Better Vertically Integrated Space Stock: SpaceX or Rocket Lab?

SpaceX and Rocket Lab are the two purest public examples of vertically integrated space companies, controlling their own rockets, satellites, and services. SpaceX is the dominant leader with proven scale and integration, while Rocket Lab is earlier in executing the same playbook through recent acquisitions like Iridium. SpaceX is the safer choice for established dominance, but Rocket Lab offers higher growth potential at a cheaper valuation for risk-tolerant investors.
