Micron reports earnings soon and the Street is treating the print as a bellwether for AI memory demand, particularly HBM (high-bandwidth memory) used in GPU clusters. FY2025 revenue run-rate of $37.4B reflects 48.9% YoY growth, with gross margins expanding to 39.8% and diluted EPS of $7.59 — a dramatic recovery from prior-cycle lows that sets a tough comparable going forward.

The setup is classic high-bar binary: if Micron guides strongly on HBM shipments and data-center DRAM pricing, it validates the AI infrastructure spending narrative and likely lifts NVDA, AMD, and the broader SOX. If guidance disappoints — on pricing pressure, China export restrictions, or PC/smartphone DRAM weakness offsetting AI gains — the market risks reading it as a cycle peak signal. Watch HBM revenue mix and next-quarter ASP commentary most closely.
