Generative AI company Anthropic announced on Thursday that it has raised $65 billion in a Series H funding round, more than doubling its post-money valuation to a staggering $965 billion.
That means the San Francisco-based startup has now surpassed its closest rival, OpenAI, in terms of valuation. In February, OpenAI announced it had closed a $110 billion round at an $840 billion post-money valuation. That financing marked the largest raise ever, according to Crunchbase data.
Altimeter Capital, Dragoneer, Greenoaks and Sequoia Capital led Anthropic’s latest raise. Capital Group, Coatue, D1 Capital Partners, GIC, Iconiq Capital and XN co-led the round. The financing also included $15 billion of previously committed investments from hyperscalers, including $5 billion from Amazon, which, interestingly, also participated in OpenAI’s most recent round of funding.
Anthropic’s massive round comes just over three months after the startup raised $30 billion in a Series G that valued it at $380 billion post-money. It has now raised nearly $144 billion since its 2021 inception, per Crunchbase.
Since that round, Anthropic says it has grown its enterprise customer base. Its run-rate revenue crossed $47 billion earlier this month, according to the company.
“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,” said Krishna Rao, chief financial officer of Anthropic, in a blog post. “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.”
