Anthropic raised $65 billion [1] in a Series H funding round on Thursday, May 28, 2026, valuing the company at roughly $965 billion [1].
This valuation shift is significant because it positions Anthropic as the most valuable artificial intelligence company, dethroning its primary competitor, OpenAI. The surge in capital reflects a growing investor appetite for diverse AI architectures and the scale of resources required to develop next-generation models.
The funding round included substantial investments from Altimeter Capital, Dragoneer, Greenoaks, and Sequoia Capital [1]. According to reports, each lead investor contributed more than $2 billion [1] to the round. These funds are intended to accelerate Anthropic’s AI development and solidify its market position.
Market estimates of the company's total worth vary slightly across financial reports. While some sources cite a valuation of $965 billion [1, 3], Forbes reported the figure at $900 billion [2]. Meanwhile, secondary market data from Yahoo Finance suggests an implied valuation of approximately $1 trillion [5].
This capital influx allows Anthropic to compete more aggressively with OpenAI in the race for artificial general intelligence. By securing such a high valuation, the company increases its ability to attract top talent and acquire the massive computing power necessary for training larger models, a critical bottleneck in the current AI industry.
Despite the different figures reported by analysts, the consensus remains that Anthropic has overtaken OpenAI in total estimated value [2, 3]. The funding represents one of the largest private investment rounds in the history of the technology sector.

The shift in valuation reflects a broader trend of institutional investors diversifying their bets within the AI sector. By pushing Anthropic's valuation near $1 trillion, the market is signaling that the 'winner-take-all' narrative surrounding OpenAI is fading. This creates a more competitive landscape where capital abundance allows multiple firms to pursue computationally expensive research simultaneously.
