AI Infrastructure Demand Drives Tech Rally Led by Western Digital and Corning

Key Facts

Amid the accelerating expansion of AI infrastructure, technology and semiconductor stocks rallied as data center demand and analyst upgrades fueled investor optimism. Western Digital stock climbed 7.00% following a price target hike by Susquehanna, while Corning rose 7.07% driven by major fiber optics supply agreements with Amazon and Meta. Additionally, Meta Platforms gained 4.76% as the company moves forward with plans to manufacture proprietary AI semiconductors starting this September.

This momentum reflects a strategic shift toward hardware providers essential for cloud computing, as Big Tech firms race to secure critical supply chains. In comparison to sector peers, MSFT closed at $384.36 and GOOGL at $358.89 per market data on July 9, 2026, suggesting a rotation of capital into specialized infrastructure plays. Recent industry reports highlight that storage and optical communication components are becoming central to supporting generative AI workloads.

Traders are now monitoring key technical levels, with WDC closing at $550.3 (as of July 8, 2026) and META at $631.48 (as of July 9, 2026). With the economic calendar showing few immediate catalysts for the semiconductor sector, market attention remains fixed on Meta's manufacturing milestones in September. Meanwhile, NVDA closed at $202.78 and AMZN at $247.04 on July 9, 2026, as investors await further guidance on corporate capital expenditure trends.
