Key takeaways:
- SpaceX agreed to acquire Grain Management’s nationwide 800 MHz spectrum portfolio, pending FCC approval.
- Low-band spectrum could improve Starlink Mobile coverage inside buildings and across remote areas.
- T-Mobile, Verizon and AT&T shares each fell about 6% in extended trading.
SpaceX agreed Thursday to acquire a nationwide portfolio of low-band wireless spectrum from private-equity firm Grain Management, strengthening Starlink Mobile’s push to challenge U.S. cellular carriers with satellite connectivity that reaches indoors and across remote areas.
SpaceX acquires low-band spectrum to expand mobile coverage
The SpaceX wireless spectrum deal covers 100% of Grain Management’s nationwide 800-megahertz spectrum portfolio. The companies did not disclose financial terms, although The Wall Street Journal reported that SpaceX would pay about $8 billion in cash, citing people familiar with the matter.
SpaceX’s Starlink Mobile service already uses 2-gigahertz mid-band spectrum to provide satellite-to-cellular connectivity. The newly acquired airwaves could help extend coverage because low-band frequencies travel longer distances and penetrate buildings and tree cover more effectively.
The combination could allow SpaceX to compete more directly with traditional wireless providers, including T-Mobile, Verizon and AT&T. Most existing mobile handsets support the 800-megahertz band, potentially allowing customers to connect without buying specialized satellite phones.
The transaction still requires approval from the Federal Communications Commission. Grain acquired the spectrum from T-Mobile earlier this year.
Wireless stocks fall as carriers face new competition
Shares of T-Mobile, Verizon and AT&T each fell about 6% in extended trading Thursday following news of the agreement, reflecting investor concerns about increased competition from satellite-based mobile services.
The SpaceX wireless spectrum deal could expand Starlink Mobile beyond its role in providing connectivity in remote areas where conventional cellular coverage is limited. SpaceX is positioning the service as a potential alternative to terrestrial networks, although its ability to match established carriers’ coverage and reliability remains uncertain.
Analysts at William Blair said established wireless companies have questioned whether SpaceX can deliver network quality comparable to their own.
The analysts also expect SpaceX to offer competitive packages combining Starlink broadband and Starlink Mobile. Such bundles could potentially include Grok, the artificial intelligence chatbot developed by Musk’s xAI.
Verizon spokesman Rich Young said acquiring spectrum alone would not guarantee a competitive network.
“This company can have tons of spectrum available, but if they do not have the network to use it, it doesn’t matter. It’s just empty airwaves,” Young said.
The three major carriers formed a satellite-focused joint venture in May, a move analysts have viewed as a possible response to growing competition from SpaceX.
FCC approves Starlink Mobile’s 15,000-satellite plan
The FCC also approved Starlink Mobile’s Gen2 constellation application this week, authorizing SpaceX to launch 15,000 satellites optimized for 2-gigahertz spectrum worldwide.
The planned satellites will operate in very low Earth orbit, with the goal of expanding bandwidth and reducing connection delays for standard mobile devices. The authorization adds to SpaceX’s efforts to build a satellite network capable of serving consumers beyond the reach of conventional cell towers.
FCC Chair Brendan Carr welcomed the SpaceX wireless spectrum deal, saying it could encourage investment and competition in the U.S. communications market.
“We are going to see more investment, more opportunities for a range of providers, and America leading the world in next-gen technologies — to the benefit of consumers all across the country,” Carr said.
Grain Management CEO David Grain said the transaction has “the potential to change where and how Americans connect.”
The deal marks a significant step in SpaceX’s effort to combine satellite infrastructure with spectrum suited to mobile communications. Its success will depend on regulatory approval, network deployment and its ability to compete with established carriers on coverage, service quality and price.
