Micron Stock Climbs as HBM Sells Out: June 24 Earnings Decides the AI Memory Trade - Tech Times

Micron Technology has surged around 70% in 2026, emerging as one of the defining AI-driven trades in the semiconductor sector. The primary catalyst is the severe shortage of high-bandwidth memory (HBM... Read original →

Micron’s sell-out of 2026 HBM capacity reflects the acute 'memory wall' crisis in AI compute scaling. Technically, imminent HBM4 ramp-up will strain CoWoS packaging supply and inflate BOM costs for GPUs, forcing system architects to rethink efficiency trade-offs. Geopolitically, tightening U.S. export controls raise compliance overheads as Micron diversifies production beyond Taiwan, China and South Korea. With SK Hynix locking NVIDIA via HBM3E and Samsung accelerating HBM4 yields, Micron must reinvest its 70%+ gross margins into R&D or risk obsolescence. Over the next 18 months, HBM could transition from cyclical commodity to structurally scarce asset—if AI capex holds. But saturation in large-model training or breakthroughs in near-memory computing would swiftly invalidate today’s valuation premium.
