SpaceX has spent years proving it can put hardware in orbit. Its next challenge sits much closer to the ground — in spectrum rights, roaming contracts and the balance sheet.
The company’s third-quarter 2026 results show why the mobile push matters. SpaceX posted revenue of $14.6 billion and a net profit of $4.4 billion, swinging back into the black after a loss in the prior-year period. Starlink, the engine behind that turnaround, counted roughly 13.6 million users at the end of the quarter, with the connectivity business generating $5.2 billion in quarterly revenue.
Yet the path into terrestrial mobile is anything but cleared. According to a Washington Post report published yesterday, SpaceX is in talks with EchoStar over a purchase of Boost Mobile or access to its network. Neither company has confirmed a deal, and no price has surfaced. EchoStar reported about 7.38 million mobile customers at the end of the second quarter of 2026 — a base SpaceX could tap rather than building a subscriber roster from scratch.
Spectrum Is Granted, but Not Entirely
Regulatory progress has been partial. On October 6, the Federal Communications Commission approved SpaceX’s application for Starlink Mobile Gen2 with up to 15,000 satellites. Some requests were granted; others were set aside, including a proposed use of a frequency band in the United States. The satellite count alone therefore understates the constraints — the permitted frequency uses define the real regulatory room to maneuver.
Two days later, SpaceX agreed to buy a nationwide portfolio of 800 MHz spectrum licenses from Grain Management. That transaction is expected to close in the first half of 2027, subject to regulatory and customary conditions. Approved satellites and agreed spectrum purchases represent different stages of progress and should not be treated as equivalent.
The Boost Question: Customers Without a Network
The industrial logic behind the EchoStar talks is easy to see. Pairing Starlink with terrestrial mobile could turn a collection of separate offerings into a broader service promise — not just more subscribers, but a more widely usable product.
The snag is infrastructure. Boost runs on leased networks from AT&T and T-Mobile, and transferring those contracts could require their consent. The Washington Post reported that the major carriers had previously denied SpaceX network access. Acquiring Boost would not automatically deliver conflict-free access to the infrastructure it needs. BNP Paribas analyst Sam McHugh sees a Boost purchase as possible legal grounds to challenge anticompetitive blocking — an interesting angle, though hardly a guarantee of a smooth market entry. A stronger negotiating position and a usable network agreement are two different things.
Should investors sell immediately? Or is it worth buying SpaceX?
SpaceX plans direct satellite-to-mobile service in the US from early 2028, targeting full 5G quality in the first half of 2028. Between today’s talks and that launch lies a substantial execution phase. The timeline is a goal, not a competitive advantage already banked.
A Data-Privacy Thread Worth Watching
Alongside the regulatory and commercial fronts, a Reuters report on October 27 added another item to the investor checklist. Research by TrendAI found that Israeli ad-tech firm Discover-Tech was a leading bidder for advertising shown to Starlink users in more than 100 countries, according to people familiar with the investigation. The concern centers on whether ad data could be used for location tracking or surveillance of users. That is not a finding that such surveillance occurred, nor evidence of wrongdoing by SpaceX. Distinguishing a potential data risk from proven misuse is essential when assessing the network buildout.
Capital Demands Force Priorities
The financial backdrop is demanding. SpaceX expects capital expenditures of $35–40 billion in the fourth quarter of 2026. On October 24 it signed a binding commitment for a conditional financing lease with a vehicle managed by Apollo Global Management, with expected repayments totaling roughly $40 billion plus interest and certain ongoing costs, subject to closing conditions. That facility covers GPU equipment and is not a designated budget for Boost — a distinction worth keeping in mind, since both projects must justify their own economics.
A separate master financing lease agreement with another Apollo-managed entity, announced about a week ago, is set to begin as equipment is delivered in the first half of 2027.
The picture that emerges is of a company whose profit rebound strengthens its starting position while its spectrum deals and lease obligations shape future execution. Boost could open valuable access to the mobile market, but the strategic idea still outshines its secured implementation. As long as network rights, purchase price and additional financing remain open, caution toward a hasty re-rating is warranted. What matters is not ownership of Boost alone, but a workable relationship between access, cost and return.
