SpaceX IPO vs. Rocket Lab: Which Space Economy Stock Is the Better Buy?
The piece compares SpaceX's huge IPO valuation with Rocket Lab's smaller but growing space business. It argues Rocket Lab may offer more upside, while SpaceX remains the higher-quality company.

The article frames SpaceX as the dominant space company but too richly valued for easy gains, while Rocket Lab is presented as a smaller, more volatile bet with more room to grow. The core question is whether investors want quality or risk-reward.
It is like choosing between a giant, famous store that already costs a fortune and a smaller store that is still growing fast. The giant may be safer, but the smaller one could grow a lot more if it keeps doing well.
Analysis
SpaceX: dominant, but priced for perfection
The article says SpaceX is the leading company in the modern space economy. It points to the company’s control of commercial launch services, the growth of Starlink, and continued work on Starship, which is meant for missions ranging from defense to deep space exploration.
The issue is not business strength. It is valuation. The story says SpaceX priced its IPO at $135 per share, implying a valuation of about $1.77 trillion. That size is compared with Saudi Arabia’s GDP to show how much growth is already embedded in the stock. In the article’s framing, a future doubling would require SpaceX to be worth more than $3.5 trillion, which sets a very high hurdle.
Rocket Lab: smaller, broader, and still growing
Rocket Lab is described as more than a launch company. The article notes that it also builds satellites, spacecraft components, solar arrays, flight software, and other space infrastructure. Its customers include commercial operators, NASA, and the U.S. Department of Defense.
The article backs up the growth case with operating results: 2025 revenue of about $602 million, up 38% year over year, a backlog above $2 billion, and first-quarter 2026 revenue of $200 million that exceeded guidance for revenue, gross margin, and adjusted EBITDA. It also highlights 21 launches in 2025 with a 100% mission success rate and an $816 million contract from the U.S. Space Development Agency.
The key catalyst
The biggest upside driver is Neutron, Rocket Lab’s larger partially reusable rocket, which is scheduled for a first launch in late 2026. If it works, the article says Rocket Lab could compete for larger launch contracts now dominated by SpaceX. But the company is still unprofitable and has already faced delays, so the risk remains real.
The article’s bottom line is straightforward: SpaceX is the stronger company, but Rocket Lab may be the better risk-reward bet if execution continues.
Key points
- SpaceX is described as the most important company in the modern space economy, but its valuation is already extremely high.
- The article says SpaceX’s IPO valued it at roughly $1.77 trillion, which limits easy upside from here.
- Rocket Lab is smaller, but it is expanding beyond launch into satellites, hardware, software, and other space infrastructure.
- Rocket Lab reported about $602 million in 2025 revenue, a backlog above $2 billion, and record first-quarter 2026 results.
- The main catalyst is Neutron, which could help Rocket Lab compete for larger launch contracts if development stays on track.
If Rocket Lab keeps hitting its targets, the company could use its growing revenue, backlog, and launch record to win bigger contracts. A successful Neutron launch could also help it challenge SpaceX for larger space jobs and expand its role across the space economy.
Rocket Lab still loses money, so any slowdown in execution could hit the stock hard. If Neutron slips again or fails to reach its goals, the company may struggle to justify the growth case the article builds around it.
