SpaceX Plans to Connect 80,000 Cell Towers, Positioning as the Fourth-Largest U.S. Wireless Carrier

SpaceX is negotiating with major U.S. tower companies to connect to at least 80,000 cell sites, aiming to turn Starlink into a full-fledged fourth nationwide wireless carrier — a direct challenge to AT&T, Verizon, and T-Mobile.
80,000 cell sites — whose towers is SpaceX renting?
SpaceX has entered talks with Crown Castle, one of the three largest tower-asset owners in the U.S., alongside American Tower and Vertical Bridge.
Crown Castle CEO Chris Hillabrant, asked on a Wednesday earnings call whether the company was in discussions with SpaceX, said: "You can assume we are talking to all relevant parties." He declined to name specific clients.
This means → SpaceX is not probing — it is running parallel negotiations with multiple tower firms. Bloomberg estimates the potential deal value could reach billions of dollars.
Why rent towers instead of building its own?
Wireless networks rely on antennas mounted on towers — cell sites — spread across the country. AT&T, Verizon, and T-Mobile all lease tower space rather than build, because sharing infrastructure is far cheaper.
In plain terms = towers are like toll booths on a highway — anyone can pay to drive on; building your own road costs more. SpaceX is taking the same approach.
This reflects a speed play: SpaceX wants a nationwide ground-signal network fast, and leasing is the shortcut.
What cards does Musk hold?
On SpaceX's earnings call, Musk stated explicitly: "We will build out the terrestrial network" — and that satellite launches plus spectrum acquisition will "pave the way" for Starlink Mobile to become a major carrier.
SpaceX recently acquired low-band spectrum — radio frequencies that penetrate buildings and cover wide areas — a license-grade asset essential for any mobile carrier.
The FCC has approved SpaceX to launch 15,000 satellites designed specifically for direct-to-phone service. This means → satellites above, cell sites below, spectrum in hand — the three pieces of the puzzle are converging.
Have tower stocks already priced this in?
Tower company shares rose after SpaceX announced the spectrum acquisition earlier this month — the market is betting they will win sizable orders from SpaceX's infrastructure buildout.
Crown Castle's CEO called SpaceX's low-band spectrum purchase an "important milestone" for broad coverage — unusually bullish language.
In plain terms = tower firms are "the people selling shovels" — whether or not SpaceX ultimately becomes the fourth carrier, the tower-rental checks are already being written.
Where is the biggest uncertainty?
Research firm MoffettNathanson flagged a key risk: SpaceX plans to use home broadband devices to broadcast mobile signals to nearby users, but those devices sit wherever existing subscribers happen to live — not necessarily where a stable network needs coverage.
This means → if current Starlink users cluster in suburbs and rural areas, urban cores could have signal gaps.
The actual pace of ground-network buildout is the make-or-break test for the "fourth carrier" ambition.
