Micron Technology (MU) closed Monday at $1,192, up roughly 6%, after the memory chipmaker announced a multi-year supply and strategic partnership deal with Anthropic.
The agreement covers Micron’s full data center portfolio — high-bandwidth memory (HBM), DRAM, and solid-state drives — to support Anthropic’s growing compute demands as usage of its Claude models scales up.
Micron also made a strategic investment in Anthropic’s Series H funding round. Neither the investment amount nor the supply deal’s financial terms were disclosed.
The two companies will work together to analyze how memory and storage systems perform across AI workloads and how they fit within the broader infrastructure stack.
“Our compute strategy depends on getting every layer of the stack right, and memory and storage are central to how efficiently we can train and serve Claude,” said Tom Brown, Anthropic’s co-founder and chief compute officer.
Micron said it has already deployed Claude models across its own operations — applying them to coding and agentic use cases in engineering, manufacturing, and enterprise functions. It expects to expand those deployments going forward.
That internal usage adds a layer to the deal beyond a simple vendor relationship. Micron is both a supplier to Anthropic and now a customer of its AI products.
MU stock is up more than 300% year to date, according to Yahoo Finance, making Monday’s record close the latest milestone in a strong run for the chipmaker.
Anthropic has been moving quickly to lock in compute capacity across multiple fronts. The Micron deal follows earlier arrangements with Amazon Web Services, Google, CoreWeave, Broadcom, and SpaceX.
Anthropic was also reported to be in early talks to use Microsoft’s custom Maia 200 AI chips, part of a broader effort to diversify its chip and infrastructure partnerships.
On June 1, Anthropic confidentially filed for a U.S. IPO. Its Series H closed at a $965 billion valuation after raising $65 billion in that round.
The Micron deal adds memory and storage supply certainty to Anthropic’s infrastructure stack as it prepares for a potential public listing.
