Recent reporting from Bloomberg and Reuters positions mid-November as the leading timeline for Anthropic's IPO, with formal marketing eyed for the week of November 9 and trading targeted before Thanksgiving, after delays from an earlier October window to incorporate Q3 financial results. Trader consensus reflected in the 60.9% implied probability for November aligns with this schedule, driven by the company's rapid revenue run-rate growth past $65 billion by mid-2026 and a leaked prospectus outlining a potential $2 trillion valuation amid surging compute costs. Competitive pressures from OpenAI and the need to demonstrate sustained large language model momentum further support the tight window, though regulatory reviews or market conditions could still shift timing.
