Anthropic Raises $65B in Series H Funding at $965B Post-Money Valuation
Confirming a spectacular momentum fueled by enterprises adoption
By Philippe Nicolas | June 4, 2026 at 2:01 pmAnthropic has raised $65 billion in Series H funding led by Altimeter Capital, Dragoneer, Greenoaks, and Sequoia Capital, valuing the company at $965 billion post-money.
Global enterprises across industries are deploying Claude in their core operations, and a growing number of people around the world use it for their everyday work. Since our Series G in February, adoption has continued to grow across global enterprise customers, and our run-rate revenue crossed $47 billion earlier this month. This latest funding is expected 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.
“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, CFO, Anthropic. “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.”
The round was co-led by Capital Group, Coatue, D1 Capital Partners, GIC, ICONIQ, and XN. Significant investors in this round include AMP PBC, Baillie Gifford, Blackstone, Brookfield, D.E. Shaw Ventures, DST Global, Fidelity Management & Research Company, General Catalyst, Insight Partners, Jane Street, Lightspeed Venture Partners, MGX, NTTVC, NX1 Capital, Situational Awareness LP, T. Rowe Price Associates, Inc., T. Rowe Price Investment Management, Inc., and Temasek. It also includes $15 billion of previously committed investments from hyperscalers, including $5 billion from Amazon.
Joining them are strategic infrastructure partners—Micron, Samsung, and SK hynix—whose technologies play a critical role in the world’s supply of memory, storage, and logic chips. As demand for Claude continues to grow, these relationships will help us scale our compute reliably at the pace our customers need.
We have significantly expanded our compute capacity in recent weeks. We signed agreements with Amazon for up to five gigawatts of new capacity, with Google and Broadcom for five gigawatts of next-generation TPU capacity, and with SpaceX for access to GPU capacity in Colossus 1 and Colossus 2. Claude is the first frontier model available on all three of the world’s largest cloud platforms: Amazon Web Services, Google Cloud, and Microsoft Azure. AWS remains our primary cloud provider and training partner.
“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.
“Dragoneer has long partnered with companies building the technology that will shape our future. Anthropic is helping pull forward this future, as intelligence becomes an increasingly critical ingredient to the way businesses operate and how their products show up in the world,” said Marc Stad, MP, Dragoneer. “The technological progress we are seeing right now is breathtaking. And we believe that we are still in the earliest days of both the development and commercialization of this technology.”
“Anthropic has built an organization in which the world’s best researchers and engineers operate with unmatched clarity of purpose, because they believe this is the most important work they will ever do,” said Neil Mehta, Founder and MP, Greenoaks. “Rarely has a company’s culture, mission, and commercial momentum reinforced each other so completely. We are honored to deepen our partnership.”
“Startups and Global 5000 companies alike are deploying Claude to handle complex workflows, and in doing so, Claude is learning how businesses actually operate: the context, the processes, the judgment,” said Alfred Lin, Partner, Sequoia Capital. “Anthropic is building the bridge between where enterprise AI stands today and where it’s headed.”
We are grateful for the support of our investors and partners as we continue building Claude for people and organizations around the world.
Comments
Make no mistake, the battle is fully engaged, and Anthropic now holds the momentum. Calling it a "battle" almost undersells it; this is a war. The amount raised is astronomical, the valuation surreal, nothing of this scale has ever moved this fast, and the company is already operating at a $47B run rate.
This round stands apart from the usual mega-round playbook because of who sits on the cap table. Strategic memory partners, Micron, Samsung, and SK hynix, came in as direct shareholders, while the compute footprint now stretches across three hyperscalers plus SpaceX. Anthropic locked in up to 5GW with Amazon, another 5GW of next-generation TPU capacity through Google and Broadcom, and GPU access in SpaceX's Colossus 1 and Colossus 2. Claude has become the first frontier model available across AWS, Google Cloud, and Microsoft Azure simultaneously. The trajectory is, frankly, spectacular.
Lining up OpenAI and Anthropic side by side, a few facts surface:
- OpenAI: $122B raised, $852B post-money (March 2026), ~$2B/month revenue, $13.1B for 2025
- Anthropic: $65B raised, $965B post-money, ~$47B run-rate revenue (May 2026)
The revenue gap jumps off the page. OpenAI's scale is built largely on ChatGPT consumer subscriptions, while Anthropic's $47B run rate is overwhelmingly enterprise and developer-driven, anchored by a deep portfolio of services: Claude Code, API consumption, Cowork, and Claude in Excel and Chrome. Investors are paying up for what they read as higher-quality, stickier B2B revenue, and meaningfully better gross margins than OpenAI's 33%.
Shift the lens to storage and memory, and several telling facts emerge.
Set against the structural HBM crunch that storage-industry trackers have been documenting for months, the Micron/Samsung/SK hynix investment is arguably the more consequential headline, more so than the dollar figure itself. It marks the first time these three memory chip giants have jointly backed the same AI company. Their combined annual capacity was already fully spoken for in Q1 2026, with a supply-demand gap estimated between 20% and 50%, a shortfall expected to drag on through 2028.
SK hynix held 57% of the HBM market in Q4 2025, with Samsung at 22% and Micron at 21%. Micron, for its part, disclosed in December that it would step back from consumer memory to concentrate on AI data center customers. Micron now carries a market cap of roughly $1.095 trillion, and SK hynix has also crossed the trillion-dollar threshold, both now rivalling Anthropic itself in market value.
A few closing observations:
- Anthropic has decisively won the enterprise round, for now. $47B run rate against OpenAI's ~$24B annualized speaks for itself
- Memory is the new oil. Putting Micron, Samsung, and SK hynix directly on the cap table signals that Anthropic's CFO sees the next 24 months being defined less by GPU access, now reasonably secured through the AWS/Google/SpaceX triad, and more by HBM allocation. For storage and memory observers, this is confirmation that AI demand is structurally reshaping DRAM and HBM roadmaps well into 2028
- The bubble question lingers. A $965B valuation on a $47B run rate works out to roughly 20x, not unreasonable by software standards, but only if growth holds and gross margins climb meaningfully above where OpenAI sits today
