Micron bets $250B on U.S. chips to feed the AI memory boom

Micron is going big on American silicon. The memory giant just bumped its U.S. investment plan to more than $250 billion through 2035 — a ~$50B jump from last year's $200B commitment, which itself was up from $170B originally. The driver? AI's insatiable appetite for memory.

The goal is to make 40% of Micron's DRAM in the U.S., up from a sliver today. The centerpiece is a mega-campus near Syracuse, New York — pegged as the largest semiconductor site in U.S. history, with up to four fabs and ~50,000 projected jobs. Micron just poured first concrete in Clay, NY, more than a quarter ahead of schedule. Another $3 billion goes to shoring up the domestic supply chain, including $500M for GlobalWafers' silicon-wafer plant in Sherman, Texas.

HBM — the stacked memory that sits next to Nvidia GPUs — is the hot commodity here, and Micron wants it made at home rather than shipped from Asia.

Why it matters: AI compute is only as fast as the memory feeding it, and Micron is spending a quarter-trillion dollars to make sure that memory is made in America.
