SpaceX to Buy 800 MHz Spectrum Portfolio for About $8 Billion in Cash
Key Facts
Grain Management announced on October 8, 2026, a definitive agreement under which SpaceX will acquire its entire nationwide portfolio of 800 MHz spectrum licenses in a deal valued at about $8 billion in cash, Reuters reported, citing a Wall Street Journal report. Grain did not disclose the financial terms of the agreement, while the company said SpaceX would buy 100% of the portfolio, a share that applies to the assets offered for sale and does not mean coverage of the same proportion of the U.S. population. The deal supports Starlink Mobile's efforts to offer direct-to-device connectivity combining terrestrial networks and satellite links. Grain said the agreement gives the service access to customers "from the ground and space." Closing remains subject to approval by the U.S. Federal Communications Commission and customary closing conditions.
The spectrum's importance stems from the characteristics of the low-frequency 800 MHz band: its signals travel long distances and penetrate buildings and tree cover, which could help extend connectivity in hard-to-cover areas. Starlink Mobile already holds global mid-band spectrum in the 2 GHz range, which is suited to providing high capacity, according to Reuters. The new band adds, according to the report, propagation characteristics different from those of mid-band spectrum, which could help signals overcome obstacles. Grain said the deal uses scarce low-band spectrum to support direct-to-device satellite services. The role of the new frequencies is therefore tied to a service combining satellite access with terrestrial coverage, rather than simply expanding the capacity of the existing satellite network.
The portfolio stems from a broader deal between Grain and T-Mobile: Grain said it acquired 800 MHz licenses from the company in August 2026 in exchange for cash and its own 600 MHz spectrum. The Federal Communications Commission approved a license exchange between the parties on July 1, 2026, involving the transfer of certain 800 MHz licenses from T-Mobile to Grain and certain 600 MHz licenses from Grain to T-Mobile. In its decision, the commission linked the performance of 800 MHz spectrum to requirements for direct-to-device connectivity services, and imposed terrestrial buildout conditions alongside incentives for Grain's partnership with operators of those services. These conditions show that spectrum use is tied to terrestrial deployment obligations and direct-to-device service performance, as well as completion of the ownership transfer. The SpaceX deal is also subject to the commission's approval, making the regulatory process part of the agreement's execution.
SpaceX is also building a terrestrial cellular network to support its connectivity plans: it selected Qualcomm to provide Dragonwing chips and network software under a multiyear agreement covering tens of thousands of cell sites. Deployment of those sites is expected to begin in 2027, according to Axios. SpaceX officials have said the company plans to launch its cellular phone service business in late 2027. This timeline puts site construction and service operation after the announcement of the spectrum purchase, while completion of the deal itself depends on approval by the Federal Communications Commission. The commission said SpaceX's planned deployment of the spectrum "could enhance competition in the wireless market" and expand service options, particularly for consumers in geographically hard-to-reach areas.
In the first trading session after the deal was announced, shares of AT&T, Verizon and T-Mobile closed down 9.8%, 8.8% and 13.3%, respectively, according to Axios. The moves came as SpaceX's plan puts the company on a path to enter the telecommunications market through a mix of terrestrial frequencies and satellite connectivity, while the planned network remains in preparation. On November 9, 2026, SPCX shares closed at $142.07, according to EL7 data. Grain founder and Chief Executive David Green said when the deal was announced that it "puts this capability in an exceptional range, with the potential to change where and how Americans connect." FCC approval, followed by the expected start of deployment in 2027 and the planned launch of the service in late that year, remain the next milestones for the project.
