Anthropic raised $65 billion [1] in a Series H financing round on Thursday, making it the most valuable artificial-intelligence startup in the U.S.

This funding shift signals a change in the competitive landscape of generative AI. By overtaking its primary rival, OpenAI, Anthropic establishes a massive capital reserve to accelerate the development of next-generation models and infrastructure.

The funding round places the company's valuation near the $1 trillion mark. Reports on the exact figure vary, with The Hill citing a valuation of $965 billion [2], while The New York Times reported it at $900 billion [3].

This surge in value moves Anthropic past OpenAI, which had a prior valuation of $730 billion [4]. The capital infusion is intended to secure the resources necessary for further AI development and to maintain a competitive edge in a rapidly evolving market.

Based in Silicon Valley, California, Anthropic has focused on building reliable and steerable AI systems. The company is now positioned with the largest private valuation in the sector's history, a milestone that reflects investor confidence in its long-term trajectory.

The race for AI dominance has transitioned from a battle of early prototypes to a war of capital and compute. With billions of dollars in new funding, the company can now scale its operations and research capabilities to compete with the largest technology firms in the world.

The valuation jump indicates that investors are betting on Anthropic's specific approach to AI safety and development over OpenAI's. As these startups approach trillion-dollar valuations, the barrier to entry for new competitors rises, effectively consolidating the AI market into a few hyper-funded entities with the capacity to afford the massive computing costs required for frontier models.
