Memory stocks got hit by an AI spending scare

The selloff came for the memory aisle

Western Digital woke up on the wrong side of Monday, dropping about 6% in premarket trading as investors hit the “less risk, please” button across growth tech. The bigger mood swing started with weaker Nasdaq futures, but the real action was in memory and storage stocks, where the whole group got treated like it had cooties.

Micron, Sandisk, SK hynix, and Seagate all joined the ride lower. When a whole corner of the chip market moves together, that’s usually a sign the market isn’t just pricing one company — it’s pricing a story.

The story: AI spending might not be a straight line

The catalyst here was a fresh dose of skepticism around AI infrastructure spending. The Financial Times reported that calls to slow AI development over safety concerns have raised questions about future capital spending. Translation: if data-center budgets get trimmed, memory and storage demand can get messy fast.

That’s a big deal for Western Digital because these businesses are basically tethered to the buildout of AI-heavy data centers. If the industry decides to hit pause on spending, the stocks that sell the picks and shovels can feel it first.

Why investors care

• Western Digital fell about 6% in premarket trading to roughly $420.35.
• It was not alone — Micron, Sandisk, SK hynix, and Seagate all got dragged into the same trade.
• The market is still willing to reward AI infrastructure names, but apparently only when the story sounds like a straight shot up and to the right. Spoiler: it usually isn’t.

Big picture: this looks less like a Western Digital problem and more like the market briefly remembering that AI spending is still spending, and spending can always get cut.
