Micron raises U.S. capex to $250B through 2035 with GlobalWafers $500M financing

Micron announced it will raise its planned U.S. investment to $250 billion through 2035, roughly a $50 billion increase, as memory demand from the artificial intelligence buildout skyrockets. The investment includes $500 million for Taiwanese-headquartered GlobalWafers to expand its wafer development and manufacturing in its Texas facilities, and comes with a 10-year supply agreement for raw silicon wafer capacity.

Micron's stock rose 7% on the announcement. Other chip-supply names rallied in tandem: Applied Materials, KLA Corp and Lam Research each gained 7%, while ARM Holdings jumped 11%.

GlobalWafers is currently the only supplier participating in the CHIPS for America Program capable of producing advanced 300mm raw silicon wafers within the United States, making Micron's partnership a supply-chain resilience play.

For architects and infrastructure teams, this signals Micron's multi-decade confidence in AI memory demand and highlights upstream wafer capacity as a critical bottleneck. Securing long-term raw material supply is now a strategic equity and cost decision, not just a procurement line item.
