Corning (GLW) stock rose as investors bid up shares of the specialty glassmaker amid continued momentum in artificial intelligence infrastructure spending, with the company positioned as a critical supplier of fiber optic cables that connect AI data centers.
Corning has emerged as a key beneficiary of the global race to build AI infrastructure. The company supplies advanced optical fiber, cable, and connectivity products designed for the high-density demands of AI data centers. Amazon, which is investing up to $200 billion on AI infrastructure in 2026, relies on companies like Corning to build the connectivity backbone of its cloud and data center operations.
The company has announced multiple major partnerships this year. In January 2026, Corning struck a deal with Meta worth up to $6 billion through 2030 to supply fiber-optic cable for AI data centers. In May 2026, Nvidia announced a long-term partnership with Corning, committing up to $500 million to expand Corning’s U.S. fiber optic manufacturing capacity in North Carolina and Texas. These deals underscore how AI infrastructure buildouts are creating sustained demand for Corning’s materials.
Corning’s stock has surged more than 50% year-to-date in 2026, driven by the convergence of strong earnings, multiple large customer commitments, and analyst upgrades reflecting confidence in the company’s position in the AI boom. The fiber optics segment is seeing particular strength as data center operators prioritize glass-based connectivity over copper alternatives, which are less energy efficient.
