Anthropic has confidentially submitted a draft S-1 registration statement to the SEC for an initial public offering, according to the earlier report, and the newer report said the Claude maker is targeting a possible October listing, though the timing remains tentative. Morgan Stanley and Goldman Sachs are leading the planned offering, with JPMorgan also participating. The IPO preparations follow Anthropic’s late-May 2026 Series H funding round, which valued the company at $965 billion on a post-money basis, and a report said its annualized revenue run rate exceeded $47 billion. The latest coverage frames the offering as a sign of the escalating financial demands of developing advanced AI models, a factor that could reshape investment strategies and broader market dynamics in the AI sector.
