Is Elon Musk Coming for Telecom Stocks?

For most of its existence, Starlink was viewed as a niche product. A satellite dish for people who lived too far from a cell tower or a cable line. That story changed dramatically over the past year. Starlink has quietly evolved from a rural broadband service into something that increasingly looks like a direct competitor to the largest wireless carriers in the United States.

The shift accelerated in a single week of June 2026. SpaceX completed the largest IPO in history, raising approximately $75 billion at a valuation near $1.75 trillion. Days later, SpaceX President Gwynne Shotwell told investors during the roadshow that the company plans to challenge AT&T, Verizon, and T-Mobile directly. For an industry that has not faced a serious new entrant in decades, that statement landed like a warning shot.

From Satellite Dishes to Smartphones

The technology making this possible is called direct-to-device connectivity, or D2D. In simple terms, it allows an ordinary smartphone to connect straight to a satellite in orbit, the same way it normally connects to a cell tower, without any extra hardware.

Starlink's relationship with T-Mobile, first announced in 2022, was the moment that turned this from a concept into a real product. T-Mobile contributed a slice of its wireless spectrum, and Starlink built the satellite layer on top of it. The result is a service called T-Satellite, which fills coverage gaps for T-Mobile customers in places where there is no cell tower nearby. It works today, and it is already live.

But in that arrangement, T-Mobile still owns the customer. SpaceX is the supplier working in the background. What has investors and rival carriers paying close attention now is the possibility that SpaceX stops being a supplier and starts being the carrier itself, selling its own mobile plans, under its own brand, billing customers directly.

An Unprecedented Alliance Among Rivals

Perhaps the clearest sign that the telecom industry is taking this seriously came in mid-May 2026. AT&T, T-Mobile, and Verizon, three companies that spend billions of dollars every year fighting each other for customers, announced they had agreed in principle to form a joint venture. The goal: pool their spectrum resources to build out their own satellite-based direct-to-device coverage across the country.

This was the first time in the history of the U.S. wireless industry that the three largest carriers have aligned on a joint infrastructure project of this kind. The timing was not a coincidence. It came directly in response to Starlink's expanding satellite ambitions, particularly the threat to rural and underserved coverage zones where satellite links can outcompete a traditional cell tower entirely.

All three carriers have so far declined to offer SpaceX a wholesale network deal of the kind that would let it operate as a guest on their networks. Both AT&T's and T-Mobile's CEOs said as much explicitly on their first-quarter 2026 earnings calls. That refusal matters, because it pushes SpaceX toward building its own independent path into the mobile market rather than partnering its way in.

The Case for Starlink as a Real Threat

SpaceX has a structural advantage that is difficult for any competitor to copy. It builds its own satellites, launches them on its own rockets, and owns the entire supply chain end to end. Every new batch of satellites goes up at SpaceX's own cost, not at a price paid to an outside launch provider. That is a cost structure that no traditional telecom company, and no rival satellite operator, can currently match.

The scale of the buildout backs this up. As of mid-2026, Starlink has launched more than 650 satellites dedicated specifically to direct-to-cell coverage, part of a broader constellation of roughly 10,000 satellites in orbit. The company has also secured FCC approval to expand that constellation by another 7,500 satellites, which would push the total system past 15,000. According to SpaceX's own IPO disclosures, Starlink crossed 10.3 million subscribers across 160 countries by the end of the first quarter of 2026, more than double its subscriber count from just over a year earlier.

Financially, Starlink is no longer the experimental side project it once was. The connectivity business generated approximately $11.4 billion in revenue in 2025, up roughly 50% from the prior year, and posted a $1.19 billion operating profit in the first quarter of 2026 alone. Notably, connectivity is the only consistently profitable part of SpaceX's business today. The rocket and launch division actually lost money in the same quarter, and the company's AI unit posted a larger loss still.

At Mobile World Congress in March 2026, a senior SpaceX executive said Starlink Mobile had already surpassed 10 million subscribers and that the company expects to add roughly 52,000 new mobile users per day through the rest of the year, targeting 25 million active users by year end. Trademark filings for the name "Starlink Mobile" further support the idea that the company may be preparing to launch its own standalone wireless service rather than remaining a behind-the-scenes partner.

