How a $1,000 Micron investment in 1984 became $400,000 today
A $1,000 investment in Micron Technology at its 1984 launch would now be worth over $400,000. The Idaho-based memory chip maker has grown steadily alongside the tech industry's expansion. Its journey reflects both booms and busts over four decades.
Micron went public in 1984 with a market value of around $135 million. Back then, buying shares required a phone call to a broker. By the mid-1990s, the stock had surged more than fivefold, driven by demand for DRAM chips in personal computers.
The dot-com era pushed Micron's value even higher. By March 2000, that original $1,000 would have grown to over $50,000. But the subsequent crash wiped out much of those gains, leaving the stock stagnant for years.
Recovery came slowly. It took nearly two decades for Micron to reclaim its dot-com peak. By January 2026, its market cap reached about $120 billion, far below rivals like Nvidia, which hit $3 trillion, or Samsung, exceeding $400 billion. Still, Micron's stock trades at roughly 12 times forward earnings—a discount compared to the stock market's average of 25.
Today, every dollar invested in Micron in 1984 is worth about $414. The company's growth mirrors the broader rise of memory technology in computing. With demand for DRAM and NAND still strong, analysts see room for further gains.
