The space economy is no longer the exclusive playground of government agencies and defense contractors. In 2025, it is a rapidly expanding commercial sector projected to exceed $630 billion in annual revenue, with forecasts from Morgan Stanley and others suggesting it could balloon toward $1 trillion by the early 2030s. For retail investors watching from the sidelines, the question is no longer whether the space economy matters -- it is how to gain exposure to it intelligently.
This guide walks through the major publicly traded vehicles for investing in space, from broad ETFs to individual pure-play stocks and defense-adjacent incumbents. We will look at each with clear eyes, not hype goggles.
Space-Focused ETFs: Broad Exposure, Lower Risk
If you want diversified exposure to the space sector without betting on a single company, exchange-traded funds are the natural starting point.
ARK Space Exploration & Innovation ETF (ARKX)
Launched in March 2021 by Cathie Wood's ARK Invest, ARKX was one of the first ETFs explicitly targeting space. It tracks companies involved in orbital and sub-orbital aerospace, enabling technologies, and space-related applications. Top holdings typically include Trimble, Kratos Defense, Iridium Communications, and Rocket Lab, among others.
The catch? ARKX has drawn criticism for including companies that are only tangentially related to space -- think agricultural drone companies and 3D printing firms. Its expense ratio of 0.75% is also on the higher side for a thematic ETF. Since inception, its performance has been volatile, largely tracking the broader growth-tech selloff of 2022 and the partial recovery thereafter.
That said, ARKX remains the most recognized space ETF and offers a curated (if loosely defined) basket of space-adjacent names. If ARK's thesis on disruptive innovation appeals to you, this is their space-flavored expression of it.
Procure Space ETF (UFO)
The Procure Space ETF, trading under the memorable ticker UFO, takes a more rigorous approach to defining "space company." It tracks the S-Network Space Index, which requires that constituent companies derive at least 50% of their revenue from space-related activities. This gives UFO a tighter focus on satellite operators, launch providers, and ground equipment manufacturers.
Holdings have historically included SES, Eutelsat, Iridium, and Maxar Technologies (before its acquisition by Advent International). UFO's expense ratio sits at around 0.75% as well, and its performance has been uneven -- dragged down by the broader struggles of legacy satellite operators while buoyed by growing interest in new space.
For investors who want purer space exposure than ARKX provides, UFO is worth examining, though its liquidity can be thinner given its smaller asset base.
Pure-Play Space Stocks: Higher Risk, Higher Conviction
Individual space stocks offer the possibility of outsized returns -- and outsized losses. Here is a look at the most prominent names.
Rocket Lab USA (RKLB)
Rocket Lab has arguably become the most credible pure-play space stock available to public investors. Its Electron rocket is the second most frequently launched U.S. rocket behind SpaceX's Falcon 9, and the company has expanded aggressively into spacecraft manufacturing, satellite components, and its next-generation medium-lift Neutron rocket.
Revenue has been growing steadily, with the company posting over $245 million in 2023 revenue and continuing to grow in 2024. The Neutron rocket, targeting a 2025-2026 first launch, could be transformative -- opening the door to mega-constellation deployment and competing for national security launch contracts. The backlog is healthy, government contracts are diversified, and CEO Peter Beck has a track record of execution.
The risk? Neutron development is expensive, and any significant delays could pressure the stock. Rocket Lab is not yet profitable on a GAAP basis, though its path to profitability is more visible than most peers.
Virgin Galactic (SPCE)
Once the darling of the space tourism narrative, Virgin Galactic has had a brutal few years. After finally conducting commercial suborbital flights in mid-2023, the company paused operations to develop its next-generation Delta-class vehicles. Revenue has been minimal, cash burn has been significant, and the stock has lost over 95% of its value from its 2021 peak.
Virgin Galactic represents a cautionary tale about valuing companies on narrative rather than fundamentals. The space tourism market may eventually materialize at scale, but Virgin Galactic's execution risk is enormous. Investors should approach with extreme caution, if at all.
Intuitive Machines (LUNR)
Intuitive Machines grabbed headlines in February 2024 when its Odysseus lander became the first commercially built spacecraft to achieve a soft landing on the Moon -- even if it tipped over on arrival. The company has a pipeline of NASA Commercial Lunar Payload Services (CLPS) contracts and is positioning itself as a key player in the lunar economy.
The stock has been volatile, spiking around mission milestones and pulling back during quiet periods. Revenue is heavily dependent on NASA contracts, which introduces both stability (government backing) and concentration risk. The company is early-stage in its financial maturity, but its position in the emerging lunar services market is genuinely unique among public companies.
Planet Labs (PL)
Planet Labs operates the largest fleet of Earth observation satellites in history, imaging the entire landmass of Earth daily. The company serves agriculture, forestry, government intelligence, and disaster response markets with its data products.
Revenue has been growing but the path to profitability has been slower than investors hoped. The stock trades well below its SPAC-era highs. Still, the secular demand for geospatial data is enormous, and Planet's data moat is real. If the company can improve unit economics and expand its government contract base, the long-term thesis holds water.
Spire Global (SPIR) and BlackSky Technology (BKSY)
Both Spire and BlackSky are smaller-cap space data companies that went public via SPACs. Spire operates a constellation focused on weather, maritime, and aviation data; BlackSky provides real-time geospatial intelligence with rapid revisit times. Both face the common challenge of SPAC-era companies: they need to prove that their technology can generate sustainable, growing revenue streams at scale. Liquidity is thinner and volatility is higher, making them suitable only for investors with high risk tolerance and long time horizons.
Defense-Adjacent Giants: The Steady Hands
Not all space investment means buying small-cap moonshots. Some of the most significant space revenue flows through large defense contractors.
Lockheed Martin (LMT)
Lockheed Martin is deeply embedded in space through its Space division, which builds satellites, missile warning systems, and the Orion crew capsule for NASA's Artemis program. Space revenue represents a meaningful but not dominant share of total revenue, making Lockheed a way to get space exposure with the stability of a diversified defense prime.
Northrop Grumman (NOC)
Northrop Grumman builds solid rocket boosters for the Space Launch System, operates the Cygnus cargo spacecraft for ISS resupply, and has a growing space-based missile tracking portfolio. Like Lockheed, it offers space exposure wrapped in a blue-chip defense package.
L3Harris Technologies (LHX)
L3Harris is a key supplier of space-based sensors, communication payloads, and ground systems. Its acquisition of Aerojet Rocketdyne in 2023 added rocket propulsion to its portfolio, making it one of the more vertically integrated space suppliers among the defense primes.
The Long-Term Thesis and the Risks
The bull case for space investing rests on several secular trends: declining launch costs (down roughly 10x in two decades), the explosion of satellite-based services, growing national security demand, and the early stages of a lunar economy. The space economy is not speculative science fiction -- it is infrastructure being built in real-time.
The risks are equally real. Many pure-play space companies are pre-profit or early-revenue. Regulatory environments can shift. Launch failures destroy both hardware and investor confidence. And the sector is prone to hype cycles, as the 2021 SPAC bubble painfully demonstrated.
For most investors, a sensible approach might combine a small allocation to a space ETF for broad exposure with selective positions in individual names where you have high conviction. The defense primes offer ballast. The pure-plays offer upside -- and volatility.
The space economy is being built. The question is not if it will generate enormous value, but which companies will capture it, and at what price.
