Micron Soars 11.7% in Single Day, Storage Chip Sector Boosted by "AI Boom Cycle" Logic

June 12 – Micron Technology posted a strong 11.7% gain in Thursday’s closing trading, triggering stabilization and a rebound across the global memory chip sector and reigniting market optimism about the storage cycle’s long-term sustainability. A Morgan Stanley analyst labeled the recent pullback a phased retreat within an upward cycle—not a full trend reversal. He emphasized that ongoing buildout of artificial intelligence (AI) infrastructure is driving surging DRAM demand, with storage standing as a critical bottleneck for expanding AI computing power. Research shows DRAM prices have now entered a steep upward trajectory, and some long-term supply agreements are starting to lock in production capacity. This shift is moving the industry away from a spot-driven model toward one dominated by contracts, a change that could reshape how the storage sector is valued. Wolf Research similarly noted that AI data center demand is vastly outpacing supply growth, meaning DRAM and NAND prices will likely stay elevated or even rise further over the next several years. With supply expansion constrained, the current price hike cycle could extend through 2027—or longer. Still, analysts cautioned that historically, storage cycles have typically ended in oversupply fueled by broad-based production expansion. Whether today’s high market prosperity holds through 2028 will depend on two key factors: the industry’s ability to maintain capacity discipline, and the extent to which projected AI demand actually materializes.
