Just been thinking about something that could shape the biggest business in the world over the next few years. There's this AI boom happening right now, and while everyone's focused on the companies building the models, there's actually a quieter story unfolding with the memory chip makers who supply the infrastructure.

Micron Technology is basically sitting in the sweet spot here. They're one of the essential suppliers for AI hardware, and the orders coming in for their high-bandwidth memory are absolutely massive. What's interesting is that most of the stock price movement we've seen has been based on future expectations of these orders. The real financial impact? That hasn't fully hit the books yet.

Here's where it gets compelling. Three years ago, Micron was posting a $5.8 billion loss. Fast forward to now, and they're pulling in $11.9 billion in net income over the past year. That's the kind of turnaround that shows what happens when your products are suddenly in critical demand. The margins have expanded dramatically too.

But here's the thing that most people miss: comparing Micron's numbers across different time periods can be misleading because this industry runs in cycles. Sometimes demand spikes, prices go up, and the company invests heavily in capacity. Then inevitably, the market softens and things get brutal. You have to compare peak years to peak years or trough years to trough years, otherwise you're just fooling yourself about the real trajectory.

What might be genuinely different this time is how long Micron can ride this wave. In their latest earnings call, they revealed they've already locked in supply agreements with set pricing and volumes for their entire high-bandwidth memory output through 2026. That's significant. CEO Sanjay Mehrotra is now projecting the addressable memory market could grow from $35 billion in 2025 to $100 billion by 2028. That's almost a tripling. They originally thought it would take until 2030 to hit those numbers.

To put that in perspective, the entire DRAM market was only $35 billion as recently as 2024. So we're potentially looking at the biggest business in the world for memory chips emerging over the next couple years. If Micron can maintain pricing power and really capitalize on these supply-demand dynamics, the financial growth we've already seen might just be the opening act.

The stock's already moved significantly, but if these supply agreements and market projections hold up, there's potentially way more upside to come once the revenue and profit actually flow through. This is the kind of situation where the biggest business in the world narrative could actually play out in real earnings, not just in investor expectations. Worth keeping an eye on how this unfolds over the next couple quarters.
