AST SpaceMobile vs. Rocket Lab: 1 Number Separates Them
💡 Key Takeaway
Rocket Lab's $200M quarterly revenue dwarfs AST SpaceMobile's $15M, but AST's satellite-to-phone potential could flip the script if its network scales.
Revenue Gap Defines Two Space Stocks
AST SpaceMobile (ASTS) and Rocket Lab (RKLB) are two of the most talked-about space stocks, but they couldn't be more different in terms of business maturity. Rocket Lab generated roughly $200 million in revenue in a single quarter earlier this year, growing more than 60% year-over-year. In contrast, AST SpaceMobile guided to $150 million to $200 million for the entire year of 2026, and its most recent quarterly revenue was only about $15 million.
This means Rocket Lab books in three months what AST hopes to earn in 12 months. The comparison highlights where each company sits on the maturity curve. Rocket Lab is an operating business with two revenue engines—launch services and satellite manufacturing—plus a backlog of over $2 billion. AST is still transitioning from promise to product, only now switching on commercial service after years of building its network.
However, revenue measures where a company is today, not where it might be tomorrow. AST has locked in more than $1 billion of contracted commitments from wireless carriers and holds a large cash pile to fund its build-out. If satellite-to-phone service scales as partners expect, AST's revenue could eventually surpass Rocket Lab's by tapping a global consumer market.
Neither company is consistently profitable yet, so both belong in the speculative corner of a portfolio. The revenue gap is best read as a measure of risk and timing: Rocket Lab has proven it can sell what it makes, while AST asks investors to trust that sales are coming.
Why This Revenue Comparison Matters for Investors
The stark revenue difference between Rocket Lab and AST SpaceMobile directly impacts stock valuation and risk. Rocket Lab's $200 million quarterly revenue with 60% growth and $2 billion backlog provides tangible evidence of market demand and operational execution. This lowers the risk for investors, as the company has diversified revenue streams and a clear path to profitability.
AST SpaceMobile, on the other hand, is a high-risk, high-reward bet. Its $15 million quarterly revenue and reliance on future carrier commitments mean the stock price is driven by narrative and potential rather than current earnings. If AST's satellite-to-phone network successfully scales, it could disrupt the telecom industry and generate massive revenue. But if it faces delays or technical issues, the stock could suffer.
For investors, this comparison helps decide which space stock aligns with their risk tolerance. Rocket Lab offers a more established business with lower downside, while AST SpaceMobile presents a speculative opportunity with higher upside. The choice ultimately depends on whether you prefer a proven operator or a visionary bet on the future of connectivity.

Bobby Insight
Rocket Lab is the better buy for risk-averse investors, while AST SpaceMobile suits those seeking higher upside.
Rocket Lab's established revenue base and backlog provide a safety net, making it a more reliable investment in the near term. AST SpaceMobile's potential is enormous but unproven, so it's suitable only for speculative portfolios. Both have merit, but RKLB offers a clearer path to profitability.
