Artificial intelligence company Anthropic has secured $65 billion in fresh funding, pushing its post-investment valuation to $965 billion and cementing its position among the world’s most valuable privately held technology firms ahead of a potential public listing.
The Series H funding round attracted participation from several leading global investment firms, including Altimeter Capital, Dragoneer, Greenoaks, Sequoia Capital, Capital Group, Coatue, and D1 Capital Partners.
Additional investors in the round included Baillie Gifford, Blackstone, Brookfield, DST Global, and Fidelity Management & Research, reflecting sustained investor confidence in the rapidly expanding AI sector.
The funding package also incorporates $15 billion in previously committed investments from major cloud providers, including a $5 billion commitment from Amazon announced earlier this year. Strategic infrastructure partners such as Samsung, SK Hynix, and Micron also joined the round to support Anthropic’s growing computing needs.
According to the company, the fresh capital will be deployed to expand computing infrastructure, accelerate the development of its Claude family of AI products, and deepen research into AI safety, interpretability, and reliability.
The announcement coincided with the release of Claude Opus 4.8, Anthropic’s latest model designed to enhance coding performance, advanced reasoning, and improved honesty and self-correction capabilities.
Anthropic has recorded rapid growth since its previous fundraising round in February, driven largely by increasing enterprise demand for products such as Claude Code and other AI-powered workplace solutions. The company disclosed that its annualised revenue run rate surpassed $47 billion earlier this month.
“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,” said Krishna Rao, Chief Financial Officer at Anthropic.
“This funding will help us meet the historic demand we are experiencing, remain at the frontier of AI research, and bring Claude to more environments where work happens,” he added.
To support growing demand, Anthropic also announced new infrastructure agreements with Amazon, Google, Broadcom, and SpaceX aimed at securing additional computing power.
Under the agreements, Amazon is expected to provide up to five gigawatts of computing capacity, while Google and Broadcom will contribute next-generation Tensor Processing Unit (TPU) infrastructure. SpaceX will also support access to Graphics Processing Unit (GPU) resources through its Colossus systems.
Anthropic disclosed that Claude is now available across Amazon Web Services (AWS), Google Cloud, and Microsoft Azure, with AWS remaining its primary cloud and training partner.
Industry investors backing the company expressed strong confidence in Anthropic’s long-term growth prospects.
“Claude’s latest advancements have driven large-scale adoption among some of the world’s most demanding organisations. This momentum positions Anthropic to lead the next phase of AI innovation and capture the enormous opportunity ahead,” said Brad Gerstner, Founder and CEO of Altimeter Capital.
Marc Stad, Managing Partner at Dragoneer, described the pace of AI innovation as unprecedented, noting that the industry remains in the early stages of both development and commercialisation.
Similarly, Neil Mehta, Founder and Managing Partner at Greenoaks, said Anthropic’s culture, mission, and commercial momentum continue to reinforce one another, strengthening investor confidence.
Anthropic’s latest raise comes amid intensifying competition among leading AI companies seeking greater market share, stronger infrastructure, and fresh capital ahead of eventual public offerings.
Earlier this year, OpenAI completed a funding round that reportedly valued the company at $852 billion after investment, while Elon Musk’s xAI, now merged with SpaceX, has reportedly targeted a $2 trillion valuation as it prepares for a future public market debut.
