Meta and Nvidia are locking up fiber optic supply for years — and everyone else is waiting
AI data centers need more than chips — they need fiber, and right now there isn't enough to go around. North American demand for optical fiber is projected to grow 22–25% in 2026, while supply can only expand 12–19%, per Rebio Group. That gap is already showing up as 20-week lead times for large buyers and waits approaching a full year for smaller operators. For anyone building network infrastructure right now, this is a real bottleneck.
The lockup
Meta moved first. In January 2026, the company signed a multiyear deal worth up to $6 billion with Corning — the dominant US optical fiber maker, controlling roughly 10.4% of the global market — to secure supply for its planned network of 26 US data centers, reports CNBC. The deal anchors a manufacturing expansion at Corning's North Carolina facilities. Nvidia followed in May 2026 with a partnership that could reach $3.2 billion, including a $500 million upfront securities purchase and warrants for additional equity, to fund three new optical manufacturing plants in North Carolina and Texas, reports CNBC. Together, these deals hand two companies preferential access to a supplier that has already stopped selling raw glass to third parties.
Optical fiber demand is outpacing production capacity, with lead times stretching well beyond a year for smaller buyers.
Who gets squeezed
The ripple effects go beyond corporate rivalry. The US government's $42.45 billion BEAD broadband program — meant to bring fiber internet to underserved communities — is now competing for the same cables as hyperscale AI builds. A federal "Build America, Buy America" rule limits eligible suppliers to just three US manufacturers: Corning, OFS, and Prysmian. With Corning's capacity increasingly committed to Meta and Nvidia, BEAD contractors in 18 approved states face the same supply crunch during the program's peak construction window of 2026–2027. Ribbon fiber — the type used in high-density data center deployments — now carries lead times exceeding 60 weeks, according to Fierce Network.
The price signal
Prices are moving sharply upward. Global fiber cable costs have risen roughly 70% since 2021. In China, prices for specialized optical fiber surged around 80% between November 2025 and January 2026 alone. Corning's own enterprise optical sales jumped 58% year-over-year in Q3 2025, driven entirely by AI infrastructure demand — and CEO Wendell Weeks has acknowledged supply is "very tight." The market is becoming a closed club: companies with the capital to lock in multiyear contracts get product; everyone else joins the queue.
