Anthropic could begin marketing its IPO as soon as the week of November 9, 2026, with trading possible before Thanksgiving, according to Bloomberg. That is a reported target—not a confirmed listing date. Anthropic has confirmed a confidential filing for a proposed IPO, but has not announced final timing or terms.
When is Anthropic going public?
Bloomberg reported on October 1 that Anthropic was aiming to go public as soon as mid-November 2026. People familiar with the matter said formal IPO marketing could start as soon as the week of November 9, potentially leaving time for the shares to begin trading before Thanksgiving on November 26. Bloomberg identified Nasdaq as the expected venue. These are reported plans, not an announced transaction timetable. Bloomberg

Has Anthropic confirmed its IPO date?
No. Anthropic has said it submitted a confidential SEC filing for a proposed IPO, but its statement does not confirm the November schedule. The company said an offering would depend on market conditions and other factors, and that the number and price of shares had not been decided at the time. As Anthropic put it, “This gives us the option to go public after the SEC completes its review.” The statement was quoted by the Associated Press on June 1, 2026. Associated Press

A confidential filing is a step toward a possible offering, not confirmation that shares will be sold on a particular date. The sources do not establish a final listing date, offer price, share count, or valuation.
