My lists of ETFs that hold SpaceX, Rocket Lab, AST SpaceMobile and Intuitive Machines are some of the most read pages on this site. So let's keep going. Next up: Firefly Aerospace.
Firefly is a Texas rocket and spacecraft company. Its Blue Ghost lander touched down on the Moon on March 2, 2025, the first fully successful commercial Moon landing. It flies its own small rocket, Alpha, and is building a bigger one called Eclipse with Northrop Grumman. It went public on Nasdaq in August 2025 under the ticker $FLY.
It's also been a rough ride for shareholders. The stock closed around $17.63 on October 30, 2026, down from a 52-week high of $62.17. Market cap is about $2.95 billion. That kind of swing is exactly why a lot of people would rather own it inside a fund. Here's every way to do that.

The Full List: ETFs That Hold $FLY, Ranked by Weight
Same format as the other lists. The last column is the one I care about most: how many dollars of Firefly you actually own for every $10,000 you put in.
| ETF | Fund | $FLY Weight | $SPCX Weight | Expense Ratio | $FLY per $10K |
|---|---|---|---|---|---|
| $WARP | VanEck Space ETF | 4.15% (#9) | 21.82% | 0.50% | ~$415 |
| $ORBX | Global X Space Tech ETF | 4.08% (#8) | 23.95% | 0.50% | ~$408 |
| $NASA | Tema Space Innovators ETF | 3.66% (#9) | 26.87%* | 0.75% | ~$366 |
| $MARS | Roundhill Space & Technology ETF | 2.87% (#10) | 24.90% | 0.75% | ~$287 |
| $UFO | Procure Space ETF | 1.61% (#21) | 15.17% | 0.75% | ~$161 |
Sources: StockAnalysis.com holdings data, updated October 27, 2026 for $NASA, October 28 for $ORBX, $WARP and $UFO, and October 30 for $MARS. Expense ratios from StockAnalysis.com fund pages. *$NASA holds SpaceX two ways: about 17.75% through a special purpose vehicle and about 9.12% in listed $SPCX shares. Weights change every day.
Three things jump out. First, the two cheapest funds, $WARP and $ORBX at 0.50%, hold the most Firefly. That's the same pattern I found with Intuitive Machines. Second, nobody holds more than about 4%. And third, unlike Intuitive Machines, neither ARK fund shows Firefly in its top 25.
Space ETFs With the Biggest Firefly Positions
$WARP VanEck Space ETF
The most Firefly of any diversified fund I found, at 4.15%, its 9th biggest holding. It's also the most concentrated fund here at just 22 names. SpaceX is 21.82% and Rocket Lab a big 13.17%. Planet Labs (4.10%) and Redwire (4.04%) sit right next to Firefly, so you get the newer space names at nearly equal weights. About $39.6 million in assets, launched May 2026.
$ORBX Global X Space Tech ETF
Basically tied with $WARP at 4.08%, Firefly's 8th spot in the fund. The top is SpaceX (23.95%), Rocket Lab (9.55%) and AST SpaceMobile (7.55%). It also holds Redwire (3.96%) and Planet Labs (3.33%). The downside: it's small, at about $37.2 million in assets, and only launched in April 2026.
$NASA Tema Space Innovators ETF
The big one. At about $985 million, $NASA dwarfs the other new space funds, and Firefly is its 9th biggest holding at 3.66%. The thing to know: about 18% of the fund is a SpaceX special purpose vehicle, plus another 9% in listed $SPCX. If you care about a fund sticking around, size matters, and this one has it.
$MARS Roundhill Space & Technology ETF
SpaceX first at 24.90%, Rocket Lab second, Viasat third. Firefly sits 10th at 2.87%. About $41.9 million in assets. For Firefly exposure specifically, it gives you less than $WARP or $ORBX and charges more.
$UFO Procure Space ETF
The oldest pure space fund, launched in April 2019, with about $463 million in assets. Firefly is just 1.61%, its 21st biggest holding. SpaceX leads at 15.17%, followed by Trimble and Viasat. The most diversified way to own Firefly, and also the most diluted.

