Anthropic raised $65 billion [1] in a new funding round on Thursday, May 28, 2026, making it the most valuable AI startup globally.

This financial surge signals a shift in the competitive landscape of artificial intelligence. By securing massive capital, Anthropic positions itself to accelerate the development of its Claude chatbot and challenge the dominance of established rivals in a high-stakes arms race.

The funding round has pushed Anthropic's post-money valuation to between $900 billion [3] and $965 billion [2]. This figure surpasses the last reported valuation of OpenAI, which stood at $730 billion [4].

The company sought the additional capital to support rapid growth and maintain a competitive edge in the industry [1]. The scale of the investment reflects the immense costs associated with training next-generation large language models, and the infrastructure required to host them.

While the company has not yet reached the $1 trillion milestone, the current valuation puts it within reach of that mark [2]. This growth occurs as the AI sector continues to attract unprecedented levels of private investment, despite increasing scrutiny over the profitability of generative AI tools.

Anthropic's rise to the top of the AI valuation ladder underscores the volatility and rapid scaling of the sector. The company now holds the financial leverage to aggressively expand its research and deployment capabilities — a move that may force other startups to seek similar capital injections to remain viable.

The shift in valuation leadership from OpenAI to Anthropic suggests that investors are diversifying their bets within the generative AI space. As the cost of compute and talent continues to climb, the ability to raise tens of billions of dollars becomes a primary strategic advantage, transforming the AI race from a purely technical competition into a war of financial attrition.
