SpaceX Spectrum Deal Sends Telecom Stocks to Historic Lows

A proposed expansion into cellular service by SpaceX triggered a sharp sell-off across the U.S. telecommunications industry Friday, October 9, 2026, after Elon Musk's company announced plans to acquire nationwide radio spectrum. The deal could help Starlink move beyond satellite connectivity and compete more directly with established wireless carriers, although analysts warn that building a nationwide network will require substantial additional investment.

According to CNBC, Verizon shares fell 8.75%, marking their worst trading day since July 2002. T-Mobile dropped 13.27%, its steepest decline since 2013, while AT&T lost 9.81%, its worst session since 2000. SpaceX shares rose approximately 1%.

The agreement involves spectrum owned by Grain Management, including up to 14 megahertz of paired spectrum in the 800 MHz band. SpaceX described the acquisition as part of its strategy to expand Starlink Mobile, which aims to provide cellular coverage using satellites and ground-based radio equipment.

PCMag reported that Musk characterized the approximately $8 billion acquisition as the "last critical piece" needed to deliver "complete phone coverage in America." SpaceX previously acquired another portion of radio spectrum from EchoStar, the parent company of Boost Mobile.

SpaceX also has regulatory approval to launch 15,000 next-generation satellites for a second version of Starlink Mobile, according to PCMag. The planned system promises 5G connectivity at 150 Mbps per user, while the existing service operates with approximately 650 satellites.

Federal Communications Commission Chairman Brendan Carr welcomed the prospect of increased competition, although regulators must still oversee the spectrum transaction.

"really good news for the American consumers" was how Carr characterized competition in the spectrum market during an interview with CNBC.

Carr said the market could see a substantial increase in available spectrum over the next two years.

"We're probably going to bring over $100 billion of spectrum into the market over the next two years, so we're seeing a lot of competition," Carr told CNBC's Squawk on the Street on Friday.

He said companies would have to compete through innovation and market performance, leaving consumers to determine which services succeed.

"There's going to be moves in the market. People are going to try to out-compete, out-innovate, and I think that's great. We're going to see how this plays out. It's not for us ultimately to pick winners and losers," Carr added.

SpaceX also argued in a filing with the FCC that the acquisition would broaden mobile access nationwide.

"will supercharge competition in the mobile market by ensuring all Americans have access to high-speed mobile broadband anywhere they go," SpaceX said in its filing, as quoted by PCMag.

T-Mobile Chief Technology Officer John Saw questioned whether spectrum alone would enable SpaceX to match the performance of established wireless networks. In a LinkedIn post, he emphasized the extensive infrastructure required to serve customers across different environments.

"Great wireless networks aren't built with headlines or spectrum licenses alone. They're built site by site, neighborhood by neighborhood, in subway tunnels, office buildings, stadiums, and communities across America," Saw wrote.

Saw said Starlink Mobile would have approximately 80 MHz of spectrum following the acquisition, including some capacity limited to uplink use, compared with T-Mobile's nearly 400 MHz of mid-band and low-band spectrum.

"Even with this acquisition, Starlink Mobile would have roughly 80MHz of spectrum, some of it uplink-only. Compare that to T-Mobile's nearly 400MHz of mid-band and low-band spectrum holdings," Saw said.

He also argued that serving customers inside buildings and crowded venues presents a challenge for satellite-based connectivity.

"at home, in the office, inside a store, or at a crowded venue," Saw wrote, describing where much mobile traffic originates.

The executive said geographic coverage does not automatically translate into the performance customers expect from advanced cellular networks.

"Covering a geographic area is one thing. Delivering the speed, responsiveness, and capacity customers expect from a modern 5G-Advanced network is another," Saw wrote.

Despite his criticism, Saw acknowledged SpaceX's achievements and described satellite services as a potential partner to conventional wireless infrastructure.

"tremendous respect for what SpaceX has accomplished in space," Saw wrote.

He also described satellite connectivity as a complementary service rather than solely a rival to terrestrial networks.

"complement" was the term Saw used to characterize satellite connectivity's relationship with traditional cellular service.

