# QUICK SPARK: Micron Reclaims $1 Trillion Valuation on Broad AI Stock Rally

**Micron Technology Inc.** (NASDAQ:MU) rose over 7% on Wednesday to $932.46, lifting its market value to $1.04 trillion, the 15th largest in the world.

Three things moved it. 

First, Singapore’s state fund Temasek is reported to be planning stakes in **Samsung** **Electronics Co. Ltd.** (OTC:SSNLF) and SK **Hynix** **Inc.** (NASDAQ:SKHY). 

Second, strong earnings from AI infrastructure players. **CoreWeave Inc.** (NASDAQ:CRWV) raised its 2026 capital spending plan to as much as $39 billion and rose 18%. **Lumentum Holdings Inc.** (NASDAQ:LITE) more than doubled revenue to $1.01 billion.

Both say the same thing. The data center buildout is getting bigger, not smaller. 

Last but not least, **Intel Corp.**‘s (NASDAQ:INTC) chief executive said memory makers are sold out for two years.

The **Roundhill Memory ETF** (CBOE: DRAM) jumped 7.7%.
