Is Space the Next Big Investment Opportunity?

The best space ETFs to buy in 2026 are no longer just for sci-fi enthusiasts and risk-hungry speculators. They’re for any investor who wants exposure to one of the fastest-growing sectors of the global economy — and the data backs it up.

One fund returned over +101% in a single year. Another crossed $2.66 billion in assets under management. And a third is actively managed by one of the most well-known names in disruptive tech investing.

Space is no longer a government project. It’s a multi-trillion-dollar commercial industry — and ETFs are now the easiest way for everyday investors to get in on it.

But here’s the catch: not all space ETFs are built the same. Some are diversified and stable. Others are leveraged and volatile. Some have paper-thin liquidity. And one is so heavily concentrated in a single rocket company that it essentially lives and dies by Rocket Lab’s stock price.

In this guide, we break down the 10 best space ETFs available in 2026 — ranked by AUM, performance, and risk-adjusted value — so you can invest smarter, not just louder.

Why Most Beginners Miss Out on the Space Boom

Here’s something most investors don’t realize: the commercial space industry is growing at a CAGR of over 9% annually, with projections putting the global market at over $1 trillion by 2030. And yet, the majority of retail investors have zero space exposure in their portfolios.

Why? Because buying individual space stocks is complicated. Which company wins the satellite race? Who gets the next NASA contract? What happens if a rocket fails on launch day?

These are legitimate concerns. And that’s exactly why space-focused ETFs exist — to let you invest in the entire sector without betting everything on one company.

Think of it this way: instead of picking whether SpaceX, Rocket Lab, or Boeing wins the space race, you just invest in all of them. If the industry grows, you grow with it.

If you’re interested in individual space stocks, check out our guide on the 10 best space stocks to buy for a deeper breakdown.

Why Space ETFs Are Having a Breakout Year in 2026

The numbers are staggering. UFO — the Procure Space ETF — posted a +101.5% one-year return as of 2026. ROKT followed closely at +90.3%. These aren’t speculative projections. These are verified, real-world performance figures from institutional-grade funds.

Several catalysts drove this surge:

Commercial satellite launches hit record highs, with mega-constellations like SpaceX’s Starlink expanding their global subscriber base.

Defense contracts for space-based surveillance and communications increased significantly across NATO-aligned nations.

Rocket Lab (RKLB) emerged as a credible challenger to SpaceX in the small-to-medium launch market, driving huge price appreciation in concentrated funds.

Meanwhile, investors who missed the AI wave of 2024 started rotating into the next high-growth theme — and space was sitting right there.

Top 10 Best Space ETFs in 2026 — from #10 to #1

#10 — DIPR: Corgi Space & Satellite Communications ETF

Expense Ratio: 0.35% | AUM: $3.93M

DIPR holds the title of the cheapest space ETF on the market with an expense ratio of just 0.35%. For cost-conscious investors who want basic space exposure, the low fee is attractive.

But here’s the reality: at under $4 million in AUM, DIPR is a micro-fund with serious liquidity risks. Wide bid-ask spreads and low daily trading volume make it difficult to buy and sell efficiently, especially during volatile market conditions.

Best for: Speculative, cost-focused investors who are comfortable with very low liquidity.

#9 — SPCI: Tuttle Capital Space Industry Income Blast ETF

Expense Ratio: 0.99% | AUM: $13.56M

SPCI is a niche, income-oriented space ETF — but the numbers don’t quite deliver on the “income blast” promise. With no dividend yield reported and an expense ratio nearing 1%, SPCI sits in an awkward middle ground: too expensive for pure growth, not generous enough for income seekers.

Its AUM of $13.56 million also keeps it in micro-fund territory, meaning liquidity concerns remain. Best treated as a speculative position within a diversified space ETF portfolio.

#8 — WARP: VanEck Space ETF

Expense Ratio: 0.50% | AUM: $49.31M

WARP brings the credibility of VanEck — a well-established asset manager — to the space ETF space (pun intended). Its expense ratio of 0.50% is reasonable, and with nearly $50 million in AUM, liquidity is meaningfully better than the bottom-tier options.

VanEck’s methodical approach to index construction means WARP holds a broadly diversified mix of satellite, launch, and defense companies. It won’t make you rich overnight, but it provides solid, steady-state space exposure without undue concentration risk.

#7 — ORBX: Global X Space Tech ETF

Expense Ratio: 0.50% | AUM: $53.80M

ORBX is managed by Global X, one of the more innovative ETF providers known for thematic funds. At 0.50% expense ratio and $53.8M AUM, it sits in the same tier as WARP — decent liquidity, competitive cost.

What sets ORBX apart is its focus on pure-play space technology companies, including satellite manufacturers, ground station operators, and space analytics firms. If you want targeted tech exposure over broader aerospace, ORBX delivers.

#6 — MARS: Roundhill Space & Technology ETF

Expense Ratio: 0.75% | AUM: $93.55M

With nearly $94 million in AUM, MARS crosses into meaningful territory. Roundhill Investments is known for bold, theme-driven ETFs — and MARS is no exception, blending space stocks with adjacent technology companies including those involved in satellite broadband and defense analytics.

At 0.75% expense ratio, it’s on the higher end for passive ETFs, but still within acceptable range for thematic funds. MARS is a solid mid-tier option for growth-oriented investors who want a blend of space and tech exposure.

