Who are the top startups of the lunar economy?

Lunar Outpost and Astrolab currently lead the lunar startup economy, with Interlune and Zeno Power behind them. The pattern is already clear: the strongest companies are building the practical infrastructure needed to move, power and operate hardware on the Moon, while the bigger mining and resource businesses are still waiting for demand to catch up.

Q1Is there actually a lunar economy yet?

Yes, but the lunar economy today is still mostly a government-funded market rather than an economy that can support itself.

NASA is now buying far more than occasional scientific rides to the Moon. Its current Moon Base program includes commercial landers, autonomous rovers, astronaut vehicles, power systems, resource prospecting and eventually communications infrastructure. NASA says it already has 17 lunar surface deliveries across multiple providers in its pipeline.

The size of the individual contracts has also changed. NASA recently committed almost $600 million across four additional lunar deliveries from Astrobotic, Firefly Aerospace and Intuitive Machines. It separately selected Lunar Outpost and Astrolab for rover programs worth roughly $220 million each. Blue Origin received $188 million for the first part of transporting those vehicles, with another $280.4 million available under an option.

Private demand remains much thinner. We still cannot point to a large network of lunar businesses routinely buying fuel, transportation, electricity or construction services from one another.

So there is enough demand to build serious companies already. But governments, especially NASA, are still creating most of it.

Q2What should count as a lunar economy startup?

A lunar economy startup should have a business that becomes more valuable as activity on or around the Moon grows.

That definition keeps the ranking focused. SpaceX obviously affects almost every serious Moon plan, but Starlink, Earth launch and other businesses account for most of SpaceX's activity. Blue Origin is privately owned and deeply involved in lunar transportation, but describing a company founded in 2000 and financed for decades by Jeff Bezos as a lunar startup would make the word almost meaningless.

We are more interested in younger companies building the pieces that repeated lunar activity will require: rovers, resource extraction, power, excavation, construction and transportation between orbits.

We also give more weight to evidence that is difficult to fake. A signed contract tells us more than a memorandum of understanding. Hardware being prepared for a mission tells us more than a rendering. A paying customer tells us more than a forecast saying a future lunar commodity could become a trillion-dollar market.

This produces a ranking that looks quite different from a list of the best-known Moon companies.

Q3Why are lunar startups suddenly getting much bigger contracts?

Lunar startups are getting much bigger contracts now because NASA has started buying repeatable infrastructure for its Moon Base program rather than treating every commercial Moon mission as a standalone experiment.

The rover market shows the change clearly. NASA selected Astrolab and Lunar Outpost to build and deliver lunar terrain vehicles, awarding roughly $219 million to Astrolab and $220 million to Lunar Outpost. These vehicles are expected to work autonomously when astronauts are absent and carry astronauts when crews are on the surface.

NASA is also ordering landings at a higher cadence. Its latest group of CLPS awards gave Astrobotic $297.9 million for two deliveries, Firefly Aerospace $144.2 million for another and Intuitive Machines $148.3 million for another. NASA described CLPS as a backbone of the Moon Base program and said additional opportunities would follow for landers, power demonstrations, imaging and lunar communications.

That changes what a startup can build around. A company developing a lunar rover no longer has to assume that a single experimental mission will be its entire addressable market. It can reasonably plan around several Moon missions, repeated government procurement and other companies that will need mobility once their payloads arrive.

The market is still small by aerospace standards, but these days a lunar infrastructure company can plausibly win a contract large enough to finance real production.

Where lunar procurement is expanding

Q4Why isn't Astrobotic in the lunar startup ranking anymore?

Astrobotic would have been near the top of this ranking earlier, but it is no longer an independent startup because Voyager Technologies completed its acquisition of the company.

The timing is revealing. Voyager agreed to buy Astrobotic shortly before NASA awarded the company another $297.9 million for two lunar deliveries. The transaction then closed, making Astrobotic part of publicly traded Voyager Technologies.

Astrobotic still tells us a lot about which lunar businesses are becoming valuable. Voyager specifically wanted Astrobotic's landing, lunar power and surface capabilities. The acquisition suggests that lunar infrastructure is beginning to attract larger aerospace platforms that would rather buy proven capabilities than develop every system internally.

The same distinction removes several other obvious names from our startup ranking. Intuitive Machines is publicly traded. Firefly Aerospace is also beyond the normal startup stage, and its Blue Ghost program already has a successful Moon landing behind it. Japan's ispace is publicly listed as well.

We use these companies as benchmarks instead. A private startup becomes much more interesting when its technology starts looking like something Firefly, Voyager, Intuitive Machines, ispace or another large operator could eventually need to buy, partner with or acquire.

