# Why Micron (MU) rose 3.53% on October 23, 2026

Micron (MU) rose 3.53% on October 23, 2026 — SK Hynix scrapping Solidigm IPO tightens memory.

## What happened

SK Hynix scrapped its planned IPO of Solidigm, its NAND and SSD unit, according to LYNX, and Micron and Sandisk rose on the news.

## Why it moved

Investors price memory names on supply discipline, and a shelved IPO removes a potential source of added NAND capacity and financing.

## Why it matters

This sits inside the AI Memory theme, where HBM and high-capacity storage demand from AI datacenters is the core driver.

## What would break the thesis

If SK Hynix revives the Solidigm listing quickly, or the market concludes the removed supply was immaterial, the move will fade. A broad NAND price correction would also override any sentiment benefit.
