SpaceX has made explicit its intent to extend Starlink beyond satellite-only connectivity and develop a full mobile service using spectrum the company acquired from EchoStar. The purchases, completed through two deals announced last year, amount to 65 megahertz of wireless licenses and cost $19.6 billion in total.
Speaking on a post-earnings call, SpaceX President Gwynne Shotwell said the EchoStar spectrum "does have terrestrial components, so we definitely intend to build out terrestrial." She added that the company will construct the infrastructure required to turn Starlink into "a true mobile service" and that it expects to win "quite a few" customers from the Big Three U.S. wireless carriers - Verizon, AT&T and T-Mobile.
The remarks represent SpaceX’s clearest statement to date that it plans to pair its satellite network with ground-based assets, moving beyond Starlink’s current direct-to-device offering designed for areas without cellular coverage. The comment came as markets digested the implications of the spectrum purchases and the company’s broader connectivity ambitions.
Investors reacted quickly. Shares of Verizon, AT&T and T-Mobile slid in after-hours trading, falling in a range between 2.2% and 4% as traders assessed the competitive implications of SpaceX’s statements.
Starlink and SpaceX’s connectivity businesses remain a central source of cash flow for the company, underpinning Chief Executive Elon Musk’s investments in other capital-intensive initiatives cited on the call, including work on artificial intelligence, data centers and next-generation rockets.
Analysts urged caution in expecting rapid disruption. They emphasized that converting Starlink into a nationwide wireless provider would not be simple, and would likely demand years of heavy investment and execution. The established carriers have built substantial advantages over decades. They have spent hundreds of billions of dollars across roughly three decades to acquire spectrum, construct and upgrade network infrastructure, and spend heavily to attract and retain subscribers - advantages industry analysts say would be difficult for SpaceX to replicate quickly.
Craig Moffett of MoffettNathanson highlighted a specific commercial hurdle. He said that "unless Starlink can secure an MVNO (Mobile Virtual Network Operator) agreement from one of the carriers, which would provide a baseline of coverage, it’s extraordinarily challenging to imagine a direct-to-consumer service from Starlink that could be competitive with carrier services in the next five years." An MVNO leases network capacity from an existing carrier rather than owning a nationwide cellular network, giving it baseline coverage without a full terrestrial footprint.
Shotwell declined to provide a detailed cost estimate for the buildout, saying only that SpaceX has "great and new ideas" it believes will be capital efficient. That comment underscored the company’s intent to pursue approaches it perceives as cost-effective rather than replicating the large-scale terrestrial investments made by incumbents.
Not all market participants view the situation the same way. David Barden of New Street Research cautioned that the scale of the incumbents’ spectrum holdings remains a practical limit. He said, "It makes no sense for SpaceX to try to replicate what terrestrial players have built over 30 years with 1000 MHz between them, with 65 MHz."
Other investors said the market might be underestimating SpaceX’s potential to change the competitive landscape. David Wagner, portfolio manager at Aptus Capital Advisors, said he agreed with Musk’s assertion on the call that investors may have undervalued the connectivity business. Wagner also warned that traditional carriers could be at risk of being outpaced by SpaceX’s appetite for innovation.
Separately, under its existing partnership with T-Mobile, SpaceX already uses Starlink satellites to deliver direct-to-cell connectivity for compatible smartphones outside of conventional cellular coverage, a capability that complements rather than directly replaces carrier networks.
Context and next steps
SpaceX’s public intention to build terrestrial infrastructure around Starlink crystallizes a potential new frontier in U.S. wireless competition. Whether the company can translate spectrum ownership and satellite capability into a broadly competitive mobile offering will hinge on contract access to terrestrial coverage, capital deployment and multiyear execution against entrenched carrier advantages.
