T-Mobile announced Tuesday it has entered into agreements for two major joint ventures worth a combined $2.7 billion, marking a significant expansion of the wireless carrier’s fiber internet operations to support its growing broadband customer base.
The first partnership involves Oak Hill Capital, where T-Mobile will acquire a 50% ownership stake in a venture that merges two fiber companies already owned by the private equity firm – GoNetspeed and Greenlight. T-Mobile plans to invest approximately $2 billion in this joint venture, which is expected to finalize during the first six months of 2027.
The second collaboration pairs T-Mobile with Wren House, a global infrastructure investment firm, and includes the purchase of i3 Broadband, a regional fiber provider that delivers internet services across portions of Illinois, Missouri and Rhode Island. This venture will require an investment of roughly $700 million for T-Mobile’s 50% share, with completion anticipated in the latter half of 2026.
These strategic partnerships will expand T-Mobile’s fiber network reach to more than one million additional households across the United States. The expansion supports the company’s ambitious goal of serving between 18 million and 19 million broadband subscribers by 2030, with fiber customers accounting for 3 million to 4 million of that total.
The moves represent T-Mobile’s continued effort to diversify beyond traditional wireless services and compete more directly in the home internet market alongside its rapidly expanding broadband offerings.
