AST SpaceMobile vs. Rocket Lab: 1 Number Separates These Space Stocks

The article compares AST SpaceMobile with Rocket Lab and argues that revenue is the clearest divide between the two space stocks. Rocket Lab is described as the more mature business, generating about $200 million in quarterly revenue and growing more than 60% year over year, supported by a backlog above $2 billion. AST SpaceMobile, by contrast, is still early in commercialization, with roughly $15 million in its latest quarterly revenue and 2026 guidance of only $150 million to $200 million for the full year. The piece frames Rocket Lab as the lower-risk, revenue-producing operator today, while AST offers higher long-term upside if its satellite-to-phone service scales. The market implication is a classic speculative-vs-established growth comparison: AST’s recent 14.79% drop underscores investor caution around execution risk, while Rocket Lab is positioned as the more proven revenue story.
