Space Sector Stocks Shift Amid Defense Budget Increases
Investment analysts identify Lockheed Martin, Rocket Lab, and AST SpaceMobile as key space-sector stocks amid rising defense spending and the Golden Dome initiative.
Investment analysis for October 2026 identifies three space-sector stocks with distinct risk profiles driven by rising defense budgets and the Golden Dome missile defense initiative. Lockheed Martin is positioned as the strongest option, supported by a record $230.42 billion backlog and a $35 billion THAAD missile defense contract. However, the company faces challenges from declining F-35 deliveries and a Vulcan launch failure.
Rocket Lab is categorized as the fastest-growing pure play in the sector. The company reported a 62% year-over-year revenue increase in the second quarter of 2026 and a record $2.36 billion backlog. Its future growth depends on the successful launch of the Neutron reusable rocket, though CEO Peter Beck noted that the window for an end-of-year launch is narrowing.
AST SpaceMobile represents the highest potential upside through its BlueBird satellites but remains a speculative investment. The company missed revenue estimates in both the first and second quarters of 2026 and reported significant losses following a launch incident.
