TL;DR
Anthropic said it closed a $65 billion Series H at a $965 billion post-money valuation on May 28, 2026. The round appears aimed at funding compute capacity, with Micron, Samsung and SK hynix named as strategic infrastructure partners and more than 10 gigawatts of capacity commitments cited.
Anthropic said Thursday it closed a $65 billion Series H round at a $965 billion post-money valuation, a financing that would make it the world’s most valuable private company and place compute capacity at the center of its next phase of growth.
The company said the round values Anthropic at $965 billion after the investment, up from a reported $61.5 billion valuation in March 2025. The new financing also puts Anthropic above OpenAI’s March 2026 valuation of $852 billion, according to the source material.
The funding announcement is tied to infrastructure as much as capital. Anthropic named Micron, Samsung and SK hynix as “strategic infrastructure partners” and cited more than 10 gigawatts of compute commitments. The company’s broader compute spending was described as more than $200 billion across multi-year contracts.
Anthropic’s reported run-rate revenue was $47 billion as of May 2026, up from $14 billion in February 2026. On those figures, the company’s revenue multiple fell from roughly 27 times at its February Series G to about 20.5 times after the Series H, even as its valuation rose sharply.
Why It Matters
The financing matters because it shows how frontier AI companies are being valued less like traditional software firms and more like infrastructure-heavy operators racing to secure scarce computing resources. The round is not only a capital raise; it is a bet that demand for Claude and related enterprise AI services will absorb a much larger compute base.
The scale also affects the wider AI market. Large private valuations can shape hiring, cloud contracts, chip supply, investor expectations and the capital needs of rivals. If Anthropic can fill the promised capacity with paying demand, the financing could support a new revenue tier for AI companies. If demand slows or model progress stalls, the same commitments could become a major financial exposure.

Background
Anthropic’s valuation has risen from $61.5 billion in March 2025 to $965 billion in May 2026, according to the source material. That 14-month climb is unusual for enterprise software and reflects the speed at which leading AI labs have converted model access, cloud distribution and enterprise adoption into revenue.
The Series H follows a February 2026 Series G that reportedly raised $30 billion at a $380 billion post-money valuation. The new round more than doubles that valuation in just over three months, while reported run-rate revenue grew even faster over the same period.
The infrastructure details are central to the story. The naming of memory chipmakers alongside cloud and technology partners points to supply constraints beyond software development, including chips, data centers, power and delivery schedules.

What Remains Unclear
Several details remain unclear. The announcement, as summarized in the source material, does not specify the full investor list, exact contract terms, capacity delivery dates, pricing assumptions or how much of reported revenue reflects direct usage versus cloud-reseller pass-throughs.
It is also not yet clear how quickly the more than 10 gigawatts of committed capacity will come online, how much will be used at high utilization, or when Anthropic will reach profitability. The core open question is whether demand grows fast enough to justify the scale of the compute commitments.

What’s Next
The next test is execution over the next 18 to 24 months, as contracted compute capacity is delivered and Anthropic tries to convert infrastructure access into sustained revenue growth. Investors, customers and rivals will be watching capacity utilization, enterprise adoption, margins and any further financing tied to data centers, chips or cloud partnerships.
