3 space stocks gain as SpaceX dominance fuels second-source demand

SpaceX's expanding share of the launch market is creating a counterintuitive opportunity for rival operators as governments and telecom operators seek redundancy.

Three space stocks rose June 19 as investors bet that SpaceX's market dominance will drive demand for alternative launch and satellite providers.

"SpaceX may dominate the space economy, but that dominance could make second-source providers more valuable as governments, telecom operators, and defense agencies look for redundancy, resilience, and strategic alternatives," according to a June 28 analysis from Motley Fool.

AST SpaceMobile led the group, climbing 9.08%, followed by Rocket Lab at 4.67% and Redwire at 0.32%. SpaceX's own shares edged up 0.15%. The moves came as AST SpaceMobile advanced toward its next satellite launch, targeting BlueBirds 11, 12, and 13 for the first half of August.

The thesis hinges on a structural shift in the space economy. As SpaceX captures an expanding share of the launch market, customers from defense agencies to telecom operators may increasingly contract with second-source providers to ensure supply chain resilience. That dynamic could redirect capital toward companies offering complementary launch and satellite infrastructure capabilities.

AST SpaceMobile leads on satellite deployment progress

AST SpaceMobile has already launched BlueBirds 8, 9, and 10, which the company says are operating in orbit. The next three satellites, expected to launch in August, will carry 2,400-square-foot antennas and are projected to nearly double the network's peak download speed from 98.9 megabits per second. Management said new satellites could support 4G or 5G service with mobile network partners about 45 days after launch, with a goal of cutting that setup period to roughly two weeks over time.

The company has contracted launch capacity across three providers — SpaceX's Falcon 9, which can carry three BlueBird satellites; Blue Origin's New Glenn, which can carry up to eight; and United Launch Alliance's Vulcan, which can carry up to five — supporting its 2026 target of roughly 45 satellites in orbit. The multi-provider strategy itself reflects the second-source principle AST SpaceMobile is betting will drive broader industry demand.

The financial trajectory reflects the scale of the ambition. AST SpaceMobile reported first-quarter revenue of $14.7 million but guided for $150 million to $200 million in full-year 2026 revenue, with management projecting 2027 revenue could approach $1 billion as cellular broadband service launches in major markets. The company held $3.5 billion in cash against $3.02 billion of total debt at the end of the first quarter, providing flexibility to fund its commercial strategy.

Rocket Lab and Redwire offer complementary exposure

Rocket Lab, which operates the Electron and Neutron launch vehicles, stands to benefit as government and commercial customers seek alternatives to SpaceX for small-to-medium payload launches. Redwire, a space infrastructure and manufacturing company, provides hardware for satellite platforms and in-space servicing — areas where defense and intelligence agencies increasingly want diversified suppliers.

The three stocks together represent different layers of the second-source thesis: launch services (Rocket Lab), satellite manufacturing and infrastructure (Redwire), and direct-to-device satellite connectivity (AST SpaceMobile). Each addresses a segment where single-provider dependency carries strategic risk for customers, from national security payloads to commercial broadband networks.
