Anthropic has formally filed its S-1 for a Nasdaq listing, with the ticker ANT, and Goldman Sachs and Morgan Stanley as underwriters.
The registration statement has not yet been declared effective by the SEC. After the SEC review is complete, the S-1 needs to be amended and a roadshow held. Trading can only begin once the SEC declares it effective and the offering is priced.
So the IPO will likely happen in mid-to-late November.
