SanDisk (SNDK) rose 4.04% on August 21, 2026 — Primemas nears CXL memory production with Micron.

## What happened

SanDisk moved with the broader AI Memory theme as Primemas announced it is nearing CXL memory mass production with Micron, lifting sentiment across NAND and memory suppliers.

## Why it moved

CXL memory infrastructure adoption signals sustained and expanding AI server demand, pulling through incremental flash storage for caching and system design; as a flash memory leader, SanDisk participates in the broader…

The AI Memory supercycle has driven HBM and DRAM pricing surges for three months on AI server data-bottleneck pressure, but the move is stalling as supply additions near completion and hyperscalers optimize memory…

## What would break the thesis

If CXL adoption lags expectations or hyperscalers prioritize in-house memory optimization over incremental capacity purchases, demand growth flattens and memory pricing stabilizes or declines.
