Starlink Mobile Carrier Plan Rattles AT&T, Verizon

The Starlink mobile carrier plan just turned into the biggest shake-up in US wireless in years. On Thursday night SpaceX said it will buy radio spectrum so Starlink can become a "major mobile carrier in the U.S.," and by Friday morning the big three phone companies were bleeding value.

Here's the short version: the Starlink mobile carrier idea means your phone could one day connect straight to satellites, even indoors. Wall Street reacted like that future is already here. Analysts say it isn't, but the market doesn't care about nuance when Elon Musk makes a move.

What SpaceX actually announced

According to CBS News, SpaceX agreed to buy licenses for radio airwaves from investment firm Grain Management, a deal laid out in a filing with the Federal Communications Commission. The spectrum would let its Starlink Mobile satellite business provide cellular service inside buildings, something satellite signals struggle with because walls and roofs weaken them.

"This is the last critical piece of the spectrum puzzle needed for SpaceX to provide complete phone coverage in America," Musk wrote in a social media post on Thursday. The purchase still needs FCC approval. SpaceX also said the FCC has approved Starlink Mobile's application to launch 15,000 satellites that will beam signals in the 2 gigahertz band directly to mobile phones.

The company said that once it gets final approval, Starlink Mobile will combine its satellite-to-mobile constellation with "an advanced terrestrial deployment that can seamlessly connect devices everywhere." Translation: satellites in space plus some kind of ground network, so the signal reaches you in your apartment, not just on a hiking trail.

Carrier stocks got hammered

The market reaction was brutal. According to NBC News, AT&T and Verizon both dropped about 10% on Friday morning while T-Mobile US plunged 14%, wiping out more than $50 billion in market value before lunch. Charter and Comcast, which sell wireless service on Verizon's network, fell too.

CBS reported T-Mobile slid $18.58, or 11%, to $152.72 in morning trading, while AT&T slipped $1.83, or 7.4%, to $22.76. SpaceX shares, meanwhile, gained $2.61, or 1.6%, to $163.18. Starlink has more than 12 million paying subscribers and is the only profitable part of SpaceX's business, according to its latest earnings report.

The carriers say: not so fast

The phone companies are downplaying the threat. "Acquisition of spectrum alone does not provide the network or infrastructure to offer true nationwide coverage or to compete with mobile providers," Verizon said in a statement to NBC News. T-Mobile's John Saw wrote that "you cannot acquire a nationwide, high-performing wireless network overnight."

Analysts mostly agree on the timeline. UBS analyst John Hodulik said the airwaves are compatible with existing handsets and he sees no obstacles to approval, but that it will take time for SpaceX to scale. JPMorgan analysts wrote that, absent a deal with an existing carrier, SpaceX would likely need to build a terrestrial network using macro towers to match traditional service.

Why this matters if you're on a phone plan

For anyone paying a big monthly bill, a fourth serious player is the best-case scenario. More competition has historically meant cheaper plans and better perks, and a satellite-first carrier could finally fix dead zones in rural areas, on highways and at festivals. FCC chairman Brendan Carr already sounded supportive, telling CNBC on Friday that it is "going to be really good news for the American consumer."

There's also a politics angle. Musk is a close ally of President Donald Trump, and NBC notes that favorable regulatory decisions are crucial to SpaceX's lofty valuation. The three big carriers have a complicated relationship with Starlink too: T-Mobile partnered with SpaceX in 2022 but has recently dropped the company's name from parts of its website.

What to watch next

Don't cancel your plan yet. The deal needs FCC sign-off, and building the ground side of the network takes years, not weeks. But the direction is clear: the line between space company and phone company is vanishing. For more on how big tech reshapes your daily life, check our business coverage and our tech coverage.
