Anthropic has raised $65 billion in funding at a $965 billion post-money valuation in its latest funding round, marking what could be the AI startup’s last private fundraising before debuting on the public markets.
The Series H round was co-led by Altimeter Capital, Dragoneer, Greenoaks, Sequoia Capital, Capital Group, Coatue, D1 Capital Partners, and others. Institutional investors including Baillie Gifford, Blackstone, Brookfield, D.E. Shaw Ventures, DST Global, and Fidelity Management & Research also participated. Strategic infrastructure partners — Samsung, SK Hynix, and Micron — joined as well.
A portion of the round, $15 billion, is made up of previously committed investments from hyperscalers, including $5 billion from Amazon announced in April.
Anthropic plans to use the new funds to advance safety and interpretability research, expand compute capacity to meet growing demand for Claude, and scale products and partnerships.
The round coincides with Anthropic’s release of its new Claude Opus 4.8 model, which the company says offers improved capabilities in agentic tasks, advanced coding, and a focus on honesty and self-correction. The company is also reportedly planning a broader launch of models comparable to its Mythos cybersecurity model, which has so far been released in limited fashion due to safety concerns.
Anthropic said its annualized run rate revenue crossed $47 billion earlier this month. The Wall Street Journal recently reported that the startup expects a 130% revenue surge that would bring it to its first operating profit.
“Claude’s latest advancements have driven large-scale adoption among the world’s most demanding organizations. 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.
Anthropic has been in close competition with OpenAI for fundraising and user growth ahead of their respective IPOs. OpenAI last raised a $122 billion round in March at an $852 billion post-money valuation.
