Anthropic announced a $65 billion Series H funding round led by Altimeter Capital, Dragoneer, Greenoaks, and Sequoia Capital, valuing the AI company at $965 billion post-money. The raise follows strong enterprise adoption of Claude across industries, with run-rate revenue reaching $47 billion. Global enterprises deploy Claude in core operations, while individual users increasingly rely on it for everyday work.

The funding will fuel safety and interpretability research, expand compute infrastructure, and scale products and partnerships. Strategic infrastructure partners Micron, Samsung, and SK hynix join the round, providing critical memory, storage, and logic chip technologies. Recent compute expansions include five gigawatt agreements with Amazon, Google/Broadcom TPU capacity, and SpaceX GPU access through Colossus facilities.

Claude now runs on all three major cloud platforms—Amazon Web Services, Google Cloud, and Microsoft Azure—with AWS serving as the primary cloud provider and training partner. Enterprise customers use Claude to handle complex workflows, enabling the system to learn actual business processes, context, and judgment patterns across organizations.

At $965 billion, Anthropic joins an exclusive tier of technology companies valued above $900 billion, reflecting intense investor confidence in generative AI's enterprise transformation potential and the company's position as a leader in frontier model development.
