Both companies sell flash-based storage products used in computers and data centers, so they go after the same buyers for SSDs and other memory storage needs. Micron sells DRAM, NAND and SSDs, while SanDisk sells flash-based storage into Cloud, Client and Consumer markets, including enterprise SSDs for data centers. That puts them in direct competition for storage budgets from cloud and device makers.

Micron Drops 13% as AI Chip Trade Gets Hit Ahead of Big Earnings Test

As of Jun 23, 2026

For informational purposes only.

Summary

Micron dropped about 13% today to roughly $1,052, a sharp hit that mainly reflects a global shakeout in hot AI chip stocks and sky-high expectations ahead of tomorrow’s earnings, not a sudden crack in the company’s business. A 10% plunge in South Korea’s chip-heavy market, rising bearish bets on the semiconductor sector, and worries about overextended AI valuations all combined to knock memory names lower, with Micron caught in the crossfire. At the same time, Micron is heading into a “prove it” moment: after an enormous run and aggressive analyst targets, even strong results could disappoint if guidance doesn’t reinforce the AI memory boom narrative. For you, this means Micron has entered a high-volatility phase where day-to-day swings are large, and the upcoming earnings report will go a long way toward deciding whether today was just a painful breather or the start of a deeper reset.

If you follow Micron, today probably felt rough: the stock dropped about 13% in a single session. Let’s walk through what actually happened, why it happened, and what’s worth watching next, in plain English.

What actually happened today

Micron closed around $1,052, down roughly 13% from yesterday. That’s a big one‑day hit, especially after such a huge run this year. Trading volume was only a bit above normal, which suggests this was a sharp re‑pricing rather than full‑on panic with record volume.

Even after today’s drop, Micron is still up almost 200% over the last two months and far more over the past year. So the stock went from “straight up” to “hard pullback,” but not from “winner” to “disaster.”

Why it fell: three main forces

1. A global chip and AI sell‑off, triggered in Korea.
South Korea’s market plunged about 10% today, led by Micron’s closest memory rivals, Samsung and SK Hynix. There were warnings about leveraged ETFs (funds that borrow to amplify moves) tied to those stocks. That spooked investors worldwide.

Because Micron sells the same kind of memory chips, the fear spread: if Korean chip stocks are tumbling, maybe the whole “AI memory boom” trade has gotten too crowded. News also flagged that semiconductor ETFs dropped nearly 7% just a day after record highs, and traders started making more “downside bets” on chip stocks. Micron was pulled into that wave.
