Micron lifts U.S. spending to $250 billion

Micron has announced that its planned U.S. semiconductor supply chain investment will rise to over $250 billion through 2035, up from $200 billion. A key component of this investment includes a $500 m... Read original →

Micron’s $250B U.S. investment surge targets a critical chokepoint: 300mm silicon wafers. This triggers a technical cascade—upstream suppliers like GlobalWafers must accelerate yield ramp and equipment deployment, while downstream DRAM/NAND scaling hinges on wafer purity and defect control; any supply lag directly throttles AI chip output. CHIPS Act subsidies ease capex but impose costly compliance burdens, including sensitive data disclosure and China investment curbs, amplifying operational and geopolitical risk. Rivals like Samsung and SK Hynix will likely counter with long-term wafer deals or push domestic Korean wafer fabs. Over the next 12–24 months, global 300mm wafer capacity will concentrate further, boosting pricing power for Japan and Taiwan, China-based players. Despite U.S. fab announcements, true supply chain autonomy remains illusory—structural shortages may persist into 2027.
