Micron’s Trillion-Dollar Rally Faces an Earnings Test

Investors are betting on a beat‑and‑raise after Micron said 2026 high‑bandwidth memory is sold out and announced a supply deal with Anthropic, leaving 2027–28 capacity guidance as the key risk to its valuation.

Overview

  • Micron’s shares have climbed past $1,000 and pushed the company into the trillion‑dollar market‑cap range on broad analyst upgrades and strong demand for high‑bandwidth memory, the stacked DRAM used beside AI accelerators.
  • The company says its 2026 HBM production is effectively sold out and has struck a multi‑year supply and investment partnership with AI firm Anthropic that covers HBM, DRAM, and SSDs.
  • Wall Street has responded with dozens of buy and strong‑buy ratings and large 12‑month price‑target increases, with many targets clustered in the $1,300–$1,500 range and some higher.
  • The immediate catalyst is Micron’s fiscal third‑quarter report, which investors expect to beat and raise guidance when results arrive on Wednesday, June 24, and which markets view as decisive for near‑term price moves.
  • Analysts warn the memory market is historically cyclical and that aggressive capacity expansion—notably by Chinese manufacturers—could ease tightness and pressure prices around 2027–2028, which would test whether today’s valuations are sustainable.
