The Company That Makes Glass for iPhones Sees Its Stock Price Soar 500% Because of AI
The iPhone screen glass supplier Corning, known for Gorilla Glass, is experiencing a meteoric rise driven by the AI boom, with its stock price increasing fivefold over two years. The catalyst is a dramatic shift in its core business. While historically reliant on telecom and display glass, its optical communications division—inventor of low-loss fiber optics—has become the growth engine, fueled by massive AI data center demand.
AI training requires vastly denser "east-west" data traffic between thousands of GPUs, making traditional copper cables inadequate and creating an urgent need for high-bandwidth, low-latency fiber optics. Corning has secured at least four multi-year contracts worth tens of billions of dollars in recent months, including deals with Meta and two unnamed companies. Its optical communications revenue surged 35% in 2025.
A key factor is Corning's "Springboard" plan, which boosted profits faster than sales through premium pricing, product upgrades for AI clusters, and utilizing idle capacity. Its innovations, like rollable ribbon fiber that triples capacity within existing conduits and cuts installation time, command a significant premium as they save critical months in AI factory construction.
NVIDIA's recent $5 billion investment in Corning (with an option to increase to $32 billion), including nearly free shares, signals a strategic partnership. This is part of NVIDIA's broader move beyond chips to becoming an "AI factory" systems integrator, securing a trusted, high-capacity fiber optics supplier for its blueprint. Corning, once seen as a mature manufacturer, is now central to building the AI infrastructure's nervous system.
