Anthropic Raises $65 Billion, Overtakes OpenAI as World's Most Valuable AI Startup

Anthropic has raised $65 billion in a new funding round that values the AI startup at $900 billion pre-money, propelling it past OpenAI as the world's most valuable AI lab. The rise is staggering in its speed. The round was led by Altimeter Capital, Dragoneer, Greenoaks, and Sequoia Capital, and comes just three months after Anthropic raised $30 billion at a $380 billion valuation. Anthropic's annualized revenue run rate crossed $47 billion this month — a more than fivefold increase since the start of the year. The company also unveiled Claude Opus 4.8, its latest flagship model, which significantly improves on previous versions in generating code and mathematics. The financing included strategic investments from Samsung, Micron, and SK Hynix. Anthropic insiders have discussed a possible IPO later this year, though no timeline has been confirmed.
