What this means for investors

AST SpaceMobile stock plunged as investors fear it could be lagging further behind SpaceX in its bid to deliver satellite broadband. After announcing plans to acquire a spectrum portfolio from digital infrastructure company Grain Management, SpaceX investors see more of its broad growth and expansion goals.

AST SpaceMobile has been investing heavily to deploy satellite constellations to connect directly to smartphones, eliminating the need for added ground gear or special devices.

With SpaceX’s purchase of low-band spectrum, it seeks to challenge telecommunications giants by providing mobile service through Starlink Mobile. SpaceX also gained FCC approval last month for a 15,000-satellite direct-to-cell network, further pressuring AST SpaceMobile’s long-term plans.

Investors are beginning to worry that AST SpaceMobile may not see the returns on the vast satellite investments it needs.
