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 less at balance-sheet optics than at funding large compute commitments, including more than 10 gigawatts of capacity and partnerships tied to memory-chip supply.
Anthropic said Thursday that it closed a $65 billion Series H round at a $965 billion post-money valuation, a financing that the company’s own details frame as a large-scale bet on compute capacity as much as a record-setting private funding round.
Essential Details
The May 28, 2026 round values Anthropic above the $852 billion valuation attributed to OpenAI in March 2026, according to the source material. Anthropic’s valuation has risen from $61.5 billion in March 2025 to $965 billion in roughly 14 months, a 15.7-times increase.
The company also reported a $47 billion revenue run rate as of May 2026, up from $14 billion in February 2026. On those figures, the revenue multiple fell from about 27 times at the Series G valuation of $380 billion to about 20.5 times at the Series H valuation, meaning reported revenue grew faster than valuation over that three-month period.
The more material part of the deal may be its infrastructure details. Anthropic named Micron, Samsung and SK hynix as “strategic infrastructure partners” and cited more than 10 gigawatts of committed compute capacity. The source material also points to more than $200 billion in announced compute spending across multi-year contracts, making the $65 billion raise closely tied to physical capacity needs.

Why It Matters
The round shows how frontier AI companies are being valued not only as software businesses, but as buyers and organizers of massive computing infrastructure. If Anthropic can turn that capacity into paying demand, the financing could support a larger enterprise AI business. If demand, margins or model progress fall short, the same commitments could become a major financial exposure.
The deal also signals a shift in what investors may see as the limiting factor in advanced AI. Naming memory suppliers alongside cloud and chip partners suggests Anthropic is treating access to compute, memory and data-center capacity as a core strategic asset, not a back-office procurement issue.

Context
Anthropic’s prior Series G in February 2026 raised $30 billion at a $380 billion post-money valuation, according to the source material. Three months later, the Series H more than doubled that valuation while reported run-rate revenue more than tripled.
The source material compares Anthropic’s reported growth with historical enterprise software timelines, saying Salesforce took roughly two decades to reach revenue levels Anthropic now reports. That comparison is useful for scale, but it does not settle whether Anthropic’s revenue quality, margins or cost structure resemble traditional software companies.
Anthropic’s cloud and infrastructure relationships include Amazon, Google, Microsoft, Broadcom, Nvidia, SpaceX and Fluidstack, according to the source material. The new emphasis on Micron, Samsung and SK hynix points toward memory supply as a constraint for future AI training and inference capacity.

What Remains Unclear
What Remains Unclear
It is not yet clear how much of the $47 billion run-rate revenue is net revenue after cloud-reseller pass-throughs, how quickly the committed compute capacity will come online, or whether customer demand will fill that capacity at margins that support the valuation.
Profitability also remains unresolved. The source material says profitability is two years out, but the timing and path depend on compute costs, pricing, enterprise demand and continued model progress.
What’s Next
What Happens Next
The next test is execution over the next 18 to 24 months, as the committed gigawatts of capacity come online. Investors and customers will be watching whether Anthropic can convert that infrastructure into durable revenue, improve margins and keep pace with competing frontier AI labs.
Key Questions
What did Anthropic announce?
Anthropic said it closed a $65 billion Series H round at a $965 billion post-money valuation on May 28, 2026.
Why is the round being described as a compute bet?
The company named Micron, Samsung and SK hynix as infrastructure partners and cited more than 10 gigawatts of committed compute capacity, tying the financing to physical AI infrastructure needs.
Is Anthropic now worth more than OpenAI?
According to the source material, Anthropic’s $965 billion post-money valuation is above OpenAI’s March 2026 valuation of $852 billion.
Does the valuation mean Anthropic is profitable?
No. The source material says profitability is still about two years away. The valuation is based on growth expectations, reported revenue run rate and future capacity plans, not confirmed current profit.
What is the main risk?
The main risk is that Anthropic commits to large compute spending before demand, margins or model progress fully support it. The outcome depends on whether paying usage grows fast enough as new capacity becomes available.
