Corning (GLW) has climbed 137.4% year to date, making it one of the market's standout performers in 2026.1 The driver: an expanded long-term partnership with NVIDIA, positioning Corning as a key supplier for AI data center infrastructure.
NVIDIA and Corning have deepened their supply agreement as hyperscalers race to build out AI compute capacity. Corning is set to construct three new manufacturing facilities to meet projected demand.1 The expansion targets fiber optic cables and specialty glass components used in high-speed data center interconnects.
AI infrastructure buildout is creating structural demand for optical communications hardware. Data centers handling large language model training and inference require dense, low-latency fiber networks. Corning's optical communications segment is positioned directly in that supply chain.
Enterprise adoption is accelerating on the demand side. 98% of businesses were investigating generative AI in 2025, with 39% running active production deployments.2 That shift from pilot to production translates into sustained capital expenditure on physical infrastructure — servers, networking, and the fiber connecting them.
Google Cloud's 2025 State of AI Infrastructure Report confirms the pattern: investment in AI compute is pulling forward spending across the full stack, including interconnects and optical transport.2 Corning sits at that intersection.
The NVIDIA partnership matters strategically beyond revenue. NVIDIA's data center GPU roadmap dictates the pace of cluster deployments globally. A long-term supply agreement with NVIDIA effectively locks Corning into multi-year infrastructure cycles and provides revenue visibility that the market is pricing in.
Corning's optical communications segment had previously been under pressure from slower telecom spending. The pivot to data center demand changes the growth profile. Three new facilities represent a significant capacity bet — one tied to the timeline of AI infrastructure deployment rather than traditional telecom upgrade cycles.
Investors are treating Corning as a picks-and-shovels play on AI infrastructure. The 137.4% YTD gain reflects that re-rating. Whether the stock can hold those gains depends on whether AI capital expenditure maintains its current trajectory and whether Corning executes on the facility buildout timeline.1
