Why Micron Stock Skyrocketed Last Month But Is Plummeting in July - Yahoo Finance

Micron Technology surged 18.9% in June 2026, driven by a strong quarterly earnings report and positive sentiment around the artificial intelligence (AI) memory chip market. The company reported $41.46... Read original →

Micron’s June euphoria masked structural fragility in the AI memory market. While HBM3E/HBM4 ramp-up benefited from NVIDIA’s Blackwell deployment, Meta’s shift toward in-house AI inference chips and third-party services erodes DRAM vendors’ pricing power in training workloads. Technologically, tighter integration between high-bandwidth memory and advanced packaging forces Micron to accelerate CoWoS-compatible investments, inflating capex. Geopolitically, tightening U.S. export controls and constrained mature-node expansions in Taiwan, China, have embedded supply-chain redundancy costs into gross margins. Samsung and SK Hynix are exploiting this by locking in long-term server deals. Over the next 18 months, the sector will pivot from “AI memory shortage” to “structural oversupply”—only players with superior HBM yields and heterogeneous integration capabilities will survive the shakeout.
