SpaceX’s $8 billion spectrum buy still far from rivaling US telecom giants

SpaceX has secured roughly $8 billion for 800 MHz of U.S. spectrum licenses, describing the deal as a critical milestone for its planned Starlink Mobile offering, which will combine satellite connectivity with a terrestrial component. The firm intends to file for up to 15,000 satellites and install ground antennas on towers and rooftops, pursuing a hybrid architecture rather than a pure satellite-to-phone model. Analysts stress that urban mobile service presents technical hurdles—small phone antennas, limited power, and the need for dense ground infrastructure—that the company has never built, and that the cost could exceed $80 billion.

Comparisons to the $650 billion capex the three major carriers spent in the decade before 2023 highlight the scale of the challenge. While a partnership with an existing carrier as an MVNO is possible, insiders say no major operator is likely to offer wholesale access, leaving SpaceX to develop its own network. Executives from T-Mobile and Verizon have dismissed the spectrum purchase as insufficient to match existing network capacity.
