TL;DR
Anthropic said it closed a $65 billion Series H at a $965 billion post-money valuation on May 28, 2026. The financing is framed by the company’s own disclosures as a capacity push, with Micron, Samsung and SK hynix named as strategic infrastructure partners and more than 10 gigawatts of compute commitments cited.
Anthropic said on May 28, 2026, that it closed a $65 billion Series H funding round at a $965 billion post-money valuation, a financing that makes the AI company one of the most valuable private companies in the world and sharpens focus on whether its fast-growing Claude business can absorb a vast new wave of computing capacity.
The company’s valuation has risen from $61.5 billion in March 2025 to $965 billion in May 2026, according to the source material, a roughly 15.7-fold increase in about 14 months. The round follows a February 2026 Series G that valued Anthropic at $380 billion post-money and came as the company reported $14 billion in run-rate revenue.
Anthropic’s current run-rate revenue is cited at $47 billion as of May 2026, up from $14 billion in February. On those figures, the revenue multiple fell from about 27 times at the Series G to about 20.5 times at the Series H, even as the headline valuation more than doubled. That does not make the price low by historical software standards, but it changes the shape of the debate: revenue growth, as reported, is outpacing valuation growth.
The more revealing part of the announcement is the infrastructure language. Anthropic named Micron, Samsung and SK hynix as strategic infrastructure partners and itemized more than 10 gigawatts of compute commitments across multi-year arrangements. The source material frames the round less as a conventional valuation event than as a financing tied to capacity, with more than $200 billion in announced compute spending cited across contracts.
Why It Matters
The financing matters because it links the next phase of frontier AI competition to physical infrastructure rather than only model quality, product adoption or fundraising access. By naming major memory chipmakers alongside cloud and hardware partners, Anthropic is signaling that supply of compute, memory and data center capacity may be the main constraint on growth.
For customers, the issue is whether Anthropic can keep Claude available, fast and widely deployed as enterprise demand rises. For investors and competitors, the question is whether the company’s revenue trajectory can support infrastructure commitments at a scale closer to energy and semiconductor planning than traditional software expansion.
The round also changes the competitive map. The source material says the valuation puts Anthropic ahead of OpenAI’s March valuation of $852 billion. That ranking may shift again as private AI companies raise new capital, but the May 28 announcement places Anthropic at the center of the market’s largest private-capital bet on AI demand.

Background
Anthropic has moved through five major valuation steps in roughly 14 months, according to the source material. The company was valued at $61.5 billion in March 2025, then reached $380 billion after its Series G in February 2026, before the new $965 billion post-money valuation in May 2026.
The company’s reported revenue ramp is also central to the story. The source material says Anthropic grew from roughly $1 billion to $47 billion in run-rate revenue in 17 months, with enterprise AI spend share rising from about 10% to more than 65% over the past year. Those figures are company-side claims or source-reported metrics and should be read alongside the caveat that some revenue may be gross of cloud-reseller pass-throughs.
Anthropic’s position is helped by distribution across major clouds and partnerships with Amazon, Google, Broadcom, Microsoft, Nvidia, SpaceX and Fluidstack, according to the source material. The new emphasis on Micron, Samsung and SK hynix adds memory supply to that partner map.
“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.”

What Remains Unclear
Several major points remain unclear. Anthropic has not provided a full public breakdown of the Series H investor allocation, the exact financial terms of each compute commitment, or how much of the reported run-rate revenue is net of cloud-reseller and infrastructure pass-through arrangements.
It is also not yet clear how quickly the committed capacity will come online, what utilization rates Anthropic expects, or how much margin the company can retain as spending on chips, cloud services, power and data center capacity rises. The source material says profitability is still about two years away, but that timeline depends on demand, pricing, capacity delivery and continued model progress.

What’s Next
The next test is execution over the next 18 to 24 months, as the committed gigawatts of capacity are delivered and Anthropic works to convert them into paid usage. Investors, customers and rivals will watch revenue growth, gross margin, cloud economics, enterprise adoption and any signs that demand is falling short of the infrastructure buildout.

Key Questions
What did Anthropic announce?
Anthropic said it closed a $65 billion Series H funding round at a $965 billion post-money valuation on May 28, 2026.
Why is the round being described as a compute bet?
The announcement named Micron, Samsung and SK hynix as strategic infrastructure partners and cited more than 10 gigawatts of compute commitments. That suggests the financing is tied to securing capacity for future Claude demand.
Is Anthropic now more valuable than OpenAI?
According to the source material, Anthropic’s $965 billion post-money valuation exceeds OpenAI’s March 2026 valuation of $852 billion. Private-company valuations can change quickly and may not be directly comparable across financing structures.
Does the lower revenue multiple mean the valuation is cheap?
No. The source material says Anthropic’s revenue multiple compressed from about 27 times to about 20.5 times between February and May 2026, but that remains high by historical software standards.
What is the biggest unresolved risk?
The main open question is whether Anthropic can turn massive compute commitments into durable, profitable demand. If capacity arrives faster than paying usage, the infrastructure burden could pressure the company’s economics.
