Anthropic Raises $65B, Becomes Worlds Most Valuable AI Startup

In a move that has reshuffled the global AI power rankings overnight, Anthropic — the San Francisco-based company behind the Claude AI assistant — has raised $65 billion in a Series H funding round, pushing its valuation to a staggering $965 billion. That figure places the five-year-old startup just a whisker away from the trillion-dollar mark, and — for the first time — ahead of its chief rival, OpenAI.

The announcement, made on Thursday May 28, 2026, confirms what investors have been betting on for months: that the race to build safe, enterprise-grade AI has a new front-runner.

The sheer scale of this fundraise is hard to overstate. Just three months ago, in February 2026, Anthropic closed its Series G round at a valuation of $380 billion. Thursday's announcement nearly triples that figure in a single step — a pace of growth described by analysts as unprecedented for a company of this size.
