TL;DR
Anthropic said it closed a $65 billion Series H at a $965 billion post-money valuation on May 28, 2026. The round is framed around compute capacity, including more than 10 gigawatts of commitments and partnerships with Micron, Samsung and SK hynix.
Anthropic announced Thursday, May 28, 2026, that it closed a $65 billion Series H round at a $965 billion post-money valuation, a financing that the company’s source material frames less as a conventional valuation milestone than as a large bet on securing compute capacity for future AI demand.
The round would make Anthropic the most valuable private company on Earth, according to the provided source material, placing it above OpenAI’s reported March 2026 valuation of $852 billion. Anthropic’s valuation has risen from $61.5 billion in March 2025 to $965 billion in May 2026, a 15.7-fold increase in about 14 months.
The company also reported $47 billion in run-rate revenue as of May 2026, up from $14 billion in February 2026, according to the source material. That means Anthropic’s revenue multiple fell from about 27 times at its Series G valuation of $380 billion to about 20.5 times at the new Series H valuation, even as the headline valuation more than doubled.
The financing is tied to infrastructure. Anthropic named Micron, Samsung and SK hynix as strategic infrastructure partners and itemized more than 10 gigawatts of compute commitments, according to the source material. The source also cites more than $200 billion in announced compute spend across multiyear contracts involving cloud, chip and infrastructure partners.
Why It Matters
The scale of the financing matters because it shows how frontier AI companies are being valued around access to physical infrastructure, not only software revenue or model performance. Memory chips, data centers, power and cloud capacity are becoming core inputs for companies trying to serve enterprise AI demand at global scale.
The valuation also complicates a simple bubble narrative. A 20.5 times revenue multiple remains high by historical software standards, but the source material says Anthropic’s revenue grew faster than its valuation between February and May 2026. That compression makes the round different from a case where investors are paying a higher multiple without matching revenue growth.
The risk is that the company is committing to large infrastructure obligations before the durability of demand, margins and capacity use are fully visible. If customers keep buying Claude at the current pace, the infrastructure could support a larger business. If growth slows or AI progress stalls, the same commitments could become a major exposure.

Background
Anthropic’s valuation path has accelerated sharply since March 2025, when the company was valued at $61.5 billion. By February 2026, the source material says Anthropic had raised a $30 billion Series G at a $380 billion post-money valuation and reported $14 billion in run-rate revenue.
By May 2026, Anthropic said run-rate revenue had reached $47 billion. The source material compares that pace with traditional enterprise software companies, noting that Salesforce took roughly two decades to reach revenue levels Anthropic has now passed.
The company’s distribution also matters. The source material says Claude is available across Amazon, Google and Microsoft’s cloud platforms. That reach may help explain investor willingness to fund capacity ahead of demand, though the economics of cloud-reseller revenue and pass-through costs remain a key question.

What Remains Unclear
Several details remain unclear from the provided material. The exact investor list, the full contractual terms of the compute commitments, the timing of capacity delivery and the margin profile of Anthropic’s reported run-rate revenue are not fully detailed.
It is also unclear how much of the reported revenue reflects direct customer demand versus cloud-reseller pass-throughs. The source material says revenue is reported gross of cloud-reseller pass-throughs, which may make the top-line figure less comparable with older software companies.
