Defence ETF exposed to Drones, Space, Robotics
If you are specifically targeting higher beta (higher volatility and potential for market-beating returns), the ARK Space & Defense Innovation ETF (ARKX) is generally your strongest choice among the major thematic funds.
While traditional defense ETFs like ITA provide stability, they often have a beta closer to 1.0. In contrast, thematic space and robotics funds track smaller, more aggressive "pure-play" companies that are more sensitive to market swings.
1. High-Beta Comparison (as of Feb 2026)
| ETF | Approx. Beta | Core Exposure | Risk Profile |
| 1.32 | Drones, Robotics, AI, Reusable Rockets | Highest: Extremely volatile; high growth/high risk. | |
| 1.02 | Deep Space, Submersibles, Unmanned Systems | Moderate: Tracks the Kensho Final Frontiers Index; steady but innovative. | |
| ~1.15 | Satellite Ops, Rocket Mfg, Space Imagery | High: Very pure-play space; less diversified in robotics/drones. | |
| 0.99 | Lockheed, Boeing, RTX, GE | Low: Heavy on established "Prime" defense contractors. |
2. Why ARKX Leads in Beta
ARKX is actively managed by Cathie Wood’s ARK Invest, which intentionally seeks out "disruptive innovation." This results in a higher concentration of mid-cap and small-cap stocks that move significantly more than the S&P 500.
Drones & Robotics: ARKX holds heavy positions in companies like
(drones) andAeroVironment (AVAV) (robotics).Teradyne (TER) Space Pure-Plays: It has a high conviction in
, which is a significantly more volatile "new space" stock compared to the Boeing or Lockheed components found inRocket Lab (RKLB) .ITA
3. Exposure to Your Specific Bets
Drones: For pure-play drone defense,
actually has a unique sub-index (the S&P Kensho Drones Index) that specifically targets unmanned aerial and underwater vehicles. It is more "rules-based" than ARKX but has slightly lower volatility.ROKT Robotics: ARKX is the leader here. It categorizes robotics as an "enabling technology" for space and defense, making it a core part of its
strategy.Big Ideas 2026 Space:
provides the "purest" space exposure, focusing on companies that derive a majority of their revenue from space-related activities, which often results in high beta during periods of industry news (like SpaceX launches or NASA contract wins).UFO
The Verdict: If you want the "highest octane" exposure to these sectors, ARKX is the winner due to its 1.32 beta. However, if you want a more systematic, lower-cost exposure to the technical side of drones and deep-sea robotics,
