7 Space ETFs for the Next Frontier of Investing

Space might not be the final frontier in investing, but it very well could be the next great frontier. And those looking to own the industry can harness its potential through a rapidly growing number of space ETFs.

The space industry is hardly new—commercial satellite launches have been around since the 1960s—but it has come to the forefront of late because of the looming initial public offering (IPO) of SpaceX. Elon Musk’s aerospace manufacturing company, which also provides satellite communications and launch services, is targeting a valuation of nearly $2 trillion and claims a total addressable market (TAM) of $28.5 trillion.

While some out there might take the latter figure with a grain of salt given the distance between some of Musk’s previous claims and reality, there’s little question that space represents a massive opportunity. McKinsey, for instance, estimates the global space economy will be worth $1.8 trillion by 2035, or about triple the $630 billion it was worth in 2023.

Like with many emergent technologies, investors could try to pick winners and hope they don’t hitch their wagons to the names that eventually fizzle out … or they could purchase diversified exchange-traded funds to profit from the growth of the broader industry.

Let me introduce you to some of the most prominent space ETFs you can buy right now. These funds already hold a variety of space-related companies—and most, if not all, are very likely to own SpaceX at some point after the company goes public in June.

Our Look at Wall Street’s Top Space ETFs

---

While the commercial space industry has existed in some form since before most of us were born, space ETFs have really only existed for less than a decade.

And they typically share a few common traits:

• Similar holdings. The space industry, while hardly nascent, isn’t exactly widespread. Most of these ETFs hold only a few dozen companies, and many of them play in the same pool.
• Similar sector weights. Along the same lines, space ETFs tend to allocate a huge chunk of their assets to industrial/defense companies, with the rest going to communications and technology firms.
• Similar fees. “Thematic” funds that focus on specific investment opportunities that span a few different sectors often charge more than broad-market funds. All of the funds here assess annual fees between 0.35% and 0.75% annually, with several charging that top-end number.

That doesn’t mean there aren’t meaningful variations now—but like with many thematic funds, these space ETFs will likely differentiate themselves even more if and when the space industry expands.

With that, let’s look at some of the most notable space ETFs you can buy right now.

ETFs are listed in order of assets under management (AUM), from largest to smallest.

1. Procure Space ETF

---

• Inception: April 11, 2019
• Assets under management: $1.1 billion
• Expense ratio: 0.75%, or $7.50 per year on every $1,000 invested

The largest space ETF at the moment also happens to be one of the oldest: Procure Space ETF (UFO), from market veteran Andrew Chanin’s ETF firm, ProcureAM.

The Procure Space ETF tracks the VettaFi Space Index, which allocates at least 80% of its weight to “companies that derive a majority of revenues from space-related industries, including those companies utilizing satellite technology.” Among those industries?

• Ground equipment manufacturing dependent upon satellite systems
• Rocket and satellite manufacturing and operation
• Satellite-based telecommunications, radio, and television broadcasting
• Space industry segments—space-based imagery and intelligence services
• Space technology and hardware

UFO’s portfolio currently stands at around 50 stocks. From a more traditional sector perspective, industrials make up half of UFO’s assets, followed by communications (30%) and technology (20%). This is also a global fund, with the U.S. accounting for about two-thirds of assets, and a handful of other countries—including Canada, the Netherlands, and Japan, among others—making up the rest.

Right now, top holdings include the likes of Planet Labs (PL), an Earth imaging company; EchoStar (SATS), which provides satellite communications solutions, wireless communications, and content delivery; and longtime satellite radio firm SiriusXM Holdings (SIRI).

Procure also spells out how the fund could evolve over time if and when new space businesses become possible and viable. Among the potential industries the ETF could eventually reflect are space tourism, space-based military and defense systems, space colonization, and space resource exploration and extraction.

The Procure Space ETF hit the markets seven years ago, and it might have been ahead of its time. In a recent Reuters report, Chanin noted that “UFO was labeled the worst ETF launch of the year by Morningstar in 2019.” It boasted less than $100 million in AUM for most of its first six years of trading and only had $170 million as of the start of 2026.

Today, UFO boasts more than five times those assets, making it the largest space ETF out there.

2. Ark Space & Defense Innovation ETF

---

• Inception: March 30, 2021
• Assets under management: $1.0 billion
• Expense ratio: 0.75%, or $7.50 per year on every $1,000 invested

Cathie Wood’s actively managed Ark Space & Defense Innovation ETF (ARKX) is another relatively early entrant into the space ETF race, launching in 2021 and amassing the second-highest amount of assets under management.

