Key Points
Micron's explosive growth was fueled by surging demand for its high-bandwidth memory chips used in AI servers.
The company's market capitalization is now more than $1.1 trillion.
Micron Technology (NASDAQ: MU) stock went on an absolute tear this year as the market reacted to insatiable demand for the memory chips it makes. Its run has been nothing short of remarkable, rivaling that of AI behemoth Nvidia just a few years ago.
Five years ago, could anyone have anticipated Micron's monster rally? Not likely. That's why you could snag shares at less than $80 while they're now trading close to $1,000.

Take a look at the incredible growth in the chart below.
Micron rode the AI wave to a $1 trillion valuation
The chart is so zoomed out that it's hard to tell, but the ride up was not smooth. Micron fell hard in 2022 as memory prices crashed, then clawed back in 2023. It finally exploded this year once AI servers created insatiable demand for its high-bandwidth memory (HBM) chips. The company crossed a $1 trillion market cap in May 2026.
While it looks like demand will continue for some time, I think the boom-bust nature of memory chip stocks will continue, and now is not the time to jump in. If demand cools even a little, the stock could fall hard once again.