Q5Is Lunar Outpost the strongest lunar startup right now?

Yes. Lunar Outpost currently has the strongest combination of a large Moon contract, a growing mission pipeline and a product that should be useful across many different lunar activities.

NASA selected Lunar Outpost's Pegasus rover under a task order worth about $220 million. Pegasus is designed to drive manually with astronauts, autonomously without them and through remote operation from Earth. NASA says the vehicle should be able to operate for up to a year.

That flexibility is important commercially. Astronauts may only spend limited periods on the surface, while a rover can keep moving scientific instruments, inspecting sites or preparing terrain between crew visits.

Lunar Outpost also has more going on than Pegasus. The company says it added four contracted lunar and cislunar missions over the previous year. Its published mission manifest includes Roo-ver for the Australian Space Agency, the LEAF biological experiment, additional MAPP rover missions and work connected to ESA.

Investors are also giving Lunar Outpost enough capital to grow beyond a small engineering shop. The company raised a $30 million Series B led by Industrious Ventures, following earlier venture rounds. Public funding databases put its total external funding above $50 million.

The biggest weakness is obvious: Lunar Outpost still needs to prove that its vehicles can work repeatedly on the Moon. But among independent lunar startups today, nobody else combines this amount of contracted demand with such a broadly useful surface product.

Q6Is Astrolab basically tied with Lunar Outpost?

Astrolab is very close to Lunar Outpost and could easily become the strongest lunar startup if its upcoming FLIP rover works on the Moon.

NASA awarded Astrolab roughly $219 million for CLV-1, its crew-capable lunar vehicle based on the company's FLEX rover architecture. That puts Astrolab in almost exactly the same financial position as Lunar Outpost inside NASA's rover procurement.

The more interesting difference is FLIP.

FLIP is a smaller rover that reuses technologies intended for Astrolab's larger vehicles, including batteries, wheels, avionics, sensors and software. NASA payloads are already booked on FLIP, which is due to travel aboard the Griffin-1 lander to the lunar South Pole.

So Astrolab has a chance to test important parts of its rover architecture on the actual Moon before its larger astronaut vehicle is needed.

The company also benefits from a deep relationship with Venturi Space, which is developing lunar wheels and batteries and recently announced a €250 million investment in a French facility focused partly on lunar and Martian mobility.

We give Lunar Outpost a slight edge for now because its commercial mission portfolio appears broader. Astrolab has the more obvious catalyst: successful FLIP operations could quickly erase that gap.

Q7Is Interlune really the leading lunar mining startup?

Yes. Interlune is currently the lunar resource startup with the best evidence that it is turning Moon mining into an engineering business rather than leaving it as a distant idea.

Helium-3 sounds like exactly the sort of resource that invites exaggerated Moon-economy claims. It is scarce on Earth, has uses in cryogenics, quantum systems and neutron detection, and could theoretically become useful for some future fusion technologies.

Interlune has been unusually disciplined about breaking that huge idea into smaller things it can actually test.

NASA awarded the company a $6.9 million contract to build technology that will heat lunar regolith, measure the gases released and test extraction techniques for helium-3 and hydrogen. Interlune has also signed commercial agreements involving helium-3 with companies including Maybell Quantum and Bluefors.

Lately, the technical evidence has become more interesting. Interlune demonstrated production of 99% pure helium-3 from terrestrial helium using its Cold Capture process. It then showed that it could implant helium into simulated lunar material and recover it with results comparable to Apollo samples. The company says that process can compress the equivalent of thousands of years of solar-wind exposure into hours, giving it a much better material for testing Moon-bound extraction equipment on Earth.

Interlune is also working with industrial equipment manufacturer Vermeer on excavation and Moon Base infrastructure, and with Astrolab on lunar resource-harvesting systems.

We still have no evidence that helium-3 can be mined on the Moon and returned profitably. But Interlune now has customers, NASA money, extraction technology and increasingly realistic test material. No other independent lunar mining startup we found currently puts all four together as convincingly.

Q8Is Zeno Power really a lunar startup if it also sells nuclear batteries elsewhere?

Zeno Power deserves to rank among the top lunar startups because surviving the lunar night is a problem that already exists, and Zeno can develop the same technology while selling into other markets.

Most solar-powered lunar hardware faces a brutal constraint. Away from unusually illuminated polar locations, lunar night can last roughly two Earth weeks. Permanently shadowed regions create an even harder power and heating problem.

Zeno is building compact radioisotope power systems that can provide electricity and heat without sunlight. NASA's current lunar technology program includes Harmonia, a Zeno-led system intended to keep surface hardware operating through the 14-day night and inside permanently shadowed regions.

