Anthropic just raised $65 billion in a single funding round. The Claude AI maker’s Series H, completed on May 28, closed at a post-money valuation of $965 billion, making it the most valuable AI startup on the planet, leapfrogging OpenAI in the process.
Around June 1, Anthropic filed a confidential S-1 registration statement with the SEC. If the IPO moves forward later this year, it could rank among the largest in US financial history. The company’s valuation trajectory tells the story: Anthropic was worth roughly $60 billion in early 2025. By mid-2026, that number has ballooned to nearly $1 trillion.
The Series H round was led by Altimeter Capital, Dragoneer, Greenoaks, and Sequoia Capital. Strategic investors Amazon, Google, Microsoft, and Nvidia all participated.
