Anthropic’s confidential S-1 filing in June 2026 and its May Series H round at a $965 billion post-money valuation anchor trader expectations for an IPO closing market cap above $600 billion. Explosive revenue growth—from roughly $9 billion annualized run rate at the end of 2025 to over $65 billion by July—driven by enterprise adoption of its Claude large language models and agentic coding tools like Claude Code has reinforced this consensus. Recent capability advances, including the September 1 release of Claude Fable 5.1 and Mythos 5.1 with leading benchmark scores, further support competitive positioning ahead of a potential fall 2026 listing. Key upcoming catalysts include the public prospectus reveal after Labor Day and marketing expected to begin in mid-October, though sustained margins and broader market conditions remain variables that could still influence final pricing.