The hardware has moved beyond early design. Zeno completed Harmonia's final design review and said the system delivered 3.5 times the originally specified power in its design performance. The company is now moving into fabrication ahead of terrestrial demonstration and eventual lunar qualification.

Firefly Aerospace has also selected Zeno technology for a Blue Ghost lunar mission designed to demonstrate radioisotope capabilities in extreme lunar temperatures.

Zeno raised a $50 million Series B and says it has secured more than $60 million in U.S. government contracts across space and maritime applications. That non-lunar demand helps rather than hurts our view of the company. Zeno does not need the Moon economy to develop perfectly on schedule to stay alive long enough to serve it.

Q9Is Argo Space becoming a real lunar economy company?

Argo Space has become much more credible lately because it has already put the first version of its water-based spacecraft architecture into orbit instead of waiting for lunar water before building a business.

Argo's long-term lunar idea is straightforward. Its spacecraft run on water. Initially that water comes from Earth. If lunar water can eventually be harvested cheaply, Argo wants to source propellant from the Moon and distribute it through cislunar space.

That lets Argo work backward from an existing customer rather than starting with a mine and hoping somebody eventually wants what comes out.

Its first spacecraft, Argonaut Demo, launched in 2026 carrying payloads associated with customers including Anduril, ThinkOrbital and Infinite Orbits. Argo says more than 75% of the spacecraft was designed and integrated internally, including its water propulsion, propellant tank, thermal systems and flight software.

The company has raised about $12 million through venture funding and government contracts. It has also announced work with ispace around lunar communications and transportation.

We would still separate Argo's current orbital business from its lunar resource claims. The company has not mined water on the Moon. Its claimed 10-times and 40-times propellant-delivery advantages for lunar-sourced water to LEO and GEO are company calculations rather than demonstrated economics.

Still, getting flight hardware into orbit moves Argo well ahead of a lunar fuel startup that only has terrestrial prototypes.

Q10Can Starpath Robotics actually build a lunar fuel business?

Starpath Robotics has a serious engineering program for making rocket oxidizer from lunar water, but its customer base is still several steps behind the hardware.

Starpath's basic plan is to excavate icy lunar material, extract the water, split it and produce large quantities of liquid oxygen. The company has talked about systems eventually producing around 1,000 tons of oxygen per year.

That scale sounds extreme today because lunar traffic is nowhere near large enough to consume 1,000 tons of locally produced oxidizer annually.

The engineering work is much more concrete. Starpath won roughly $838,000 across NASA's Break the Ice Lunar Challenge and finished second overall in the final competition. NASA later invited the company to test its excavation rover inside a thermal vacuum chamber at Marshall Space Flight Center. Starpath also raised a $12 million seed round led by 8VC and Fusion Fund.

So the main uncertainty is no longer whether Starpath can build interesting excavation hardware. We still do not know whether enough reusable landers and lunar vehicles will exist to buy industrial amounts of oxygen when Starpath is ready to produce it.

That pushes Starpath below Argo in our ranking today. Argo can sell orbital transportation before lunar resources exist, while Starpath's biggest business needs lunar traffic to become much denser.

Q11Are OffWorld and ICON serious lunar startups or mostly Earth companies with Moon projects?

OffWorld and ICON both deserve a place in the lunar economy, although their terrestrial businesses are currently more mature than their lunar ones.

OffWorld builds autonomous mining robots for harsh industrial environments on Earth and is adapting the same architecture for lunar excavation. NASA's recent TechPort records describe a system of modular robotic machines that could excavate icy lunar regolith while sharing software and autonomy across the fleet.

The terrestrial connection is useful. OffWorld can improve digging, autonomy, maintenance and fleet coordination in real mines rather than keeping an engineering team alive purely on lunar grants.

ICON approaches the Moon from construction. NASA awarded the company $57.2 million to develop Olympus, a system intended to turn lunar regolith into infrastructure such as landing pads, roads and eventually structures. ICON has also tested the behavior of lunar simulant in partial gravity and already operates large-scale robotic construction systems on Earth.

Neither company has yet reached the point where Lunar Outpost or Astrolab are today. There is no nine-figure lunar excavation or construction service order waiting for them.

Their technologies probably become more valuable later, once enough equipment has landed to justify roads, prepared surfaces, mines and permanent facilities.

OffWorld and ICON's lunar position today

Q12Is Ethos Space Resources already worth taking seriously?

Ethos Space Resources is worth watching now, but it is much too early to rank beside companies already holding major lunar contracts.

Ethos joined Y Combinator's Summer 2026 batch with only a tiny team and an unusually ambitious goal: process lunar regolith into materials such as silicon, oxygen and construction feedstock so that future space infrastructure does not have to be launched entirely from Earth.

