NVIDIA invests $500 million in Corning optical connectivity deal as AI data center bandwidth becomes critical bottleneck

NVIDIA will purchase 3 million Corning shares at $0.0001 each and receive warrants to buy up to 15 million additional shares at $180 apiece. Corning will build three new U.S. factories in North Carolina and Texas, expanding optical connectivity manufacturing capacity by tenfold and fiber production capacity by 50%, expected to add over 3,000 American jobs.

Optical connectivity (fiber and silicon photonics technology for data transmission) is becoming the limiting factor in AI data centers. As GPU clusters scale to hundreds of thousands of accelerators, copper cannot efficiently handle the bandwidth required over longer distances, making the optical layer critical to prevent data-movement bottlenecks.

Corning's Optical Communications revenue reached $1.85 billion in Q1 2026, up 36% year over year. The company has also signed multiyear deals worth up to $6 billion with Meta Platforms and two additional hyperscale customers, signaling sustained demand for optical infrastructure.
