Micron Tops $1,000, Reaches $1 Trillion as AI Memory Demand Sells Out 2026 HBM Supply
3 articles · Updated · The Motley Fool · Jun 21
Summary
$1,000-plus Micron shares pushed the memory-chip maker into the trillion-dollar club as investors bet AI data-center spending will keep lifting HBM and DRAM demand.
Micron says its entire 2026 HBM capacity is already sold out, with DRAM shortages potentially lasting beyond 2027 as hyperscalers keep expanding AI infrastructure.
TrendForce projects the global memory market will hit $1.3 trillion in 2027, with DRAM revenue jumping 303% this year to $619 billion and reaching $903 billion in 2027.
A trailing P/E of 48 looks rich against Micron's historical 3.5-to-8 cycle lows, but multiyear supply contracts and a forward P/E of 9.5 suggest investors expect a more durable AI-driven earnings cycle.
The main risk is familiar: faster capacity additions by Micron and rivals, or slower hyperscaler capex, could revive oversupply and squeeze margins back toward past norms.

Overview
Micron Technology has rapidly risen to become a leading force in the semiconductor industry, marked by a significant surge in its market valuation in late May 2026. Just weeks before May 26, 2026, Micron surpassed a $700 billion market cap, reflecting strong investor confidence in its future. This momentum was fueled by robust stock performance and a substantial jump in share price, further boosted by positive attention from U.S. political leaders. President Donald Trump publicly praised Micron for its massive investments in the U.S. economy, highlighting the company’s strategic importance and reinforcing its impressive ascent.
