SpaceX rises 4% on spectrum deal as Verizon and AT&T fall 7%

SpaceX shares climbed 4% to $166.89 in morning trading after the company announced it would acquire a nationwide low-band spectrum portfolio. The move positions Starlink to operate as a standalone cellular network in the United States, a shift that triggered a sharp selloff in established wireless carriers. Verizon Communications shares dropped 7% to $43, while AT&T stock fell 7% to $22.97 as investors priced in a new, well-funded competitor for subscribers.

The carrier decline occurred against a backdrop of a slightly stronger broad market, with the SPDR S&P 500 ETF Trust up 0.38%. The Communication Services Select Sector SPDR ETF remained flat, reflecting its heavier weighting toward large internet platforms rather than traditional carriers.

SpaceX stated late Thursday that the spectrum purchase allows Starlink to move beyond its current role as a direct-to-cell add-on for existing providers. Low-band spectrum is critical for this transition because its ability to penetrate buildings makes satellite-based service competitive against terrestrial networks. This acquisition represents a significant step for a company previously defined by satellite broadband, pushing it deeper into the cellular business long controlled by incumbent carriers.

The company’s mobile ambitions have been building since it secured U.S. spectrum through an approved EchoStar license transfer and established international partnerships with SoftBank, NTT Docomo, and Spark NZ. However, the nationwide coverage provided by this new deal transforms those partnerships into a direct head-to-head threat. SpaceX is vertically integrated across launch, spacecraft, and broadband, owning the constellation itself. In contrast, Verizon and AT&T rely on terrestrial networks and licensed spectrum. By purchasing land-based spectrum, SpaceX can now reach the same subscribers from a different asset base.

Market sentiment is divided on the immediate impact. The bear case centers on the competitive risk posed by a well-capitalized rival entering the market, which could pressure customer bases over time even if reported results remain unchanged in the short term. Conversely, the optimistic view notes that building a nationwide network requires significant time and capital, leaving carrier subscriber bases intact in the near future. AT&T Chief Executive John Stankey, speaking at the Goldman Sachs Communacopia conference in September, previously described satellite service as partly complementary through wholesale, highlighting its utility for airlines, rural areas, and connected vehicles.

Investors are now watching for details on Starlink’s rollout timing, device support, and pricing to determine if the carrier selloff will deepen or fade. T-Mobile faces similar competitive questions, and any response from the major carriers regarding pricing or satellite partnerships could reshape the landscape. The market is currently repricing competitive risk ahead of any actual changes in subscriber numbers, suggesting a multiyear contest for wireless dominance.
