The SpaceX IPO Put a Spotlight on Starlink -- and on the One Public Company Building a Rival Direct-to-Phone Network
Editorial Commentary — Commercial Space Series SpaceX ' s public listing cast Starlink Mobile as a future wireless challenger. AST SpaceMobile (NASDAQ: ASTS ) is the most prominent publicly traded company pursuing the same direct-to-device satellite-broadband market. Key Takeaways The SpaceX IPO prospectus framed Starlink Mobile as a direct-to-smartphone service intended to compete with terrestrial mobile networks — spotlighting a market that public investors cannot access through SpaceX alone. AST SpaceMobile (NASDAQ: ASTS ) is the most prominent listed company building a direct-to-device satellite-broadband network , connecting ordinary, unmodified smartphones from space. AST has reported securing over US$1.2 billion in aggregate contracted revenue commitments from partners, and is targeting 45 to 60 satellites in orbit by the end of 2026. Other listed satellite-connectivity names include Globalstar (NASDAQ: GSAT ) and Viasat (NASDAQ: VSAT ) — each distinct, and neither a proxy for the other. The IPO That Made Satellite-to-Phone a Headline , /PRNewswire/ -- Equity Insider Market Commentary, When Space Exploration Technologies Corp. (SpaceX) filed to go public on the Nasdaq under the proposed ticker SPCX, the prospectus did more than reveal the financials of the world's most valuable private company. It laid out, in detail, how SpaceX intends to turn its Starlink constellation into a wireless competitor — casting Starlink Mobile as a direct-to-smartphone service designed to perform "on par with terrestrial mobile networks," with next-generation satellites slated to expand the offering beyond messaging toward full broadband and IoT connectivity.

That framing turned a once-niche idea — connecting an ordinary phone directly to a satellite, with no special hardware — into a front-page investment theme. But there is a catch for public investors: SpaceX's satellite-to-phone business is bundled inside an enormous company spanning launch, Starlink broadband, and an artificial-intelligence unit. For those seeking a focused, public-market way to play the direct-to-device race specifically, the most prominent name is not SpaceX at all. It is AST SpaceMobile. AST SpaceMobile: The Public Pure-Play on Phones-From-Space AST SpaceMobile (Nasdaq: ASTS ), based in Midland, Texas, is building what it calls a space-based cellular broadband network designed to connect everyday, unmodified smartphones directly to its satellites — aiming to eliminate mobile "dead zones" worldwide. Where Starlink began as a fixed-broadband service using dedicated terminals, AST's entire thesis is the direct-to-device market that SpaceX's IPO filing has now thrust into the spotlight. That makes the two natural — if vastly differently sized — competitors in the same emerging category. The company has been building both its constellation and its commercial foundation. AST reported full-year 2025 revenue of about US$70.9 million, driven by mobile-network-operator partners and the U.S. government, and said it had secured over US$1.2 billion in aggregate contracted revenue commitments from partners — a figure that speaks to the scale of carrier interest. It has also reported completing the in-orbit unfolding of BlueBird 6, which it described as the largest commercial communications array ever deployed in low Earth orbit, and has laid out a launch cadence intended to reach 45 to 60 satellites in orbit by the end of 2026. The risk profile is equally clear, and worth stating plainly: AST is a capital-intensive, still-largely-pre-revenue business whose value depends on executing a demanding manufacturing-and-launch campaign on schedule. A successful deployment validates the model; a stumble in cadence or array deployment would do the opposite. This is a build-it-first business, and the build is far from finished. How AST and SpaceX Actually Differ It would be a mistake to treat AST as a miniature Starlink. The two take different technical and commercial approaches: AST partners with terrestrial mobile-network operators to extend their existing networks from space, positioning itself as a complement that carriers integrate, rather than a stand-alone consumer ISP. SpaceX, by contrast, has the advantage of owning its own launch vehicles — it flies Starlink satellites on its own Falcon 9 and Starship rockets — plus enormous scale and a head start in subscribers. AST's counter is focus and carrier alignment: it is building specifically for the direct-to-device use case in partnership with the incumbents whose customers it would serve. Which model wins, or whether both coexist, is exactly the open question the SpaceX IPO has made unavoidable. Tracking how this sector is being repriced in real time?

The Wider Satellite-Connectivity Field Beyond AST, a couple of listed satellite-connectivity companies help frame the landscape — each with a distinct model and risk profile, and neither a proxy for the other. Globalstar (Nasdaq: GSAT ) provides mobile satellite services and wholesale capacity, reporting first-quarter 2026 revenue of about US$70.1 million, up 17% year-over-year, and has been a long-running infrastructure partner in the satellite-to-phone space. Viasat (Nasdaq: VSAT ) anchors the broadband-and-connectivity end as a diversified satellite-communications operator serving aviation, government, and consumer markets. Together with AST, these names show that "satellite connectivity" spans several business models — wholesale capacity and diversified broadband — all being re-rated as the direct-to-device opportunity SpaceX highlighted draws fresh capital and attention. Each, however, will live or die on its own constellation, balance sheet, and execution. A Note on the Broader Space Trade One smaller name investors scanning the sector may note is Starfighters Space, Inc. (NYSE American: FJET) , mentioned here for context only and not as a recommendation. The company has publicly described operating what it calls the world's only commercial fleet of flight-ready Mach 2+ supersonic F-104 aircraft from NASA's Kennedy Space Center, and in May 2026 it announced a US$17.5 million strategic equity investment led by institutional investors, with proceeds earmarked to support operational expansion and continued advancement of its STARLAUNCH platform. These are the company's own announced figures; readers should verify them in its filings. The Bottom Line The SpaceX IPO did more than reveal Starlink's economics — it confirmed that connecting ordinary phones directly to satellites is a market the most sophisticated player in space intends to pursue aggressively. For public investors, that validation lands not on SpaceX's sprawling franchise but on the focused names building in the same direction. AST SpaceMobile is the most prominent of them, with carrier commitments and an ambitious deployment plan — and the considerable execution risk that comes with building a constellation from scratch. The question the IPO sharpened is no longer whether satellite-to-phone is real, but who builds the winning network. The answer will come from orbit, on a schedule, over the next several years.