Why Replacing Telecom Networks Will Not Be Easy

Despite all that momentum, building a true nationwide wireless carrier is not simply a matter of putting more satellites in orbit. SpaceX still holds far less wireless spectrum than the major U.S. carriers do, and spectrum is the single most valuable and most tightly regulated resource in the entire industry. Buying additional spectrum, whether from existing carriers or in future government auctions, will be expensive and slow.

There is also the matter of towers. Satellite connectivity today works well for text messages and basic data in areas without coverage, but full voice calls and high-speed data at the level customers expect from a normal phone plan still require a far denser, more capable network than satellites alone can provide. Closing that gap is exactly why analysts describe SpaceX as still needing terrestrial infrastructure investment on a scale it has not yet committed to.

Competition is also building from another direction. AST SpaceMobile, a smaller satellite company, has struck partnerships with AT&T, Verizon, and Vodafone, giving it a broader carrier footprint in the U.S. than Starlink currently has through its T-Mobile-only arrangement. AST SpaceMobile's satellite fleet is far smaller and its capital base is thinner, but its multi-carrier strategy is a meaningfully different bet than SpaceX's path, and one that some of the same carriers racing to respond to Starlink are backing directly.

What SPCX Changes for Traders

SpaceX's stock market debut adds a new layer to this story that did not exist a few months ago. The company priced its shares at $135 and began trading on the Nasdaq under the ticker SPCX on June 12, 2026. Demand was strong enough that shares briefly traded above $225 within days, a level that pushed SpaceX's market value past both Amazon and Microsoft before the stock pulled back. By late June, shares were trading closer to $153, still comfortably above the IPO price.

Public investors are now buying into three different businesses inside one ticker: the rocket and launch operation, the Starlink connectivity business, and an artificial intelligence unit built around xAI, which SpaceX folded into the company in an all-stock deal earlier this year. Of those three, connectivity is the one with the clearest, most immediate, and most quantifiable threat to an existing public market sector: telecom.

That distinction matters for how traders think about the story. SpaceX going public does not by itself change Starlink's competitive position against Verizon or AT&T. But it does mean Starlink's subscriber growth, its connectivity profit margins, and any future announcement about a standalone mobile plan will now show up in quarterly filings that the entire market can read, track, and react to in real time, the same way it already does with the major carriers.

What Traders Should Watch

This story connects several major market themes at once: Elon Musk's broader business empire, satellite technology, AI infrastructure spending, and the future of how mobile networks compete. For traders following the telecom and space sectors, these are the developments that matter most going forward:

Starlink Mobile subscriber growth and whether SpaceX hits its stated target of 25 million active users by the end of 2026.
Any formal launch of a standalone Starlink mobile plan that bills customers directly rather than operating through T-Mobile.
Progress on the AT&T, Verizon, and T-Mobile joint venture and how quickly the three carriers can build out their own satellite-based coverage in response.
Postpaid phone churn at the major carriers, which already ticked higher in the first quarter of 2026 amid rising competitive pressure.
Spectrum deals and FCC decisions involving SpaceX, since spectrum access remains the single largest obstacle to a full Starlink mobile buildout.
SPCX quarterly earnings for a clearer breakdown of Starlink's connectivity margins now that the segment reports separately as part of a public company.

Starlink wants to go BIG

Starlink has not replaced Verizon, AT&T, or T-Mobile, and it is not close to doing so today. Building a true nationwide wireless network still requires spectrum, towers, and regulatory approvals that take years to secure. But the fact that the three largest U.S. carriers chose to form an unprecedented joint venture rather than compete separately tells you how seriously the industry is treating the threat.

With SpaceX now a public company, the next phase of this story will be easier to track than ever before. Every quarterly report will show whether Starlink's connectivity business keeps growing at its current pace, and every new development on a standalone mobile plan will move both SPCX and the legacy telecom stocks that now have a real reason to pay attention.
