Memory chip stocks are on fire again: MU, SNDK, WDC, and STX soar as Micron earnings stun Wall Street

But the reason for this specific surge comes down to just one of the four companies: Micron Technology Inc. (Nasdaq: MU). Yesterday, Micron reported its Q3 2026 results after the closing bell, and those results were nothing short of breathtaking. Here’s what you need to know. What’s happened? Yesterday, Micron Technology reported its third-quarter results for its fiscal 2026. They came in well above even the most ambitious estimates. For its Q3 2026, Micron generated revenue of $41.46 billion. To put that number into greater context, the company generated revenue of just $23.86 billion for the prior quarter. That means in just a single quarter, Micron’s revenue grew by nearly $18 billion. But even more astounding is Micron’s year-over-year growth. When comparing the company’s 2026 Q3 versus its 2025 Q3, Micron’s revenue more than quadrupled. Quadrupled. In Q3 2025, Micron’s revenue came in at $9.3 billion. Its Q3 2026 revenue was nearly four and a half times that. And to put Micron’s results into even further context, the company’s Q3 numbers solidly outperformed even Wall Street’s ambitious estimates. As noted by CNBC, LSEG consensus estimates put Micron at just under $36 billion for the quarter. Mircon blew past those estimates to the tune of around $5.5 billion. Why is demand for Micron’s chips so strong? Mircon can, of course, thank the AI era for its revenue windfall. While powerful GPUs like those made by Nvidia were once the golden component of hyperscaler data center buildouts, the bottleneck has now shifted to memory and storage chips. Demand for both components has been off the charts, and with the largest hyperscalers like Meta, Google, and Amazon throwing tens of billions around to acquire them, it has led to massive shortages elsewhere, particularly in consumer electronics like laptops and smartphones. This memory chip shortage has enabled Micron and other ch
