The article compares two space infrastructure companies: AST SpaceMobile, which is building a space-based cellular network for direct smartphone connectivity, and Firefly Aerospace, which provides launch vehicles and lunar landers. While AST SpaceMobile has higher growth potential with major carrier partnerships, it trades at a significantly higher valuation (269x forward P/E) with untested technology and substantial losses. Firefly Aerospace, valued more conservatively at 21.9x forward P/E, has demonstrated success with its lunar landing and government contracts. The author recommends Firefly as the better buy in 2026 due to more reasonable valuation metrics.
