Anthropic may publicly file its S-1 IPO prospectus as early as this Friday, according to Yahoo Finance, cited by IT之家, cnBeta and AIbase, which attributed the report to three unnamed people. Anthropic confidentially submitted a draft IPO registration to the SEC in June, and companies using that process must make their filing public at least 15 calendar days before the investor roadshow begins. The company did not respond to a request for comment on the timing, and cnBeta reported that a public filing would clear a procedural hurdle for a November listing while the final date still depends on market conditions. Reports citing The Wall Street Journal put first-half 2026 revenue at $16.3 billion with a net loss of more than $80 billion; AIbase and cnBeta, the latter citing the Financial Times, said Anthropic told investors third-quarter revenue reached $16.8 billion, up from $11.5 billion in the second quarter, and that it was profitable on an adjusted basis. Wall Street expects the IPO could raise up to $100 billion at a valuation of up to $2 trillion, and the offering is expected to exceed SpaceX's June IPO.
