TL;DR
Anthropic said on May 28, 2026, that it raised $65 billion in Series H funding at a $965 billion post-money valuation. The company said the money will expand compute for Claude, with infrastructure partners including Micron, Samsung and SK hynix; the scale, costs and timing of that buildout remain open.
Anthropic said it raised $65 billion in Series H funding at a $965 billion post-money valuation, a financing that makes the Claude maker one of the world’s most valuable private technology companies and puts compute capacity at the center of the next phase of the AI race.
In its May 28 announcement, Anthropic said the round was led by Altimeter Capital, Dragoneer, Greenoaks and Sequoia Capital, with Capital Group, Coatue, D1 Capital Partners, GIC, ICONIQ and XN among the co-leads. The company said its run-rate revenue crossed $47 billion earlier in May, a figure it tied to rising enterprise use of Claude.
The company said the funding is expected to support safety and interpretability research, product expansion and compute growth. The round includes $15 billion of previously committed hyperscaler investments, including $5 billion from Amazon, according to Anthropic.
The compute piece is the core development. Anthropic named Micron, Samsung and SK hynix as strategic infrastructure partners and said it had signed agreements with Amazon for up to five gigawatts of new capacity, with Google and Broadcom for five gigawatts of next-generation TPU capacity, and with SpaceX for access to GPU capacity in Colossus 1 and Colossus 2.
Why It Matters
The round matters because it is not only a valuation story. Frontier AI companies are now competing for memory, advanced chips, cloud contracts, data center capacity and power at a scale that can shape suppliers, utilities, cloud providers and public markets.
For Anthropic, the financing could help reduce capacity bottlenecks as Claude use grows. For rivals and investors, it signals that the cost of staying near the front of the AI model race may require infrastructure spending closer to energy and semiconductor projects than to older software funding rounds.

Background
Anthropic was founded in 2021 by former OpenAI employees and has become one of the main competitors in generative AI. AP reported that the round puts Anthropic ahead of OpenAI in reported market value and revenue, while Reuters reported that OpenAI was last valued at $852 billion post-money in March.
The supplied Thorsten Meyer AI analysis frames the financing as a capacity round, not a standard software valuation milestone. That reading is supported by Anthropic’s own emphasis on memory, logic chips, hyperscaler commitments and power-linked data center capacity, though Anthropic has not disclosed a full capital spending schedule.

What Remains Unclear
Several details remain unclear. Anthropic has not disclosed the round’s full terms, ownership dilution, cash burn, profitability timeline, gross margin profile, or how much of the $47 billion run-rate revenue is net of cloud-reseller pass-throughs.
It is also not yet clear how fast the named compute capacity will come online, how much it will cost to operate, or whether demand will stay high enough to fill that capacity once it is available.

What’s Next
The next milestones are execution on the Amazon, Google, Broadcom and SpaceX capacity agreements, further disclosures on revenue quality and margins, and any public listing filings if Anthropic moves toward an IPO. Investors will be watching whether the added compute turns into durable paid usage rather than unused capacity.

Key Questions
What did Anthropic announce?
Anthropic said it raised $65 billion in Series H funding at a $965 billion post-money valuation on May 28, 2026.
Why is the round being viewed as a compute story?
Anthropic tied the financing to compute expansion and named Micron, Samsung, SK hynix, Amazon, Google, Broadcom and SpaceX in connection with chips, memory, TPUs, GPUs and data center capacity.
Is the $965 billion valuation confirmed?
Yes. Anthropic stated the $965 billion post-money valuation in its own announcement. Comparisons with OpenAI depend on reported private-market figures, which vary by source.
What remains unknown?
The company has not provided full economics for the round, detailed profitability targets, exact spending schedules, or a clear breakdown of revenue quality. Those gaps will shape how investors judge the financing.
