STOCKHOLM — Global military spending climbed to a record $2.718 trillion in 2024, sharpening investors’ focus on how quickly governments can turn bigger budgets into orders for defense contractors, Jan. 8, 2026.
Why defense contractors are winning this spending cycle
SIPRI’s latest estimates show world military expenditure has risen every year for a full decade, with 2024 marking the steepest year-over-year jump since at least 1988. That pace matters to defense contractors because it tends to lengthen multiyear procurement plans and reduce the risk that a single election cycle disrupts production lines for missiles, air defenses, artillery, ships and aircraft.
Reuters reporting on the sector has highlighted how the “booming” market is spilling into backlogs and factory expansions as governments hunt for faster deliveries and larger inventories. For many defense contractors, the near-term story is less about brand-new platforms and more about munitions, sustainment and upgrades—categories that can scale quickly when money shows up. Reuters’ visual breakdown of the arms market tracks how that demand has broadened across regions.
How defense contractors are powering outsized index gains
The market’s enthusiasm shows up in the tape. Yahoo Finance cited the S&P 500 Aerospace & Defense Index gaining more than 50% over the past year, underscoring momentum that has outpaced many general-equity measures. A look at defense-focused ETFs and the sector’s run points to investor appetite for firms tied to procurement and replenishment cycles.
Still, “defense contractors” is not a single trade. Prime contractors often benefit from big-ticket programs and classified work, while second-tier defense contractors can outperform when supply chains tighten and spending shifts toward electronics, sensors, propulsion and munitions components. The result can be uneven stock performance even as the sector rises.
Continuity check: this didn’t start in 2024
In 2023, global military expenditure hit $2.443 trillion, then a record, as conflicts and rising tensions accelerated spending. SIPRI’s 2023 spending fact sheet captured that earlier inflection point.
Zoom out further and the scale becomes clearer: SIPRI put global military expenditure at $1.776 trillion in 2014—less than two-thirds of today’s level. SIPRI’s 2014 trends fact sheet is a reminder that defense contractors have been operating within a long, uneven buildup rather than a one-year spike.
What defense contractors are watching next
The next leg depends on execution: supply constraints, skilled labor and industrial capacity can cap how fast defense contractors convert demand into revenue. Deloitte’s 2026 outlook flags a sector entering a new phase of expansion tied to digital capabilities, sustainment and rising demand across defense and commercial aerospace. Deloitte’s aerospace and defense outlook lays out where investment is likely to concentrate.
Political risk is rising, too. In the U.S., President Donald Trump has recently threatened restrictions targeting dividends and buybacks in the defense sector—an approach that could reshape how defense contractors balance shareholder returns with capacity spending. Market reaction to proposed limits on payouts showed how quickly policy headlines can move the group.
For now, the basic equation remains intact: rising global budgets are creating a bigger pool of work, and defense contractors that can deliver on time—especially in munitions and air defense—are positioned to keep benefiting from the spending surge.
