Anthropic's IPO Faces Skepticism Over Valuation and Insider Sales

Anthropic, the AI company known for its Claude model family, is preparing for its initial public offering (IPO) on Nasdaq under the ticker ANT. However, recent reports indicate growing skepticism regarding its high valuation, which has been adjusted from an initial $2 trillion to between $1.5 trillion and $1.6 trillion. This adjustment comes in light of slowing revenue growth and a weakening tech stock market.

Investor sentiment appears to be shifting, with prediction markets showing a 24.1% probability that Anthropic's market cap will fall between $1.5 trillion and $1.75 trillion at the close of its IPO, up from 18% a week prior. Additionally, the likelihood of the market cap being below $1.25 trillion has increased to 16.2%, reflecting concerns about the IPO's valuation and its potential impact on investor confidence.

As the IPO date approaches, market participants are closely monitoring any new disclosures regarding underwriter guidance, revenue growth figures, and regulatory developments. These factors could significantly influence market expectations and Anthropic's market cap at IPO close.

Moreover, the uncertainty surrounding the IPO's timing and financial metrics, including a reported $567 million operating loss, has contributed to a decline in confidence. Current estimates suggest a 55% chance of the IPO occurring in the week of November 16–20, with the potential for it to be the largest IPO of 2026 now viewed skeptically, at only 28%–32% probability.

Observers are advised to watch for updates from Anthropic regarding the specific date, price range, and share count for the IPO, as these elements could greatly affect market perceptions and the overall success of the offering.
