Anthropic raises $65B in final round before IPO, nears $1 trillion valuation

AI startup Anthropic has closed a $65 billion Series H funding round, pushing its valuation to $965 billion. The raise is expected to be the company's last major private fundraise before an anticipated IPO.

San Francisco-based AI company Anthropic has completed a $65 billion Series H funding round, bringing its post-money valuation to $965 billion — just shy of the $1 trillion mark. The raise is widely seen as the startup's final major private financing ahead of a long-anticipated initial public offering.

The colossal round underscores the intense investor appetite for artificial intelligence companies, particularly those competing at the frontier of large language model development. Anthropic, founded in 2021 by former OpenAI researchers including Dario Amodei, has positioned itself as a safety-focused alternative to rivals such as OpenAI and Google DeepMind.

With a valuation approaching $1 trillion, Anthropic would rank among the most valuable companies in the world upon going public. The figure places it in rare company, comparable to some of the largest publicly listed technology giants by market capitalization. Industry analysts have noted that the timing and scale of the Series H suggests the company is actively preparing its books and governance structures for public market scrutiny.

Anthropic's flagship product, the Claude family of AI assistants, has gained significant traction across enterprise customers and developers. The company has secured major cloud partnerships, including substantial commitments from Amazon and Google, providing both capital and distribution infrastructure to compete in an increasingly crowded AI market.

The IPO, if it proceeds, would represent one of the most significant technology listings in recent years and a landmark moment for the generative AI sector as a whole.
