SpaceX Picks Qualcomm Chips for Starlink Mobile's 5G Ground Network

Qualcomm will supply the silicon for SpaceX's ground-based 5G network, a deal announced Wednesday that puts tens of thousands of base station sites on a rollout schedule starting in 2027. Neither company disclosed financial terms, and SpaceX shares still slipped about 3% on the day, trading near $136 — almost a third below their record close of $201.80.

Qualcomm said SpaceX chose its Dragonwing cellular infrastructure platforms for Starlink Mobile's nationwide 5G network. The agreement spans multiple years and covers the ground side of a plan that would make SpaceX a full US wireless carrier.

What exactly did Qualcomm win?

The deal involves two platforms. The QRU100 will power the radio units, while the QDU100 handles signal processing. Qualcomm also supplies the Layer 1 software that runs the network's physical radio layer. The radios will use 64 transmit and 64 receive paths, an antenna configuration built to carry more traffic on the same airwaves.

SpaceX remains the architect. The company is designing and rolling out the network itself, with Qualcomm's chips inside.

"We're excited to collaborate with Qualcomm Technologies and leverage their industry expertise and platform to accelerate our timeline to develop our base station end-to-end architecture," said Michael Nicolls, Starlink's senior vice president, in Qualcomm's release.

Where did the spectrum come from?

The chip deal follows more than a year of spectrum buying. SpaceX agreed to pay roughly $19.6 billion, in shares and payments on EchoStar's debt, for EchoStar licenses covering up to 65 MHz of spectrum. That transaction is expected to close near the end of November 2027.

On October 8, SpaceX also agreed to buy a nationwide portfolio of 800 MHz airwaves, which it expects to own by the middle of next year.

President Gwynne Shotwell, speaking on SpaceX's October 20 third-quarter call, said the S-band airwaves should handle most of the traffic, while the 800 MHz spectrum is there "to basically penetrate buildings." She added that SpaceX's short-term priority is flying its Mobile V2 satellites through 2027 and integrating its spectrum purchases, with service starting in early 2028.

How does the carrier plan fit SpaceX's finances?

Starlink Mobile's revenue currently sits inside SpaceX's enterprise and government sales line, which climbed 91% year over year to $2.1 billion in the third quarter. The quarterly filing credits most of that growth to more aircraft activations, and SpaceX does not break out the mobile portion.

The connectivity segment that houses it already drives the business. Connectivity revenue rose 69% year over year to $5.2 billion in the third quarter, faster than its 66% growth in the second quarter. Segment operating income nearly doubled, up 99% to $2.4 billion. Operating margin jumped to roughly 45%, from about 38% in both the year-ago quarter and the second quarter. Connectivity contributed about 85% of SpaceX's total operating income of $2.8 billion. The company's AI business, which it calls super intelligence, earned $431 million in operating income.

CEO Elon Musk told investors he sees "a clear path to several hundred billion dollars a year in connectivity revenue." Connectivity runs at around $21 billion a year today, so that forecast implies growing the segment many times over.

Does the network change the investment picture?

The cell sites add to an already large bill. Management expects fourth-quarter capital spending alone to land at $35 billion to $40 billion as more AI computing capacity comes online. SpaceX has not said what the ground network itself will cost.

At a valuation of roughly $1.85 trillion, SpaceX trades on expectations of years of fast growth. Management forecasts $33 billion to $37 billion in revenue for the first quarter of 2027; if the midpoint held for a full year, the stock would trade at around 13 times sales. A phone network that may bring in little revenue before 2028 arguably adds nothing to the next couple of years of it.

The Qualcomm contract makes Starlink Mobile's carrier plan more concrete: SpaceX now has spectrum deals, a base station supplier and a 2027 start date. What it does not have yet is revenue from any of it. Service is slated to begin in early 2028, once the Mobile V2 satellites are flying and the spectrum purchases are integrated.
