Anthropic Raises $65B Series H at $965B Valuation, $47B Run-Rate Revenue

Anthropic announced a $65B Series H at a $965B post-money valuation on May 28, only months after its February Series G. The company disclosed that run-rate revenue crossed $47B earlier in May, with KPMG rolling Claude to 276,000 employees as a flagship enterprise reference.

The raise extends a pattern of frontier labs hitting near-trillion valuations on revenue that, while large, is still a fraction of the equity number. Anthropic positions the capital as fuel for inference compute, agentic-product investment, and enterprise go-to-market — areas where it is now directly competing with OpenAI's enterprise motion and the new DeployCo subsidiary.

Hacker News debate (276 pts, 280 comments) split between bubble skepticism and acknowledgement that the KPMG deployment, combined with the AWS native-Claude-Platform launch the same day, shows Anthropic is winning real enterprise pipeline, not just hype. Simon Willison flagged April 2026 as the month both OpenAI and Anthropic found enterprise product-market fit.

What to watch: how the $47B run-rate translates to GAAP revenue at year-end, whether the AWS-hosted Claude Platform accelerates the burn-vs-revenue curve, and whether the valuation gap to OpenAI continues to compress.
