KEY POINTS
- The REX Drone ETF (DRNZ) delivered a 120% one-year return, fueled by a 240-fold increase in Pentagon autonomous drone spending to $54 billion under the Defense Autonomous War Group program.
- The Global X Defense Technology ETF (SHLD) has gathered over $1 billion in assets as eight new defense ETFs launched in the past 18 months, reflecting a structural reallocation from AI-themed to defense-themed products.
- Traders should watch the FY2027 defense authorization debate in Congress—the spending trajectory for autonomous systems will determine whether these returns are a one-cycle event or a multi-year theme.
The REX Drone ETF (DRNZ) has returned 120.1% over the past twelve months, making it the best-performing thematic ETF in the United States by a wide margin. The Global X Defense Technology ETF (SHLD) is up 23.4% over the past three months alone and has crossed $1 billion in total assets. In a year where AI-themed ETFs have struggled with valuation compression and sector rotation, defense and drone funds have emerged as the thematic trade that actually delivered.
The catalyst is not abstract. The Trump administration's Defense Autonomous War Group program allocated $54 billion to autonomous drone procurement in the current fiscal year, a staggering increase from $225 million the prior year—a 240-fold jump that transformed a niche defense category into one of the fastest-growing budget line items in Pentagon history. The spending reflects lessons drawn from the Ukraine conflict, where low-cost drones proved capable of destroying armored vehicles costing hundreds of times more, and from escalating tensions in the Indo-Pacific that are driving demand for autonomous surveillance and strike platforms.
Inside the Holdings
DRNZ tracks 41 companies spanning drone manufacturing, autonomous navigation, sensor technology, and enabling components. The fund's top holdings include AeroVironment (AVAV), Kratos Defense (KTOS), and L3Harris Technologies (LHX)—a mix of pure-play drone manufacturers and diversified defense contractors with significant autonomous systems divisions. The fund has gained 29% in the last three months alone, outpacing even the strong broader defense sector.
SHLD takes a wider approach, running a modified market-cap-weighted index that captures pure-play defense names benefiting from rising global military spending. Its holdings span big data, cybersecurity, robotics, and fuel systems alongside traditional drone and UAV companies. The fund's broader exposure means it captures more of the overall defense spending cycle but dilutes the concentrated bet on autonomous systems that has made DRNZ the year's standout.
The Thematic Rotation Is Real
Eight new defense ETFs launched in 2025 and 2026, with seven of the eight carrying global or international exposure, reflecting a recognition that European and Asian rearmament is just as investable as U.S. defense spending. The rush of new products is drawing capital away from AI-themed ETFs that dominated flows in 2024. Thematic investors are rotating, not retreating—they are simply shifting from artificial intelligence to autonomous warfare.
The risk for drone ETFs is concentration. DRNZ's 41-name portfolio is narrow by ETF standards, and several of its top holdings trade at 40-60x forward earnings, pricing in years of revenue growth that depends on sustained government procurement. If the FY2027 defense budget reduces autonomous spending—even modestly—the valuation air comes out quickly.
What Comes Next
The FY2027 National Defense Authorization Act debate begins in earnest this summer. Congressional hawks have signaled support for expanding the Autonomous War Group program, but deficit concerns and competing priorities could cap the growth rate. Traders riding DRNZ should treat the NDAA markup in the House Armed Services Committee, expected in late June, as a binary event. A spending increase keeps the rally alive. A plateau or cut triggers the first meaningful correction in a fund that has gone essentially straight up for twelve months. For new entries, a pullback to the 50-day moving average offers a better risk-reward than chasing at current levels.
