# Why SanDisk (SNDK) rose 6.26% on August 12, 2026

SanDisk (SNDK) rose 6.26% on August 12, 2026 — Apple's CXMT memory tests spark memory rally.

## What happened

Apple is testing CXMT Chinese memory chips for iPhones and MacBooks, a potential sign of memory-supply diversification away from incumbents.

## Why it moved

The Apple-CXMT story is a headwind to SanDisk's device-memory margin expectations; however, SanDisk is rising on the broader AI Memory rally, as Micron's (parent company Crucial's) DRAM and NAND demand surge from data…

## Why it matters

SanDisk is riding the AI Memory supercycle — enterprise and hyperscaler memory procurement is accelerating faster than device-side softness, creating a favorable demand mix.

## What would break the thesis

If Apple's CXMT tests succeed and scale production, SanDisk loses device-customer wallet share; or if AI capex moderates faster than expected, the memory-demand tailwind evaporates.
