Anthropic is reportedly aiming to go public as soon as mid-November. The timing comes from Bloomberg News, October 1, 2026, which cited people familiar with the matter. Anthropic has not confirmed the November timetable in the sources reviewed.
What Anthropic has confirmed
On June 1, 2026, Anthropic announced that it had confidentially submitted a draft registration statement on Form S-1 to the SEC for a proposed initial public offering. It said this gives it the option to go public after the SEC completes its review, that the offering depends on market conditions, and that the number of shares and the price had not been set.
What Bloomberg reported
As Bloomberg reported on October 1, the people said Anthropic could begin formal marketing as soon as the week of November 9. That would put it in line to start trading before Thanksgiving on November 26. They said it is still expected to debut by the end of the year at the latest, and that the timeline could shift because deliberations are ongoing.
Bloomberg also reported that prospective investors believe a fair valuation is in the range of $1.8 trillion to $2 trillion, and that the company expects to match or beat the size of SpaceX’s IPO. These points are unconfirmed.
What is not known
Anthropic has not announced a pricing date, share count, price or valuation in the sources reviewed. The November timing, the valuation range and the size comparison are Bloomberg’s reporting from unnamed sources, and the timeline could change.
