Who owns T-Mobile? Ownership structure explained (2026)

T-Mobile is one of the three national wireless carriers in the United States, alongside Verizon and AT&T. Its magenta branding, "Un-carrier" marketing, and aggressive subscriber growth have made it a household name for American consumers. Yet the company that runs T-Mobile in the US is not fully American. It is a majority-owned subsidiary of a German telecom giant.

That parent is Deutsche Telekom, one of Europe's largest telecommunications companies and a business with roots in the former German state phone monopoly. Deutsche Telekom spent more than two decades slowly tightening its grip on the US operation, and in 2023 it crossed the threshold into outright majority ownership. As of 2026 it is reportedly exploring a full combination with its US unit.

Understanding T-Mobile's ownership matters because control sits abroad. Strategic decisions, capital returns, and the company's long-term direction answer to Deutsche Telekom's board in Bonn, not to a dispersed base of US shareholders. This article traces who owns T-Mobile, how Deutsche Telekom built its majority, and what that concentrated control means for investors and customers.

T-Mobile US, Inc. is headquartered in Bellevue, Washington, with a second major campus in Overland Park, Kansas, inherited from its Sprint merger. The business does not trace to a lone founder in a garage. Its lineage runs through VoiceStream Wireless, which Western Wireless spun off in 1999. Deutsche Telekom agreed to buy VoiceStream and rival operator Powertel in 2000 in a deal valued at roughly $50.7 billion, completing the acquisition in 2001 and rebranding the unit T-Mobile USA in 2002.

The company that trades today as T-Mobile US was created in 2013, when T-Mobile USA merged with prepaid carrier MetroPCS. The combined entity began trading publicly under the ticker TMUS. It later transformed again in April 2020 by completing an all-stock merger with Sprint valued at about $26 billion, a deal that reshaped the US wireless market from four national carriers to three.

T-Mobile's core business is straightforward. It sells wireless voice and data plans to consumers and businesses, and it has expanded into 5G home broadband and fiber. Growth has been strong. The company reported 7.8 million postpaid net customer additions in 2025, the best in the industry, and ended the year with 142.4 million total customers. Its market capitalization sat around $200 billion in mid-2026, making it one of the most valuable telecom operators in the world. That scale rests on the same mobile-first consumer behavior that has reshaped advertising and commerce over the past decade.

T-Mobile US is listed on the Nasdaq, so anyone can buy its shares. But it is not a widely held company in the usual sense. It is a "controlled company" under stock-exchange rules, because Deutsche Telekom holds a majority of the voting power. That status exempts T-Mobile from certain governance requirements, such as having a majority-independent board.

In practice this means public shareholders own a minority slice of the economics and carry little influence over strategy. Deutsche Telekom sets the direction. The float trades freely and reflects T-Mobile's operating performance, but control is not in play the way it would be at a company without a dominant owner.

T-Mobile has no founder equity to speak of. It is a corporate creation assembled from acquisitions, VoiceStream, Powertel, MetroPCS, Sprint, and the prepaid brand Mint Mobile, rather than a startup built and held by individual founders. There is no founding family or entrepreneur holding a signature stake. The people who built the modern T-Mobile brand, including former chief executive John Legere, were hired executives compensated largely in salary and stock awards, not founders with large ownership positions.

This is a key difference from many technology companies covered in ownership analyses, where a founder retains a controlling or influential block. At T-Mobile, the controlling block belongs entirely to a corporate parent.

The table below summarizes T-Mobile's approximate ownership as of 2026. Figures for Deutsche Telekom's stake vary slightly by filing date and by whether the count reflects economic shares or voting power.

Deutsche Telekom is the majority owner and the single most important entity in T-Mobile's ownership story. It is a public company itself, listed in Frankfurt, and the German federal government remains a significant indirect shareholder in the parent. Deutsche Telekom holds roughly 53% of T-Mobile's outstanding shares. An SEC filing in early 2023 put the figure at 53.9%, and later company disclosures have hovered in the low-to-mid 50s.

Its control is even stronger than the raw share count suggests. Under a proxy agreement tied to the Sprint merger, Deutsche Telekom can vote SoftBank's residual shares. That arrangement pushed its voting control to around 57% in 2025. Deutsche Telekom reached majority ownership in 2023, a goal its chief executive Tim Höttges said the company had pursued since 2021. Höttges has described T-Mobile as the crown jewel of the group, and the US unit accounts for the majority of Deutsche Telekom's revenue and profit.

SoftBank Group, the Japanese investment conglomerate led by Masayoshi Son, became a major T-Mobile shareholder through the Sprint deal. SoftBank owned Sprint, and when Sprint merged into T-Mobile in 2020, SoftBank received roughly a 24% stake in the combined company. For a time it was the second-largest owner.

That position has shrunk dramatically. Deutsche Telekom bought 21.2 million shares from SoftBank for $2.4 billion in 2022, and SoftBank has continued to sell down. In 2025 it accelerated the exit, offloading billions more in T-Mobile stock to help fund a roughly $40 billion investment in OpenAI, which gave SoftBank an ownership position of about 11%. SoftBank funded that AI push by liquidating several holdings, including its entire stake in chipmaker Nvidia. SoftBank's remaining T-Mobile stake is now around 2.5%, and those shares are covered by Deutsche Telekom's proxy.

The rest of T-Mobile, roughly 44% of shares, trades in public hands. Because Deutsche Telekom controls the company, these holders own the economics without meaningful voting sway. The largest of them are passive index-fund managers rather than strategic investors. Vanguard Group, BlackRock, and State Street typically rank as the biggest institutional holders of the free float. Their positions reflect T-Mobile's weight in major US stock indexes, not any strategic interest in the wireless business.

