Anthropic Secures $65 Billion Series H at $965 Billion Valuation
Anthropic has closed a $65 billion Series H funding round at a $965 billion post-money valuation, the company announced May 28. The raise lands weeks after Claude's annualized revenue crossed $47 billion, a sign of how quickly the AI lab has moved from research outfit to enterprise backbone.
Who Backed the Round
Altimeter Capital, Dragoneer, Greenoaks, and Sequoia Capital led the investment. Capital Group, Coatue, D1 Capital Partners, GIC, ICONIQ, and XN co-led alongside them. The broader investor list includes Blackstone, Temasek, Fidelity Management and Research Company, General Catalyst, Lightspeed Venture Partners, Jane Street, and roughly a dozen additional institutions.
About $15 billion of that total came from previously committed hyperscaler investments, with Amazon contributing $5 billion. Micron, Samsung, and SK hynix also joined as strategic infrastructure partners, supplying the memory, storage, and logic chips that high-volume AI inference requires.
Compute Agreements Signed Ahead of Close
Anthropic moved quickly on capacity in the weeks before this round closed. The company secured agreements with Amazon covering up to five gigawatts of new compute, locked in five gigawatts of next-generation TPU capacity through a deal with Google and Broadcom, and gained access to GPU resources across SpaceX's Colossus 1 and Colossus 2 facilities.
Claude is now available on all three of the world's largest cloud platforms: Amazon Web Services, Google Cloud, and Microsoft Azure. AWS remains Anthropic's primary cloud and training partner.
Where the Funding Is Directed
Anthropic said the funds will go toward safety and interpretability research, expanded compute, and product development. CFO Krishna Rao pointed to Claude Code and Cowork as the products receiving priority attention. "This funding will help us serve the historic demand we are experiencing, stay at the research frontier, and bring Claude to more of the places where work happens," Rao said.
The Anthropic Series H funding closes roughly three months after the company's Series G in February 2026, a period in which run-rate revenue jumped to $47 billion. That pace suggests the commercial trajectory behind this valuation is still building, not leveling off.
At $965 billion, Anthropic sits just below the trillion-dollar threshold that only a handful of public companies have reached. Whether the next round crosses that line depends on whether Claude's adoption holds at this rate. Read the full announcement on the Anthropic Series H funding page.