Popular ETFs That Don't Hold It
Here's the list of funds people assume own Firefly that don't show it among their top 25 holdings in StockAnalysis.com data from late October 2026:
- $ARKX (ARK Space & Defense Innovation ETF)
- $ARKQ (ARK Autonomous Technology & Robotics ETF)
- $ROKT (SPDR S&P Kensho Final Frontiers ETF)
- $XAR (SPDR S&P Aerospace & Defense ETF)
- $ITA (iShares U.S. Aerospace & Defense ETF)
- $SHLD (Global X Defense Tech ETF)
The $ARKX one surprised me a little, since it owns Intuitive Machines. Its top holdings are SpaceX (10.64%), L3Harris and Kratos. The big defense funds are led by GE Aerospace, RTX and Lockheed. A $3 billion rocket company just doesn't move the needle there. If you own one of those "for the space exposure," you're mostly buying aerospace giants.
For a full breakdown of the older funds, see $UFO vs $ARKX vs $ROKT.
$FLYT: The 2x Firefly ETF
For traders, Tradr launched $FLYT (Tradr 2X Long FLY Daily ETF) on October 22, 2025. It aims for 2x Firefly's daily move, charges 1.30% and has about $9.8 million in assets.
Look at what happened to it. $FLYT's 52-week high was about $58.52. On October 30, 2026 it traded around $3. That's a drop of roughly 95%, while $FLY itself fell about 72% from its 52-week high. It resets daily. In a stock that swings this hard, daily leverage doesn't just double your losses, it compounds them. This is a short-term trading tool, not a way to own the company.
What You're Actually Buying With Firefly
Before buying any fund for one name, I like to know what the name actually is. Quick version:
- Blue Ghost: its lunar lander. Mission 1 launched January 15, 2025 and landed on March 2, 2025.
- Alpha: its small rocket. It failed in April 2025, then an Alpha first stage exploded during a ground test in Texas on September 29, 2025, with no one hurt. Alpha returned to orbit in March 2026.
- Eclipse: the medium-lift rocket it's building with Northrop Grumman. As of March 2026, first flight was expected in 2027.
- The numbers: about $287 million in revenue over the last 12 months, up 179%, but a net loss of about $370 million. Next earnings are expected November 10, 2026.
So you've got a company with a real Moon landing on its resume, a rocket that's had setbacks, a bigger rocket still on the drawing board, and growing revenue with big losses. That's a lot of risk to concentrate in one stock. A basket spreads it out.
The Catch: You Get 5 to 9 Times More SpaceX
This is the part most people miss. If you buy a space ETF to get Firefly, what you're mostly buying is SpaceX.
That's not necessarily bad. SpaceX is the most valuable space company on the planet, and Firefly even launched Blue Ghost on a SpaceX Falcon 9. But if your thesis is "I want the next launch company," know that it's a small slice of what you're paying for. Look at the top three holdings before you buy, not the fund's name.
For the bigger picture, see our 10 top space ETFs to buy in 2026 and $NASA vs $MARS vs $ORBX vs $WARP, where I compared the four new 2026 funds head to head.
Which Approach Fits You
- "I want the most Firefly in a fund, for the lowest fee." $WARP or $ORBX, both 0.50%.
- "I want a space fund big enough to stick around." $NASA, at about $985 million.
- "I want the broadest space basket." $UFO, 67 holdings, $FLY at about 1.6%.
- "I want to trade the daily moves." $FLYT. Short term only, and read the section above first.
- "I own $ARKX, $ITA or $XAR." You don't have meaningful Firefly exposure. Just know it.
My Take
I'm a dividend investor first. I reached financial freedom by building income, not by betting on rocket launches. Firefly doesn't pay a dividend, and a company losing hundreds of millions a year while building a new rocket won't anytime soon.
So if I wanted exposure, I'd keep it small, and I'd rather get it through a basket than the single stock. And between the funds, I'd look at the fee first. $WARP and $ORBX hold more Firefly than $MARS and $UFO and charge 0.50% instead of 0.75%. That difference compounds.
