SpaceX Secures Spectrum Deal as Telecom Stocks Slide

SpaceX's push into the US wireless market intensified Thursday, October 8, 2026, when the company announced an agreement to acquire nationwide low-band spectrum licenses from Grain Management. The transaction, which requires Federal Communications Commission approval, aims to strengthen Starlink Mobile's coverage and position the satellite operator to compete with established telecommunications providers.

The agreement covers up to 14 megahertz of paired spectrum in the 800 MHz band. The Wall Street Journal reported that SpaceX agreed to pay $8 billion in cash, although the companies did not disclose financial terms in their announcements.

Shares of AT&T, Verizon and T-Mobile declined in extended trading following the announcement. In premarket trading Friday, AT&T fell 6.6% to $23, Verizon dropped 7.23% to $43, and T-Mobile lost 6.79% to $159.70, according to Forbes. SpaceX shares rose approximately 2.5% in extended trading Thursday and gained further in Friday's premarket session.

SpaceX said the acquisition would address a significant technical limitation in its planned mobile service. The 800 MHz frequencies can travel farther and penetrate buildings more effectively than higher-frequency signals, potentially improving connectivity in locations where satellite-based services face difficulties.

SpaceX described the acquisition as a way to close a remaining technical gap in its efforts to establish a major US mobile carrier.

Most existing mobile devices already support the 800 MHz band, according to SpaceX. However, compatibility with Starlink Mobile has not been confirmed for specific devices, including recent iPhone models.

Elon Musk also highlighted the transaction's importance in a post on X, calling it a "very big deal." The company has not announced when Starlink Mobile would launch if regulators approve the acquisition.

The agreement follows SpaceX's earlier spectrum acquisition from EchoStar, valued at $17 billion, which involved frequencies in the 2 GHz band. SpaceX has also received FCC approval for a plan to launch 15,000 next-generation Starlink Mobile satellites, which the company says could deliver more than "100 times the bandwidth of our current generation" to unmodified devices worldwide.

SpaceX's expansion comes as traditional wireless operators pursue alternative ways to extend coverage. CNBC reported that T-Mobile, AT&T and Verizon formed a joint venture the previous week focused on underserved areas through satellite and direct-to-device services. Starlink was not included in that initiative.

Despite the market reaction, analysts cautioned that spectrum alone would not give SpaceX a network capable of matching established carriers in densely populated areas. JPMorgan maintained its Overweight rating on SpaceX while noting that a competitive mobile operation would require substantial investment in ground infrastructure or an agreement allowing the company to use an existing carrier's network.

Tim Farrar of TMF Associates said the acquisition would intensify competition between SpaceX and established wireless operators, but emphasized the limitations of the available spectrum.

"But it's still a very limited amount of spectrum and to get reliable building penetration in urban areas SpaceX would have to deploy towers on the ground," Farrar said.

KeyBanc analyst Brandon Nispel viewed the acquisition as favorable for wireless tower operators, while Goldman Sachs expected SpaceX to use the 800 MHz spectrum with cell towers in major cities and other urban areas. American Tower, Crown Castle and SBA Communications each rose approximately 8% in Friday's premarket trading.

Executives at established carriers have previously questioned whether satellite-based connectivity can compete with terrestrial networks in urban and suburban markets. AT&T CEO John Stankey argued that direct-to-cell technology addresses the final portion of connectivity gaps rather than replacing existing infrastructure. Verizon CEO Dan Schulman similarly cited physical limitations affecting satellite services in densely populated areas.

Meanwhile, SpaceX continues to rely heavily on Starlink as its primary profitable business. CNBC reported that the service operated in 205 countries and had 12 million subscribers as of June 30, 2026. Its second-quarter results showed $4.29 billion in revenue and $1.66 billion in operating income, while Deutsche Bank analysts estimated that its global subscriber base reached 13.5 million by the end of September, including 4.1 million in the United States.

The FCC is also scheduled to vote October 29 on whether to seek public comment on a proposal to make an additional 482 megahertz of spectrum available for satellite-based supplemental coverage and update rules governing direct-to-device services.
