Who's involved
- Micron
- An American company that makes memory chips, the parts that hold data inside computers and phones.
- It reported record sales on September 30 and expects even more next quarter.
- Sanjay Mehrotra
- Micron's chairman and chief executive.
- Mehrotra runs Micron and told investors to expect "an even stronger fiscal 2027."
- Apple
- The company that makes the iPhone, iPad and Mac.
- In June it raised prices on some MacBooks and iPads by up to $300, blaming memory costs.
- Nvidia
- A company that makes the chips AI data centers run on.
- Its AI chips need high-bandwidth memory, and Micron says it is working with Nvidia on a custom version.
What changed
If you have priced a MacBook or iPad since June, you have met this story at the checkout. The memory shortage behind Apple's higher prices just gave Micron, an American maker of memory chips, its best year. Is that shortage over? Not by Micron's numbers. Its sales for the three months that ended September 3 were $54.23 billion, nearly five times the $11.32 billion of a year earlier. Micron expects about $61.5 billion next quarter.
On June 25, Apple, the company behind the iPhone, iPad and Mac, raised prices on some MacBooks and iPads by up to $300. A 512GB MacBook Air went to $1,299 from $1,099. An iPad Air with 128GB went to $749 from $599.
Apple said why in plain words: "We have never seen a component price increase this much, this quickly." The components are memory and storage chips. AI data centers need huge amounts of them, and the AI chips inside those data centers, from companies like Nvidia, need a stacked kind called high-bandwidth memory. The world's leading makers cannot build enough of it.
What's at Stake
Micron's sales for the three months that ended September 3, nearly five times a year earlier.
Market intelligence
The read: Over five years, Micron is up 1445.8%, Apple is up 131.6% and Nvidia is up 1013.0%. Over one year, Micron is up 484.2%, Apple is up 28.0% and Nvidia is up 23.0%. Over the past month, Micron is up, Apple is up and Nvidia is up. Micron is up 3.0%, Apple is down 0.8% and Nvidia is up 1.1% today, while the Nasdaq is flat.

Then and Now
How We Got Here
- Micron's spring quarter ends
Sales for the three months reach $41.46 billion.
- Apple raises prices
Some MacBooks and iPads go up by as much as $300, and Apple blames memory and storage chip costs.
- Micron's summer quarter ends
Sales for the three months reach $54.23 billion, nearly five times a year earlier.
- Micron reports
It reports record results and forecasts about $61.5 billion for the next quarter.
The System Underneath
AI data centers want more memory than makers can build, which pushes up memory prices, which costs you more for a MacBook and hands Micron a record quarter.
The People

One shortage, two results: a record year for Micron, and higher prices on everyday tech like laptops.
Why it matters
For Micron, the shortage shows up as profit. Last quarter it kept about 87 cents of each sales dollar after the cost of making its chips, up from less than half a year earlier. Its profit for the quarter was $37.7 billion, against $3.2 billion a year before.
The biggest jump came from data centers. Micron's Core Data Center unit sold about eleven times as much in the quarter as a year earlier. Investors have noticed: Micron's stock market value has topped $1.2 trillion.
That matters if you are shopping for a laptop or tablet. Apple said it had shielded customers from these increases so far, but had reached a point where it needed to raise prices on several products. Memory now sets part of what you pay, and Micron's own forecast says demand is still climbing.
Who's Accountable

So when does it ease? Not next quarter, if Micron's own forecast holds. That forecast beats the $57 billion analysts had expected. Its chairman and chief executive, Sanjay Mehrotra, said the company expects "an even stronger fiscal 2027."
New supply is the thing to watch. Micron is investing $250 billion to build two campuses that make high-bandwidth memory, and its first new factory in Boise, Idaho, is scheduled to come online next year. Its rivals in South Korea are building new factories too.
Until then, buyers are paying ahead. Micron's cash flow statement shows $12.7 billion in customer deposits in its latest year, up from none the year before. That is a shortage seen from the seller's side.
