AI giant Anthropic has overtaken rival OpenAI to become the world’s most valuable artificial intelligence startup after a blockbuster $65 billion Series H financing round which pushed the valuation to $965 billion. Anthropic’s increased validation surpassed OpenAI’s $852 billion valuation.

OpenAI’s valuation reached $730 billion in March following a massive $122 billion funding round.

Anthropic raised $65 billion in new fund-raising that put its value at $900 billion, ahead of OpenAI’s last valuation of $730 billion, as the companies duel for A.I. dominance.
