Micron just found out what happens when a commodity gets priced like software

Micron’s latest numbers look almost broken.

Revenue jumped from $9.3 billion to $41.46 billion in one year.

Cost of revenue went from $5.79 billion to $6.40 billion.

Revenue more than quadrupled.

The cost line barely moved.

That produced an 84.6% gross margin.

Micron’s previous record in the 68 quarters on record was only 58.87%.

Then there is the really strange part.

In fiscal 2023, the same business had a negative gross margin.

This is what makes memory so different from most businesses.

When supply is tight, Micron doesn’t suddenly need four times as many factories, workers and machines to sell four times as much memory.

The factories already exist.

The capacity was committed years earlier.

So when the selling price explodes, the extra revenue can fall through to the bottom line at a ridiculous rate.

For one quarter, a commodity manufacturer starts looking like a software company.

But there is a trap hidden inside that.

That profit is also the signal telling the industry to build more capacity.

Micron generated $18.3 billion of adjusted free cash flow in the quarter and spent $7.1 billion on net capex. It expects roughly $27 billion of capital spending for fiscal 2026.

So the same pricing explosion creating those insane margins is also creating the cash to attack the shortage.

That is why I don’t think the first question should be:

“Can Micron keep an 85% margin?”

The better question is:

How long can demand grow faster than the industry’s ability to spend that money back into supply?

And AI makes this cycle stranger.

HBM is consuming enormous amounts of manufacturing capacity, while hyperscalers are signing long-term supply deals. Reuters reported this week that smaller phone and laptop makers are already preparing for memory shortages extending through at least 2027.

So maybe this time the old memory cycle takes longer to break.

But if the industry eventually catches up, the math can reverse just as violently.

That’s the part people should watch.

84% gross margins don’t just tell you Micron is making a fortune.

They tell you the economic incentive to destroy those margins has probably never been higher.
