Crown Castle Stock Jumps 9% After Hours on Report SpaceX Wants 80,000 Cell Sites for a Fourth U.S. Carrier

SpaceX Reportedly Wants 80,000 Cell Sites — and Tower Stocks Just Lit Up

Short answer: Bloomberg reported Thursday evening, October 22, that SpaceX is in talks to secure access to at least 80,000 U.S. cell sites as it works to build a fourth nationwide wireless carrier — and Crown Castle (NYSE: CCI), named as one of the tower operators in the talks, jumped about 9% in after-hours trading while AT&T, Verizon and T-Mobile all fell.

Nothing has been signed and SpaceX has not confirmed the report. But the after-hours tape repriced the U.S. wireless map anyway: tower landlords were bid up as the likely winners of a SpaceX ground-network buildout, and the big three carriers were sold as the targets of a potential new nationwide rival.

What Happened

According to Bloomberg, cited by TheFly/TipRanks and Investor's Business Daily, SpaceX is negotiating access to at least 80,000 cell sites across the United States — roughly half of the approximately 158,500 purpose-built cell towers operating in the country last year, per Wireless Infrastructure Association figures cited in coverage of the report. Crown Castle, which operates about 40,000 U.S. towers, was named as one of the operators in discussions over tower leases.

The logic is straightforward: satellites alone cannot carry a national phone network. SpaceX's existing satellite-to-phone service, sold through T-Mobile as T-Satellite, runs on roughly 650 satellites at speeds around 4 Mbps — a coverage layer for texts and dead zones, not a network that can serve cities. A ground network of tower-mounted radios is the missing piece for building penetration and urban capacity, and SpaceX's own FCC filings acknowledge that deployment will rely on antennas mounted on towers, rooftops and other structures.

The report lands on top of two recent building blocks. On October 8, SpaceX said it planned to buy up to 14 megahertz of nationwide 800 MHz spectrum from Grain Management in a deal valued at roughly $8 billion, subject to regulatory approval. The FCC has also recently granted SpaceX approval to launch an additional 15,000 next-generation Starlink satellites for its Starlink Mobile service. On Tuesday night's earnings call, SpaceX management reaffirmed plans to become a major U.S. mobile operator combining satellites, cell towers and terrestrial locations already using Starlink broadband.

Why It's Blowing Up

The market reaction was immediate and two-sided. Crown Castle shot up about 9% in late trade — to roughly $86 after closing the regular session at $78.83, up just 0.2% — a move that would put it above its 200-day moving average. Fellow tower operators followed: American Tower (NYSE: AMT), which runs about 42,000 U.S. sites, climbed roughly 4–5%, and SBA Communications (NASDAQ: SBAC) gained about 7–8%.

On the other side of the trade, Verizon (NYSE: VZ), AT&T (NYSE: T) and T-Mobile US (NASDAQ: TMUS) fell roughly 3% to 5% in extended trading on fears of a well-funded fourth national competitor. SpaceX itself (NASDAQ: SPCX) edged about 1% higher after hours after diving 9.1% during Thursday's broader tech selloff.

There is also a hint the talks may have been hiding in plain sight: on Crown Castle's earnings call Wednesday, CEO Christian Hillabrant said the company was talking to "all parties" when asked about potential leases with SpaceX and Amazon, while declining to discuss specific customers.

Key Facts

The report: Bloomberg says SpaceX is in talks for access to at least 80,000 U.S. cell sites; Crown Castle is named among the tower operators involved
Crown Castle (CCI): Closed at $78.83 (+0.2%), then jumped about 9% after hours to roughly $86
Other tower stocks: American Tower up roughly 4–5% after hours; SBA Communications up about 7–8%
Carriers hit: AT&T, Verizon and T-Mobile fell roughly 3% to 5% in extended trading
Scale: 80,000 sites is about half of the ~158,500 purpose-built U.S. towers; Crown Castle operates ~40,000 towers, American Tower ~42,000 U.S. sites
The cost question: TD Cowen estimates a nationwide ground network could cost more than $80 billion and take many years to build
Status: Unconfirmed report — no deal has been announced and SpaceX has not commented

What's Next

The first test comes at Friday's open: headline-driven after-hours moves often fade if no confirmation follows, and this one rests entirely on unnamed sources. Watch for any statement from SpaceX, Crown Castle or the other tower operators, and for whether the Grain Management spectrum deal clears regulatory review — without spectrum and sites together, there is no fourth carrier. Analysts are also likely to press the funding question: a ground buildout on this scale would add tens of billions of dollars to SpaceX's spending plans, and TD Cowen's estimate tops $80 billion. For now, the story is a reported negotiation, not a signed lease — treat it that way.

Is SpaceX really building a fourth U.S. wireless carrier?

That is the reported ambition, but it is unconfirmed. No deal has been announced, SpaceX has not confirmed the talks, and analysts estimate a nationwide ground network could cost over $80 billion and take years to build.

Why did AT&T, Verizon and T-Mobile fall on the news?

How many cell towers does Crown Castle operate?

Crown Castle operates about 40,000 U.S. cell towers. American Tower operates roughly 42,000 U.S. sites, and the 80,000 sites SpaceX reportedly wants equal about half of all purpose-built towers in the country.
