Private space companies are building the infrastructure that could make permanent human settlement beyond Earth a reality.
From reusable rockets to commercial space stations to lunar landers, these firms are solving the transportation and habitation challenges that governments have spent decades studying but never fully committed to funding.
The private space industry has matured rapidly. SpaceX now dominates global launch, Blue Origin has joined the orbital club, and the first standalone commercial space station could reach orbit within two years.
In February 2026, SpaceX announced a major strategic shift toward building a self-sustaining city on the Moon, complete with lunar manufacturing and electromagnetic mass drivers. That announcement underscores how fast the industry is moving, and how seriously private enterprise is taking permanent settlement.
These companies are privately held, so direct stock investment is not possible. For publicly traded space companies, visit the public space companies page. To support the broader effort, consider lobbying Congress for space development legislation such as the Space Settlement Prize Act, or volunteering with the companies listed below. Many are actively hiring.
Getting to space affordably and reliably is the foundation of everything else. Without low-cost launch, space stations are unaffordable, lunar missions are one-offs, and settlement is impossible. The companies below are building the rockets that make the rest of this page possible.
The International Space Station is expected to be deorbited around 2031. NASA is betting that private companies can build and operate replacements at lower cost, and has awarded over $500 million to help develop them. If these stations succeed, they will provide the first permanent commercial platforms for research, manufacturing, and tourism in orbit, a critical stepping stone toward larger habitats and eventual settlement beyond low Earth orbit.
A growing number of private companies are building landers, rovers, and transportation systems to deliver payloads to the Moon and beyond. NASA's Commercial Lunar Payload Services (CLPS) program has been a significant catalyst, contracting with private firms to deliver science instruments to the lunar surface. These companies are building the delivery infrastructure that any future settlement will depend on.
The companies listed above are solving the hardest engineering problems in space: affordable launch, orbital habitation, lunar delivery, and in-space logistics. But engineering alone has never produced a permanent settlement.
Every lasting settlement in human history has rested on an economic foundation. Settlers needed to own what they built and the land they built on. Property ownership created collateral, attracted follow-on investment, and gave ordinary people a financial reason to relocate permanently.
Today, SpaceX has demonstrated that a single company can fund pioneering transportation through cross-subsidy and sheer will. That answers a question many doubted could be answered. But it answers only the first question. A self-sustaining community of thousands requires a local economy: mortgages, land sales, capital for businesses that don't yet exist. That requires property rights. And no company, however well-funded, can grant them to itself.
The 1967 Outer Space Treaty prohibits nations from claiming sovereignty over celestial bodies, but it does not address private property rights. When SpaceX announces plans for a lunar city, or when Axiom detaches its modules from the ISS to form an independent station, who owns the surrounding territory? On what legal basis?
The Space Settlement Institute has proposed a solution: Lunar Land Claims Recognition. Under this framework, the U.S. would commit in advance to recognizing private land claims on the Moon (and Mars) for any entity that establishes a permanent settlement and transportation system open to all paying passengers. Recognized land deeds could then be sold to finance the infrastructure a real community needs, creating a durable economic cycle that outlasts any single founder's fortune.
The legal basis for this approach, rooted in civil law's "use and occupation" principle rather than sovereign land grants, does not violate the Outer Space Treaty. The details are laid out in the Space Settlement Prize Act, proposed legislation that Congress could pass today. For a full treatment of the legal arguments, see the Institute's peer-reviewed article in the Journal of Air Law and Commerce.
These companies are building the rockets and habitats. What comes next, turning outposts into civilizations, requires a legal and economic framework. That is the work of the Space Settlement Institute. Read the FAQs to learn more.
The following companies were formerly on this list but have been acquired, gone public, suspended operations, or otherwise changed status.
