Micron shares launched higher Wednesday after management confirmed that demand for AI memory has blown straight past supply, and there’s no sign of that imbalance easing anytime soon.

Micron beat fiscal first-quarter expectations and then proceeded to blow a hole straight through consensus for the quarter ahead. The message from management was borderline absurd: AI memory demand is running so hot that supply doesn’t even pretend to keep up anymore.

“We are more than sold out,” said business chief Sumit Sadana on the earnings call. Not nearly sold out. Not strong demand. Fully, unapologetically sold out… with unmet demand baked into internal models for the foreseeable future. That’s about as much leverage as you can get.

Looking at the numbers, Micron reported adjusted earnings of $4.78 per share on $13.64 billion in revenue, comfortably ahead of expectations. But the real shock came from guidance. The company expects revenue to jump to roughly $18.7 billion next quarter, miles above the $14.2 billion analysts were modeling. Adjusted earnings are projected at $8.42 per share… nearly double what Wall Street had penciled in.

That kind of delta doesn’t happen often in semiconductors. Morgan Stanley called it the largest revenue and net income upside surprise in U.S. semiconductor history outside of Nvidia. A pretty big compliment.

The driver here is high-bandwidth memory… the kind that sits next to AI accelerators and keeps models fed with data at insane speeds. Micron now expects the total addressable market for HBM to reach $100 billion by 2028, growing at a 40% compounded annual rate.

To keep up, Micron raised capital expenditure guidance to $20 billion from $18 billion. That would normally scare investors. This time, it did the opposite. The market isn’t worried about overspending. It’s worried about under-supplying.

Banks responded accordingly. JPMorgan raised its price target, citing a favorable pricing environment. Bank of America upgraded the stock to a buy. The theme across notes was the same: memory is no longer the forgotten cousin of AI hardware. It’s the bottleneck.

And that’s the bigger takeaway.

While investors have spent the last year obsessing over GPUs and cloud providers, Micron’s report was a reminder that AI doesn’t run on silicon alone. It runs on memory (lots of it) and right now, that part of the stack is tight.

If Nvidia sells the engines, Micron sells the fuel. And for the moment, the pumps are empty.

That doesn’t mean risk has vanished. Semiconductor cycles still exist. Capital spending still cuts both ways. But with investors more focused on who has pricing power versus who has balance-sheet stress, Micron just made its case very clearly.

Some companies are struggling to finance the AI build-out. Others are struggling to keep up with it. And Micron wants everyone to know they’re firmly in the second camp.
