Verizon and Corning announced a multi-year, multi-billion-dollar supply agreement on Tuesday that will see the glassmaker deliver more than 80 million miles of optical fiber to the telecom carrier between 2027 and 2032, extending a partnership between the two companies that stretches back three decades.

The deal, detailed in a joint announcement, covers Corning's Contour Flow Cable technology, which packs more optical fiber into existing conduit pathways — letting Verizon expand its network without tearing up as much ground.

Broadband and AI, Bundled Together

The fiber is earmarked for two fronts at once. Most of it will support Verizon's consumer broadband push, as the carrier works toward a goal of reaching 40 to 50 million fiber-to-the-home and business passings. The rest will serve as backbone infrastructure connecting data centers along major long-haul corridors — capacity increasingly in demand as AI workloads strain existing networks, according to 24/7 Wall St.

Investors cheered the news. Corning shares climbed roughly 3% following the announcement, as markets weighed the long-term revenue visibility the agreement locks in for the glass and materials company through the end of the decade.

A THREE-DECADE PARTNERSHIP, EXTENDED THROUGH 2032

The agreement arrives as telecom carriers nationwide race to future-proof their networks against two converging pressures: consumer demand for faster home internet and the explosive growth of AI data centers, which require enormous fiber capacity to move data between facilities. Verizon has increasingly framed its infrastructure spending around both use cases simultaneously, rather than treating broadband and AI buildouts as separate businesses.

Neither company disclosed the exact dollar value of the agreement. Corning has previously flagged its optical business as one of its fastest-growing segments, driven in large part by demand tied to AI infrastructure buildouts from hyperscale cloud providers.
