Micron Technology shares, buoyed by an AI-driven rally, extended gains on Thursday and were at one point near 20% higher, briefly overtaking Meta Platforms and Tesla in market capitalization. Gains later narrowed to about 10%, leaving Micron’s market value around $1.3 trillion. The move followed Wednesday after-hours guidance for Q4 revenue and profit that helped reverse recent losses. Micron said customers have committed about $22 bln to secure memory-chip supply.
