Micron’s Rally Pushes It Past $1 Trillion as AI Memory Shortage Drives a Narrow Market Surge

The run-up reflects sold‑out high‑bandwidth memory and fast DRAM ramping that could prove a structural shift for AI infrastructure or spark sharp reversals when Micron reports on June 24.

Overview

  • Micron briefly crossed the $1 trillion market‑value mark on May 26 after reports that its 2026 high‑bandwidth memory (HBM) capacity is fully sold out and investors priced in steep AI server demand.
  • The company said it began 1‑alpha DRAM production at its Manassas, Virginia, fab on May 22 and has started work on next‑generation HBM4 devices, tightening supply for GPUs and custom AI accelerators.
  • Wall Street has sharply raised forecasts and price targets, with consensus estimates pointing to about $33.7 billion in revenue and $19.21 in EPS for Micron’s fiscal third quarter and at least one analyst boosting a price target to $1,625.
  • The equities rally has been highly concentrated in a handful of semiconductor names, helping U.S. indexes hit record highs while only roughly 60% of S&P 500 stocks trade above their 200‑day averages, which raises market fragility.
  • Key risks include the memory market’s history of boom‑and‑bust cycles, potential competitor capacity allocations, and geopolitical export limits, any of which could quickly reverse valuations and amplify volatility after the June 24 earnings report.
