SpaceX agreed to acquire a nationwide portfolio of 800 MHz spectrum licenses from investment firm Grain Management, the company announced on October 8, 2026. The deal covers up to 14 MHz of paired low-band spectrum and would fill what SpaceX calls one of the last major technical gaps in its plan to turn Starlink Mobile into a major US mobile carrier, competing directly with AT&T, Verizon, and T-Mobile.
The companies did not disclose a price. When SpaceX and rival AST SpaceMobile were reported to be competing for the same licenses in August, the portfolio was valued at roughly $6 billion; the Wall Street Journal, cited by Reuters, put the agreed deal at about $8 billion. Grain built much of the portfolio from 800 MHz holdings that T-Mobile sold off after its merger with Sprint. The transfer still requires approval from the Federal Communications Commission and other closing conditions.
In the same week, the FCC separately authorized Starlink Mobile's second-generation constellation: 15,000 satellites for global 2 GHz service. SpaceX says the Gen2 satellites will deliver more than 100 times the bandwidth of the current fleet, enabling high-speed service directly to unmodified phones. The regulator also cleared backhaul bands for SpaceX's V3 broadband satellites to connect with Starlink's existing gateway network.
Spectrum is the invisible real estate of wireless networks, and low-band frequencies are the most valuable kind for coverage. The 800 MHz band travels farther from a single tower and passes through walls, roofs, and dense foliage far better than the higher frequencies used for ultra-fast 5G in cities. That is exactly the hole in Starlink's model: satellite signals work well outdoors with a clear view of the sky but struggle to reach a phone in a kitchen, an office cubicle, or a parking garage.
The acquisition completes a two-layer design. Starlink Mobile already holds mid-band 2 GHz capacity from an earlier deal with EchoStar, which carries high-bandwidth traffic from satellites. The new 800 MHz layer adds the coverage that gets through obstacles — and, crucially, the 800 MHz band is supported by most phones already in people's pockets, so no special hardware would be needed. Once the FCC signs off, SpaceX plans to fuse the satellite-to-phone constellation with a ground-based terrestrial network, describing Starlink Mobile as the first operator to run both satellite and terrestrial spectrum as one system.
The market took the threat seriously. Shares of AT&T, Verizon, and T-Mobile fell roughly 6% in after-hours trading after the announcement, and Canadian carriers BCE, Rogers, and Telus slid between 3.5% and 5.5% on concerns that Starlink Mobile could pressure wireless margins beyond the US as well.
The deal is not done until regulators bless it, and a license is not a network. SpaceX still has to build out the terrestrial portion of the system and integrate it with its satellite constellation before any of this coverage exists commercially. FCC approval of the license transfer is the first gate, and the Gen2 satellite buildout will run on its own multi-year timeline.
If it all lands, the shift is bigger than better coverage in remote areas. Starlink would stop being a satellite service you reach for when cellular coverage is unavailable and become an everyday mobile network — one connection indoors, outdoors, and in cellular dead zones. For the incumbent carriers, that turns a roaming partner into a direct competitor; for regulators, it raises fresh questions about how much spectrum one company should control across both space and ground.
