Anthropic PBC raised $65 billion [1] in a new funding round on May 28, 2026, overtaking rival OpenAI in total market valuation.
This capital injection signals a shift in the artificial intelligence landscape, as the San Francisco-based startup now holds the highest valuation among private AI firms. The move positions Anthropic as a dominant force in the race to develop next-generation AI models while providing the liquidity necessary for a potential public debut.
Reports on the company's post-money valuation vary between $900 billion [1] and $965 billion [2]. This range places Anthropic significantly ahead of OpenAI, which was previously valued at $730 billion [1].
The funding round is intended to support continued AI development and prepare the company for a forthcoming initial public offering [3]. By securing these funds, Anthropic aims to cement its lead over competitors in a market characterized by extreme capital requirements for computing power, and talent.
Anthropic has focused its strategy on safety and reliability in AI systems. The massive increase in valuation reflects investor confidence that the company's approach can scale effectively against the industry leader. The company remains headquartered in San Francisco, California [1].
As the AI sector matures, the competition for dominance is no longer just about technical capabilities but also about the ability to attract massive institutional capital. This latest round represents one of the largest funding events for a private technology company in history.