The company says it has completed a NASA contract, accumulated about $1 billion in letters of intent and is targeting a Moon mission in 2028.

We would treat the $1 billion figure cautiously. Letters of intent are very different from booked revenue, especially when the product depends on industrial activity that does not yet exist on the Moon.

Still, Ethos is interesting because it is arriving at the exact moment when NASA is shifting from individual lunar missions toward surface infrastructure. If Moon operations become frequent, locally produced construction material, oxygen and eventually solar-grade silicon could become extremely valuable.

For now, Ethos belongs on the watchlist rather than near the top of the ranking.

Q13Why do rover and power startups rank above Moon mining startups today?

Rover and power startups rank higher because customers already need those products, while large-scale lunar mining still depends on a much busier Moon than the one we have now.

Consider the sequence.

A lander can carry a scientific payload today. That payload can immediately benefit from a rover. A rover staying on the surface for months can immediately benefit from better power. More missions can immediately create demand for communications and navigation.

Large-scale resource production comes later. A lunar oxygen plant becomes much more attractive once reusable spacecraft are arriving often enough to consume significant propellant. Large excavation fleets become useful when somebody needs a continuous flow of material. Roads and industrial construction become compelling when enough vehicles and facilities are operating nearby.

We can already see this gap in spending. Mobility programs are attracting awards of roughly $200 million per company. Interlune's highly credible resource-development contract from NASA is $6.9 million. Starpath's major disclosed venture round is $12 million.

Resource companies may eventually build the larger businesses. Fuel, raw materials and construction can become recurring commodities in a way that a single rover cannot.

Today, however, the money tells us where lunar activity really is. We are still building the equipment needed to reach, move around and stay alive on the Moon before we build a major extraction industry.

Q14What would change the lunar startup ranking fastest?

Actual Moon operations will change this lunar startup ranking much faster than another venture round.

Astrolab is the clearest example. FLIP working successfully on the lunar surface would give Astrolab something neither Lunar Outpost nor most of the companies below it currently have: operational experience with its own rover technology on the Moon.

Lunar Outpost has several missions that could similarly turn its large contract portfolio into genuine surface heritage.

Interlune has a different hurdle. Its recent helium-3 work on Earth is technically interesting, but the company needs to demonstrate extraction processes using actual lunar material in the lunar environment. Its NASA payload is designed to move it toward exactly that point.

Zeno needs its nuclear battery technology to progress from terrestrial testing into flight-qualified hardware and then survive real lunar conditions.

Argo has already crossed one milestone by getting its first spacecraft into orbit. The next meaningful jump would come from demonstrating the parts of its water-based transportation system that can eventually support refueling and cislunar logistics.

We would pay much less attention to who announces the next $20 million round. At this stage, one successful mission can tell us more about a lunar startup than several years of fundraising.

Q15Who are the top startups of the lunar economy right now?

Lunar Outpost and Astrolab are the two strongest independent lunar startups today, with Interlune and Zeno Power forming a very credible second group.

Lunar Outpost takes our top spot because it has a roughly $220 million NASA rover program, several other contracted missions, fresh venture financing and a product that can be useful for science, logistics, resource prospecting and astronaut transportation.

Astrolab is almost tied. Its large NASA rover program gives it the same basic validation, while the upcoming FLIP mission gives it a near-term chance to put its own mobility technology on the Moon.

Interlune ranks third because it currently looks like the best lunar resource startup. As seen above, its case now includes NASA-funded extraction hardware, commercial helium-3 customers, industrial excavation partners and very recent progress recreating lunar-like helium-bearing material for terrestrial tests.

Zeno Power comes fourth. Persistent power is already useful before large-scale mining begins, and Zeno has enough non-lunar business to keep developing its hardware even if Moon schedules slip.

Argo moves into fifth place after getting its first water-based spacecraft architecture into orbit. The actual lunar water part remains unproven, but there is now a real transportation business underneath the long-term resource thesis.

Starpath, OffWorld and ICON follow. We take all three seriously, although the Moon needs more industrial activity before their largest markets really open.

Ethos Space Resources is our most interesting very-early-stage company. It is trying to solve a problem that barely exists commercially today, but local manufacturing could become one of the biggest lunar businesses if surface infrastructure grows far beyond the current mission cadence.

The ranking also says something broader about the lunar economy these days. The companies furthest ahead are mostly building practical infrastructure: vehicles that move things, systems that keep hardware alive, machines that dig and technology that can eventually turn local material into something useful.

The spectacular part of the Moon economy may eventually be mining helium-3, producing fuel or manufacturing infrastructure from lunar rock. For now, the winners are much closer to the ground.
