Anthropic completes $65 billion Series H funding, with a post-money valuation of $965 billion, surpassing OpenAI to become the world's most highly valued AI startup. (Previous context: Anthropic's revenue overtakes OpenAI: a historic reversal in the AI arms race) (Background: SoftBank's market cap breaks 43 trillion yen, OpenAI IPO expectations drive stock price up 40% in one week) Announced the completion of $65 billion Series H funding, with a post-money valuation reaching $965 billion, surpassing OpenAI to become the world's most highly valued artificial intelligence company. A company founded less than three years ago now has annualized revenue exceeding $47 billion, and as the world's most highly valued AI startup, it has completed one of the largest private placements in history. On the 28th, Anthropic announced the funding round. The investor lineup behind the $965 billion valuation This round was led by Altimeter Capital, Dragoneer, Greenoaks, and Sequoia Capital. Co-leads include Capital Group, Coatue, D1 Capital Partners, GIC (Government of Singapore Investment Corporation), ICONIQ, and XN. Sovereign funds and traditional institutional investors including Blackstone, Fidelity, and Temasek also participated. Notably, $15 billion of the $65 billion comes from previously committed investments by hyperscale cloud providers. Simply put, cloud giants such as Amazon and Google had already locked in Anthropic through compute purchase agreements, and this $15 billion merely converts existing compute commitments into equity form, with Amazon contributing $5 billion. Sequoia partner Alfred Lin described in a statement that Anthropic is "redefining the boundaries of what's possible with AI applications." Altimeter founder Brad Gerstner directly positioned this funding round as "the most important infrastructure investment of this generation." On the strategic level, Micron, Samsung, and SK hynix — three memory and logic chip suppliers — also joined as "strategic infrastructure partners," locking in the global critical semiconductor supply chain. This combination reveals a signal: Anthropic is transforming from a model company into a core node of the compute ecosystem. The compute landscape: Anthropic's CFO (Chief Financial Officer) Krishna Rao stated that this round of funding will be invested in three directions: safety and interpretability research, compute expansion, and the extension of products and partnerships. The scale of compute expansion is quite concrete. Anthropic has signed an agreement with Amazon for up to 5 GW of new capacity; at the same time, it has signed agreements with Google and Broadcom for 5 GW of next-generation TPU capacity; and obtained GPU capacity for Colossus 1 and Colossus 2 from SpaceX. What is the concept of 5 GW of compute? Simply put, this is equivalent to the continuous output power of a medium-sized nuclear power plant, entirely dedicated to running AI model training and inference. By comparison, in 2023, the world's top AI training clusters were mostly under 100 MW. Anthropic is betting on the next generation of model training demand at a scale five to ten times that of mainstream infrastructure. In terms of cloud deployment, Claude is already the first frontier model to be simultaneously available on AWS, Google Cloud, and Microsoft Azure — the three major clouds. The same model can be called from three clouds simultaneously, so enterprise customers don't need to bind themselves to a specific cloud provider in order to use Claude.