When I initially covered this fund’s launch years ago, it was known as the ARK Space Exploration & Innovation ETF, but in 2025, it changed its moniker to Space & Defense—but this didn’t herald a strategy pivot so much as it better reflected what the fund already owned.

ARKX holds companies focused on either space or defense innovation, which ARK Investment Management defines as “leading, enabling, or benefiting from technologically enabled products and/or services that occur beyond the surface of the Earth.” The 33-stock portfolio focuses on technologies such as autonomous mobility, intelligent devices, 3D printing, advanced batteries, reusable rockets (a clear “in” for SpaceX), and more.

Similar to UFO, ARKX is big on industrials (55%) and technology (27%), though the rest of the fund spreads its assets across not just communication services stocks, but also consumer discretionary and even healthcare companies. Rocket Lab (RKLB), a direct competitor to SpaceX, is an unsurprising top holding right now. But the company is also thick in defense companies such as L3Harris Technologies (LHX), Kratos Defense & Security Solutions (KTOS), and drone specialist AeroVironment (AVAV).

Perhaps the most initially head-scratching component is top-10 holding Deere (DE) … but the tractor maker partnered with SpaceX in 2024 to provide satellite communications to farmers. So there’s that.

Because ARKX and other ARK Invest ETFs are actively managed, it’s important to keep tabs on personnel. On that front, there are some concerns to keep in mind.

“In recent years, the firm has taken concrete steps to reduce its reliance on [Wood],” Morningstar Principal Robby Greengold says. “But the firm hasn’t yet made much tangible progress in easing its key-person risk or strengthening its risk culture, warranting a Below Average Parent rating. The firm’s analysts often don’t stick around. Wood remains the only team member with hands-on portfolio management experience. The firm has struggled to develop and retain investment team talent; only four of its analysts have tenures greater than five years.”

3. Spear Alpha ETF

---

• Inception: Aug. 2, 2021
• Assets under management: $240.0 million
• Expense ratio: 0.75%, or $7.50 per year on every $1,000 invested

Launching in the same year to far less fanfare was the Spear Alpha ETF (SPRX), which is the lone exchange-traded fund under Ivana Delevska’s Spear Funds umbrella.

The lack of hullabaloo then, and now, is largely because this isn’t a pure-play space fund—instead, it invests in “companies benefiting from breakthrough trends in industrial technology.” That includes space exploration, as well as other enticing growth trends such as artificial intelligence (AI), robotics, and automation. It also invests in enterprise digitalization, energy transition, and photonics and additive manufacturing.

Spear Alpha ETF attempts to harness all of these themes across a tight portfolio of around 30 stocks, and it does so predominantly through the technology sector. Tech stocks—including engineered materials firm Coherent (COHR), and semiconductor firms Astera Labs (ALAB) and ARM Holdings (ARM)—make up about 85% of assets. The remaining 15% is split between industrials and financial services.

There’s a little holdings overlap with some of these other space ETFs, including Rocket Lab and Kratos, but this isn’t so much a direct line to the cosmos as it is a way to invest in numerous emerging technologies … including space.

4. State Street SPDR S&P Kensho Final Frontiers ETF

---

• Inception: Oct. 22, 2018
• Assets under management: $231.6 million
• Expense ratio: 0.45%, or $4.50 per year on every $1,000 invested

The State Street SPDR S&P Kensho Final Frontiers ETF (ROKT) actually predates all of the other funds on this list, and it’s also one of the least expensive ways to invest in space.

But you’ll want to pay close attention to one of the words in its name: “frontiers.” As in “more than one.” Let’s take a look at the product description page (emphasis mine):

“[ROKT] seeks to track an index utilizing artificial intelligence and a quantitative weighting methodology to capture companies whose products and services are driving innovation behind the exploration of the final frontiers, which includes the areas of outer space and the deep sea.”

OK, so it’s not a pure play on the Milky Way. But you’re still getting a ton of outer-space exposure in this 35-stock portfolio.

Top holdings include previously mentioned Planet Labs and Rocket Lab, as well as aerospace manufacturer and space infrastructure tech firm Redwire (RDW), global satellite communications network operator Iridium Communications (IRDM), and defense-and-space firm Voyager Technologies (VOYG), which among other things is jointly developing a low-Earth orbit (LEO) space station, Starlab, alongside Airbus, Mitsubishi, and MDA Space.

Industrial stocks broadly, and defense companies specifically, are big parts of most space ETFs. But they’re an even greater influence on ROKT than they are elsewhere, as State Street’s ETF allocates two-thirds of assets to the sector. I say that to say this: U.S. and other nations’ defense spending will also have a say in these funds’ performance, but perhaps Final Frontiers more than most.

