Recent reports confirm Anthropic is accelerating its IPO timeline, with plans to publicly file its S-1 registration as soon as October 23 and begin investor roadshows the week of November 9, positioning a mid-November listing before Thanksgiving as the most likely outcome. The company behind the Claude large language models reported Q3 revenue of $16.8 billion at its October 14 investor day, alongside adjusted profitability and positive free cash flow, strengthening its case after confidentially submitting a draft S-1 in June. This contrasts with OpenAI’s expected 2027 debut and reflects strong trader consensus around Anthropic’s competitive positioning in frontier AI development. Key near-term catalysts include the public S-1 release and market conditions for what could be a record-sized offering.
