SAN FRANCISCO — Artificial intelligence company Anthropic announced Thursday it raised $65 billion in private funding, pushing its valuation to $965 billion and vaulting the company past its chief rival OpenAI to become one of the world’s most valuable startups.
The funding round was led by investment firms Altimeter Capital, Dragoneer Investment Group, Greenoaks Capital, and Sequoia Capital. The company’s valuation represents a dramatic jump from approximately $380 billion just three months ago, when Anthropic closed its previous funding round.
Anthropic said it’s now generating annualized revenue of $47 billion from selling its technology to organizations using its Claude AI assistant for tasks including writing code and other professional work. The company noted that enterprise adoption has accelerated significantly since its last funding round, with customers deploying Claude across core business operations.
“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,” said Krishna Rao, Anthropic’s chief financial officer.
The investment will support safety and interpretability research, expand compute capacity to meet rising demand, and scale the products and partnerships used by enterprise customers. Strategic infrastructure partners including Micron, Samsung, and SK hynix are participating in the round to support Anthropic’s compute expansion needs.
The company also announced the launch of Claude Opus 4.8, its newest AI model, which it says offers improved performance in coding and other professional tasks.
Anthropic was founded in 2021 by former OpenAI leaders. The company, along with OpenAI and SpaceX, is expected to pursue public listings in the coming years.
