Asteroid Mining Companies You Can Invest in Today (2025)
November 2025 update
Quick reality check: can you really invest in asteroid mining yet?
If you’re hoping for a tidy list of companies that are actively mining asteroids and posting big profits, here’s the honest answer:
No company is commercially mining asteroids yet.
Most “true” asteroid-mining startups are private and not available to everyday investors.
However, there are several public companies whose business models revolve around lunar resources, in-space logistics, and off-world infrastructure. These are the closest realistic proxies for an “asteroid mining” investment theme.
For now, asteroid mining investing is really early-stage space-resources speculation. You’re betting on the long-term space economy, not on near-term cash flows from platinum-rich rocks.
The asteroid mining dream, in one paragraph
Asteroids—especially metal-rich types—contain enormous quantities of:
Platinum-group metals
Nickel, cobalt, and other critical minerals
Water ice that can be turned into rocket fuel and life-support resources
The long-term vision:
Mine water and metals in space instead of dragging everything up from Earth
Use those resources to fuel satellites, lunar bases, and deep-space missions
Dramatically reduce mission costs by avoiding Earth’s gravity well for every kilogram of material
That “trillion-dollar space gold rush” storyline is what drives the excitement, even though the technology and economics are still being proven.
What happened to the first asteroid mining boom?
If you read older pieces on asteroid mining, you’ll see two names over and over: Planetary Resources and Deep Space Industries.
They were real, ambitious companies—and they’re also cautionary tales:
Both raised substantial capital and did valuable R&D, but they didn’t reach commercial asteroid mining.
Planetary Resources was eventually acquired by ConsenSys (a blockchain company), and its asteroid-mining ambitions faded away.
Deep Space Industries was acquired by Bradford Space, which shifted the focus away from pure asteroid mining toward more general space technology.
The takeaway for investors:
This is extremely long-term, high-risk deep tech.
Even well-funded pioneers can fail or be absorbed before they get close to mining an asteroid.
You should treat the whole space-resources theme as venture-style speculation, not as a blue-chip mining sector.
The new wave: private asteroid-mining and space-resource startups
A second generation of companies is now tackling space resources with cheaper launch options and new technology. Most of these are still private, but they’re important to track if you’re serious about the theme.
AstroForge (private)
U.S. startup focused directly on mining asteroids for platinum-group metals.
Has raised tens of millions of dollars for multiple missions, including a refinery-test cubesat and a planned asteroid-orbit mission.
Early missions have faced communication problems and failures, underscoring how difficult this is.
Investment status: Private, venture-backed. Not available to ordinary retail investors.
TransAstra (private)
Developing “optical mining” techniques that use concentrated sunlight to extract volatiles (especially water) from asteroids and other small bodies.
Building mission architectures for in-space resource extraction and propellant production.
Investment status: Private. Typically accessible only through private rounds for institutional or accredited investors.
Karman+ (private)
Working on space mining concepts focused on supplying water and fuel from asteroids to the in-space economy.
Planning a first mission toward the late 2020s that aims to characterize asteroid resources and demonstrate key technologies.
Investment status: Private, not publicly traded.
Asteroid Mining Corporation (private)
UK-based company developing robotic systems like a hexapod climbing robot for space-resource exploration.
Working with lunar-focused partners on future demonstration missions, positioning itself as part of the early mining value chain.
Investment status: Private.
OffWorld (private)
Builds AI-driven, swarm robotic mining systems initially for use on Earth, but with a roadmap to the Moon, asteroids, and Mars.
Focused on fleets of autonomous robots performing heavy industrial tasks in hostile environments.
Investment status: Private.
So what can you actually invest in today?
If you’re a typical investor using a standard brokerage account, your direct options are public companies that are part of the emerging space-resources infrastructure, rather than “asteroid miners” per se.
Think:
Lunar resource development
Lunar landers and surface logistics
In-space transportation, tugs, and refueling
Space robotics and exploration systems
Here are some of the most relevant public names as of 2025.
Public companies closest to asteroid and space-resource mining
ispace, inc. (Tokyo: 9348)
What it does:
ispace is a lunar resource development company. It designs and builds robotic landers and rovers that transport payloads to the Moon and support resource exploration.
Key points:
Sells payload and data services for customers that want to operate on the lunar surface.
Runs missions aimed at exploring the Moon’s regolith and demonstrating early resource transactions, including tiny lunar-material purchases by space agencies.
Partners with robotics and mining-focused firms, making it a central player in the early lunar-resources ecosystem.
Why it matters for asteroid mining investors:
While ispace is focused on the Moon rather than asteroids, the technologies for landing, moving, and processing material on an airless body are directly relevant to any future asteroid-mining efforts. It is one of the clearest public “space-resources pure plays.”
How you invest:
Traded on the Tokyo Stock Exchange under the ticker 9348. You’ll usually need a broker that supports Japanese equities or an intermediary product that gives you access.
Momentus Inc. (Nasdaq: MNTS)
What it does:
Momentus provides in-space transportation and infrastructure services. Its orbital service vehicles (“space tugs”) are designed to move satellites and payloads between orbits using water-based propulsion.
