Recent reporting from early October positions Anthropic for a mid-November 2026 IPO, with formal marketing eyed for the week of November 9 and trading targeted before Thanksgiving, driving the 59% implied probability for that month. The company shifted from an earlier October window to incorporate full third-quarter financial results, including its annualized revenue run rate surpassing $65 billion by July. This timeline aligns with its confidential S-1 filing, $15 billion credit facility efforts, and a potential $2 trillion valuation amid heavy compute spending commitments and operating losses. December carries secondary odds due to possible last-minute regulatory or market adjustments before year-end.