Saw cited the industry's existing financial commitment as evidence of the scale of investment required to compete nationwide.

"The US wireless industry has invested more than $250B in network infrastructure since 2018. That’s on top of more than $200B in spectrum auctions over the past decade, plus the stores, care, and distribution that support customers every day. And that investment represents only part of what it takes to deliver a great wireless experience," Saw wrote.

Other market participants also questioned SpaceX's ability to close the infrastructure gap quickly. According to PCMag, UBS estimated that SpaceX held approximately 77 MHz of spectrum, below the roughly 300–350 MHz held by other U.S. carriers.

"well below the ~300-350MHz held" by other U.S. carriers, UBS said in its assessment of SpaceX's spectrum position.

The investment firm cautioned that expansion would take time and that the immediate impact on established carriers could remain limited.

"we still believe it will take time for SpaceX to scale its wireless ambitions, and the impact on near-term wireless industry fundamentals is limited," UBS added.

BNP Paribas Equity Research senior analyst Sam McHugh also questioned whether the newly acquired frequencies would be sufficient to establish a viable fourth nationwide carrier.

"On its own, we don't think this small amount [of] 800MHz spectrum is enough to make SpaceX a credible fourth player, even if deployed terrestrially in a hybrid network architecture," McHugh wrote.

He also raised doubts about whether small ground-based transmitters could replace the coverage and capacity provided by conventional cellular infrastructure.

"we are still not sure that SpaceX wants to go down the very long road of building out a terrestrial network on its own—moreover, this is likely to be a very challenging endeavor without an MVNO/roaming deal—as they will need to build a lot of coverage over many years to create something with mass market appeal, in our view. Doing this with small cells alone seems an impossible ask," McHugh wrote.

SpaceX analysts offered a more favorable assessment of the acquisition's strategic significance. Evercore ISI said the deal gave the company a clearer path toward developing its own network, while JPMorgan viewed the longer-term opportunity more positively.

"now has the outline of a real network" was Evercore ISI's assessment of SpaceX's position following the acquisition.

JPMorgan also evaluated the transaction as strengthening the company's longer-term prospects for mobile service.

"more credible," JPMorgan wrote in its assessment of Starlink Mobile's long-term opportunity.

The analysts nevertheless distinguished the long-term potential from the immediate competitive threat facing established carriers.

"That said, we continue to see limited near-term risk to U.S. wireless incumbents given the time, infrastructure and capital required to build a competitive terrestrial network," analysts added in a Friday note.

AT&T CEO John Stankey has previously described satellite connectivity as useful in areas where conventional wireless infrastructure is less effective. Speaking to Yahoo Finance at the Goldman Sachs Communacopia conference in September, he identified aviation, rural coverage and certain Internet of Things applications as potential opportunities.

"I think they're going to find places where they clearly have a good solution," Stankey told Yahoo Finance.

He pointed to aircraft connectivity and remote areas as examples of situations where satellite services can provide value.

"In airlines and flights today, they have a fantastic broadband solution. In rural parts or territories, it's a very efficient way to get good bandwidth to people. I think we see that there's going to be some IoT-type applications, like connecting vehicles that are largely outdoors and maybe have line of sight to the sky, that they're going to have an opportunity to go in and do some things there that maybe we haven't done as effectively," Stankey said.

Stankey also said traditional carriers could benefit by directing customers toward satellite operators when those services better meet specific connectivity needs.

"there's also going to be the complementary dynamic of us being able to solve that other 2% of the use cases I talked about and bring our customers to those satellite operators, whether it be Amazon or SpaceX. They'll be the beneficiary of us aggregating that traffic and bringing it into the wholesale market to be able to be used," Stankey said.

T-Mobile currently partners with SpaceX on its T-Satellite service, even as the companies' broader commercial interests may increasingly overlap. PCMag also reported that T-Mobile had formed a joint venture with AT&T and Verizon to support satellite-to-phone services. SpaceX's spectrum acquisition remains part of a broader effort to expand its presence in the U.S. mobile market, with regulatory oversight and infrastructure investment still central to its execution.
