Corning's stock has skyrocketed over the past three years, with a combined gain of 400%, making it one of the best performers in the S&P 500. This surge is driven by the company's role as a key supplier of fiber optic cables for the booming AI data center market, as tech giants like Meta, Amazon, Microsoft, and Alphabet ramp up infrastructure spending. Corning's fiber optic cables are replacing copper due to their ability to run cooler and more efficiently power AI systems. The company has also secured major deals with Apple and other device makers for its specialty glass products.

Why it matters

Corning's success highlights the critical importance of infrastructure for the AI revolution. As AI models and applications become more advanced, the need for energy-efficient and high-bandwidth data centers is growing exponentially. Corning's position as a leading supplier of the necessary fiber optic cabling makes it a key beneficiary of this trend, driving its impressive stock performance.

The details

Corning's optical communications segment, which includes its fiber optic cables, accounted for 38% of overall sales last quarter and saw 35% revenue growth and a 71% increase in net income in 2025. The company has secured major deals, including a $2.5 billion agreement with Apple to manufacture all glass for iPhones and Apple Watches at a Kentucky facility. Corning has also partnered with Nvidia to enable AI data centers to link the chipmaker's GPUs using its silicon photonics technology.

  • In March 2025, Corning was announced as one of Nvidia's partners for its silicon photonics ecosystem.
  • In August 2025, Corning announced a $2.5 billion deal with Apple to manufacture all glass for iPhones and Apple Watches at a facility in Harrodsburg, Kentucky.
