The newly raised capital is expected to strengthen Anthropic’s safety and interpretability research, expand compute infrastructure to meet rising demand for Claude, and scale the company’s products and strategic partnerships.
According to the company, global enterprises across multiple industries are increasingly deploying Claude in their core operations, while millions of users worldwide now rely on the platform for daily productivity tasks.
Krishna Rao, Chief Financial Officer of Anthropic, stated that Claude has become increasingly indispensable for the company’s growing global customer base.
In his words,
“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. This funding will help us serve the historic demand we are experiencing, stay at the research frontier, and bring Claude to more of the places where work happens.”

Philippe Laffont, Founder & Portfolio Manager of Coatue said,
“Since our initial investment in 2025, Anthropic’s focus on agentic coding and enterprise-grade AI systems has accelerated its progress toward large-scale adoption. The team’s ability to rapidly scale its offerings further positions Anthropic as a leader in a highly competitive AI market.”
Anthropic series H funding comes after its Series G funding round in February 2026. Recall that when it raised the funding earlier this year, the company stated that the investment will fuel the frontier research, product development, and infrastructure expansions that have made Anthropic the market leader in enterprise AI and coding.
Recently, Anthropic said adoption has accelerated significantly, with annualized revenue reportedly surpassing $47 billion earlier this month.
In recent weeks, the company has significantly expanded its compute capacity through agreements with Amazon for up to five gigawatts of new capacity, as well as collaborations with Google and Broadcom for five gigawatts of next-generation TPU capacity.
The company also secured access to GPU capacity through SpaceX’s Colossus 1 and Colossus 2 infrastructure. Notably, Anthropic noted that Claude is now the first frontier AI model available across the world’s three largest cloud platforms: Amazon Web Services, Google Cloud, and Microsoft Azure, with AWS remaining its primary cloud provider and training partner.
Business subscriptions to Claude Code have quadrupled since the start of 2026, and enterprise use has grown to represent over half of all Claude Code revenue.
Anthropic also highlighted that it trains and operates Claude using a diversified mix of AI hardware, including AWS Trainium chips, Google TPUs, and NVIDIA GPUs.
According to the company, this approach allows workloads to be matched with the most suitable hardware, resulting in improved performance and greater resilience for enterprise customers relying on Claude for mission-critical operations.
The company further stated that the growing demand from enterprises and developers reflects increasing trust in Claude for important business tasks.
As artificial intelligence moves toward large-scale implementation, Anthropic said it plans to continue investing in models, products, infrastructure, and strategic partnerships to strengthen its position in the evolving AI industry.
