T-Mobile has announced two fiber joint ventures valued at approximately $2.7 billion, accelerating its broadband expansion strategy and extending high-speed connectivity to more than 1 million additional homes across the United States.
The company will form a 50:50 joint venture with Oak Hill Capital to acquire and integrate GoNetspeed and Greenlight Networks. This combined platform is expected to pass over 1.3 million households by the end of 2026, with coverage spanning key Northeastern and mid-Atlantic markets including Connecticut, New York, Pennsylvania, and Massachusetts.
In a separate deal, T-Mobile will partner 50:50 with Wren House to acquire i3 Broadband. The i3 platform is projected to pass approximately 500 thousand households by the end of 2026, with operations in Missouri, Illinois, and Rhode Island.
T-Mobile expects to invest around $2.0 billion in the Oak Hill joint venture, which is scheduled to close in the first half of 2027, and approximately $700 million in the Wren House partnership, expected to close in the second half of 2026, subject to regulatory approvals.
The move strengthens T-Mobile’s dual broadband strategy, combining its leadership in 5G fixed wireless access with a rapidly scaling fiber footprint. The company has already built a base of about 1 million fiber customers within two years through partnerships and capital-efficient models.
Fiber expansion complements T-Mobile’s 5G growth by enabling multi-gigabit speeds and additional network capacity in targeted markets. These joint ventures also leverage T-Mobile’s national retail presence, brand strength, and customer experience capabilities alongside the infrastructure expertise of its partners.
The company aims to serve 18 to 19 million total broadband customers by 2030, including 3 to 4 million fiber subscribers. The new partnerships are expected to accelerate fiber-to-the-premises deployment while supporting scalable wholesale models and extending high-speed internet access to underserved communities.
