Anthropic's IPO prospectus is still not public on EDGAR, as Reuters says the autumn tech-listing calendar is down to Anthropic alone

Anthropic's IPO prospectus was still not public on the SEC's EDGAR system on 25 October. A full-text search of S-1, S-1/A, DRS and F-1 filings from 1 to 25 October found none from Anthropic. A confidential draft does not appear on EDGAR until it is made public.

Reuters reported on 22 October that Anthropic is pressing ahead with a listing planned for the middle of November and could make its prospectus public as early as late October, citing people familiar with the matter who cautioned that the dates could change. Anthropic is expected to start marketing its shares to investors in the week of 9 November, Reuters reported.

“A once-robust fall calendar for technology IPOs is down to just Anthropic,” Reuters wrote. The data-centre operator Switch and the AI infrastructure company Nscale have pushed their listing plans back to later in the year, Reuters reported, and Nscale's delay was partly driven by the need to answer comments from SEC staff. SoftBank-backed SB Energy has also postponed its listing, according to Reuters. A day later SK hynix halted its review of an IPO for its storage unit Solidigm, which the Switchboard ran on 24 October.

The Anthropic IPO is the most-covered AI storyline of the past week: the Switchboard's press count found it in 158 outlets for the week to 24 October.
