Recent reporting from Bloomberg and Reuters shows Anthropic delaying its IPO timeline from October to target November 2026, with formal marketing eyed for the week of November 9 ahead of Thanksgiving. This shift, driven by the need for complete third-quarter financials after the confidential S-1 filing and strong revenue growth to a $65 billion+ annualized run rate, underpins the 62.3% market-implied probability for November. The AI lab behind the Claude large language models projects a potential $2 trillion valuation and over $100 billion raise, positioning it as a major test of public appetite for frontier AI despite substantial 2025 losses and compute commitments. Key near-term catalysts include any public prospectus updates or roadshow announcements that could lock in the window.
