🇺🇸Anthropic’s IPO prospectus is expected in late September, with marketing potentially beginning by mid-October.

Sources cited by Reuters said Anthropic expected to make its initial public offering prospectus public in late September. Marketing for the offering could begin as early as mid-October, but the reports did not state that either milestone had been completed.

Separate reporting said Anthropic was close to selecting Morgan Stanley and Goldman Sachs for key underwriting roles. Morgan Stanley was described as the leading candidate for the lead-left position, while Goldman Sachs was expected to serve as stabilization agent; those assignments had not been finalized.

JPMorgan, Citigroup and Barclays, which had previously provided debt financing to Anthropic, were also reported as potential participants in the underwriting group. The source material contains differing reports about the possible filing and listing timetable, so the late-September prospectus and mid-October marketing dates remain reported expectations rather than filed facts.
