have also affected technology stocks and bonds. Several companies in the AI infrastructure and data centre sectors have delayed or withdrawn their planned stock market listings.
Anthropic Reports $17 Billion Revenue Alongside $900 Billion Computing Commitments
Anthropic has reported strong revenue growth as demand for its Claude AI models continues to increase. According to its amended filing, the company generated nearly $17 billion in revenue during the three months ended September 30, 2026. However, its quarterly growth rate slowed sharply, raising questions about whether it can maintain the same pace of expansion.
Anthropic also has nearly $900 billion in future computing commitments with infrastructure partners, including Google and Amazon. These agreements cover the computing resources needed to develop, train, and operate its AI models.
The large commitments highlight the high cost of running advanced AI services. They also raise questions about Anthropic’s future spending as it expands its AI infrastructure and competes in the growing AI market.

Anthropic Prepares for IPO as Investors Await Updated Pricing Details
Anthropic is preparing for its planned IPO, but investors are waiting for the company to release updated share pricing and offering details. According to Reuters, Anthropic was expected to begin its investor roadshow on November 10, with IPO pricing scheduled for the following week.
During the investor roadshow, Anthropic will present its business, financial results, and growth plans to potential investors before setting the final IPO terms. The IPO will also test investor demand for major AI companies.
Investors will closely examine Anthropic’s revenue growth, infrastructure costs, computing commitments, and future business prospects before deciding whether to participate in the share offering. Anthropic has not yet explained which figures in the withdrawn filing were incorrect. The final IPO share price, fundraising target, and offering details will depend on its updated disclosures.