Key points:
Uses water as propellant, which aligns conceptually with in-space refueling from mined water resources in the future.
Provides orbit-raising, orbital transfer, and potentially other in-space services like hosting payloads.
Positions itself as a key piece of the in-space logistics and transport layer.
Why it matters for asteroid mining investors:
Asteroid mining assumes a future where moving mass around the inner solar system becomes relatively routine. A company working on in-space logistics and refueling concepts is a natural infrastructure bet on that future, even if it never mines anything itself.
How you invest:
Listed on the Nasdaq under ticker MNTS.
Intuitive Machines (Nasdaq: LUNR)
What it does:
Intuitive Machines builds robotic lunar landers and associated technology. It is one of the commercial providers delivering payloads to the Moon under government lunar-program contracts.
Key points:
Has executed commercial lunar lander missions, showing that its hardware can reach and land on the Moon.
Targeting lunar south-pole regions believed to host water ice—a key resource for in-space fuel and life support.
One of its future missions is slated to carry a payload from AstroForge as a ride-along, linking an asteroid-mining startup with Intuitive Machines’ lunar flight hardware.
Why it matters for asteroid mining investors:
Intuitive Machines gives you exposure to lunar surface access and early resource-centric missions, which are foundational for the broader space-resources economy. Lander companies are essential if you believe space mining of any kind is going to be viable.
How you invest:
Listed on the Nasdaq under ticker LUNR.
How to think about risk and time horizon
Investing in space-resources and asteroid-adjacent companies is very different from buying established mining stocks.
Key realities:
No asteroid-mining revenue yet
All meaningful activity is still in research, technology demonstration, and early missions. Even “resource sales” from the Moon so far are small, symbolic transactions.Extreme technical risk
Missions frequently fail or underperform. You’re betting on hardware that pushes the limits of engineering and often flies for the first time.Funding and dilution risk
Many of these companies are pre-profit, highly capital-intensive, and likely to raise more equity, which can dilute existing shareholders.Legal and regulatory uncertainty
International law around ownership and commercialization of off-world resources is still evolving. Future treaties and regulations could change business models or profitability.
In short: these are speculative, long-duration bets. You should be comfortable with volatility, setbacks, and the possibility of total loss on individual names.
Building a “space resources” themed portfolio
If you want exposure without betting everything on a single company, you can think in layers:
1. Core space-resources and infrastructure plays
These are higher-risk, more thematically pure:
ispace (9348) – lunar resource development and payload delivery
Intuitive Machines (LUNR) – lunar landers and south-pole missions
Momentus (MNTS) – in-space transportation and water-propellant tugs
These sit closest to the future off-world mining stack.
2. Private companies to watch (but not yet investable)
These are important if you’re tracking the space-resources sector:
AstroForge – asteroid PGM mining concepts and demonstration missions
TransAstra – optical mining and in-space propellant production
Karman+ – asteroid water and fuel concepts
Asteroid Mining Corporation – robotics for space-resource exploration
OffWorld – AI robotic mining fleets for Earth and beyond
They might go public, get acquired by bigger players, or stay private. Watching their partnerships and progress can help you anticipate where public companies might get involved.
3. Broader space and aerospace exposure
You can also consider:
Launch providers
Satellite manufacturers and operators
General space-infrastructure and aerospace companies
Space-themed funds or products (if available in your region)
These aren’t asteroid-specific, but they benefit from overall growth in the space economy, which is a prerequisite for space mining to become meaningful.
Due-diligence checklist for asteroid-adjacent stocks
Before putting money into any of these names, ask:
What is this company’s actual revenue source today? Is it government contracts, commercial services, or mostly promises?
How much runway do they have (cash vs. annual burn)? How likely are future equity raises?
Are they genuinely focused on space resources and infrastructure, or are they a generic space company being marketed as a mining play?
What milestones would change your view? For example:
A successful landing or orbital rendezvous
A contract to deliver samples or resources
A strategic partnership with a larger aerospace company
Document your answers so you’re not just reacting emotionally to headlines.
Practical risk management tips
If you decide to invest in this theme:
Keep position sizes small relative to your overall portfolio.
Consider treating them as “moonshot” allocations rather than core holdings.
Diversify across a few related names instead of going all-in on one.
Set realistic expectations: think in decades, not months.
Be prepared for high volatility and occasional scary drawdowns.
The bottom line
If your question is, “Which asteroid mining companies can I buy stock in today?” the precise answer is:
There are currently no publicly traded companies that are actively and profitably mining asteroids.
What you can invest in are:
Lunar and space-resource companies like ispace, Intuitive Machines, and Momentus, which are building key pieces of the off-world mining infrastructure.
A broader set of space and aerospace companies that stand to benefit if the space economy grows into the trillion-dollar industry many analysts expect.
This is a frontier sector. The upside case is enormous, but the path is uncertain. If you choose to invest, do it with your eyes open, your homework done, and your risk sized appropriately.