To its credit, ROKT has been one of the best-performing space ETFs of the past few years.

5. Roundhill Space & Technology ETF

---

• Inception: March 5, 2026
• Assets under management: $75.8 million
• Expense ratio: 0.75%, or $7.50 per year on every $1,000 invested

Roundhill Space & Technology ETF (MARS), another actively managed product to rival ARKX, debuted just a couple months ago and has cobbled together just more than $75 million in assets so far.

This is a pure-play fund that “seeks exposure to the space economy and enabling technologies, focusing on space companies powering industries reliant on space infrastructure.” That means these companies are enabling things you’d expect, such as GPS, internet, and weather forecasting … but also some things you might not, such as agriculture, banking, and healthcare.

A seven-manager team oversees a 30-stock portfolio that owns a bunch of familiar names, such as Rocket Lab, EchoStar, satellite internet firm Viasat (VSAT), and launch vehicle developer Firefly Aerospace (FLY). Industrials come in at 55% of assets, with communications companies at 26% and technology accounting for the rest.

Because MARS is run by an investment committee and not a rules-based index, SpaceX inclusion is not as much a lock as it might be for the other funds—management would have to consider whether to own it. On the flip side, if MARS does end up including SpaceX, its concentration in the portfolio could differ from other funds whose weights are determined by market cap, revenues from space, or other factors.

6. Global X Space Tech ETF

---

• Inception: April 14, 2026
• Assets under management: $33.7 million
• Expense ratio: 0.50%, or $5.00 per year on every $1,000 invested

Global X Space Tech ETF (ORBX) is one of the newest space ETFs, launched in April with a 50-basis-point fee that undercuts most of the pure-play interstellar funds. (A basis point is one one-hundredth of a percentage point.)

ORBX tracks the Global X Space Tech Index, which owns companies that earn at least 50% of their revenue from “critical segments of the upstream and downstream space sectors.” This includes rocket launch systems, reusable rockets, mission-critical space technology and components, satellite-enabled telecommunications and data, space transportation and exploration, and even space tourism.

“In a category where broader tech, telecom, or defense exposure can dilute the theme, ORBX aims to give investors a cleaner, more focused way to access the fast-commercializing space economy,” says Tejas Dessai, VP, Director of Thematic Research at Global X.

ORBX is another tight portfolio, owning just 30 stocks right now. It’s even more heavily weighted in industrials than ROKT, at 70% of assets. The rest belongs to tech and communication stocks. The names should be familiar too: Rocket Lab. Planet Labs. Iridium. Viasat. It also owns space exploration firm Intuitive Machines (LUNR)—another common large holding among space ETFs.

Like many of the funds on this list, we can expect Global X Space Tech ETF to get a bite of SpaceX at some point after it launches. But a big question (for all of them) is when?

Says Dessai about Global X’s product: “ORBX does not require investors to wait for the next quarterly rebalance to gain exposure to major new listings. Through its Fast Entry process, qualifying IPOs can be added on an accelerated timeline. In some cases, it could be less than two weeks. New IPOs are reviewed twice a month, and if a company meets the index criteria, it can be added three business days after the evaluation date.”

7. Corgi Space and Satellite Communications ETF

---

• Inception: May 6, 2026
• Assets under management: $3.2 million
• Expense ratio: 0.35%, or $3.50 per year on every $1,000 invested

Last, and certainly least for the moment, is the actively managed Corgi Space and Satellite Communications ETF (DIPR), but it can hardly be blamed for its thin $3 million in assets—as I write this, it has only been trading for a few weeks.

DIPR is a pure-play space ETF—one that in theory could still hold a wider world of space investments, but for now is communicating a specific focus on, well, satellites and communications. Says provider CorgiFunds:

“The number of active satellites in orbit has approximately tripled since 2019. DIPR provides exposure across the space and satellite value chain: constellation operators providing broadband and Internet of Things (IoT) connectivity, launch companies, satellite manufacturers, Earth observation and geospatial platforms, and ground equipment and software.”

Unsurprisingly, Rocket Lab, Planet Labs, and Viasat sit near the top of this 30-stock portfolio. Also prominently placed are defense giant Lockheed Martin (LMT) and satellite manufacturer AST SpaceMobile (ASTS). Industrials are 62% of assets, followed by technology (24%) and communication services (14%).

But the most noteworthy feature of CorgiFunds’ ETF is its fee. Despite being run by human managers, DIPR is charging just 0.35% annually, which is lower than all other space ETFs on this list—active and index alike.
