Micron signs supply agreement with Anthropic AI, invests in Series H round

Micron Technology announced a sweeping strategic partnership with Anthropic on June 22, 2026, combining a multi-year supply agreement with a co-design relationship on memory and storage architecture for AI data centers.

Micron also made an undisclosed strategic investment in Anthropic’s Series H funding round, joining investors including Samsung, SK hynix, Altimeter Capital, Sequoia, and Amazon.

What the deal actually covers

The partnership has two major pillars. First, Micron will supply Anthropic with its core data center products: high-bandwidth memory (HBM), DRAM, and solid-state drives (SSDs). The second pillar is a collaborative design relationship. Micron and Anthropic will work together on memory and storage architecture specifically optimized for AI workloads.

Sumit Sadana, Micron’s EVP, framed the collaboration as an effort to innovate AI infrastructure.

On Anthropic’s side, the deal includes enterprise-level deployment of Claude, the company’s flagship AI model family, across Micron’s operations.

The Series H context

Anthropic’s Series H round closed on May 28, 2026, raising $65 billion at a post-money valuation of $965 billion.

The investor list for the round includes Samsung and SK hynix, two of Micron’s direct competitors in the memory chip market, as well as Altimeter Capital, Sequoia, and Amazon. Micron’s investment terms remain undisclosed.
