TL;DR
Anthropic said on May 28, 2026, that it closed a $65 billion Series H at a $965 billion post-money valuation. The raise is being read not only as a funding milestone, but as a large-scale compute capacity bet tied to more than 10 gigawatts of commitments and chip partners including Micron, Samsung and SK hynix.
Anthropic said Thursday, May 28, 2026, that it closed a $65 billion Series H financing at a $965 billion post-money valuation, a raise that the company’s announcement links to large compute commitments and strategic infrastructure partnerships with Micron, Samsung and SK hynix.
The financing would make Anthropic the most valuable private company in the source material’s account, ahead of OpenAI’s reported March 2026 valuation of $852 billion. The round follows a rapid rise from a $61.5 billion valuation in March 2025 to $965 billion in May 2026.
Thorsten Meyer AI’s analysis says Anthropic reported $47 billion in run-rate revenue as of May 2026, up from $14 billion in February. On those figures, the company’s revenue multiple fell from about 27 times at its Series G to about 20.5 times at Series H, even as the valuation rose sharply.
The announcement’s central operational detail is compute. According to the source material, Anthropic identified more than 10 gigawatts of committed capacity and more than $200 billion in announced compute spend across multi-year contracts. The analysis frames the financing as a capacity round, not only a valuation round.
Why It Matters
The raise matters because it points to the scale of capital now required to compete at the frontier of artificial intelligence. Anthropic’s reported revenue growth suggests strong demand, but the financing also shows that serving that demand may depend on access to power, data centers, GPUs, memory chips and cloud partners.
The naming of Micron, Samsung and SK hynix matters because those companies sit closer to the physical supply chain than a typical software funding announcement. If compute supply is the limiting factor, Anthropic’s ability to secure memory and infrastructure could affect how quickly it can serve enterprise customers and train or run future models.

Background
Anthropic’s valuation has risen in a compressed period: $61.5 billion in March 2025, $380 billion after its Series G in February 2026, and $965 billion after the Series H in May 2026, according to the source material. The company’s reported run-rate revenue rose from $14 billion in February 2026 to $47 billion in May 2026.
The analysis contrasts that pattern with typical bubble concerns. The valuation increased, but the reported revenue base grew faster over the same short period, which lowered the implied revenue multiple. That does not make the valuation low by historical software standards, but it changes the nature of the debate from simple price inflation to whether the revenue and capacity assumptions can hold.

What Remains Unclear
Several points remain unclear. The source material does not provide full investor terms, dilution, profitability data, cash burn, contract-level revenue detail or the exact timing for all compute capacity to come online. It is also unclear how much of the reported run-rate revenue reflects direct end-customer demand versus cloud-reseller pass-through revenue.
The main open question is whether Anthropic can convert the committed compute into durable paid usage at high enough margins. The source frames the next 18 to 24 months as the period when capacity comes online and the bet is tested.

What’s Next
Investors, customers and competitors will watch whether Anthropic can bring the promised compute capacity online, fill it with paying demand and move toward profitability. The next milestones are likely to include infrastructure buildout updates, cloud distribution performance, enterprise adoption data and any disclosure on margins or cash burn.

Key Questions
What did Anthropic announce?
Anthropic announced a $65 billion Series H financing at a $965 billion post-money valuation on May 28, 2026, according to the source material.
Why is the round being described as a compute bet?
The announcement ties the financing to more than 10 gigawatts of compute commitments and names Micron, Samsung and SK hynix as strategic infrastructure partners. That points to capacity, chips and power as central constraints.
Is the valuation clearly supported by revenue?
The source says Anthropic reached $47 billion in run-rate revenue as of May 2026, which would lower its implied revenue multiple from February. Still, 20.5 times revenue remains high by historical software standards, and profitability details are not confirmed in the source material.
What remains unknown?
Unknowns include exact financing terms, margins, cash burn, how revenue is counted, and whether future compute capacity will be fully used by paying customers.
