Anthropic is now the most valuable artificial intelligence company in Silicon Valley.
The AI giant announced a $65 billion Series H financing at a $965 billion valuation on Thursday. The financing puts its value above rival AI lab OpenAI.
CNBC reported in late April that Anthropic was in talks to raise capital.
The newest round was led by Altimeter Capital, Dragoneer, Greenoaks, and Sequoia Capital, and almost triples its valuation from February, when it was worth $380 billion.
OpenAI was valued atĀ $852 billionĀ in late March after closing a record-breaking $122 billion funding round.
Anthropic’s revenue has exploded thanks to its popular AI coding assistant, Claude Code. Anthropic also reported a $47 billion revenue run rate on Thursday. That’s up from $30 billion run rate earlier this year, and $10 billion in revenue last year.
The company released its latest model, Claude Opus 4.8, earlier on Thursday. Anthropic has also captivated Wall Street by unveiling Claude Mythos Preview, a model with advanced cybersecurity capabilities that’s only available to a select group of companies.
“Claude is increasingly indispensable to our growing global community of customers, and we work tirelessly to make tools like Claude Code and Cowork more helpful, more powerful, and more adaptable to their needs,” Anthropic CFO Krishna Rao said in Thursday’s press release. “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.”
Anthropic’s latest round comes as the leading AI model makers prepare to go public.
Elon Musk’s SpaceX, parent company of his AI startup SpaceXAI, filed its prospectus with the Securities and Exchange Commission last week on its way to an initial public offering.
When Musk merged SpaceX with his AI startup in February, the combined company was valued at $1.25 trillion.
OpenAI is preparing to file its confidential IPO prospectus in the coming days or weeks, CNBC has confirmed.
The Sam Altman-led startup is looking to go public as soon as September, a source familiar with the matter said. The person spoke on condition of anonymity in order to discuss internal decisions.
Not to be left too far behind, Anthropic is also getting IPO ready behind the scenes, though timing on the effort remains fluid, CNBC previously reported.
