KEY POINTS
- The Global X Defense Technology ETF (SHLD) has grown to $8.6 billion in assets and is up 49% over the past year, while the U.S. Congress approved $900.6 billion in defense spending for fiscal 2026.
- NATO's European allies increased defense spending by 20% in 2025, and for the first time all 31 NATO members met the 2% of GDP commitment, driving sustained inflows into defense-focused funds.
- Traders should watch the European defense allocation cycle through Q3 as procurement contracts are awarded, with SHLD, ITA, and XAR positioned as the primary vehicles for capturing the rearmament trade.
Global defense spending hit $2.63 trillion in 2025, up from $2.48 trillion the prior year, and 2026 is accelerating the trend. The U.S. Congress approved $900.6 billion for defense in the current fiscal year. NATO's European allies increased their military budgets by 20% in 2025, and for the first time in the alliance's history, all 31 member nations met the 2% of GDP spending commitment. For thematic ETF investors, the defense trade has become the most durable and highest-conviction sector play of the year.
The Global X Defense Technology ETF (SHLD) exemplifies the shift. Launched in September 2023, the fund has grown to $8.6 billion in assets and delivered a 49% return over the trailing twelve months and roughly 15% year to date. SHLD's edge is its deliberate mix of domestic defense giants and European firms that are directly receiving the new NATO budget allocations — a construction that makes it the sharpest tool for capturing the rearmament wave on both sides of the Atlantic.
Why Thematic Flows Shifted From AI to Defense
The pivot is notable because defense ETFs have displaced artificial intelligence as the leading thematic category by flow momentum in 2026. State Street identified defense as the standout theme coming into the year, and the call has played out. SHLD gathered over $1 billion in January alone, a figure that dwarfed any single-month intake for the fund in 2024.
The catalyst is not complicated: real spending is flowing. Unlike AI, where ETF investors are making bets on future revenue growth and adoption curves, defense spending is legislated, budgeted, and contracted. The European rearmament cycle is particularly powerful because it represents a structural break from decades of underinvestment. Germany's special defense fund, the Zeitenwende initiative, has accelerated procurement timelines, and Poland, the Baltics, and Nordic nations are all running military budgets well above 2% of GDP.
The Iran conflict has only intensified the dynamic. With U.S. forces engaged in the Middle East and global supply chains disrupted, defense contractors are seeing order books swell. The iShares U.S. Aerospace & Defense ETF (ITA) has returned 49% from January 2025 through early May 2026, and the SPDR S&P Aerospace & Defense ETF (XAR) has delivered competitive returns on the back of mid-cap defense names that benefit from NATO's diversified procurement strategy.
Domestic vs. European Exposure
For traders choosing between vehicles, the distinction matters. ITA and PPA are weighted heavily toward U.S. prime contractors — Lockheed Martin, RTX, Northrop Grumman, and General Dynamics — that benefit from the $900.6 billion U.S. defense budget. SHLD, by contrast, includes European names like Rheinmetall, BAE Systems, and Leonardo that are direct beneficiaries of the NATO spending surge.
The European angle is where the incremental growth is fastest. European defense budgets are expanding from a lower base, and procurement cycles that were dormant for years are now active. Rheinmetall alone has seen its order backlog grow by more than 50% year over year. For traders who want maximum exposure to the rearmament thesis, SHLD's hybrid construction provides better diversification across the spending cycle than any single-country fund.
What Comes Next
The durability of this trade depends on whether defense budgets continue to rise or plateau. Current indicators suggest acceleration: the Iran conflict shows no sign of rapid resolution, NATO's June summit is expected to raise the spending target above 2%, and several nations have signaled commitments to 3% of GDP by 2030. The key event window is Q3 2026, when European procurement contracts for the next fiscal cycle are awarded. If order flow confirms the budget promises, defense ETFs have room to run. If spending stalls at the commitment stage without contract execution, the premium valuations in the sector become vulnerable.
