Anthropic, the AI firm behind the Claude chatbot, announced on Thursday it had raised $65bn in funding to value the company at $965bn post-money. The move makes Anthropic the world’s most valuable AI startup, eclipsing its competitor OpenAI.

The deal marks an exceedingly successful period of growth for Anthropic, which was once considered to be a smaller player in the global AI arms race. The widespread adoption of its products by large enterprise businesses, especially following its release of powerful coding assistants late last year, has turned it into a dominant player in the industry.

Anthropic’s new valuation cements a reshuffling of the AI industry’s power dynamics, putting a dollar figure on Claude’s increased cultural and commercial prominence. The deal is also likely to have implications for this year’s blockbuster slate of initial public offerings, which includes rivals OpenAI and SpaceX.

The company touted the new funding round, which was led by Altimeter Capital, Dragoneer, Greenoaks, and Sequoia Capital, as proof that its AI models and vision for the future of the technology are winning out.

“Claude is increasingly indispensable to our growing global community of customers, and we work tirelessly to make tools like Claude Code and Cowork more helpful, more powerful, and more adaptable to their needs,” Krishna Rao, chief financial officer of Anthropic, said in a blogpost.

In addition to orienting its business more towards enterprise and coding services than some of its consumer-forward competitors, Anthropic has also postured itself as a more safety-focused company. One of Anthropic’s co-founders was present earlier this month at Pope Leo’s release of a more than 43,000-word encyclical which warned against the dangers of AI and called for a reining-in of the technology.

The firm is also still locked in a legal battle with the Pentagon following its refusal earlier this year to remove safeguards that would allow Claude to be used for mass domestic surveillance or lethal autonomous weapons systems, which could kill people without human input. The US government has reportedly used Claude for military operations including missile strikes on Iran and the capture of Nicolás Maduro, the Venezuelan leader.

The White House was forced to ease its feud with Anthropic somewhat in recent weeks, however, after the company announced that it was withholding the release of its latest Mythos model over cybersecurity concerns. The episode sparked a small-scale geopolitical crisis as nations worried about vulnerabilities to financial systems and critical infrastructure, as well as prompting a call from JD Vance, the US vice-president, to the heads of AI companies urging their cooperation.

Anthropic is additionally set to be an influential force in the US midterm elections, pouring millions into lobbying efforts and Super Pacs aimed at candidates and legislation that aligns with its views on regulating AI. The firm has called for more government oversight of the technology, breaking with other tech industry leaders and OpenAI which advocate for a more lax regulatory framework.

The company’s valuation underscores the enormous amounts of money still flowing into the AI industry, despite widespread public distrust of the technology. Anthropic’s valuation follows OpenAI raising $122bn in March to be valued at $852bn, with the possibility it will seek a $1tn IPO later this year.
