SpaceX and Rocket Lab are the two dominant vertically integrated launch companies in the Western world. SpaceX leads on scale (~$1.4T valuation, 132 launches in 2025, Starlink), while Rocket Lab leads among publicly traded pure-play space stocks (~$12B market cap, NASDAQ: RKLB). This page compares every dimension: vehicles, financials, strategy, launch records, and space systems capabilities.

SpaceX launches approximately 8x more frequently than Rocket Lab by count. However, Rocket Lab is the only other Western company achieving consistent monthly launch cadence, and Electron flight rate has doubled in two years.
| Year | SpaceX | Rocket Lab | SpaceX/RKLB Ratio |
|---|---|---|---|
| 2021 | 31 | 6 | 5.2x |
| 2022 | 61 | 9 | 6.8x |
| 2023 | 96 | 10 | 9.6x |

Both companies extend well beyond launch, but in different directions. SpaceX built Starlink to generate revenue from its own rockets. Rocket Lab sells components and spacecraft to other companies, creating a space supply chain business.
Starlink: 7,000+ sats, 5M+ subscribers, $8B+ ARR. SpaceX is both the launch provider and the largest customer for its own rockets.
No constellation. Rocket Lab builds spacecraft (Photon) and components for other constellation operators. Revenue from others' constellations without constellation risk.
Dragon: crew and cargo to ISS/LEO. Used for NASA Commercial Crew and private missions (Polaris, Axiom). No third-party spacecraft sales.
Photon: configurable satellite bus for LEO, lunar, and interplanetary missions. Flew to the Moon (CAPSTONE for NASA). Available for third-party missions.
Builds components in-house for Falcon/Starship/Starlink. Does not sell components externally. Captive supply chain.
Sells solar panels, reaction wheels, star trackers, separation systems, and flight software to other spacecraft manufacturers. Non-captive revenue growing 40%+ YoY.
Operates 3 launch sites (KSC, Vandenberg, Boca Chica). Starlink ground station network worldwide.
Operates 2 launch sites (Mahia NZ, Wallops VA). Focus on rapid launch turnaround for Electron.
SpaceX is private at ~$1.4T (IPO filed April 2026, $2T+ target). Rocket Lab is the most liquid publicly traded proxy for the commercial launch thesis. This comparison is context, not investment advice.
SpaceX and Rocket Lab share the same DNA -- vertical integration, hardware iteration speed, and an ambition to be more than a launch company -- but they serve different segments of the market. SpaceX is pursuing planetary-scale infrastructure (Starlink, Starship, Mars) at a scale that dwarfs any competitor. Rocket Lab is building the premier public-market space company, offering investors exposure to launch, spacecraft, and space systems in a single ticker. The companies are less competitive than complementary: SpaceX defines the frontier, while Rocket Lab serves the medium-market customers, government missions, and component supply chain that SpaceX does not prioritize. Neutron is the key catalyst for Rocket Lab -- if successful, it positions RKLB as a credible second source for constellation deployment and national security launch, the two largest addressable markets in the industry.
