Unconfirmed: Social-media posts are circulating claims that Anthropic briefly sent banks detailed terms for a multibillion-dollar IPO and then retracted them; Automatica Press has not confirmed the existence of any filing or withdrawal.
On 10 November, the X account @Pirat_Nation told followers that "Anthropic’s $70 billion IPO plans leaked to banks then the filing was pulled back," citing what it described as a Reuters report, and characterizing the alleged deal as one of "the biggest IPOs in history".@Pirat_Nation on X1 Automatica has not located or reviewed any such Reuters story and cannot verify that description.
In the same post, @Pirat_Nation wrote that, according to this purported filing, Anthropic "briefly sent banks details" for an offering to "raise up to $69.3 billion by selling around 867 million shares at $70–$80 each." The post also claimed the document "revealed another $26 billion in investments from tech giants including Nvidia, Google, Microsoft, AMD, Broadcom, Micron and TSMC," and that "shortly after sending the documents, Anthropic told banks the pricing details were inaccurate and that an updated filing would follow," adding that "[t]he company hasn’t explained exactly what was wrong and declined to comment."@Pirat_Nation on X1
A separate X account, @wallstengine, posted earlier the same day that "Anthropic RETRACTED the IPO details it sent to banks on Monday, telling them the figures were inaccurate and that it will update its filing with new numbers."@wallstengine on X2 In the same message, @wallstengine wrote in a "Note" that "[t]he leaked filing had shown a price range of $70 to $80 a share and a raise of up to $69.3B."@wallstengine on X2 The post did not attach any document or identify a bank or regulatory venue.
Neither account provided screenshots of a filing, a term sheet, or correspondence from Anthropic or any underwriter. Both posts describe the figures as having appeared in a document sent "to banks" and then retracted, but do not specify jurisdictions, an exchange, or a filing number.@Pirat_Nation on X1@wallstengine on X2 Automatica has not viewed any primary documents underlying those claims.
Automatica’s earlier coverage has described other unconfirmed claims around Anthropic’s capital plans, including a reported IPO-related live-stream event featuring JPMorgan Chase CEO Jamie Dimon that a financial outlet attributed to unnamed sources; Anthropic did not confirm that report at the time.Automatica Press (earlier coverage)3 That prior story, like the current posts about alleged IPO terms, rests on secondhand descriptions of documents or plans that have not been published.
What would confirm or disprove the new rumour is a verifiable regulatory filing or bank communication showing the described price range, size and investor commitments, or an on-the-record statement from Anthropic or a named underwriter addressing whether any such document was circulated and then amended or withdrawn. As of the time of writing, neither Anthropic nor any bank named in the social posts has issued a statement in the materials Automatica has reviewed.
Given the absence of primary documents or official comment, the claims by @Pirat_Nation and @wallstengine remain uncorroborated descriptions of alleged internal deal terms rather than evidence that any specific IPO structure is agreed or pending.
