Anthropic said Thursday it has closed a $65 billion Series H funding round at a $965 billion post-money valuation, according to a company announcement and comments from Chief Financial Officer Krishna Rao, vaulting the Claude developer past OpenAI to become the world’s most valuable private artificial-intelligence startup.

The round was co-led by Altimeter Capital, Dragoneer, Greenoaks, and Sequoia Capital, with additional backing from Capital Group, Coatue, D1 Capital Partners, Baillie Gifford, Blackstone, Brookfield, D.E. Shaw Ventures, DST Global, and Fidelity Management & Research. Anthropic indicated the financing could be among its final private raises before pursuing a public listing.

The valuation marks one of the fastest wealth surges ever recorded in the technology sector. Anthropic was valued at roughly $380 billion during its Series G financing in February and approximately $183 billion during a prior funding round last September. The latest valuation nearly triples the February figure in just a few months, reflecting the speed at which institutional capital continues flooding into the AI sector.

Driving the surge is revenue growth.

Anthropic disclosed that its annualized revenue run rate has climbed to approximately $47 billion, up sharply from around $30 billion earlier this year and roughly $10 billion in revenue generated during 2025. A major contributor has been Claude Code, the company’s AI-powered software-development platform, which has rapidly gained adoption among enterprises, engineering teams, and independent developers seeking productivity gains and automation tools.

The financing reshuffles the balance of power across Silicon Valley’s AI race.

OpenAI, maker of ChatGPT, was valued at approximately $852 billion following its March financing round, which itself had been viewed as unprecedented in scale. Anthropic’s new valuation now moves decisively ahead of that figure, signaling that investors increasingly see enterprise-focused AI infrastructure and coding systems as one of the sector’s most commercially scalable businesses.

For businesses watching the AI market from the sidelines, the funding wave sends a broader message: Wall Street believes companies are still in the early innings of adopting artificial intelligence into everyday operations.

The firms writing checks into Anthropic are effectively betting that businesses will continue paying for AI systems capable of writing software, generating documents, analyzing data, automating workflows, reducing staffing burdens, and accelerating operational decision-making. The scale of the raise suggests major investors expect AI spending to expand significantly rather than cool off.

Anthropic also used Thursday’s announcement to unveil new products aimed at enterprise customers.

The company introduced Claude Opus 4.8, its latest flagship model, alongside a new cybersecurity-focused platform called Claude Mythos Preview, which will initially be offered to a limited number of approved corporate and government users. Rao said the new capital would help Anthropic scale infrastructure, expand enterprise deployment, and maintain what he described as a research lead against rivals.

The timing also reflects how quickly the AI industry is converging with public capital markets.

Several of the largest artificial-intelligence developers are already preparing for eventual IPOs. Elon Musk’s AI venture, folded earlier this year into the broader SpaceX ecosystem, recently filed offering paperwork tied to a combined business reportedly valued near $1.25 trillion. Investors increasingly expect Anthropic and OpenAI to follow similar paths as demand for AI infrastructure, chips, cloud services, and enterprise automation tools continues accelerating.

Analysts say the newest valuation milestones underscore a deeper transformation underway across the global economy.

Unlike earlier technology cycles centered primarily on consumer apps or advertising, today’s AI investment boom is increasingly tied to operational infrastructure — tools businesses directly use to save time, automate labor, improve productivity, and increase margins. That distinction is helping justify valuations once considered impossible even in Silicon Valley.

Whether Anthropic moves quickly toward an IPO now becomes one of the biggest open questions in the technology market. Company filings and industry reports have pointed to growing internal preparations, including expanded legal and financial advisory work associated with public-market readiness.

For now, Anthropic has crossed a threshold almost no startup ever reaches — and in doing so, it has redrawn the hierarchy at the center of the global AI economy.
