Micron Stock Jumps 5% on Anthropic AI Deal Ahead of Earnings

Micron Technology (MU) shares climbed nearly 5% on Monday after the memory maker unveiled a strategic deal with Anthropic covering chip design, long-term supply, and an equity investment in the AI lab.

The announcement landed two days before Micron reports fiscal third-quarter results, sharpening investor focus on how AI memory demand is feeding the company’s growth.

Inside the Micron and Anthropic deal

Micron announced the partnership on Monday. It frames the tie-up as a bridge between frontier AI models and the design of memory hardware. The two firms will co-engineer memory and storage subsystems tuned for AI training and inference.

The deal also locks in a multi-year supply arrangement across Micron’s data center portfolio. It covers high-bandwidth memory, DRAM, and solid-state drives.

That gives Anthropic committed components as Claude usage keeps growing.

The supply guarantee carries weight given Anthropic’s scale. The lab’s run-rate revenue crossed $47 billion in May, and its latest raise valued it at $965 billion. Securing memory now hedges against a market where AI chips are scarce.

Micron also took a strategic stake in Anthropic’s Series H round. It joined Samsung and SK hynix, the world’s other leading memory makers, as named infrastructure backers of Anthropic.

Inside its own walls, Micron uses Claude to accelerate engineering and coding work.

“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… As demand for Claude grows, this is how we scale our compute for the long term,” read an excerpt in the announcement, citing Tom Brown, co-founder and chief compute officer at Anthropic.

MU Stock Climbs Ahead of Earnings

Micron’s MU shares rose nearly 5% intraday, extending a rally built on booming AI memory demand.

Micron set an all-time high above $1,130 on June 18, and the stock has more than tripled in 2026. It now trades above that record at $1,192, ahead of Wednesday’s earnings release, capping a busy reporting week.

The timing matters because memory pricing has tightened sharply. Deutsche Bank’s Melissa Weathers raised her price target to $1,500 from $1,000 on June 17.

TD Cowen’s Krish Sankar matched that figure, citing a projected 2027 earnings per share of roughly $150.

Both analysts expect the memory shortage to run well into 2028.

Still, not every desk sees Micron as the cleanest AI bet. Some Wall Street strategists have favored Nvidia over Micron, pointing to steadier exposure to AI infrastructure spending.

Wednesday’s report will test whether the Anthropic deal signals a lasting demand pipeline or a well-timed headline.

With memory in short supply and prices climbing, Micron’s guidance may reveal more about 2027 than the quarter just ended.
