# Why Western Digital (WDC) rose 4.32% on August 12, 2026

Western Digital (WDC) rose 4.32% on August 12, 2026 — CoreWeave's old-chip reuse story boosts memory demand.

## What happened

CoreWeave's announcement that it is profitably deploying older Nvidia H100s and A100s for inference workloads triggered a broad AI Memory rally, lifting Western Digital alongside memory and interconnect peers.

## Why it moved

Inference-tier GPU demand from CoreWeave and similar providers broadens the addressable market for storage and NAND — older chips running longer inference jobs require sustained capacity, offsetting fears that capex…

## Why it matters

The AI Memory theme is moving from 'who builds the newest chips fastest' to 'who supplies the silicon ecosystem at every tier' — storage and connectivity now matter as much as edge compute, extending the cycle.

## What would break the thesis

If inference workloads plateau or hyperscalers consolidate to in-house silicon, Western Digital's legacy NAND demand could erode faster than new AI-driven growth can compensate.
