TL;DR
Anthropic announced a $65 billion Series H funding round at a $965 billion post-money valuation on May 28, 2026. The confirmed news is not only the valuation: the company said it will use the money to expand compute for Claude and named Micron, Samsung and SK hynix as strategic infrastructure partners.
As detailed in the original analysis, Anthropic said on May 28 that it raised $65 billion in Series H funding at a $965 billion post-money valuation, a financing that makes the Claude developer one of the world’s most valuable private AI companies and puts new focus on whether frontier AI winners will be decided by access to chips, memory and power.
Anthropic said the round was led by Altimeter Capital, Dragoneer, Greenoaks and Sequoia Capital, with Capital Group, Coatue, D1 Capital Partners, GIC, ICONIQ and XN among the co-leads. The company said its run-rate revenue crossed $47 billion earlier in May, up from the figures cited in prior private-market reports earlier this year.
The company said the new capital is expected to support safety and interpretability research, expand compute for Claude demand, and scale products and partnerships. The round includes $15 billion of previously committed investments from hyperscalers, including $5 billion from Amazon, according to Anthropic.
The compute signal came from the partner list. Anthropic named Micron, Samsung and SK hynix as strategic infrastructure partners, saying their technologies are tied to memory, storage and logic chips. Axios reported that the round pushed Anthropic past OpenAI’s most recent valuation, while AP reported that the company now ranks among the world’s most valuable startups.
Why It Matters
The financing matters because it shows how the AI race is moving from model releases alone to physical infrastructure. For Claude to serve more enterprise and consumer demand, Anthropic needs access to accelerators, high-bandwidth memory, data centers and electricity. The presence of major memory suppliers in the round suggests the company views chip availability as a business constraint, not only a procurement issue.
The valuation also sets a high bar. At $965 billion against a stated $47 billion revenue run rate, Anthropic is valued at about 20.5 times annualized revenue. That is lower than the multiple implied by some earlier figures cited in market coverage, but it is still a rich private-market price that depends on sustained demand, falling unit costs and the ability to turn compute spending into durable revenue.

Background
The Series H follows a string of infrastructure agreements. In April, Anthropic said it had expanded its Amazon partnership for up to 5 gigawatts of compute capacity for training and deploying Claude. The same month, Anthropic said it signed a new agreement with Google and Broadcom for multiple gigawatts of next-generation TPU capacity expected to come online starting in 2027.
Anthropic has said Claude is available through AWS, Google Cloud and Microsoft Azure. That distribution gives the company broad enterprise reach, but it also ties growth to cloud providers and hardware suppliers that may have their own AI ambitions.

What Remains Unclear
Several details remain unclear. Anthropic has not disclosed the full economic terms of the infrastructure partnerships, the size of the investments made by Micron, Samsung or SK hynix, the expected cost per unit of Claude inference, or the company’s current profitability.
It is also not yet clear how much of the reported revenue run rate comes from direct subscriptions, API usage, enterprise contracts or cloud-reseller channels. The largest open question is whether the new compute capacity will arrive on schedule and be matched by paying demand over the next 18 to 24 months.
