Deutsche Telekom AG, the German telecom giant, owns the majority of T-Mobile US — about 52.8% as of early 2026. That stake gives it effective control, and CEO Tim Höttges has said publicly the company is actively exploring ways to increase it further, potentially toward a full buyout.
This is a story I’ve been tracking because it connects to the T-Mobile post I run alongside this one: the same Deutsche Telekom-controlled structure sits behind the Mint Mobile brand T-Mobile acquired in 2023.

- SoftBank’s role has shrunk dramatically since the 2020 merger, down to roughly 2.5% of shares by early 2026 as it has steadily exited the position.
- Institutional investors including Vanguard and BlackRock hold most of the remaining publicly traded shares.
- T-Mobile’s 2023 acquisition of Mint Mobile means Deutsche Telekom’s control extends to that budget carrier brand as well.
