On July 2, Corning fell 3.68% in pre-market trading, trading at approximately $213.92/share. The decline was primarily triggered by reports that Meta plans to sell surplus AI computing power resources to external clients, which the market interpreted as a signal that AI capital expenditure growth may be decelerating.

The news prompted a broad sell-off across the AI hardware supply chain, with storage and optical communications stocks falling in tandem. Micron Technology dropped 3% and SanDisk declined 2.5%, while Corning, as a leading optical communications supplier, bore significant pressure. Additionally, Corning had accumulated substantial short-term gains following its GlassBridge glass-based optical interconnect technology launch and FTSE Russell index inclusion, which drove a single-day surge exceeding 15% on June 29. The combination of half-year institutional portfolio rebalancing and concentrated profit-taking from earlier gains intensified the pullback.
