SpaceX agreed Thursday to buy a nationwide spectrum portfolio from Grain Management, a move that sent shares of AT&T, Verizon and T-Mobile lower in after-hours trading and signals the satellite operator's intent to compete directly with the incumbent mobile carriers.
The spectrum and the stakes
The purchase covers up to 14 megahertz of paired low-band spectrum in the 800 MHz range, which SpaceX said fills a critical technical gap for its Starlink Mobile service to become a major U.S. carrier. The transaction requires Federal Communications Commission approval. Chief Executive Elon Musk described the agreement as a "very big deal" in a post on X.
Carrier response and analyst view
The announcement follows last week's formation of a joint venture by the three largest U.S. carriers to expand satellite-based coverage in underserved areas, a venture that notably excluded Starlink. T-Mobile has also scrubbed references to Starlink from its satellite marketing. TMF Associates' Tim Farrar said the deal intensifies the conflict with mobile operators, though he cautioned that 14 megahertz is a modest amount and reliable urban indoor coverage would still require a ground-based tower network.
Regulatory tailwinds
The FCC said Wednesday it would vote on a proposal to auction a 25-megahertz block of prime spectrum for direct-to-device satellite services, and on Oct. 29 it will consider opening a proceeding on an additional 482 megahertz and updated rules for supplemental coverage from space. Both proceedings could benefit SpaceX as well as Amazon's satellite ambitions.
Starlink's financial engine
SpaceX, which listed in June at a valuation exceeding $2 trillion, relies on Starlink as its sole profitable segment. The service operated in 205 countries with 12 million subscribers at the end of June, generating $1.66 billion of operating income on $4.29 billion of revenue in the second quarter. The constellation now exceeds 11,000 satellites. Deutsche Bank analysts, who rate the shares a buy, estimate the global subscriber base reached 13.5 million by the end of September, with 4.1 million in the United States.
Beyond satellites
The rocket business is shifting focus from Falcon to Starship, with a reduced launch cadence planned for next year as the company works toward full reusability. SpaceX is also investing in cloud computing and has outlined a long-term goal of orbital data centers, though its space and artificial intelligence units currently operate at a loss. Shares rose about 2.5 percent in extended trading after a 4 percent decline during the regular session.
