Anthropic, a leading artificial intelligence startup, has successfully secured an additional $65 billion in funding, achieving a post-money valuation of $965 billion. This significant Series H round is anticipated to be the company's final private capital raise before it potentially enters the public markets.
The investment round was co-led by prominent firms including Altimeter Capital, Dragoneer, Greenoaks, Sequoia Capital, Capital Group, Coatue, and D1 Capital Partners, among others. A diverse group of institutional investors also participated, featuring Baillie Gifford, Blackstone, Brookfield, D.E. Shaw Ventures, DST Global, and Fidelity Management & Research.
Further bolstering the round, strategic infrastructure partners such as Samsung, SK Hynix, and Micron also contributed. Notably, $15 billion of the total funding comprises previously committed investments from hyperscalers, which includes a $5 billion contribution from Amazon initially announced in April.
The high demand for a stake in Anthropic was evident, with TechCrunch reporting last month that the company was nearing a $50 billion close, as investors eagerly sought to join its cap table. Illustrating this intense interest, one institutional investor reportedly pledged as much as $5 billion simply to secure a meeting with Anthropic CFO Krishna Rao.
Anthropic has outlined its strategic use for the newly acquired capital: to “advance our safety and interpretability research, expand compute to meet growing demand for Claude, and scale the products and partnerships our customers rely on.”
This funding announcement coincides with the release of Anthropic’s new Claude Opus 4.8 model, which boasts enhanced capabilities in agentic tasks, advanced coding, and a strong emphasis on honesty and self-correction. The AI startup is also reportedly planning a broader rollout of models equivalent to its powerful cybersecurity model, Mythos, which has previously been restricted to limited availability due to potential safety concerns.
The company has experienced substantial growth since its last funding round, particularly among enterprise clients who leverage its Claude Code offerings. Anthropic announced earlier this month that its run rate revenue surpassed $47 billion. Furthermore, The Wall Street Journal recently reported that the startup projects a remarkable 130% revenue surge, which is expected to lead to its first operating profit.
Brad Gerstner, Founder and CEO of Altimeter Capital, commented on the company's trajectory: “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.”
Anthropic finds itself in fierce competition with OpenAI, both vying for fundraising dominance and user growth as they approach their respective initial public offerings. Earlier this year, OpenAI secured a substantial $122 billion round in March, achieving an $852 billion post-money valuation.
In related market activity, Elon Musk’s SpaceX, which recently merged with xAI, is reportedly targeting an ambitious $2 trillion valuation for its forthcoming IPO, aiming to raise over $75 billion.
