On July 27, Western Digital rose 3.05% overnight, trading at $537.11/share, with turnover of $2.0589 million, as the broader storage sector staged a collective rebound driven by persistent AI infrastructure demand expectations.

On the news front, strong demand expectations for AI infrastructure continued to support sector sentiment. SK Hynix Chairman stated that AI semiconductor demand is expected to grow 60% to 100% year-over-year next year, with supply-demand gaps set to widen further as major manufacturers have virtually no substantial capacity expansion plans. Morgan Stanley noted that Q3 data center memory prices rose at least 25% quarter-over-quarter, highlighting memory as a primary bottleneck in AI infrastructure — a structural constraint expected to persist for years.

Additionally, Western Digital recently unveiled a 100TB HDD roadmap at the World Artificial Intelligence Conference, advancing both HAMR and ePMR technologies in parallel with a target of achieving 100TB per drive by 2029, elevating market attention toward its long-term AI storage positioning. Sector peers also traded higher, with SanDisk up 3.25%, Seagate Technology up 2.53%, and Super Micro Computer up 2.39%.
