Facebook's parent company Meta has struck a $6 billion agreement with fiber manufacturer Corning Incorporated to speed up the buildout of data centers in the US.

As part of the multi-year agreement, Corning will supply Meta with its latest fiber, cable, and connectivity products.

It follows Meta's announcement in November that the hyperscaler would invest $600 billion in digital infrastructure in the US over the next three years.

Corning confirmed it will expand manufacturing capabilities across its operations in North Carolina, which the company notes includes a "significant capacity expansion" at its optical cable manufacturing facility in Hickory, where Meta will serve as the anchor customer.

The company also said the agreement with Meta will create new jobs in the state.

“This long-term partnership with Meta reflects Corning’s commitment to develop, innovate, and manufacture the critical technologies that power next-generation data centers here in the US,” said Wendell P. Weeks, chairman and chief executive officer, Corning Incorporated.

Weeks said the expansion will increase its employment in North Carolina by 15 to 20 percent, and "help sustain a highly skilled workforce of more than 5,000 — including the scientists, engineers, and production teams at two of the world’s largest optical fiber and cable manufacturing facilities."

"Together with Meta, we’re strengthening domestic supply chains and helping ensure that advanced data centers are built using US innovation and advanced manufacturing," he added.

Meta currently has 30 data center campuses in operation or development globally, with 26 located in the US, according to Meta's website.

“Building the most advanced data centers in the US requires world-class partners and American manufacturing,” said Joel Kaplan, chief global affairs officer at Meta. “This collaboration will help create good-paying, skilled US jobs, strengthen local economies, and help secure the US lead in the global AI race.”

Meta has already announced a significant data center spend. In October, the company warned investors that capex costs will be "notably larger" in 2026 than in 2025. Alongside its own gigawatt data center construction projects, Meta reportedly signed a $10bn+ cloud deal with Google in August, followed by a $14.2bn CoreWeave deal last September, a $3bn Nebius contract in November, and is in talks with Oracle for a $20bn contract.

To fund its 2GW Hyperion data center, the company entered into a $27bn joint venture with Blue Owl Capital, with the latter company covering 80 percent of the cost.
