AT&T signs multiyear $3 billion-plus deal with Corning to expand fiber network

AT&T announced a multiyear partnership with Corning valued at more than $3 billion to supply fiber and cable for its broadband expansion. The agreement aims to grow AT&T’s fiber footprint to 60 million customer locations by the end of 2030. The carrier added 646,000 internet customers in Q2 2026, including 367,000 new fiber subscribers. AT&T expects average household data use on its fiber service to rise from over 1 TB per month now to 2‑2.5 TB by 2030.

The long‑term supply arrangement gives AT&T a steady source of fiber components, supporting its goal to reach 60 million locations and sustain customer growth, which could improve revenue from broadband services (the company says). Corning, listed under GLW, stands to benefit from increased demand for its fiber products.
