SpaceX announced an agreement on Thursday to purchase a nationwide spectrum portfolio as it pushes its Starlink service deeper into the U.S. telecommunications market. Shares of AT&T, Verizon and T-Mobile tumbled in extended trading.
The deal involves the acquisition of a spectrum portfolio from Grain Management, which specializes in digital infrastructure, and is subject to approval by the Federal Communications Commission. SpaceX said in a statement that it's a "license portfolio of up to 14 megahertz of paired spectrum in the 800 MHz band."
"This prime low-band spectrum addresses one of the key remaining technical gaps that will pave the way for Starlink Mobile to become a major mobile carrier in the US," SpaceX said.
In a post on X, SpaceX CEO Elon Musk called it a "very big deal."
The announcement comes a day after the FCC said it would vote on a proposal to auction 25 megahertz of "prime spectrum" to support direct-to-device, or D2D, services from satellites to smart phones. The FCC also said it would vote Oct. 29 on taking public comment on a proposal to make an additional 482MHz of spectrum available for supplemental coverage from space and to modernize FCC rules for D2D services in the licensed spectrum.
The two proposals could benefit SpaceX as well as Amazon, which has also moved to build a service with satellite networks.
Last week, T-Mobile, AT&T and Verizon formed a joint venture "focused on expanding coverage in underserved areas," via satellite and D2D services, and Starlink was notably absent. T-Mobile has also previously removed mention of Starlink from its T-Satellite promotions.
SpaceX appears determined to battle telecommunications giants in the U.S., and deliver its own services without them.
"This adds fuel to the fire in the battle between SpaceX and the mobile operators," said TMF Associates' Tim Farrar, an industry expert. "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."
