Anthropic raised $65B in Series H funding at a post-money valuation of $965B — vaulting it ahead of OpenAI ($852B) in both market value and reported revenue, and making it company one of the most valuable private startups in history.

Anthropic also launched Claude Opus 4.8, an incremental upgrade to Opus 4.7 that shows the biggest gains in terminal coding, knowledge work, and financial analysis.
