SpaceX agrees to buy Grain spectrum for Starlink Mobile, pending FCC approval
The nationwide 800 MHz portfolio would support a network combining ground infrastructure and satellites. Consumer launch timing, prices and tested performance remain unspecified.
SpaceX has agreed to buy Grain Management’s nationwide US 800 MHz spectrum portfolio, Grain announced on 8 October 2026, adding airwaves intended to support Starlink Mobile connections from both ground infrastructure and satellites. The transaction still requires Federal Communications Commission approval and other closing conditions before the transfer can be completed.
Reuters reported on 9 October that the purchase covers up to 14 megahertz of paired spectrum and is reportedly valued at $8 billion. Grain’s announcement does not disclose a purchase price. The agreement concerns the entire portfolio, rather than a completed mobile network or a service already available to customers.
What 800 MHz spectrum could add to Starlink Mobile
Low-band spectrum consists of airwaves that travel farther and penetrate buildings better than higher frequencies, according to Reuters’ explainer. Those properties make it useful for broad-area mobile coverage. Mid- and high-band spectrum can carry more data at faster speeds, but cover smaller areas.
For Starlink Mobile, the plan is a hybrid network combining terrestrial infrastructure with satellite connectivity. Reuters reports that SpaceX intends to integrate the spectrum into its next-generation satellite system while deploying ground-based radios and antennas on towers and rooftops. These are plans for deployment, not evidence of completed construction.
Grain describes the intended use as supporting satellite direct-to-device services, with customers reached from both the ground and space. The general advantages of low-band frequencies do not establish how well this particular network would work indoors: neither report provides measured indoor performance for the proposed combined system.
FCC approval remains a condition of the purchase
Commercial spectrum in the United States is regulated by the FCC, which typically assigns licences for particular frequencies and geographic areas through auctions or other authorised processes, Reuters explains. Licence holders must follow technical rules and deployment requirements, while transfers generally require regulatory approval.
Grain’s transaction announcement explicitly makes the SpaceX sale conditional on FCC approval and other customary closing conditions. Neither Grain nor Reuters establishes an approval timetable. Signing the agreement therefore marks a proposed change in ownership, with the regulatory transfer decision still outstanding.
A separate satellite approval concerns another part of the planned system. Reuters reports that the FCC approved Starlink Mobile’s Gen2 constellation application during the week of 9 October, authorising 15,000 satellites optimised for 2 GHz spectrum worldwide. That authorisation does not establish that the satellites have launched or that the Grain licence transfer has been approved.
How Grain acquired the nationwide portfolio
Grain says it acquired the 800 MHz portfolio from T-Mobile in August 2026, exchanging cash and its own 600 MHz spectrum. The proposed SpaceX transaction follows that earlier acquisition, placing the same nationwide portfolio at the centre of a plan to combine satellite and terrestrial connectivity.
According to Grain, the FCC’s July order approving its acquisition from T-Mobile established a competitive selection process and a conditional pathway for direct-to-device deployment. That earlier decision concerned Grain’s purchase; it is distinct from the approval now required for SpaceX to acquire the portfolio.
“Spectrum is a finite resource with an expanding role in the economy,” Grain founder and chief executive David Grain said in the announcement. His statement sets out the seller’s rationale for the transaction as ground and space-based networks converge, rather than demonstrating a customer service outcome.
Where Starlink Mobile would fit in the US market
Low-band spectrum already features in the holdings of the three major US wireless carriers. Reuters lists AT&T’s holdings as including 700 MHz and 850 MHz spectrum, plus 600 MHz licences acquired through its July EchoStar deal. Verizon holds 700 MHz and 850 MHz spectrum; T-Mobile holds 600 MHz and 700 MHz spectrum.
Reuters says SpaceX first disclosed plans to enter mobile services during its inaugural earnings call in August. That announcement briefly weighed on shares of AT&T, T-Mobile and Verizon as investors assessed potential competition. The reported market reaction relates to the August announcement, rather than the October spectrum agreement.
What remains unknown for prospective customers
Neither report supplies a consumer launch date, subscription price, detailed rollout timetable or device compatibility information for the proposed combined network. FCC approval and closing remain necessary steps for the purchase, while the reported plans for ground infrastructure leave construction requirements unspecified. The agreement establishes SpaceX’s intended spectrum acquisition, but does not yet give customers a timetable for using the resulting service.
