Anthropic has secured $65 billion in fresh funding, a raise that values the artificial intelligence company at $965 billion after the investment. The company said the capital will support safety research, interpretability work, and a major expansion of compute to keep up with growing demand for Claude.
The financing round was led by Altimeter Capital, Dragoneer, Greenoaks, and Sequoia Capital. It also included co-leads Capital Group, Coatue, D1 Capital Partners, GIC, ICONIQ, and XN, along with a broad group of other investors. Anthropic said the round incorporates $15 billion in previously committed funding from hyperscale partners, including $5 billion from Amazon.
Anthropic said enterprise adoption of Claude has continued to accelerate since its Series G round in February. The company said its annualized revenue run rate surpassed $47 billion earlier this month, reflecting growing use of Claude among global businesses. Customers across industries are using the model in core operations, while more individual users are relying on it for daily work.
Chief Financial Officer Krishna Rao said the company is seeing historic demand and wants to use the new funding to improve tools such as Claude Code and Cowork. He said the investment should help Anthropic serve more customers, continue research at the frontier of the field, and make Claude available in more workplaces.
A central goal of the raise is to expand Anthropic’s computing capacity. The company has recently signed several large infrastructure deals, including an agreement with Amazon for up to five gigawatts of new capacity. It also announced five gigawatts of next-generation TPU capacity through Google and Broadcom, as well as access to GPU capacity through SpaceX’s Colossus 1 and Colossus 2 systems.
Anthropic said its cloud strategy now spans all three of the largest cloud platforms. Claude is available on Amazon Web Services, Google Cloud, and Microsoft Azure. AWS remains the company’s primary cloud provider and training partner.
The company also pointed to partnerships with Micron, Samsung, and SK hynix as part of its effort to secure the memory, storage, and logic chips needed to scale compute reliably. Anthropic said those relationships are important as demand continues to climb.
The company’s new backers framed the investment as a bet on enterprise AI adoption and on Anthropic’s position in the sector. Altimeter Capital founder and CEO Brad Gerstner said the latest progress from Claude has driven large-scale adoption among major organizations and gives Anthropic room to lead the next wave of AI development.
Dragoneer managing partner Marc Stad said the technology remains in its early commercial phase and argued that intelligence is becoming a key input for business operations. Greenoaks founder and managing partner Neil Mehta described Anthropic’s culture, mission, and commercial momentum as mutually reinforcing. Sequoia partner Alfred Lin said companies are using Claude for complex workflows and that the model is learning how businesses actually operate.
Anthropic’s latest raise comes as competition intensifies among major AI developers, many of which are spending heavily on infrastructure, chips, and model training. The company is positioning the new capital as both a response to current customer demand and a way to stay competitive in a rapidly expanding market.
