Meta and Nvidia race to lock down fiber supply amid AI boom

North American demand for optical fiber is expected to increase by 22–25% in 2026, outpacing supply growth projected at 12–19%, according to Rebio Group. This imbalance is causing lead times to stretch beyond 20 weeks for large purchasers and nearly a year for smaller buyers, creating significant delays for network infrastructure projects.

Meta secured a multiyear agreement in January 2026 with Corning, the dominant U.S. fiber producer holding about 10.4% of the global market, committing up to $6 billion to support its network expansion across 26 data centers in the United States. This contract is tied to an expansion of Corning’s manufacturing facilities in North Carolina. Following this, Nvidia announced a partnership in May 2026 potentially worth $3.2 billion, including a $500 million upfront investment and equity warrants, aimed at funding three new fiber manufacturing plants in North Carolina and Texas. These agreements grant both companies priority access to Corning’s limited supply, which has already ceased selling raw glass to other buyers.

Impact on Broadband and Smaller Buyers

The supply strain extends beyond corporate data center builds. The U.S. government’s $42.45 billion BEAD broadband initiative, designed to deliver fiber internet to underserved areas, now faces competition for fiber cables from these hyperscale AI infrastructure projects. Federal regulations restrict eligible suppliers to three U.S. manufacturers—Corning, OFS, and Prysmian—further tightening availability. BEAD contractors in 18 authorized states are encountering the same supply shortages during the critical construction phase of 2026–2027. Lead times for ribbon fiber, essential for high-density data center use, have surpassed 60 weeks, according to Fierce Network.

Rising Costs and Market Dynamics

The price of fiber optic cables has surged approximately 70% globally since 2021. In China, specialized optical fiber prices jumped around 80% between November 2025 and January 2026. Corning’s enterprise optical sales rose 58% year-over-year in the third quarter of 2025, driven solely by AI infrastructure demand. CEO Wendell Weeks has described the supply situation as "very tight." This environment favors companies capable of securing multiyear contracts, effectively creating a closed market where others must endure prolonged delays.
