SpaceX Pursues 80,000 Cell Sites to Build Fourth US Wireless Carrier

SpaceX is pursuing lease agreements for a minimum of 80,000 cell sites across the United States as the company advances its plans to establish a fourth nationwide wireless carrier, Stocktwits reported. The move places pressure on established mobile network operators while drawing mixed reactions across financial markets, with Citi analysts warning of substantial valuation risks for major telecom incumbents.

The reported push for cell infrastructure follows SpaceX’s recent acquisition of low-band spectrum designed to integrate Starlink satellites directly into a terrestrial mobile network. According to a Bloomberg report cited by Stocktwits, SpaceX has approached at least one major cellular infrastructure provider, including Crown Castle Inc., as the company weighs a costly terrestrial buildout to complement its satellite constellation.

Carrier Pushback and Regulatory Friction

Established U.S. wireless carriers are actively pushing back against the expansion of satellite-to-phone services. In an October 20 meeting with Federal Communications Commission officials, major carriers represented by the trade group CTIA urged the agency to exclude two key 5G spectrum bands from upcoming draft rules.

The carriers argued that expanding satellite access into those bands would create interference risks for existing terrestrial networks used by more than 300 million people. They also asked the FCC to maintain mandatory rules requiring satellite operators to reach commercial agreements with existing carriers before utilizing licensed spectrum.

Analyst Outlook and Financial Market Impact

Financial institutions have divergent views on how a new SpaceX wireless network would impact the broader telecommunications sector. Citi analysts characterized the infrastructure negotiations as a net positive for tower operators such as Crown Castle, SBA Communications, and American Tower.

At the same time, Citi estimated valuation risks ranging between 29% and 32% for AT&T, T-Mobile, and Verizon, with an additional 4% to 16% potential downside following recent pullbacks in 2026. Conversely, Scotiabank took a different view on satellite competitors, upgrading AST SpaceMobile to Outperform from Sector Perform and lifting its price target to $55.70 while describing the current stock valuation as an attractive opportunity.

Infrastructure Leasing and Deployment Logistics

An 80,000-site objective represents roughly half of the purpose-built cell towers operating across the United States, though industry reports note that the term cell sites can encompass macro towers as well as smaller installations. Logistics Viewpoints noted that a national terrestrial build could require tens of billions of dollars and face complex deployment hurdles involving municipal rules, landlord agreements, and electrical upgrades.

Roth Capital analyst Scott Searle pointed out that a large-scale terrestrial buildout by SpaceX would benefit a wide range of equipment, backhaul, and spectrum suppliers, including Ericsson, Nokia, Aviat Networks, Ceragon Networks, Anterix, NextNav, and Gogo. Meanwhile, SPCX shares closed nearly 2% higher at about $147.50 on Friday, supported by extremely high retail message volume and bullish sentiment on Stocktwits.

Unresolved Questions and Future Outlook

As negotiations continue, key questions remain regarding whether SpaceX will secure the necessary infrastructure or ultimately reach a resale partnership with incumbent operators. Executives for AT&T, T-Mobile, and Verizon have so far declined the mobile virtual network operator idea, and Crown Castle CEO Chris Hillabrant stated during an earnings call, You can assume that we’re talking to all parties, without disclosing specific customer discussions.
