Micron Is Up 700% in a Year. A Stock Split Hasn't Been This Likely Since 2000.

    Micron Technology (NASDAQ: MU) hasn't split its stock in over 25 years. The last time was May 2, 2000. Back then, shares traded under $90 and the dot-com bubble was still inflating.

    Today, MU is up nearly 700% over the past 12 months. The share price has climbed well into triple-digit territory, and the split conversation is getting louder by the week.

    Why the Price Matters

    A stock split doesn't change the value of your holdings. If Micron did a 10-for-1 split, each share would be divided into 10 new shares at one-tenth the price. Your total position stays the same.

    But there are practical reasons companies do this. A high per-share price puts a stock out of reach for many retail investors buying whole shares. Fractional share trading helps, but a lower price still increases liquidity and broadens the investor base. Nvidia, Amazon, and Alphabet all split for the same reasons in recent years.

    Micron has done this three times before. Each time, the stock was trading at a level that was becoming unwieldy for retail investors. We're well past that threshold now.

    The Business Behind the Price

    This isn't a meme stock run. Micron's numbers back up the move.

    In the second quarter of fiscal 2026, Micron reported $23.9 billion in revenue. That's a 196% increase from the same quarter a year ago, and it marked the company's fourth consecutive quarterly revenue record.

    The driver is artificial intelligence. Specifically, high-bandwidth memory (HBM) chips that power AI data centers. These are the memory modules that sit next to the GPUs doing the heavy computing. Without them, the processors can't move data fast enough to run large AI models.

    Micron confirmed that its entire HBM4 supply for 2026 is sold out under binding contracts. Customers are now signing three- to five-year supply agreements. That's a level of demand visibility that memory companies almost never get. This industry has historically been brutally cyclical, with boom-and-bust swings that punish investors who buy at the top. The current setup is different because the contracts lock in revenue years in advance.

    What Would Trigger the Split

    Micron's board hasn't announced anything. There's no filing, no timeline, and no public signal from management that a split is imminent.

    But the conditions are all in place. The stock has run nearly 700% in 12 months, and some analysts project further upside through the end of 2026. If the price keeps climbing, the per-share cost becomes an even bigger barrier for retail buyers.

    Companies typically split after a long price run, not during one. So the most likely timing, if it happens at all, would be sometime after Micron's next earnings report when the board can point to continued execution.

    What It Means for Investors

    A stock split is cosmetic. It doesn't change Micron's revenue, margins, or competitive position. The only thing that changes is the number of shares outstanding and the price per share.

    That said, splits do tend to generate short-term interest. Research has shown that stocks often see increased trading volume and modest price bumps in the weeks around a split announcement. Whether that effect lasts is a different question.

    The real story here is simpler. Micron's memory business is in the strongest stretch it has ever had. Revenue nearly tripled year over year. Supply is locked up for years. And the AI infrastructure buildout that's driving demand shows no sign of slowing.

    Whether or not the stock splits, the underlying business is what matters.
