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 being framed not only as a valuation milestone, but as a bet on compute capacity, with Micron, Samsung and SK hynix named as strategic infrastructure partners.
Anthropic said on May 28, 2026, that it closed a $65 billion Series H financing at a $965 billion post-money valuation, a round that Thorsten Meyer AI described as the largest private financing in history and a major bet on AI compute capacity.
The financing puts Anthropic close to a $1 trillion private-market valuation. According to the source material, the new valuation would move Anthropic ahead of OpenAI’s reported $852 billion valuation in March 2026 and make it the most valuable private company.
The source material says 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. It also reports that Anthropic reached $47 billion in run-rate revenue as of May 2026, up from $14 billion in February 2026.
The key detail in the announcement is the infrastructure plan. Anthropic named Micron, Samsung and SK hynix as strategic infrastructure partners and itemized more than 10 gigawatts of compute commitments. The source frames the round as a capacity financing tied to chip supply, cloud access and data center buildout, rather than only a capital raise.
Why It Matters
The financing matters because frontier AI development is becoming tied to physical infrastructure: chips, memory, power and cloud capacity. If Anthropic can turn the committed compute into paid usage, the round could support faster model training, broader enterprise deployment and a larger share of AI spending.
The valuation also changes the comparison set for private AI companies. The source material says Anthropic’s revenue grew faster than its valuation between its February 2026 Series G and May 2026 Series H, compressing the revenue multiple from about 27 times to about 20.5 times. That does not make the valuation low by software-market standards, but it complicates a simple bubble narrative.

Background
Anthropic’s previous Series G, according to the source material, valued the company at $380 billion in February 2026 after a $30 billion raise. Three months later, the Series H more than doubled that valuation while reported run-rate revenue rose from $14 billion to $47 billion.
The source also points to Anthropic’s cloud distribution as part of the investment case, saying Claude is available across the three major cloud platforms. It says enterprise AI spend share rose from about 10 percent to more than 65 percent in a year, though those figures are attributed to the source material and were not independently verified here.

What Remains Unclear
Several details remain unclear. The source material does not specify the full investor list, the exact economics of the compute commitments, how much of reported revenue reflects cloud-reseller pass-throughs, or when Anthropic expects to reach profitability. It is also not yet clear how quickly the more than 10 gigawatts of committed capacity will come online or how much paying demand will be available when it does.

Key Questions
What did Anthropic announce?
Anthropic said it closed a $65 billion Series H financing at a $965 billion post-money valuation on May 28, 2026.
Why are Micron, Samsung and SK hynix part of the story?
The source material says Anthropic named the three memory chipmakers as strategic infrastructure partners, pointing to chip supply and compute capacity as core constraints for the company’s growth plan.
Is the $965 billion valuation confirmed?
The valuation is reported in the source material as part of Anthropic’s May 28, 2026 announcement. This article treats the figure as attributed to that announcement and source material.
Why does the revenue multiple matter?
The source says Anthropic’s run-rate revenue grew from $14 billion in February 2026 to $47 billion in May 2026, while valuation rose from $380 billion to $965 billion. That would mean the revenue multiple fell from about 27 times to about 20.5 times.
What remains unclear?
The major open questions are profitability, the economics of reseller revenue, the timing of compute delivery and whether demand will fill the planned capacity.
