Anthropic Could Begin Marketing Its IPO the Week of Nov. 9

Anthropic, an artificial intelligence company, has submitted its S-1 filing with the Securities and Exchange Commission (SEC) for an upcoming initial public offering (IPO). Although the exact IPO date remains undisclosed, estimates indicate that marketing for the stock will commence during the week of November 9, with the stock debut following about a week later.

Goldman Sachs and Morgan Stanley are set to handle the IPO process. The marketing efforts will encompass a promotion of the stock to institutional investors and significant buyers by Anthropic's team. The prospectus filing reveals that the company amassed $16.3 billion in sales during the first half of 2026, a stark contrast to the $1.2 billion reported for the same period last year.

However, the net loss surged to $80.7 billion from approximately $13 billion during the same period. Notably, the IPO listing price, number of shares offered in the initial tranche, and outstanding shares post-IPO are undisclosed, leaving unclear the valuation Anthropic aims to achieve and the desired funding amount. Analysts predict that the IPO could be a major event for the stock market, potentially setting a valuation lower than the previously anticipated $2 trillion.

Recent estimates suggest the company's valuation could hover closer to $1.5 trillion. While Anthropic's IPO may not match SpaceX's record-breaking $85.7 billion raised and $1.77 trillion valuation, the company's stock performance could still significantly impact the AI sector and the overall market.
