Corning Signs Multi-Year Nvidia Partnership — 1,000% Optical Connectivity Capacity Expansion, Three New Plants

Corning (GLW) has announced a multi-year partnership with Nvidia to expand its U.S. fiber production capacity by more than 50% and its optical connectivity manufacturing capacity by 1,000%. Three new advanced manufacturing facilities will be built in North Carolina and Texas, as Corning shares have surged 137% year-to-date.

The AI revolution's windfalls haven't been limited to chipmakers like Nvidia or Broadcom. Corning, a 175-year-old U.S. manufacturer, has emerged as one of the year's hottest industrial stocks thanks to its position as the backbone of AI data center connectivity. Now, it has secured a massive multi-year partnership with Nvidia.

From Fiber-Optic Backwater to AI Infrastructure Backbone

Corning is best known for specialty glass products: the Gorilla Glass on your smartphone, display glass for LCD TVs. But for over a decade, its largest revenue driver has been fiber-optic cable. The problem was that from 2015 to 2023, that business delivered low growth and thin margins, and the stock gained just 32.8% over those nine years.

The turning point was AI. Modern AI workloads require connecting thousands of GPUs to move massive amounts of data at extraordinary speeds — exactly what fiber-optic cables do best. Corning had been optimizing its cables for data center applications since 2018. When demand exploded, Corning was ready. The issue was supply.

The Nvidia Partnership: Three New Plants, 1,000% Capacity Expansion

Nvidia has officially announced a multi-year partnership with Corning aimed at "dramatically expanding U.S.-based manufacturing of the advanced optical connectivity solutions needed to power next-generation AI infrastructure."

• U.S. fiber-optic production capacity: +50% or more
• U.S. optical connectivity manufacturing capacity: +1,000%
• Three new advanced manufacturing facilities to be built in North Carolina and Texas
• Output will supply optical connectivity to hyperscale data centers powered by Nvidia GPUs

"Modern AI workloads require thousands of GPUs — requiring unprecedented volumes of high-performance optical fiber, connectivity, and photonics to move data at extraordinary speed and scale. As AI factories grow larger and more numerous, optical connectivity becomes an important component of the AI infrastructure."

Running at Maximum Capacity — Supply Is the Problem

Corning is already producing fiber-optic cable at maximum capacity and selling it all as fast as it's made, at an approximately 21% profit margin — well above the 10–15% margins the company earned for years. With hyperscaler demand still accelerating and Corning as both the world's largest fiber manufacturer and the dominant North American supplier, Nvidia had every reason to lock in this partnership.

Stock Up 137% YTD — Valuation Has Caught Up

Corning shares have surged 137% year-to-date, trading around $192 with a market cap of approximately $165 billion. The stock is up more than fourfold from its 52-week low of $47.40. The dividend yield stands at 0.58%.

The valuation now reflects those expectations. Corning trades at roughly 100x trailing earnings and 65x forward earnings — actually more expensive than Nvidia on a forward basis. For investors putting new money to work in AI infrastructure stocks, Nvidia may offer a more attractive entry point, while existing Corning shareholders can take comfort that the Nvidia partnership removes near-term concerns about manufacturing constraints.
