SpaceX buys nationwide spectrum in push to become a mobile carrier

Overview

Updated 2 hours ago

SpaceX agreed to pay about $8 billion in cash for nationwide cellular spectrum licenses, its biggest move yet into the business of phone service. The airwaves sit in the 800-megahertz band, the kind used by cell towers rather than satellites.

The deal gives Starlink's satellite-to-phone service a way to reach devices inside buildings, where satellite signals can't pass. It also sets SpaceX up as a potential fourth U.S. carrier, and shares of AT&T, Verizon, and T-Mobile fell more than 6 percent after hours when the news broke. The purchase still needs approval from the Federal Communications Commission (FCC).

Why it matters

SpaceX is pursuing a fourth U.S. mobile carrier. Three companies control nearly all wireless service—success would change that market structure.

Scenarios

FCC approves SpaceX's spectrum purchase

Likely Resolves by Q2 2027

Discussed by: Ars Technica and industry analysts; Rural Wireless Association opposes similar consolidation

The FCC reviews the license transfer and issues a final order approving it, possibly with conditions. Rural carriers have opposed recent spectrum deals by AT&T and SpaceX, arguing they hurt rural providers. Most analysts expect approval, given the FCC already approved Grain's purchase of the same licenses this summer.

SpaceX signs an MVNO deal with a big-three carrier

Possible Resolves by End of 2027

Discussed by: Craig Moffett of MoffettNathanson

SpaceX uses the spectrum purchase to get a big carrier to the table, signing a mobile virtual network operator (MVNO) agreement to sell phone service over a partner's network. Moffett argues this is the only realistic path to competing with the big three, and that buying low-band spectrum is partly leverage to force such a deal.

SpaceX builds a terrestrial network and launches standalone service

Unlikely Resolves by End of 2029

Discussed by: JPMorgan analysts (skeptical); UBS

SpaceX builds towers and small cells to use the low-band spectrum itself, launching a Starlink Mobile service that competes head-on with the big three. JPMorgan says this would take years of infrastructure and capital, and UBS notes low-band alone can't reach inside some buildings. The FCC requires construction benchmarks for the licenses, which would force a buildout timeline.

Historical Context

3 moments from history that rhyme with this story — and how they unfolded.

November 1998 - August 1999

Iridium satellite phone network (1998-1999)

Iridium launched 66 satellites and began selling satellite phone service worldwide in late 1998, backed by Motorola and other investors. The service had strong technology but high prices, bulky handsets, and poor in-building coverage.

Then

Iridium filed for Chapter 11 bankruptcy in August 1999, months after launch.

Now

The failure became the standard case study in why satellite service can't beat terrestrial cellular on cost or convenience.

Why this matters now

Today's satellite-to-phone services face the same core problem Iridium did: signals that can't reach indoors. That's exactly why SpaceX is buying low-band terrestrial spectrum.

2012 - 2020s

Dish Network's wireless buildout (2010s-2020s)

Dish spent billions amassing a national spectrum portfolio without operating a mobile network. Regulators tied its 2020 approval of the T-Mobile-Sprint merger to Dish building a new network. It spent years and billions constructing one.

Then

Dish (later EchoStar) built a 5G network but struggled to gain subscribers and remained the perennial 'maybe fourth carrier.'

Now

The lesson: owning spectrum is not the same as operating a network, and scarce subscribers are the harder half of the problem.

Why this matters now

Verizon's comment that SpaceX's airwaves could be 'just empty airwaves' echoes Dish's experience. Spectrum alone hasn't made anyone a viable fourth carrier yet.

2017 - present

Comcast and Charter enter wireless as MVNOs (2017)

Rather than build networks, cable giants Comcast and Charter launched mobile services by renting capacity from Verizon under MVNO agreements. They marketed service as a bundle with home internet.

Then

Comcast's Xfinity Mobile and Charter's Spectrum Mobile added millions of subscribers without owning a tower.

Now

They became modest but real competitors, proving the MVNO path works—if a carrier will rent you its network.

Why this matters now

This is the route MoffettNathanson says SpaceX must take. The difference: SpaceX has a satellite network to pair with a rented terrestrial one, something no MVNO has had before.