#5 — ROKT: SPDR S&P Kensho Final Frontiers ETF

Expense Ratio: 0.45% | 1-Year Return: +90.31% | AUM: $242.56M | Dividend: 0.29%

ROKT is arguably the best risk-adjusted space ETF on this list. It offers:

+90.31% one-year return — among the best in the category

0.45% expense ratio — one of the lowest among performing funds

$242.56M AUM — strong institutional backing and healthy liquidity

The fund tracks the S&P Kensho Final Frontiers Index, which includes companies operating in space, ocean exploration, and other frontier industries. Its diversification beyond pure space reduces single-sector concentration risk while still capturing the upside of the space boom.

For beginner and intermediate investors, ROKT may be the single most efficient way to get space exposure in 2026.

#4 — RKLX: Defiance Daily Target 2X Long RKLB ETF

Expense Ratio: 1.29% | AUM: $315.75M | Dividend: 11.42%

RKLX is a leveraged ETF that delivers 2x the daily return of Rocket Lab USA (RKLB) stock. That 11.42% dividend yield sounds incredible — but it’s a product of the fund’s leveraged options strategy, not underlying business earnings.

This is not a buy-and-hold investment. Leveraged ETFs suffer from volatility decay, meaning their long-term performance diverges significantly from simply holding 2x the underlying stock over time.

RKLX belongs in the hands of experienced traders with a short-to-medium term thesis on Rocket Lab specifically — not in a beginner’s long-term portfolio.

Warning: RKLX is classified as a high-risk, leveraged product. Treat it accordingly.

#3 — ARKX: ARK Space & Defense Innovation ETF

Expense Ratio: 0.75% | 1-Year Return: +48.23% | AUM: $1.02B

ARKX crossed the $1 billion AUM milestone — a significant marker of institutional confidence. Managed by Cathie Wood’s ARK Invest, ARKX is an actively managed fund that holds space stocks alongside aerospace and defense companies with disruptive potential.

The +48.23% one-year return is strong but trails the passive funds UFO and ROKT. That said, ARKX offers something those funds can’t: active conviction-based portfolio management. If you believe in ARK’s research-driven approach, ARKX is a compelling choice.

Its holdings include companies working on autonomous aerospace systems, satellite internet, and orbital manufacturing — making it a broader play on the future of space commerce.

#2 — UFO: Procure Space ETF

Expense Ratio: 0.75% | 1-Year Return: +101.50% | AUM: $1.12B | Dividend: 0.32%

UFO is the best-performing space ETF in 2026. Full stop.

A +101.5% one-year return is extraordinary in any market environment — and UFO achieved it through hyper-focused exposure to pure-play space companies: satellite operators, launch providers, and ground segment businesses.

The fund’s top holdings include companies like Iridium Communications, Maxar Technologies, and Rocket Lab — names that directly drive revenue from space operations rather than simply using satellites as a business tool.

With $1.12B in AUM and a small dividend yield, UFO balances explosive growth with institutional credibility. The 0.75% expense ratio is reasonable for active-adjacent thematic exposure.

The caveat? High concentration means high volatility. UFO is not a smooth ride — but for investors with a strong stomach and a 3–5 year horizon, it’s one of the most compelling ETFs in any sector right now.

#1 — NASA: Tema Space Innovators ETF

Expense Ratio: 0.75% | 1-Year Return: +31.24% | AUM: $2.66B

NASA — the Tema Space Innovators ETF — is the undisputed leader of the space ETF universe by AUM, holding a commanding $2.66 billion in assets under management.

While its one-year return of +31.24% trails UFO and ROKT, NASA’s strength lies in scale and diversification. With more than $2.6 billion in the fund, institutional investors have voted with their capital — making NASA the most trusted and liquid option for space exposure.

Tema’s investment thesis centers on the full space value chain: launch vehicles, satellite manufacturing, space data analytics, in-space services, and defense-adjacent aerospace. It’s not just a bet on rockets — it’s a bet on everything space touches.

For long-term, buy-and-hold investors who want maximum liquidity, broad diversification, and institutional-grade space exposure, NASA is the #1 best space ETF to buy in 2026.

Key Risks to Consider Before Investing in Space ETFs

Space ETFs are growth-oriented, and growth comes with volatility. Before you invest, here’s what you need to know:

Volatility: Space ETFs routinely swing 30–50% in short periods. UFO’s +101% return is extraordinary — but the fund has also experienced major drawdowns.

Concentration Risk: Pure-play funds like UFO and the leveraged RKLX are heavily weighted in just a handful of companies. A single earnings miss can tank the entire ETF.

Liquidity Risk: Smaller funds like DIPR ($3.93M AUM) and SPCI ($13.56M AUM) have wide bid-ask spreads, making entry and exit more expensive than they appear.

Leverage Risk: RKLX uses 2x daily leverage. This amplifies both gains and losses, and volatility decay erodes long-term returns significantly.

Space ETFs are best treated as a satellite allocation — ideally 5–15% of a diversified portfolio. For related diversification ideas, explore our breakdown of the 10 best EV stocks to buy as another high-growth thematic play.

Conclusion: Which Space ETF Should You Buy in 2026?

The commercial space industry is no longer the future — it’s happening right now, and the best space ETFs to buy in 2026 give you a front-row seat.

For most investors, the clear standouts are:

NASA — Best overall: largest AUM, broadest diversification, highest institutional trust.

UFO — Best performance: +101.5% one-year return, pure-play space exposure, growing AUM.

ROKT — Best value: lowest expense ratio among top performers, +90.3% return, frontier diversification.

ARKX — Best for active management believers: $1B+ AUM, Cathie Wood’s conviction-based strategy.

If you’re a beginner, start with NASA or ROKT for a smooth, diversified entry point. If you’re chasing maximum upside and can handle the swings, UFO is the boldest bet.

Whatever you choose, the space economy is only going up from here. The only question is: are you on board?
