Anthropic’s confidential S-1 filing in June 2026 and rapid revenue ramp to a $65 billion annualized run rate by July have fueled trader consensus around a blockbuster IPO expected in fall 2026. The company’s $965 billion Series H valuation from May, combined with surging enterprise demand for its Claude large language models and competitive positioning in frontier AI, supports market-implied odds exceeding 80% for a closing market cap above $1.8 trillion. Secondary trading and banker discussions point to potential pricing at $1.5–2 trillion or higher, mirroring recent AI listings like SpaceX, while the low probability assigned to missing a 2027 IPO reflects the advanced regulatory and underwriting process now underway. Public prospectus details expected after Labor Day and roadshow feedback remain key near-term catalysts.
