Seagate's stock dropped more than 9% Monday after CEO Dave Mosley signaled the storage company may struggle to meet surging demand from AI infrastructure buildouts. The decline triggered a broader sell-off across the memory chip sector.

The storage manufacturer's shares led a group-wide decline after Mosley's comments raised red flags about supply constraints during a period of explosive AI-driven demand for data center capacity. Memory and storage companies have positioned themselves as key beneficiaries of the AI boom, as data centers require substantial infrastructure upgrades to support large language models and other AI systems. However, Seagate's inability to confidently commit to meeting this demand suggests potential bottlenecks in manufacturing or supply chain challenges. The sell-off extended beyond Seagate, with other memory chip makers also experiencing declines. Investors had previously viewed the AI buildout as a significant tailwind for the sector, making concerns about supply constraints particularly damaging to market sentiment. The move underscores investor sensitivity to execution risks within companies positioned to capitalize on AI growth. While demand projections remain robust, manufacturers' ability to scale production has become a critical factor for valuations.
