Anthropic said Thursday that it has closed a Series H financing round totaling $65 billion, producing a post-money valuation of $965 billion. The company said the capital will be allocated to safety and interpretability research, expanding compute capacity to meet demand for its Claude models, and scaling products and partnerships.
The financing was led by Altimeter Capital, Dragoneer, Greenoaks and Sequoia Capital. A group of co-leads included Capital Group, Coatue, D1 Capital Partners, GIC, ICONIQ and XN. Anthropic also named dozens of participating institutional investors across the round.
Krishna Rao, Anthropic's Chief Financial Officer, said the company’s run-rate revenue crossed $47 billion earlier this month. Anthropic added that enterprise adoption has increased among global customers since its Series G round in February.
Among the list of significant participants, Anthropic cited AMP PBC, Baillie Gifford, Blackstone, Brookfield, D.E. Shaw Ventures, DST Global, Fidelity Management & Research Company, General Catalyst, Insight Partners, Jane Street, Lightspeed Venture Partners, MGX, NTTVC, NX1 Capital, Situational Awareness LP, T. Rowe Price Associates, Inc., T. Rowe Price Investment Management, Inc., and Temasek.
Anthropic said the Series H includes $15 billion of previously committed investments from hyperscalers, with Amazon accounting for $5 billion of that amount.
Strategic infrastructure partners also took part in the funding. Anthropic listed Micron, Samsung and SK hynix among the participants it identified as strategic infrastructure partners.
In recent weeks the company has expanded compute capacity through multiple commercial agreements. Anthropic said it reached a deal with Amazon for up to five gigawatts of new capacity, and separate arrangements with Google and Broadcom for five gigawatts of next-generation TPU capacity. The company also announced access to GPU capacity on SpaceX’s Colossus 1 and Colossus 2 platforms.
Anthropic noted that Claude is available across major cloud platforms, including Amazon Web Services, Google Cloud and Microsoft Azure. The company said AWS remains its primary cloud provider and training partner.
