Anthropic has withdrawn the pricing details of its stock market debut after telling bankers it planned to raise as much as $69.3bn (£53bn), only to claim the figures were inaccurate.

The Claude developer circulated a securities filing on Monday outlining plans to sell approximately 867 million shares at between $70 and $80 apiece, Reuters reported. A second email followed quickly, stating the pricing information was incorrect and that an updated filing would follow.

Anthropic did not specify which figures were inaccurate and declined to comment.

The original filing showed the company planned to sell around 843 million shares, with existing shareholders offering a further 23 million. At the $70-$80 range, the total offering of roughly 867 million shares implies proceeds approaching $69.3bn.

The filing also outlined $26bn in investment commitments from technology giants including Google, Nvidia, Microsoft, AMD, Broadcom, Micron and TSMC, which would participate in a private placement alongside the IPO.

The reversal comes as Anthropic prepares to begin marketing its shares to investors as soon as Tuesday, with pricing expected the following week.

Why does the retraction matter now?

The uncertainty follows last week's sharp sell-off in technology stocks, which wiped approximately $2.5 trillion from the Nasdaq amid growing concerns over AI spending and valuations. For context, that paper loss is roughly 36 times the $69.3bn Anthropic aims to raise.

Anthropic had previously been expected to seek a valuation of around $1.5 trillion, although some investors have pushed for a lower figure following the market turmoil.

Lawrence Mills, analyst at Trade Nation, said: "The $1.5 trillion valuation seems toppy and maybe needs to be adjusted lower to attract potential investors."

Morningstar has estimated Anthropic's fair value at approximately $1.7 trillion, with forecasts ranging from $500bn to $3 trillion depending on the pace of AI adoption. The research house said reaching its most optimistic valuation would require annual revenue growth of more than 60 per cent over the next five years.

What do the numbers say about the business?

Anthropic reported almost $17bn in revenue for the September quarter — annualised, that implies a run-rate near $68bn — although its sequential growth slowed and it returned to an operating loss.

The company has also disclosed nearly $900bn in future computing commitments, more than ten times its annualised revenue run-rate, raising questions about the cost of sustaining its rapid expansion.

Its listing is expected to provide a major test of investor appetite for AI companies following weeks of volatility across the technology sector.
