TL;DR
Anthropic announced on May 28, 2026, that it closed a $65 billion Series H round at a $965 billion post-money valuation. The company said the financing is tied to major compute commitments and named Micron, Samsung and SK hynix as strategic infrastructure partners, making the round as much about capacity as capital.
Anthropic announced Thursday that it has closed a $65 billion Series H round at a $965 billion post-money valuation, a financing that the company framed around large compute commitments and new chip-supply partners as demand for frontier AI systems strains infrastructure capacity.

The round, described in the source material as the largest private financing in history, would put Anthropic ahead of 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 over roughly 14 months.
The company also reported $47 billion in run-rate revenue as of May 2026, up from $14 billion in February 2026. Based on those figures, its revenue multiple fell from about 27 times at its Series G to about 20.5 times at its Series H, even as the valuation rose sharply.
The middle of the announcement appears to carry the main signal: Anthropic named Micron, Samsung and SK hynix as strategic infrastructure partners and itemized more than 10 gigawatts of compute commitments. The source material says Anthropic has more than $200 billion in announced compute spend across multi-year contracts.
Why It Matters
The financing matters because it shows how frontier AI companies are being valued around their ability to secure compute, memory and power capacity, not only software revenue. If Anthropic can fill that capacity with paying demand, the round could support a much larger enterprise AI business. If it cannot, the commitments could become a large fixed exposure.
The reported valuation is high by historic software standards, but the revenue growth changes the comparison. The company’s reported run-rate revenue increased faster than its valuation between February and May 2026, which is why the revenue multiple compressed rather than expanded.

Background
Anthropic’s Series H follows a Series G in February 2026 that reportedly valued the company at $380 billion after a $30 billion raise. In March 2025, the company was valued at $61.5 billion. The source material compares the speed of Anthropic’s revenue growth with Salesforce’s much longer path to similar revenue scale.
The infrastructure list also marks a shift in emphasis. The announcement still includes major cloud and AI infrastructure names, including Amazon, Google, Broadcom, Microsoft, Nvidia, SpaceX and Fluidstack. But the addition of memory chipmakers points to supply constraints in chips and power as a central issue for AI deployment.

What Remains Unclear
It is not yet clear how much of the $47 billion run-rate revenue is net revenue versus cloud-reseller pass-through revenue. Profitability remains unresolved in the source material, which says it is still about two years out. It is also unclear how quickly the promised compute capacity will come online, what pricing Anthropic has locked in, and how much paying demand will be available when that capacity arrives.
What’s Next
The next test is execution over the next 18 to 24 months, as the committed gigawatts of compute capacity are expected to come online. Investors and customers will be watching whether Anthropic can convert infrastructure access into durable enterprise revenue, improved margins and a path to profitability.
