Anthropic Advances toward IPO with Monday Filing, Targeting Trillion-Dollar Valuation

Anthropic is set to publicly file its S-1 prospectus Monday as it races toward a potential record-breaking initial public offering at a valuation potentially exceeding $2 trillion. The artificial intelligence company closed a $65 billion Series H funding round at a $965 billion post-money valuation in May 2026, surpassing rival OpenAI to become the most valuable AI startup. With this latest funding and a mid-November IPO target, Anthropic aims to become the first company to debut at a $1 trillion-plus market capitalization, fundamentally reshaping the AI startup landscape.
