The company that spent a decade trying to make cell towers irrelevant now wants to rent 80,000 of them.

Reuters reported Thursday, citing Bloomberg News and people familiar with the matter, that SpaceX is in talks with cellular infrastructure companies to secure access to at least 80,000 cell tower sites across the United States. If those deals land, they would firm up SpaceX's path toward becoming a fourth nationwide wireless carrier. The company is also in the process of buying nationwide low-band spectrum, and mobile infrastructure provider Crown Castle — which operates roughly 40,000 US towers — is reportedly one of the parties at the negotiating table.

Wall Street read the report exactly the way you'd expect. Shares of AT&T, Verizon, and T-Mobile all fell between 4.2% and 5% in extended trading on Thursday and stayed down in Friday's premarket session, while Crown Castle jumped more than 6% and American Tower also gained. European carriers slid too, with Deutsche Telekom dropping over 3%. As Dow Jones Newswires put it, this would be the first credible threat to the big three's dominance since T-Mobile's 2020 acquisition of Sprint.

None of the companies involved confirmed anything. SpaceX, Crown Castle, American Tower, and Vertical Bridge all declined to respond to Reuters. But Crown Castle CEO Christian Hillabrant said on Wednesday's earnings call that the company was talking to "all parties" when asked about leases with SpaceX and Amazon — a non-denial if there ever was one.

The sheer scale of the ambition is worth sitting with. TD Cowen estimated a nationwide terrestrial network would cost more than $80 billion and take many years to build, and the 80,000 sites SpaceX is reportedly targeting equal about half of America's 158,500 purpose-built cell towers, according to the Wireless Infrastructure Association.

Here's what makes this more than a rumor about tower leases: it inverts the entire Starlink thesis. SpaceX's satellite network was supposed to route around the ground game — beaming connectivity from orbit to places the carriers couldn't reach. Instead, Musk's path into the wireless business looks like the most conventional telecom move imaginable: rent the towers, buy the spectrum, and compete with AT&T and Verizon from inside their own playbook. It's the second giant strategic expansion this month for a company that just posted record profits from renting GPUs to its rivals — rockets, satellites, AI data centers, and now, apparently, your phone plan.

Watch what happens next: whether Crown Castle names SpaceX on a future earnings call, what spectrum deal SpaceX is actually closing, and how regulators react to a new nationwide carrier backed by the world's most valuable private company.
