Micron Technology ($MU ) went public on June 1, 1984, opening around a split-adjusted $1.35. Fast-forward to October 2, 2026, and the stock closed at about $1,074.89—a huge long-term move.
The really explosive phase came recently. In April 2025, MU was trading around $61–$90. By October 2025, it had climbed as high asabout $232, and by May 2026 it accelerated from roughly $510 to nearly $981. It then reached an intraday high of about $1,255 on June 25, 2026.
In simple terms: MU went from a split-adjusted $1.35 IPO price in 1984 to roughly $1,075 today, with the latest monster rally driven in part by Micron's position in the booming AI-memory market.
The interesting part isn't just the number. It's the acceleration.
Old semiconductor company. New AI economy. Same ticker. Very different scale.
