Starlink vs AST SpaceMobile

Two fundamentally different approaches to satellite connectivity: Starlink delivers high-speed broadband through dedicated dish terminals, while AST SpaceMobile connects directly to unmodified smartphones from orbit. They target different markets but both aim to close the global connectivity gap.

Technology: Dish-Based Broadband vs Direct-to-Phone

Starlink operates the largest satellite constellation in history, with 11,117 working satellites as of October 11, 2026, providing broadband internet through a flat-panel phased-array dish (the Starlink terminal). Customers typically pay a one-time cost for the Starlink Kit plus a monthly subscription that varies by market and speed. SpaceX reports a median of 225 Mbps download at peak hours for residential users and median latency of about 25 ms (as of March 31, 2026), which SpaceX describes as fiber-like download speeds. Starlink has expanded beyond residential service into maritime, aviation, and enterprise markets, and SpaceX runs about 650 dedicated satellite-to-mobile satellites (Starlink Mobile) with about 30 carrier partners, including T-Mobile in the U.S., offering messaging, data and app-based voice services (as of March 31, 2026).

AST SpaceMobile takes a fundamentally different approach: each BlueBird carries a very large phased array, about 693 square feet (64 square meters) on the Block 1 satellites and up to about 2,400 square feet on Block 2, powerful enough to communicate directly with standard, unmodified cellular phones. No new equipment is needed on the user's side: the service is designed for standard, unmodified phones. AST demonstrated voice calls and 4G LTE data on the BlueWalker 3 test satellite in 2023, and 12 BlueBirds have reached orbit: five Block 1 satellites in September 2024 and seven larger Block 2 satellites between December 2025 and August 2026 (our launch records). A 13th, BlueBird 7, was lost when New Glenn left it in too low an orbit in April 2026. The trade-off is scale: AST estimates an average capital cost (direct materials and launch) of about $21 million to $23 million per Block 2 satellite and plans about 90 satellites for continuous service in all its targeted markets, against more than 11,000 working Starlink satellites (Oct 2026).

Market Strategy & Revenue Model

Starlink is SpaceX's subscription broadband business: SpaceX's Connectivity segment, primarily Starlink, generated $11.39 billion in revenue in 2025, Starlink had 12.0 million subscribers at June 30, 2026, and SpaceX says it serves customers in 167 countries, territories and other markets. The business is mostly direct to consumer (consumer subscribers were over 60% of Connectivity revenue in 2025), alongside enterprise, government and carrier revenue. Starlink also serves government customers: SpaceX reports significant business relationships with U.S. defense and government agencies, builds Starshield, a secure network for U.S. government and national security use, and says its satellites support connectivity during disasters and provide communications access in conflict zones.

AST SpaceMobile's approach is B2B: the company partners with mobile network operators (MNOs) who pay for satellite-extended coverage using their existing licensed spectrum. In the U.S., AST has agreements with AT&T, Verizon and FirstNet, and it has over 60 MNO partners worldwide, including Vodafone, Rakuten and Orange, which AST says collectively cover over 3 billion subscribers (August 2026). AST plans to earn service revenue through wholesale and revenue-sharing agreements with these operators; its revenue so far comes mainly from gateway equipment sales to operators and U.S. government work. This avoids direct consumer acquisition costs but ties consumer market access to MNO partners. AST had $70.9 million of revenue in 2025 and is working toward a beta service in 2026 before commercial SpaceMobile Service.

Public Listings

SpaceX went public on Nasdaq (SPCX) in June 2026, selling 638.9 million shares at $135.00 each, for net proceeds of $85.7 billion. AST SpaceMobile trades on Nasdaq as ASTS. Market values, where our company profiles have them, are in the table above, dated in the note under it. AST reported $46.3 million of revenue in the first half of 2026 and says it is fully funded to build and launch about 90 BlueBirds; the FCC has authorized up to 248. Its next stated milestone is a beta service with select operator partners in 2026, ahead of commercial SpaceMobile Service, and building and deploying these very large satellites at scale is technically complex.