Real control over T-Mobile flows from Deutsche Telekom. Tim Höttges, Deutsche Telekom's chief executive, serves as chairman of the T-Mobile US board, and the parent designates a majority of the board seats. That gives Deutsche Telekom decisive influence over strategy, executive appointments, and capital allocation.

Day-to-day management sits with T-Mobile's own executive team. Srini Gopalan became chief executive officer on November 1, 2025. He had joined T-Mobile earlier that year as chief operating officer following a multi-year succession process, and he previously ran Deutsche Telekom's German operations. His appointment kept the top job within the wider Deutsche Telekom orbit.

Gopalan succeeded Mike Sievert, who led T-Mobile from April 2020 through October 2025 and oversaw the Sprint integration and a long run of subscriber growth. Sievert did not leave the company. He moved into a newly created role of vice chairman, advising on long-term strategy. What is confirmed is that Deutsche Telekom holds board control and appoints leadership. What is inferred is how influence will divide between Gopalan, Sievert, and the parent as the two companies discuss deeper integration.

The 2020 merger with Sprint faced heavy regulatory opposition. Combining T-Mobile and Sprint reduced the number of national US carriers from four to three, and a coalition of state attorneys general sued to block it, arguing it would raise prices. Regulators eventually approved the deal on the condition that assets, including Sprint's prepaid brand Boost Mobile, be sold to help Dish Network build a fourth network. Critics have continued to question whether that remedy preserved competition, and the merger remains a reference point in debates over telecom consolidation.

A US wireless carrier controlled by a foreign parent draws scrutiny from a national security angle. T-Mobile operates critical communications infrastructure, and Deutsche Telekom's majority ownership has historically required assurances to US authorities about network security and data handling. Any move by Deutsche Telekom to formally absorb T-Mobile would likely trigger fresh regulatory review, including from bodies that screen foreign control of sensitive US assets.

In 2026 Deutsche Telekom was reported to be exploring a full combination with T-Mobile US, a deal that would be one of the largest public mergers ever attempted, with the combined company valued at around $400 billion. Such a transaction would test how minority public shareholders are treated when a controlling parent moves to consolidate a company it already dominates. Governance experts often flag these situations, because the controlling owner and the minority holders can have conflicting interests over price. As of mid-2026 the discussions were described as early-stage and not final.

T-Mobile's status as a controlled company means it operates with fewer independent-governance protections than a typical public firm. Deutsche Telekom's ability to appoint most of the board and to vote SoftBank's shares concentrates decision-making. Supporters argue this gives T-Mobile a stable, committed long-term owner. Critics note that public shareholders have little recourse if the parent's interests diverge from their own.

Ownership defines who captures the value T-Mobile creates. The company has been one of the best performers in US telecom, adding customers and lifting revenue while rivals struggled. Because Deutsche Telekom owns the majority, most of that upside flows to the German parent and its shareholders, which include the German state. Public T-Mobile investors share in the growth, but they do so as minority holders in a business someone else controls.

Control also shapes strategy. Deutsche Telekom has treated T-Mobile as its most important asset and reinvested around it, from spectrum purchases to the Sprint merger to large share buybacks. Those buybacks have a second effect: by not participating fully in them, Deutsche Telekom lets its percentage ownership drift higher over time. The parent has used a mix of open-market purchases, option agreements, and buyback mechanics to march from a minority position to majority control without paying a single large premium.

For SoftBank, the story is about exit and redeployment. Its retreat from T-Mobile freed billions in capital that Masayoshi Son has poured into artificial intelligence, most visibly OpenAI. SoftBank's shrinking stake illustrates how a financial investor can use a telecom holding as a source of funding for entirely different bets, in contrast with Deutsche Telekom's strategic, long-term commitment to the wireless business.

For customers, ownership matters less directly, but it still shapes the product. A stable controlling owner has funded aggressive network investment and the Un-carrier pricing playbook that pressured rivals. At the same time, the reduction from four carriers to three, enabled by the ownership consolidation of the Sprint deal, gives the remaining players more pricing power. If Deutsche Telekom completes a full merger, the question of how a single foreign-headquartered owner runs a core piece of US telecom infrastructure will only grow sharper.

T-Mobile US is majority-owned by Deutsche Telekom, the German telecommunications company, which holds roughly 53% of the shares and controls close to 57% of the vote through a proxy agreement. T-Mobile is publicly traded on the Nasdaq under the ticker TMUS, so the remaining shares are held by public and institutional investors, but Deutsche Telekom is firmly in control.

Yes. T-Mobile US trades on the Nasdaq under the ticker TMUS. However, it is classified as a controlled company because Deutsche Telekom holds a majority of the voting power. Public shareholders own the economics of their shares but have limited influence over the company's strategy and board.

Srini Gopalan became chief executive officer of T-Mobile on November 1, 2025. He succeeded Mike Sievert, who led the company from 2020 and moved into the role of vice chairman. Gopalan previously served as T-Mobile's chief operating officer and had run Deutsche Telekom's German business before that.

Only a small amount. SoftBank received about a 24% stake when its Sprint unit merged into T-Mobile in 2020. It has since sold most of that position, including large sales in 2025 to help fund its investment in OpenAI. SoftBank's remaining stake is around 2.5%, and Deutsche Telekom votes those shares under a proxy agreement.

Deutsche Telekom built its majority gradually. It entered the US by acquiring VoiceStream in 2001, saw its stake fall to 43% after the 2020 Sprint merger, then bought shares from SoftBank and used option agreements and buyback dynamics to climb higher. It crossed the 50% threshold in 2023 to become the majority owner, and in 2026 it was reported to be exploring a full merger with the US unit.
