Anthropic raises $65B at a record $965B valuation, passing OpenAI

Anthropic confirmed a $65 billion Series H that values the company at $965 billion post-money, edging past OpenAI's approximately $852 billion mark and making it, on paper, the most valuable private AI lab in the world. The round drew Sequoia, Coatue and ICONIQ alongside a major Amazon cloud commitment that reports place at up to $100B, deepening the AWS-Anthropic alliance. Some accounts attribute the valuation surge to Claude Code, whose run-rate revenue is claimed to have crossed tens of billions — figures that originate partly from vendor-blog reporting and should be treated cautiously.

Mechanically, the raise positions Anthropic to fund frontier training runs, its expanding enterprise platform, and a possible public release of its Mythos-class cybersecurity model teased for within weeks. Amazon's role as both strategic investor and primary compute provider gives the deal an unusual structure: much of the capital effectively cycles back into AWS infrastructure, a pattern increasingly common across the compute-investment deals defining this AI cycle.

Competitively, the milestone reframes the OpenAI-Anthropic rivalry. OpenAI is itself reportedly racing toward an IPO and launched a $4B Deployment Company, while Anthropic leans on its coding-tool moat. The $965B figure invites skepticism — it reflects a private round, not a public market, and rests on aggressive revenue multiples.

What to watch: whether the Mythos release lands on schedule, how much of the Amazon commitment is compute-credits versus cash, and whether OpenAI responds with its own raise or accelerated IPO timeline. The valuation crown is symbolic for now, but it shifts the narrative of who leads the frontier-model race heading into the second half of 2026.
